Table of Contents

Lathe Machine is known as one of the oldest machine tools in the production machine. This Machine is also known as the mother of all machines.

In these articles we will try to learn Definition, Parts, Operation we perform on it, The Types, Specification advantages, disadvantages, and application of lathe machine.

Lathe Machine Introduction:

Lathe machine is probably the oldest machine tool know to mankind. Its first use dates back to 1300 BC in Egypt. The first lathe was a simple Lathe which is now called a two-person lathe.

In this one person would turn the wood workpiece using rope and the other person would shape the workpiece using a sharp tool.

This design was further improved by the Ancient Romans who added the turning bow and lather the paddle (as there in the sewing machine) was added.

Further during the industrial revolution Steam Engines and water wheel were attached to the Lathe to turn the workpiece to a higher speed which made the work faster and easier.

Then in 1950 servo mechanism was used to control the lathe machine.

From this crude begging and over a period of more than two centuries, the modern engine lathe has evolved. Now we have the most advanced form of the Lathe Machine which is the CNC Lathe Machine.

HENRY MAUDSLAY, a British Engineer is considered as the inventor of the metal lathe.

Lathe Machine Definition:

A lathe machine is a machine tool which removes the undesired material from a rotating workpiece in the form of chips with the help of a tool which is traversed across the work and can be feed deep into the work.

A lathe is a machine which is one of the most versatile and widely used machine tool all over the world.

Lathe is also known as the ‘ Mother of all Machines’ .

Nowadays, Lathe Machine has become a general-purpose machine tool, employed in production and repair work, because it permits a large variety of operations to be performed on it.

Lathe Machine Parts and thre 

The various parts of the Lathe Machine are:

The bed of the lathe machine is the base on which all the other parts of the lathe are mounted.

The bed is made from Cast iron or nickel cast iron alloy and is supported on broad box-section columns.

Its upper surface is either scraped or grounded and the guiding and the sliding surfaces are provided.

The bed consists of heavy metal slides running lengthwise, with ways or v’s forced upon them. It is rigidly supported by cross griths.

The three major units mounted on bed are:

The scrapped or the ground guiding along with the sliding surfaces on the lathe bed ensure the accuracy of the alignment of these three units.

Headstock is present on the left end of the bed.

The main function of the headstock is to transmit power to the different parts of the lathe.

It supports the main spindle in the bearing and align it properly. It also houses a necessary transmission mechanism with speed changing levers to obtain different speeds.

Accessories mounted on the headstock spindle are:

• Three jaw chuck.
• Four jaw chuck.
• Lathe center and lathe dog.
• Collet chuck.
• Face Plate.
• Magnetic chuck.
• Tailstock :

Tail stock is a movable casting located opposite to the headstock on the way of the bed. The basic function of the tailstock is:

• To support the other end of the work when being machined.
• To hold a tool for performing operations like drilling, reaming, tapping, etc.

It consists of the dead centers, the adjusting screws and the handwheel. The body of the tailstock is adjustable on the base which is mounted on the guideways of the bed and can be moved to and fro.

Carriage is located between headstock and tailstock. The basic function of the carriage is to support, guide and feed the tool against the job during operation.

It consists of 5 main parts:

• Saddle: It is an H-shaped casting mounted on the top of the lathe ways. It provides support to cross-slide, compound rest and tool post.
• Cross Slide:

Cross slide is provided with a female dovetail on one side and assembled on the top of the saddle with its male dovetail.

The top surface of the cross slide is provided with T slots to enable fixing of rear tool post or coolant attachment.

Carriage basically provides a mounted or automatic cross-movement for the cutting tool.

• Compound Rest :

Compound rest is present on the top of the cross slide. It supports the tool post and cutting tool in its various positions.

Compound rest is necessary for turning angles and boring short tapers and forms on forming tools.

• Tool Post :

The tool post is mounted on the compound rest. It is used to hold the various cutting tool holders.

The holders rest on a wedge which is shaped on the bottom to fit into a concave-shaped ring(segmental type), which permits the height of the cutting edge to be adjusted by tilting the tool.

It is fixed on the top slide. It gets its movement by the movement of the saddle, cross slide, and top slide.

The three types of tool post which are commonly used are:

• a) Ring and rocker tool post :

It consists of a circular tool post with a slot for accommodating the tool or tool holder .

b)Quick change tool post

• c) Squarehead tool post.
• The Apron :

The Apron is fastened to the saddle and hangs over the front of the bed.

Apron consists of the gears and clutches for transmitting motion from the feed rod to the carriage, and the split nut which engages with the lead screw during cutting threads.

Two types of Apron are extensively used:

• i) Incorporating drop worm mechanism.
• ii) Friction or dog clutches.
• Chuck – Chuck is basically used to hold the workpiece, particularly of short length and large diameter or of irregular shape which can’t be conveniently mounted between centers. It can be attached to the lathe by screwing on the spindle nose.

Four d i fferent types of chucks are most commonly used in Lathe:

• Idependent or four jaw chuck:

It is used for irregular shapes, rough castings of square or octagonal in such jobs, where a hole is to be positioned off the center.

It consists of four jaws and each jaw is independently actuated and adjusted by a key for holding the job.

• Three jaw or universal chuck:

It consists of three jaws which move simultaneously by turning a key and the workpiece automatically remains in the centerof the chuck opening.

It is used for holding round, hexagonal bar or other symmetric work.

• Collet chuck

It is mostly used in the places where production work is required such as in Capstan Lathe or automats.

It is used for holding the bars of small sizes (below 63mm).

• Magnetic chuck:

They are of permanent magnet type or electrically operated. In lathe it does not have a widespread use.

Feed rod is a power transmission mechanism used for precise linear movement of the carriage along the longitudinal axis of the lathe.

In some lathe machine instead of feed rod lead screws are used.

• H) Lead screw :

Lead screw is used mostly in the case when threading operation are to be performed on lathe.

As we know for threading operation requires rotational movement of the job (work piece) and the linear movement of the tool (tool post).

So rotation of the job is obtained by the chuck and the desired linear motion of the tool-post(asthe lead screw drives the saddle when it is engaged) is provided with the help of lead screw.

Working Principle of the Lathe Machine :

A Lathe works on the principle of rotating the workpiece and a fixed cutting tool.

The workpiece is held between two rigid and strong supports called center or in a chuck or in face plate which revolves.

Lathe removes the undesired material from a rotating workpiece in the form of chips with the help of a tool which is transverse across the work and can be fed deep in the work.

The main function of the lathe is to remove the metal from a job to give it the required shape and size.

The normal cutting operations are performed with the cutting tool fed either parallel or at right angles to the axis of the work.

The cutting tool can be fed at angle relative to the axis of the work for machining tapers and angles.

Products which can be made from lathe machine are :

A variety of products can be made from the lathe machine. Some of them are:

Nuts, bolts, piston, Ram, pump part, electric motor parts, sleeves, Air craft parts, gun barrels, candlesticks, train parts, cue sticks, wooden bowls, baseball bat, crankshaft and many more things.

Types of Lathe Machine :

The widely used type of Lathe Machine can be classified as below:

• Engine Lathe or center Lathe.
• Speed Lathe.
• Turret lathe.
• Capstan Lathe.
• Tool room Lathe.
• Bench Lathe.
• Gap bed lathe.
• Hollow spindle Lathe.
• Vertical Turret Lathe.
• Engine Lathe or centre Lathe :

Engine lathe is the most important tool in the Lathe family and by far the most widely used type of Lathe machine.

Its name is derived from the fact that early machine tools were driven by separate Engines or central engine with overhead belt and shafts.

The operations which can be performed by the Engine Lathe machine are Turning, facing, grooving, knurling, threading, and many more operations can be performed by it.

Engine lathe consist of headstock, Tailstock, bed, saddle, carriage and other parts.

• The headstock encloses the spindle and motor. It also consists of the gear and pulleys, which are used to change the gear speed and the feed rate.
• Tailstock is provided to facilitate holding the work between centers and permit the use of tools like drills, taps, etc.
• The cutting tool can be fed both in cross and longitudinal direction with reference to the lathe axis with the hep of the feed rod and the lead screw.

The Engine Lathe are available in sizes to handle to 1m diameter jobs and 1 to 4m long.

• ii) Turret Lathe :

It is a production machine that is used for the production of products on a large scale.

It basically handles heavy-duty workpieces.

The distinguishing feature of this type of lathe is that the Tailstock is replaced by hexagonal Turret.

In it, the several tools are set up on a revolving turret to facilitate in performing a large number of operations on a job with minimum wastage of time.

The turret usually accommodates 6 tools for different operations like drilling, countersinking, reaming, tapping, etc, which can be brought into successively working positions by indexing the turret.

Turret lathe are basically used for repetitive batch production .

• Capstan Lathe :

Capstan Lathe are similar to the Turret lathe. It is used for the mass production of the light duty workpiece.

It incorporates capstan slide which moves on auxiliary slide and can be clamped in any position.

It is best suited for the production of the small parts because of its light weight and short stroke of capstan slide.

• Speed Lathe :
• It is the simplest form of the lathe and consists of a simple Headstock, tailstock and a tool post.
• It has no gearbox, lead screw and carriage.
• It has a very high speed of the headstock spindle. The speed of the spindle ranges from 1200 to 3600rpm.
• Tools are hand operated. Cone-pulley is the only source provided for speed variation of the spindle.
• Speed Lathes are intensively used in wood turning, metal spinning and polishing operation.
• Tool Room lathe :
• Tool Room lathe is a modern engine lathe which is equipped with all the necessary accessories for the accurate tool room work.
• It is best suited for the production of small tools, dies, gauges, etc.
• It is a geared head driven machine with considerable rage in spindle speed and feeds. Its speed can range from very low to a very high speed of up to 2500 rpm.
• Bench Lathe :

Bench Lathe machine is a type of small lathe machine which has all the parts of the engine Lathe machine and speed lathe machine.

It is mounted on a work bench and is used for doing small precision and light jobs.

• Special purpose Lathe machine :

Special purpose lathe machine is used for performing the specific special tasks which cannot be performed by ordinary lathe. Some type of special purpose Lathe are as follow:

• Gap bed lathe:

In gap bed lathe, gap is provided over the bed near the headstock to handle the job having flanges or some other protruding parts.

Mostly a removable portion is provided in the bed so that when it is not required it can be inserted.

• Wheel lathe:

Wheel lathes is special purpose lathe machine which is used for finishing the journals and turning the tread on locomotive wheels.

• T- Lathe machine:

T- Lathe machine is a type of machine which has T shaped bed and is used in the aerospace industry for the machining of the rotors of the jet engine.

Viii) Automatic Lathe Machine :

As the name suggest automatic Lathe machine is machine in which the complete work and the job handling movements required for the completion of the job is done automatically.

They are heavy duty, mass production and high-speed machine.

• CNC Lathe Machine :

Computer Numeric Control(CNC) is the most advanced form of the lathe machine.

CNC lathe machine produces the most accurate products as compared to the other type of the lathe machine.

In CNC Lathe machine program are being fed to the computer system which controls the overall working of the lathe.

CNC lathe machines are used for large scale Production.

Semi- skilled workers are required for the operation of this machine.

Operations which can be performed on the Lathe Machine:

The operations which can be performed on

• Taper turning
• Eccentric turning
• Scroll cutting

Let’s start discussing them one by one:

Turning is the most common operation performed on the lathe.

Turning is a machining operation in which the diameter of the workpiece is being reduced by removing the excess material from the outer diameter of the job(workpiece) which is mostly cylindrical or conical in shape.

Turning operation results in good surface finish of the metal.

The various type of turning operation are:

i) Tapered Turning :

Tapered Turning is a machining process in which the cylindrical jobs are being machined to produce a conical surface.

In taper Turning the tapered component will be produced.

The various methods used for Taper Turning are:

• Compound Rest Method
• Tail stock Method.
• Taper Turning Attachment method
• Form tool Method.

Let’s discuss each method in brief:

• Taper Turning Attachment Method:

In taper turning attachment method the slide ways are tilted by an angle equal to the taper angle of the component so that the saddle is automatically tilted and when the saddle is moving on the slide ways it produce tapered component.

• It can be used for both internal, external operation.
• 1 degree accuracy can be produced.
• Maximum taper angle which can be produced is 8 degree.
• Maximum taper length of the component in one sitting is 235mm.
• Compound Rest Method:

In compound Rest Method the compound rest is swiveled by an angle equal to the required taper angle on the component.

Any taper angle can be produced by this method and both internal and external taper turning operations can be performed by this method.

• Tail stock method:

The method is used for producing only external tapers

In this method the tailstock is moved from its middle position to one side of the bed, which makes the workpiece tilted with respect to the lathe axis and feed.

Thus, when the tool moves it cuts the workpiece at an angle to the axis creating taper.

• Form Tool method:

Form tool method is used for producing external tapers only.

Formtool method is a type of method in which the shape of the tool is same as that the shape of the component to be produced.

Whatever the angle on the tool that can be produced on the component.

Accuracy produced on the component depends upon the accuracy present on the tool.

It is mostly used in the chamfering operation.

• ii) Shoulder Turning:

Shoulder Turning is used in the case where several diameters are to be turned on the workpiece.

The surface forming the step from one diameter to the other is called as the shoulder.

There are four kind of shoulder:

A right-cut tool is used to make the square shoulder.

iii) Facing operation :

Facing is a process in which the end of the workpiece is being machined by the tool which is at a right angle to the axis of the rotation of the workpiece.

Facing is frequently the first operation performed in the production of the workpiece and often the last. We can relate it to the phrase” ending-up”, which will help us in remembering its sequence.

iv) Thread cutting operation:

Thread cutting is a type of operation in which the threads are being cut on the internal and the outer surface of the workpiece as per the requirement.

In the thread cutting operation only the automatic feed is given.

The automatic feed required for the thread cutting operation is given by using lead screw and the feed gear box.

127 toothed gear is used for producing Metric threads on engine Lathe.

Feed of the lead screw has to be changed in order to get different pitch of thread on the job.

Job speed during threading is up to 1/4 th of the job speed during turning.

v ) Parting :

Parting is operation in which the deep groves are being made on the parent material to remove the specific portion from the parent material resulting in dividing the workpiece into two or more parts.

vi) Chamfering :

Chamfering is the operation of beveling the extreme end of a workpiece.

Chamfering is provided for:

• Better look.
• To enable the nut to pass freely on threaded workpiece.
• To remove burrs
• To protect the end of the workpiece from being damaged.

Chamfering is done usually after knurling, thread cutting etc…

vii) Knurling :

The process of making the surface of the work piece rough by embossing(impressing) a diamond shaped regular pattern on the surface by making use of a knurling tool is called as knurling operation.

Knurling is done at a lower speed and the plenty of oil is used.

Knurling provides effective gripping surface on workpiece to prevent it from slipping when operated with hand.

Viii) Drilling Operation :

Drilling operation is a type of machining operation which is used to remove the material from the workpiece by making use of drill bit, which is held stationary in the Tailstock. Finally creating a hole in the work piece.

Drill bits are generally made up of high-speed steels and carbon steels.

• IX) Boring :

Boring is an internal turning operation used for enlarging the existing holes by some amount. It can further be divided as:

• Counter boring:

Contour boring is an internal turning operation used for enlarging the end of the holes.

• Counter sinking:

Counter Sinking is the operation of conical enlargement of the end of the hole.

It requires a large size drill bit than that required for hole.

X) Reaming:

Reaming is machining process which is done after drilling to make internal holes of very accurate diameter.

Reaming removes very small amount of material from the holes which are already drilled.

Specification of the Lathe :

In order to specify the lathe completely the following parameter should be included:

• a) Length between the two center : It is the measure of the maximum length of the workpiece that can be fixed between the lathe center.
• b) Height of the center: The distance between the lathe axis and the lathe bed is called the height of the center.
• c ) Swing Diameter over the bed: It is the maximum diameter of the workpiece that can we turned on a lathe without hitting the lathe bed.
• D) Maximum bar diameter:

It is the maximum diameter of the workpiece that can be passed through the hole in the headstock.

Other factors for the lathe specification are:

• i) Tailstock sleeve travel.
• ii) Metric thread pitches.

iii) Leadscrew Pitch.

• iv) Motor horse power and RPM.
• v) shipping dimension— length x width x height x weight.

Appication of Lathe Machine :

The application of Lathe Machine is widespread, I am listing some of the application of the Lathe Machine:

Metal working operations, metal spinning, thermal spraying, in automobile industry mainly in the crankshaft, wood turning, Glass turning operation, for forming screw threads, also used for reclamation of the parts, and many more…

A CNC lathe machine finds extensive use in the several tasks being performed by it in various industries like:

• Power Generation
• Automobile industries.

Advantages of the Lathe machine :

Lathe Machine has numerous advantages, some of them are:

i) High Quality Products:   Lathe machine specially the CNC Lathe machine produce final products with high quality .

• ii) High Speed: The machining in the lathe can be done a very high speed specially in automatic and CNC lathe machine.

iii) Saves time: Lathe machine because of its extensive high speed and high accuracy saves a lot of time, resulting in the increased production.

iv) Saves Money: Lathe machine helps in reducing the cost of machining because less operators are required for machining.

Disadvantages of Lathe Machine :

• i) Initial cost is very high.
• ii) High skilled operators are required for the initial setup of CNC machine.

iii) Control systems are complex.

iv) CNC machine cannot be used for small scale production method.

INTRODUCTION:

In the Mechanical Engineering field Lathe machine plays an important role in Manufacturing. In this article, I am going to discuss the Lathe machine in detail.

• A lathe is a machine tool which is used to remove unwanted metals from the work piece to give desired shape and size.
• Lathe machine is one of the most important machine tools which is used in the metalworking industry.
• It operates on the principle of a rotating work piece and a fixed cutting tool.
• The cutting tool is feed into the work piece which rotates about its own axis causing the workpiece to form the desired shape.
• It is also known as ” the mother/father of the entire tool family” .
• It was invented by   DAVID WILKINSON ( 05 Jan. 1771 – 03 Feb. 1852).

• The machine tool that ‘s used to remove unwanted metals from the work piece to give the desired shape and size so called ” Lathe machine “ .
•  Lathe machine is also known as “ Center Lathe ” because of two centers between which the job can be held and rotated.

Functions of lathe Machine

• The main function of Lathe machine is to remove excess material in the form of chips by rotating the work piece against a stationary cutting tool.
• This is accomplished by holding the work securely and rigidly on the machine and then turning it against cutting tool which will remove metal from the work.
• To cut the material properly the tool should be harder than the material of the work piece, should be rigidly held on the machine and should be fed or progress in a definite way relative to the work.

Main Parts of lathe Machine

• In a lathe machine every individual part performs an important task.
• Some important parts of a lathe machine are as follows:

Working Principle of lathe machine

  principle.

• A lathe is a machine tool which use to removes unwanted materials from a work piece in the form of chips with the help of a tool that travels across the work piece and can be fed deep in work.

• When the tool is moved parallel to the work-piece then the cylindrical surface is formed .

• If the tool is moved inclined to the axis then it produces a tapered surface and so calls as taper turning.

• It holds the work between two supports so call as centers.
• Face plate or Chuck are using for holding the work.
• Face plate or Chuck are mounted on the machine spindle .
• The cutting tool is holding with the help of Tool post.
• The movement of the job is rotating about the spindle axis .
• Against the revolving work, the tool is feed.
• The tool   moves either parallel or inclination to the work axis.

      iii. Profiling

      iv. External grooving, etc.

i. Tapers and Taper Turning  

• A taper may be define as a uniform increase or decrease in diameter of a piece of work measured along its length.
• In a lathe, taper turning means to produce a conical surface by gradual reduction in diameter from a cylindrical work piece.

ii. Straight turning

• The Straight turning produces a cylindrical surface by removing excess metal from the work piece.

iii. Profiling

•  In profiling , the cut can be vary with regard to cutting depth, feed and speed.

iv. External grooving

• In external turning operations machines the outer diameter of the work piece.   

• Facing is an operation of reducing the length of a work piece to produce a flat surface square with the axis.
• A regular turning tool may also be using for facing a large work piece.

• Drilling is an operation of producing a cylindrical hole in a work piece by the rotating cutting edge of a cutter known as the drill .

• Boring is the operation of enlarge a hole or cylindrical cavity to produce circular internal grooves .
• Holes may be bore straight and tapered.

i. Counter Boring

• Counter Boring is the operation of enlarging a hole through a certain distance from one end instead of enlarging the whole drilled surface.

ii. Taper Boring

• Taper Boring is similar to the external taper turning operation and is accomplished by rotating the work on chuck or a face plate, and feeding the tool at an angle to the axis of rotation of the work piece.

• Reaming is the operation of finishing and sizing a hole which has been previously drilled or bored.
• The tool use so call as the reamer , which has multiple cutting edges.

• The operation consists of passing a flat single cut file over the work piece which revolves at high speed.

• Parting is the operation of cutting a work piece after it has been machining to the desired size and shape.
• This process involves rotating the work piece on a chuck or face plate at half the speed that of turning and feeding by a narrow parting – off tool perpendicular to the axis by rotating the cross -slide screw by hand.

• Threading is a operations to produce a helical groove on a cylindrical or conical surface by feeding the tool longitudinally when the job is revolved between center’s or by a chuck.
• Threads can be produced either on internal or external surface of a cylindrical bar.
• Grooving is the process of reducing the diameter of a work piece over a very narrow surface.
• It is often done at the end of a thread or adjacent to a shoulder to leave a small margin.
• Grooving Operations are :

      a. Square Groove

      b. Round Groove

      c. Bevelled Groove

• Forming is the process of turning a convex, concave or of any irregular shape.
• It is basically a surface finishing operation to improve the surface quality of the work piece.
• Polishing with successively finer grades of emery cloth after filling results in very smooth, bright surface.

6 Chapter 2: Lathe Machine

Unit 1: The Engine Lathe

After completing this unit, you should be able to:

• Identify the most important parts of the Lathe and their functions.

• Understand the Lathe safety rules. • Describe setup a cutting tool for machining.

• Describe mount workpiece in the lathe.

• Explain how to install cutting tool.

• Describe the positioning the tool.

• Describe how to centering the workpiece and tailstock center.

Description

The lathe is a very versatile and important machine to know how to operate. This machine rotates a cylindrical object against a tool that the individual controls. The lathe is the forerunner of all machine tools. The work is held and rotated on its axis while the cutting tool is advanced along the line of a desired cut. The lathe is one of the most versatile machine tools used in industry. With suitable attachments, the lather may be used for turning, tapering, form turning, screw cutting, facing, dulling, boring, spinning, grinding, polishing operation. Cutting operations are performed with a cutting tool fed either parallel or at right angles to the axis of the work. The cutting tool may also be fed at an angle, relative to the axis of the work, for machining taper and angles. On a lathe, the tailstock does not rotate. Instead, the spindle that holds the stock rotates. Collets, centers, three jaw chucks, and other work-holding attachments can all be held in spindle. The tailstock can hold tools for drilling, threading, reaming, or cutting tapers. Additionally, it can support the end of the workpiece using a center and can be adjusted to adapt to different workpiece lengths.

Lathe Safety

As always we should be aware of safety requirements and attempt to observe safety rules in order to eliminate serious injury to ourselves or others.

Wear glasses, short sleeves, no tie, no rings, no trying to stop the work by hand. Stop the machine before trying to check the work. Don’t know how it works? –“Don’t run it.” Don’t use rags when the machine is running.

1. Remove the chuck key from the chuck immediately after use. Do not turn the lathe on if the chuck is still in the chuck key.

2. Turn the chuck or faceplate through by hand unless there are binding or clearance issues.

3. It is important that the chuck or faceplate is securely tightened onto the lathe’s spindle.

4. Move the tool bit to a safe distance from the chuck, collet, or face plate when inserting or removing your part.

5. Place the tool post holder to the left of the compound slide. This will ensure that the compound slide will not run into the spindle or chuck attachments.

6. When installing and removing chucks, face plates, and centers, always be sure all mating surfaces are clean and free from burrs.

7. Make sure the tool bit is sharp and has correct clearance angles.

8. Clamp the tool bit as short as possible in the tool holder to prevent it from vibrating or breaking.

9. Evenly apply and maintain cutting fluids. This will prevent morphing.

10. Do not run a threaded spindle in reverse.

11. Never run the machine faster than the recommended speed for the specific material.

12. If a chuck or faceplate is jammed on the spindle nose, contact an instructor to remove it.

13. If any filing is done on work revolving in the lathe, file left handed to prevent slipping into the chuck.

14. Always stop the machine before taking measurements.

15. Stop the machine when removing long stringy chips. Remove them with a pair of pliers.

16. Make sure that the tailstock is locked in place and that the proper adjustments are made if the work is being turned between centers.

17. When turning between centers, avoid cutting completely through the piece.

18. Do not use rags while the machine is running.

19. Remove tools from the tool post and tailstock before cleaning.

20. Do not use compressed air to clean the lathe.

21. Use care when cleaning the lathe. The cutting tools are sharp, the chips are sharp, and the workpiece may be sharp.

22. Make sure the machine is turned off and clean before leaving the workspace. Always remove the chuck wrench after use, avoid horseplay, keep floor area clean. Use care when cleaning the lathe, the cutting tools are sharp, the chips are sharp, and the workpiece may be sharp.

Here are some questions which are important when running a lathe:

• Why is proper Cutting Speed important?

When set too high the tool breaks down quickly, time is lost replacing or reconditioning the tool. Too low of a CS results in low production.

• Depth of cut for Roughing.

• Depth of cut for Finishing.

Notice the largest roughing cuts range from .010 to .030 depending on the material being machined, and .002 to .012 for the finish feed for the different materials.

• Feedrate for Roughing cut

• Feedrate for Finishing cut

Notice the Feedrate for roughing cuts range from .005 to .020 depending on the material being machined, and .002 to .004 for the finish feed for the different materials.

Cutting Tool Terminology

There are many different tools that can be used for turning, facing, and parting operations on the lathe. Each tool is usually composed of carbide as a base material, but can include other compounds. This section covers the different appearances and uses of lathe cutting tools.

To setup a Cutting Tool for Machining

• Move the toolpost to the left-hand side of the compound rest.

• Mount a toolholder in the toolpost so that the set screw in the toolholder is about 1 inch beyond the toolpost.

• Insert the proper cutting tool into the toolholder, having the tool extend .500 inch beyond the toolholder.

• Set the cutting tool point to center height. Check it with straight rule or tailstock.

• Tighten the toolpost securely to prevent it from moving during a cut

Figure 2: Toolpost and Toolholder

To Mount Workpiece in Lathe

• Check that the line center is running true. If it is not running true, remove the center, clean all surfaces, and replace the center. Check again for trueness.

• Clean the lathe center points and the center holes in the workpiece.

• Adjust the tailstock spindle until it projects about 3 inch beyond tailstock.

• Loosen the tailstock clamp nut or lever.

• Place the end of the workpiece in the chuck and slide the tailstock up until it supports the other end of the workpiece.

• Tighten the tailstock clamp nut or level.

Figure 3: Workpiece in Lathe  

Installing a Cutting Tool

• Tool holders are used to hold lathe cutting tools.

• To install, clean the holder and tighten the bolts.

• The lathe’s tool holder is attached to the tool post using a quick release lever.

• The tool post is attached to the machine with a T-bolt.

Figure 4: Installing a Cutting Tool

Positioning the Tool

To reposition the cutting tool, move the cross slide and lathe saddle by hand. Power feeds are also available. Exact procedures are dependent on the machine. The compound provides a third axis of motion, and its angle can be altered to cut tapers at any angle.

1. Loosen the bolts that keep the compound attached to the saddle.

2. Swivel the compound to the correct angle, using the dial indicator located at the compound’s base.

3. Tighten the bolts again.

4. The cutter can be hand fed along the chosen angle. The compound does not have a power feed.

5. If needed, use two hands for a smoother feed rate. This will make a fine finish.

6. Both the compound and cross slide have micrometer dials, but the saddle lacks one.

7. If more accuracy is needed when positioning the saddle, use a dial indicator that is attached to the saddle. Dial indicators press against stops.

Parts of a Lathe Machine and How They Work [Full Guide]

Last Updated on February 7, 2023 by Charles Wilson

Almost every shop with machining operations has a lathe machine.

This POWERFUL tool is used for cutting, turning, forming, spinning, passivation, and other related purposes.

If you’re a beginner or haven’t encountered this cutting tool before, it might be a little confusing with all the main components.

Hence, before laying your hands on it, familiarizing yourself with the different parts of a lathe machine and its functions should be your first assignment.

In this article, I will share with you the things I know about lathe operation, its main components, and the distinct parts of lathe machines depending on your tool.

Key Takeaways:

• A lathe machine is used to rotate workpieces (wood and metal) to perform various operations , including cutting, facing, knurling, and deformation.
• Common operations in a lathe machine involve metal spinning , woodturning , metalworking , thermal spraying , forming screw threads, and creating cylindrical, circular, and flat surfaces.
• Lathe machines have distinct parts from each other depending on the type. But you’re likely to encounter 11 common components .
• Metal lathes can handle BOTH metal and wood workpieces. But, wood lathes can only be used for wood stocks.
• CNC lathes are the most modern lathes . But, the operator must be a trained professional due to its complexity.

Table of Contents

What Are the Different Parts of a Lathe Machine?

There are several parts in a lathe machine. It consists of main components that are similar to all types of lathe machines.

But, it also has parts depending on its specific use.

At first, I also struggled with getting around this machine tool. But I guarantee that studying it is NOT as hard as it sounds!

The lathe bed is the base of the machine tool .

It’s usually a cast iron structure that houses other major parts , including the headstock, spindle, tool post, tailstock, and the like.

This component is supported on broad-box columns. Its upper exterior plane can either be scraped or grounded to provide the guiding and sliding surfaces.

The size and length of the lathe bed likely indicate the MAXIMUM length of the workpiece you can process in one machining operation.

The headstock of the lathe machine is found on the left part of the bed.

It is labeled as the POWERHOUSE of the lathe and holds several drive components , like the spindle motor, gearbox, belt drive, and other holding devices.

It also houses accessories like the three-jaw chuck, faceplate, and lathe dog.

The headstock is the component where the gear speed control levers or feed controllers are mounted.

In CNC lathe machines, the headstock is upgraded by installing a bar feeder for AUTOMATIC feed functions and continuous lathe machine operations.

This all-metal structure provides strength to the machine tool , enabling it to resist strong vibrations during a machining operation.

It also supports the main spindle and aligns it properly. Plus, it holds the necessary transmission mechanism with speed-changing levers for multiple speeds.

On the other hand, the tailstock is found on the opposite side of the headstock.

One of its basic functions includes providing support on the other end of the workpiece during lathe operations.

It’s also essential in holding the tools when performing a drilling operation, reaming operation, turning operation, knurling operation, and other operations in the machine.

You can find the dead centers, adjusting screws, and hand wheel on the tailstock. Its body is also adjustable on the base, which mounts the guideways.

Between the headstocks and tailstock, you’ll be able to locate the carriage. This component guides, supports, and feeds the workpiece during various operations.

This is configured with the feed rod and houses a hand wheel to control its movement parallel to the spindle axis (Z-axis).

Apart from this, the carriage is also the part where other parts are mounted , which include:

• Compound rest
• Cross slide

The saddle is the small H-shaped part on top of the carriage that holds the tool post . It also supports other components, like the compound rest & cross slide.

Cross Slide

The cross slide is attached to the saddle with a female and male dovetail.

Its top surface consists of T slots, which fix the coolant attachments and rear tool post.

The cross slide provides lateral movement to the cutting tool along the X-axis, which determines the cut’s depth during the machining operation.

Compound Rest

The compound rest sits on top of the cross slide, and above it is the compound slide. It supports the tool post and cutting tool to be in various positions .

This is necessary for turning angles during a turning operation and in boring short tapers and forms in a taper turning operation.

It enables these cutting tools to perform ANGLED OPERATIONS, like chamfering and taper turning.

However, you must remember to set it at a desired shape or angle before continuing with the cutting process.

The tool post is where you can find the cutting tool holder for various cutting tools . This part allows the tilting tool to adjust the cutting edge’s height.

The tool holder is mounted on the cross slide. Hence, you can move it along the longitudinal or lateral axis of the lathe machine.

The combined movement, on the other hand, allows you to achieve the desired machining operation .

You can configure the tool post on a metal lathe machine into four different settings: single screw, open side, four bolt, and four-way.

Gang tool lathes, on the other hand, have special tool posts to hold multiple cutting tools for a distinct machining process.

The apron is coupled with the feed rod on the carriage for automatic movement . It’s also fastened with the saddle, hanging over the front of the bed.

This component has gears and clutches, which transmit motion from the feed rod to the carriage.

Additionally, it houses the split nut that engages with the lead screw when cutting threads.

Another major component among lathe machine parts is the lead screw — a long driveshaft with acme threads.

This is usually used during a thread-cutting operation and finish taper-turning operations .

It facilitates longitudinal movement to move the carriage automatically and is used to set automatic feed.

Threading operations involve a rotating workpiece plus the linear movement of the tool. Such a rotation is achieved through the chuck, while the lead screw provides linear movement .

This rod is a power transmission mechanism that enables the carriage’s precise linear movement along with the lathe machine’s longitudinal axis.

Other lathe machine tools use lead screws instead of feed rods.

The chip pan is the metal tray at the bottom of the lathe machine. Its main purpose is collecting the chips produced during the machining process .

With the chip pan, you’ll minimize the hassle of collecting chips scattered on the shop floor.

Hand wheels are essential in positioning the parts of the lathe machine at the desired angle. Each component has a dedicated hand wheel that you can rotate.

An ordinary lathe machine may contain up to three hand wheels, which control the carriage, tailstock, and cutting tool.

The chuck is a work-holding device utilized in mounting workpieces having distinct diameters.

It particularly holds those with a short length and large diameter and those with irregular shapes.

The commonly used types of chuck are as follows:

• Three-jaw or four-jaw chuck
• Collet chuck
• Magnetic chuck

But for a CNC lathe, a hydraulic chuck is used. Compared to manual chucks, this is easier to align, as it clamps the workpiece AUTOMATICALLY.

Main Spindle

The lathe spindle is the rotary component of the machine tool .

The rotating motion produced by the electric motor is passed on to the spindle, causing the chuck and workpiece to rotate alongside it.

A typical lathe machine has one spindle to do the job. But, others may have multiple spindles to enhance productivity.

Cooling System

This component is particular among metal lathe machines because metal workpieces generate frictional heat . Hence, a cooling system is needed to PREVENT damage.

The system has a tank that stores the cutting fluid and pumps it to the machining area towards the cutting area.

It lubricates and cools the medium by removing the heat from the point of contact.

Diagram of a Lathe Machine

I won’t stop at knowing a lathe machine’s main function and parts. You also need to visualize the machine and see each component’s location.

I inserted a lathe diagram in this section, illustrating the parts of the machine tool. The photo above will show you the main parts mounted in the lathe machine:

Different Types of Lathe Machines

There are different types of lathe machines that are specific to their purpose and performance. These are as follows:

• Speed lathe machine
• Center lathe or engine lathe machine
• Capstan and turret lathe machine
• Toolroom lathe machine
• Bench lathe machine
• Automatic lathe machine
• Special-purpose lathe machine
• CNC lathe machine

In the next section, I’ll provide brief descriptions of the 8 types of lathe machines, plus metal and wood lathes, so you’ll know which machine to use.

Speed Lathe

A speed lathe is a hand-operated machine used by woodworkers. It provides a HIGH spindle speed from 1200 to 3600 rpm.

This type uses a light force and lesser depth in the cut compared to other lathe machine tools.

This tool is commonly used for woodturning, metal spinning, centering, and polishing.

Center Lathe or Engine Lathe

The center or engine lathe is the most popular among the other types and is used for metal or woodworking .

It’s commonly utilized as a turning, grooving, facing, thread-cutting, and knurling tool . 

If you’re looking for a machine that handles pieces up to 1 meter in diameter, this lathe is the one I recommend.

Capstan Lathe and Turret Lathe

A capstan lathe and turret lathe are used for mass production . I can describe it as the older brother of an engine lathe because it is more UPGRADED.

The tailstock on this tool is replaced with hexagonal turret heads, and it’s mounted with THREE instead of one tool holder.

You can also install different tools in this machine, may it be for a drilling operation, knurling operation, or other purposes.

Hence, you can perform MULTIPLE tasks in a short time.

Tool Room Lathe

This is the machine you’ll most likely encounter if your projects involve making precision parts , including gauges, jigs, and fixtures.

A tool room works at multiple speeds, from the lowest to a quite higher 2500 rpm.

Bench Lathe

A bench lathe is used for very small precision projects . Jewelers and watchmakers are the ones who commonly use this tool.

It performs similar tasks as an engine lathe and consists of similar parts.

Automatic Lathe

An automatic lathe is a machine capable of automatically feeding cutting tools due to its mechanisms.

It can control 5 to 6 lathes at a time, and it performs quickly and does really well in heavy-duty production.

Special-Purpose Lathe

Special-purpose lathes are custom-made to perform specific tasks and production work. These are commonly utilized in heavy-duty projects regular lathes can’t perform.

Examples of these are:

• Hydraulic quill

Metal Lathe

A metal lathe is used in machining hard metal workpieces like iron and steel. Yet, you can also use it to process wood.

As you noticed, the types of lathes I specified in the previous sections support both mediums.

By using this, you can deform a workpiece to achieve your desired shape.

A CNC lathe is the most updated type of lathe machine discussed in this article. CNC machines are integrated with modern computer numeric control systems (CNC).

These systems allow users to add a CAD/CAM program to command the machine . In turn, the CNC lathe automatically operates according to the input.

CNC lathes are SPEEDY and more HEAVY-DUTY. Its accuracy and precision are also better compared to manually-operated machines.

Mass production with a CNC lathe is cheaper and relatively faster, too.

But, CNC lathes are costly .

You may need to shell out lots of cash for CNC lathes’ power consumption and routine maintenance, plus you must hire a professional to operate this.

NOTE: CNC lathes are more complex than other machines. No one should operate CNC lathes without proper training and skill.

Wood lathes can only work with wood-based workpieces . It’s mainly used to cut, drill, sand, face, and deform such materials.

You can move the tool against the workpiece to remove material and achieve your intended shape and size.

Frequently Asked Questions

Let’s go through some common questions you might have in mind:

Can You Use CNC Lathe on Wood?

ABSOLUTELY! You can use both metal and wood workpieces in CNC lathes.

However, if the wood stock is oddly irregular in structure, I suggest you use hand-held machines, which can handle vibrations better than a CNC lathe.

What Are Important Terms to Know in Using a Lathe Machine?

SOB and DBC are important terms to remember when using a lathe.

SOB (Swing Over Bed)

SOB refers to the maximum workpiece diameter a machine can handle. Generally, this is twice the distance between the bed and the center of the spindle.

DBC (Distance Between Centers)

DBC, on the other hand, refers to the distance between the headstock and tailstock .

This is equal to the bed’s length, which determines the maximum workpiece length you can turn on the machine.

There are different parts of the lathe you MUST familiarize yourself with before getting your hands on one.

It may be confusing at first, but I guarantee you’ll get the hang of it in the long run.

I experienced the same dilemma as you when I was only a beginner. Yet, enduring the painful process of learning the basics is totally WORTH IT.

I hope this guide was able to help you in your lathe learning journey!

In this article, I will explain in detail everything about Lathe Machines . We have also provided a PDF download link for the same

What is the History of Lathe Machine?

Lathe machine is known as the mother of all machines in the production sector. The metal lathes found their origination in the ancient Egyptian civilization while the modern metal lathe machines were first developed during the 18th century industrial revolution. The earlier lathe were hand or foot operated then transitioned to being steam operated to provide certain level of automation.

Further developments in the 19th century made these lathe machines more precise and versatile making them capable to produce complex parts. Shortly after the invention of electric motors they were introduced for lathe machines which lead to their wide application in the manufacturing sector. Today in the modern Era of 20th century the development of computer numerically controlled or CNC lathe machines have revolutionized the production sectors offering the highest precision and automation features.

Lathe Machine 3D Model

What is the definition of lathe machine.

A Lathe Machine offers versatility which can be useful to shape and cut materials like metal, plastics, and wood. A lathe machine is a tool where the workpiece is rotated on its axis which allows the cutting tool to perform material removal operations on the workpiece and create desired shape. Lathe machines can be operated manually or using CNC technology. These Lathe machines are available in different sizes for different applications

They are vastly used in machining industries or manufacturing sectors for creating parts with precise dimensions and complex figures. The lathe machines of various parts like headstock, tailstock, bed, tool post, carriage, etc., and the types of lathe machines include turret lathes , engine lathes, wood lathes, and vertical lathes each with specific advantages and features.

Lathe Machine Parts & Function

Lathe machine consists of the below given common parts which are as follows

Cross-slide

Compound rest.

• Main spindle

All of these parts are explained in detail below.

The main foundation of the lathe machine is the lathe bed that supports the different parts of the machine like headstock, carriage, and tailstock. The lathe made is made up of steel or cast iron and have different shape and size depending on the application intended

The Lathe Bed has a long, rectangular-shaped structure bolted to the workbench. It serves to provide a stable and rigid platform for the movement of workpieces and cutting tools during machining operations. It is defined to be mostly flat and leveled to make sure the movement of cutting tools is always in straight line to obtain precise and accurate results.

The cutting tool is held by the carriage and performs movement along the length of the lathe bed guided by rails or a set of ways that are machined in the surface of the bed. Near the Headstock the tailstock is also mounted on the lathe bed which supports the opposite end of the workpiece. The lathe bed is designed to provide accuracy and stability during machining operations. They have a robust construction to be long lasting, durable, and withstand constant stresses and vibration produced during machining processes

The Lathe headstock is a vital part of the Lathe machine, rotating and supporting the workpiece during machining. It includes components like spindle, pulleys, motor, and bearings, typically positioned on the left side of the lathe bed.

The main functions of the lathe headstock are:

• Rotation of the workpiece: The workpiece is rotated by the spindle of the headstock at different speed which allow the cutting tool to give desired shapes.
• Support of the workpiece: The workpiece is supported by the bearing in the headstock to ensure that during any machining operation the workpiece remains stable for maximum precision.
• Transmission of power: The spindle is driven by the headstock motor with the help of various belts and pulley arrangements so that there is ample power transmitted to turn the workpiece.
• Provision of threading capabilities: In some lathes, the headstock can be used to cut threads on the workpiece using specialized attachments.
• Alignment of the workpiece: The headstock ensures that the workpiece is accurately aligned with the tailstock and other machining components of the lathe, allowing for precise machining operations.

Accessories mounted on headstock spindle :

• Three jaw chuck
• Four jaw chuck
• Lathe center and lathe dog
• Collect chuck
• Magnetic chuck

The tail stock is situated on the right side above the lathe bed.

It is used for the following:

• Support the long end of the job for holding and minimizes its sagging.
• It holds the tool for performing different operations like drilling, reaming, tapping, etc.
• And it is also used for a small amount of taper for a long job by offsetting the tailstock.

The carriage is used to support, guide, and feed the tool against the job when the machining is done.

• It holds moves and controls the cutting tool.
• It gives rigid support to the tool during operations.
• It transfers power from the feed rod to the cutting tool through the apron mechanism for longitudinal cross-feeding.
• It simplifies the thread-cutting operation with the help of a lead screw and a half-nut mechanism.

Carriage consists of the following:

It provides three movements to the tool:

• Longitudinal feed-through carriage movement
• Cross feed-through  cross slide movement
• Angular feed-through top slide movement

Saddle , it is made up of ‘H’ shaped casting and it has a ‘V’ guide and a flat guide for mounting it on the lathe bed guideways.

Cross-Slide is assembled on the top of the saddle. The top surface of the cross-slide is provided with T-slot.

Compound Rest supports the tool post and cutting tool in its various positions. It can be swiveled at any desired position in the horizontal plane. It is necessary for turning angles and boring short tapers.

Tool Post is the topmost portion of the carriage and it is used to hold various cutting tools or tool holders.

There are three types of tool posts commonly used and those are:

• Ring and rocker tool post
• Square head tool post
• Quick change tool post

An apron is a house of the feed mechanism. It is fastened to the saddle and hangover in front of the bed.

A Lead Screw is also known as a power screw or a translation screw. It converts rotational motion to linear motion. Lead Screw is used for Thread Cutting operation in a lathe machine tool.

The Feed Rod is used to move the carriage from the left side to the right side and also from the right side to the left side.

Chuck is used to holding the workpiece securely.

There are generally 2 types of chucks:

• 3 jaw self-centering chuck
• 4 jaw independent chuck

Main Spindle

The spindle is a hollow cylindrical shaft through which long jobs can pass through it. It is designed so well that the thrust of the cutting tool does not deflect the spindle.

Legs are carrying an entire load of a lathe machine tool and transfer to the ground. The legs are firmly secured to the floor by the foundation bolt.

What are the Types of Lathe Machine?

A lathe machine tool is used for removing the excess material from the workpiece to give the required shape and size to the workpiece.

So how many types of Lathe machines are there? Lathe machine has been categorized into the following types:

• Center or Engine Lathe

Speed Lathe

Capstan and turret lathe, tool room lathe, bench lathe, automatic lathe.

• Special Purpose and

CNC Lathe Machine

We are going to study each and every important point of these 8 different types of lathe machines.

Center or Engine Lathe Machine

Center or Engine Lathe Machine is the most widely used lathe machine and still, it is, in every workshop, this machine is present. Operations like Turning, facing, grooving, Knurling, threading, and more, such operations are performed on this type of machine. The engine lathe machine has all the parts such as bed, Saddle, headstock, tailstock, etc. The headstock of an engine lathe is rigid and the tailstock is moveable which is further used to support an operation like knurling.

It can easily feed the cutting tool in both directions i.e. longitudinal and lateral directions with the help of feed mechanisms. Center Lathe machine s are driven by the gear mechanism or pulley mechanism. It has three types of driven mechanisms, and those are Belt-driven, Motor-driven, and Gearhead type .

A speed lathe is also called a Wood Lathe . As the name indicates “Speed” the machine works at high speed. The headstock spindle is rotating at a very high speed. The parts have headstock and tailstock, but it does not have feed mechanisms like a center or engine lathe. The feed we provide is manually operated. The speed ranges of this machine operated between 1200 to 3600 RPM. The speed lathe is used for metal spinning, centering, polishing, and machining wood.

This is an advanced technology in the manufacturing industry. The capstan and turret lathe machine is used for Mass production (large Quantity) and is a modified version of the engine lathe machine . This machine is used where their sequence of operation is performed on the workpiece, there is no alternative operation performed on this machine.

These machines were provided by a hexagonal turret head instead of the tailstock in which multiple operations (Turning, facing, boring, reaming) were performed in a sequence without changing its tool manually, after each operation the turret rotated. It also consists of three tool posts. It requires more floor space than other lathe machines.

Capstan and turret lathe is used for only large jobs. The main advantage of using a capstan and turret lathe is even less skilled operators can do a job.

The tool room lathe machine operates to speed up to 2500 rpm. The parts are almost the same similar to the engine lathe machines but the parts are built very accurately and should be arranged in proper sequence because this lathe is used for highly precious work with very fewer tolerances. It is mainly used in grindings, working on the tool, die gauges, and machining work where accuracy is needed.

Bench lathe machines are mounted on the bench. This type of lathe machine is small in size and use for very small precision work. It has all the similar parts to the engine lathe and speed lathe.

As the name indicates “Automatic lathe” performs work automatically. Standard lathes have some drawbacks i.e. they are not used for mass production. But automatic lathes are used for mass production. Some mechanisms are responsible for its automation in it. Here there is no need to change the tool manually because it changes automatically. Having this machine the main advantage is that a single operator can handle machines more than 4 to 5 machines at a time. These types of lathes are high-speed and heavy-duty.

Special Purpose Lathe

As the name indicates “special purpose lathe” the machine performs special types of operations which can not be performed on standard and other machines. It is known for the heavy-duty production of identical parts. Some examples of special lathes include Vertical lathes, Wheel lathes, T-lathe, Multi Spindle lathes, Production lathes, Duplicate or tracer lathes , etc.

The wheel lathe is used for machining journals and rail rods. It is also used for turning the threads on locomotive wheels. The “T -lathe” is used for machining rotors for jet engines . The axis of the lathe bed is at right angle to the axis of the headstock spindle in the form of a T.

CNC stands for Computerized numerically controlled . This is widely used as a lathe in the present time because of its fast and accurate working. It is one of the most advanced types. CNC Lathe uses computer programs to control the machine tool. Once the program is fed into the computer as per the program it starts operation with very high speed and accuracy.

Even do preplanned programmed machine is there in which once code is set for the various operations it can start operation without changing the code the next time. A semi-skilled worker can easily operate this after the initial setup is done. These types of lathes are also used for mass production like capstan and turret but there is no programmed fed system. The components manufactured by these lathes are very accurate in dimensional tolerances.

How are operations performed During Lathe machining?

A Lathe Machine consists of the following operation:

• Thread cutting
• Parting off

In Lathe operation, the workpiece is mounted on the spindle and rotated at the desired speed. To create the shape we need to remove material by moving it along the length by making it come in contact with the workpiece. The carriage is moved along the bed to control the depth of the cut, and the cutting tool can be changed as required to perform different machining operations. Before continuing any operation in the lathe we have to load the job and center it on the head-stock spindle.

Centering operation in the lathe

We use this operation for producing a conical hole in the face of the job to make the bearing support of the lathe center when the job is to hold between two centers. (Head-stock and Tail-stock).

Facing operation in the lathe

Facing operation is for making the ends of the job produce a smooth flat surface with the axis of operation or a certain length of a job.

In this operation,

• Hold the job on the Head-stock spindle using a Three or four-jaw chuck.
• Start the machine on the desired RPM to rotate the job.
• Give a desirable feed on the perpendicular direction of the axis of the job.

Turning operation in the lathe

The operation by which we remove the excess material from the workpiece to produce a cone-shaped or cylindrical surface.

There are several types of turning operations, those are:

Straight turning

Shoulder turning, rough turning, finish turning, taper turning.

• Eccentric turning

To produce a cylindrical surface by removing excess material from a workpiece we employ the straight turning operation which is performed in the following way

• Mount the job with a suitable job-holding device and check the trueness of the job axis with the lathe axis.
• Hold the cutting tool on the tool post and set the cutting edge at the job axis or slightly above it.
• Set the spindle as per the desired feed.
• Give depth of cut as per finish or rough cut.
• Start the machining.
• Engage the automatic feed to move the carriage with the tool to the desired length, then disengage the feed, and the carriage is brought back to its starting.
• The process goes on until the job is finished.

A shoulder turning is called which has a different diameter to form a step from one diameter to another.

There are four kinds of shoulder.

It is a process of removal of excess material from the workpiece in minimum time by applying a high rate of feed and heavy depth of cut. the depth of cut is around 2 to 5mm and the rate of feed is 0.3 to 1.5mm/revolution.

The finish turning operation needs high cutting speed, minimum feed, and a very small depth of cut to generate a smooth surface. In finish turning the depth of cut is around 0.5 to 1mm and the rate of feed is 0.1 to 0.3 mm/revolution.

A taper is defined as a uniform decrease or increase in the diameter of a workpiece along with its length. The operation by which a conical surface of the gradual reduction in diameter from a cylindrical workpiece is produced is called taper turning .

Taper turning methods

A tapering form may be done by any one of the following methods.

Taper turning by form tool

• By swiveling the compound rest
• Tail-stock set over method
• By taper-turning attachment

Let me discuss them in brief.

It is used to form a short length of taper by using a form tool or broad nose tool. Any increase in the length of the taper will require the use of a wider cutting edge which may destroy the workpiece due to the vibration and spoil the workpiece.

In this operation, the tool angle must be half of the taper angle.

Taper turning by swiveling the compound rest

This method is used for turning steps and short tapers. It is done as follows:

• Set the compound rest by swiveling it from the centerline of the lathe center through an angle equal to a half-taper angle.
• Clamp the carriage in place.
• After adjusting and setting the tool, feed is applied by the compound rest’s feed handle to complete the taper.

Tail-stock set-over method

Set over of tail-stock from its center-line is done equal to half taper. Job is held between the centers. The length of the workpiece will be long enough. Only a small taper on a long job is done by this process. It is used for external taper only.

By taper turning attachment

It is done in the following ways:

• The cross slide is first made free from the lead screw by a hinder screw.
• The rear end of the cross slide is then tightened with a guide block by a belt.
• Set the guide bar at an angle to the lathe axis. (Half taper angle)
• The required depth of cut is given by the compound slide at a right angle to the lathe axis.

Chamfering operation

Chamfering is used for beveling the end of a job to remove burrs, to look better, and to make a passage of the nut into the bolt. This operation is done after thread cutting, knurling, and rough turning.

Knurling operation

It is the process of producing a rough surface on the workpiece to provide effective gripping. The knurling tool is held rigidly on the tool post and pressed against the rotating job leaving the exact facsimile of the tool on the surface of the job.

Thread-cutting operation

It is the operation that is used to produce a helical groove on a cylindrical or conical surface by feeding the tool longitudinally when the job revolved between the two centers.

Tool setting for thread-cutting operation

The tool should be set exactly to the height of the centerline of the job and at 90 degrees to the job. A tool setting gauge is used for this purpose.

Feeding during thread-cutting operation

It is done in two ways.

• The tool may be fed exactly at 90 degrees to the job axis but it does not have good cutting action because only the front end of the tool does cutting.
• The tool may be fed at an angle from 27-30 degrees at which the compound rest may be set so that the complete side of the tool is used for cutting action which gives a better polish on the threads.

Job speed during threading

The job speed will be 1/3 to 1/4th of the job speed in turning operation.

Drilling operation

Drilling is an operation by which we can make holes in a job. In this operation, the job is rotated at the turning speed on the lathe axis and the drilling tool is fitted on the tail-stock spindle. And the tailstock is moved towards the job by hand feed.

Boring operation

In this operation, we can enlarge the diameter of the existing hole on a job by turning it inside with some farm tool known as a boring tool . The boring tool is also fitted on the tailstock.

Reaming operation

Reaming is the operation of sizing or finishing a drilled hole to the required size by a tool called a reamer. This tool is fitted on the tailstock.

Spinning operation

In this operation, the job of this sheet metal is held between the former and the tail-stock center and rotates at high speed with the former. The long round nose forming tool rigidly fixed on a special tool post presses the job on the periphery of the former. So the job is taken exactly the shape of the former.

Spinning Operation is a chip less machining process.

Tapping operation

We use this operation for creating internal threads within a hole by means of a tool called tap .

Three taps are generally used in an internal thread.

Parting-off operation

It is the operation of cutting off a bar-type job after completing the machining process. In this operation, a bar-type job is held on a chuck, rotates at turning speed, and a parting-off tool is fed into the job slowly until the tool reaches the center of the job.

Specification of a Lathe

A Lathe is generally specified by the following

• Swing is the largest work diameter that can be swung for the lathe bed.
• The distance between the headstock and tailstock center.
• Length of the bed in a meter.
• The pitch of the lead screw.
• Horsepower of the machine.
• Speed range and the number of speeds of HS spindle.
• The weight of the machine is around a ton.

Basic Lathe Operations | Lathe operation Explained

Lathe is a machine tool which causes workpiece to revolve so that when cutting tool comes in contact with the workpiece it removes the metal in the form of  chips. Workpiece can be held securely and rigidly on the machine tool between centres or by means of chuck. To cut the material easily the cutting tool should be harder than the material of workpiece. It should be rigidly held on the machine or  should be fed in a definite way relative to the workpiece.

Arrangements for setting the direction of tool advancement and its rigid holding, are already provided on lathe machine.

LATHE OPERATIONS

A standard machine is that which is able to deal with a variety of work and a wide range of operations can be performed on it. Special purpose machine is that which has been designed for specific purpose and only performs one or limited range of  operations.

A centre lathe is an example of standard lathe because on this machine we can perform the following operations :

(a) Turning (b) Facing (c) Parting off (d) Knurling (e) Thread cutting (f) Grooving (g) Drilling (h) Boring (i) Reaming

These operations are described below in detail.

It is the removal of material from the outside diameter of a cylindrical job to obtain one or more finished diameter. Usually, there are three types of  turning which are given below :

(a) Plain or straight or parallel turning. (b) Stepped turning. (c) Taper turning.

In plain turning machining is done in this way that after removal of  material, finished diameter at both the ends of length remains equal. Turning operation where the entire length is divided in steps of different diameter but each step individually finished by using plain turning is known as stepped turning. Taper turning is the operation in which the material is removed from the job to produce a conical shape. All the three types of  turning are shown in Figure 7.13.

Plain Turning and Stepped Turning

In plain turning, the workpiece is turned straight throughout the entire length when it is made to rotate about the lathe axis, and the cutting tool is fed along the lathe axis. The plain or straight turning produces a cylindrical surface after machining.

In stepped turning, the workpiece is turned in such a way that throughout the turning length it forms the steps of different diameters. After facing and centering at both ends faces, the job is mounted between the centres using a dog carrier attached to the workpiece, the bent tail of  dog carrier is fitted into the slot provided on the driven plate. If the workpiece is mounted on a chuck, care should be taken to centre it accurately with the lathe axis. The trueness of the workpiece held on a chuck is tested by holding a scriber or a dial indicator against the rotating workpiece. Turning tool is clamped on the tool post by keeping its cutting edge approximately at the lathe axis or slightly above it.

Taper Turning

Generally, the following methods are used for taper turning : (a) By swivelling compound rest (b) By setting over the tail stock (c) By taper turning attachment (d) By forming or broad-nose tool By Swivelling Compound Rest

This method is used to produce short or steep tapers. The principle of  this compound rest is that axis of workpiece rotates parallel to the bed axis and the cutting tool moves at the desired angle where the compound rest is already swivelled.

Let the swivelled angle of compound rest with lathe axis is ‘θ’. ‘ L’ shows the length, on which taper turning takes place. We can calculate the swivelled angle of compound rest in respect of lathe axis

by following formula : tan θ = ( D – d) / L

where ‘ D’ and ‘d ’ are the larger and smaller diameters respectively.

It is the machining of the ends of a workpiece to make the ends smooth. For  this operation, the cutting tool is fed perpendicular to the lathe or workpiece axis by means of cross slide.

Parting Off

This operation involves cutting the work-metal into two parts by using parting off tool. Feed to the cutting tool is given in same manner as in case of facing operation.

It is the process of producing rough surface of embossing diamond shaped pattern on a smooth surface of a cylindrical job. Knurling provides an effective gripping surface on a job to prevent it from slipping when operated by hand. Knurling, as shown in Figure 7.14, may be of two types : (a) straight or parallel, and (b) diamond type.

Knurling is done by means of knurling tool which consists of a set of  hardened steel rollers. The teeth are cut on the steel rollers in different pattern. For knurling operation, the knurling tool is forced with the workpiece which is already arranged in revolving condition.

Thread Cutting

In thread cutting operation, there is a certain ratio of motion between the travel of tool and the rotation of the spindle. This ratio is directly effected by the lead screw which is attached to the lathe spindle through gears. General set up for thread cutting is shown in Figure 7.15.

For cutting threads of different pitches, the stud (driver gear) and lead screw gear  (driven gear) are changed as per desired ratio of revolution between the spindle and the lead screw. The ratio between the teeth on stud and lead screw gear can be calculated by the given formula,

This operation is also denoted as necking. Usually, grooves are cut on a cylindrical surface in narrow shape by means of grooving tool. The cutting edge of grooving tool is kept narrow.

For making a standard size of hole in a workpiece by means of drill is known as drilling operation. For this operation, drill is held in tail stock spindle.

Boring is the operation of enlarging a drilled hole by means of a boring tool. The boring tool is fitted on a boring bar which is held in tail stock  spindle.

It is the operation of finishing a drilled hole to an accurate dimension with the help of reamer as a tool. The reamer is held on the tail stock spindle.

When I went to school for machining, I worked on a bunch of different projects that taught me the basics of the trade. From keychains to hammers, I did all the typical stuff.

One thing that I found out after the program, though, is that the chess pieces and keychains were quickly lost, but the tools I made are still in my box and used daily 12 years later. When you’re able to use great tools that you made yourself, it adds a definite element of pride to your work.

I’ve compiled a list of practical projects for up-and-coming machinists to hone their skills. They’re not decorative pieces, like turner’s cubes or random widgets. All of them are tools that you’ll likely use every week, if not every day.

For each one, I’ll go over the BOM, the equipment needed, and give you the drawings. Most of them are ones that I’ve made myself, and some of them are the upgraded versions to make them more useful as tools.

Slide Hammer

If you’re working with pull dowels, which are a common fixturing element in many shops, then you’ll need one of these in your toolbox.

This is a nice and simple project that is great for absolute beginners. It doesn’t take too long to do, but it will give an opportunity to learn the fundamentals of turning.

This tool is exactly what you’ll need to pull 1/2 dowels from tight holes. To make it last longer, there’s a replaceable 1/4-20 set screw that’s used to hold on to the dowel. Mine’s in perfect shape still, aside from a few scuffs and dings, and I use it daily.

Personally, I like making tools out of stainless where possible, since they’ll last longer than I will. If the budget is tight or selection is limited, though, you can just as easily use steel or aluminum.

Here’s the BOM:

• Ø 2.0″ x 4-5/8″ long stainless (1 pc)
• Ø 0.50″ x 12-1/8″ long stainless (1 pc)
• Ø 1.0″ x 5/8″ long stainless (1 pc)
• 1/2″ E-clip (1 pc)
• 1/2-13 x 1″ long socket head set screw (1 pc)

And here are the drawings:

Machinist’s Hammer

I don’t know a single machinist that hasn’t made one of these.

The actual design varies by school, but they all look essentially the same.

I modified the design of the one I made over a decade ago based on things I wasn’t crazy about. For example, this one has flats on the handle. I always found it annoying that with a fully round handle, you couldn’t keep the hammer straight by feel – you had to look at it. Now that’s fixed.

To mill the flats, I wait until the hammer is finished and assembled. Then I stick it in a milling vise, dial in the hammer head, and mill one side and add the chamfer. Then I flip it, using the underside as a register for the second flat and chamfer.

I also drilled a hole in the bottom of the handle. I use it to fit allen keys, so I can use the hammer as a small cheater bar. It’s saved my knuckles a few times. You can make it shallower or deeper to get a hammer balance that suits you.

I adjusted the balance between the head and the handle to something I find more comfortable for the light tapping that this type of hammer is more typically used for. Some people like to have one end brass and one end aluminum, although I prefer two brass inserts – that’s the end I always use anyway. And, since brass is significantly heavier than aluminum, I find that it feels better.

This is a good project to get familiar with taper cutting on the lathe. For cutting the self-holding tapers for the inserts, I usually lock the compound rest at the angle and use a single setup to cut both the male and female tapers. If you get a smooth surface, that taper will hold forever. Either the taper attachment or the offset tailstock method can be used for the handle.

• Ø 1.25″ x 10.125″ long steel (1 pc)
• Ø 1.25″ x 2.125″ long steel (1 pc)
• Ø 1.50″ x 1.25″ long steel (2 pcs)

Here are the drawings:

Toolmaker’s Vise

This one is good for more advanced students. Traditionally, this has been a project for tool and die makers. The skills that are targeted are job planning with grind allowance and order of operations. Machines used are mills, heat treating ovens, grinders, and lathes.

The vise is definitely an involved project, but one that’s well made is a work of art. For an extra challenge, try CNC engraving the name of the student in the vise body prior to heat treat and try to make the letters appear even after grinding.

I strongly prefer to make this out of A2, since it’s stable and air-quenched, which means that the vise will be nice and clean. Some schools choose to use 4140, but it can be pretty demotivating when a student rough machines the part, and then has to do it again because it cracked in the oil quench.

• 2.5″ x 2.5″ x 6.125″ A2 tool steel (1 pc)
• 2.5″ x 2.5″ x 1.4375″ A2 tool steel (1 pc)
• Ø 1″.0 x 1.0625″ long 4140 HTSR (1 pc)
• 3/8-16 x 2.25 SHCS  (1 pc)
• CL-2-SW Spherical Washer  (1 pc)

I went light on this drawing. Lots of schools have it slathered with GD&T. Personally, I love it, since it helps ensure a working part at the end of the day. If you want to add the GD&T requirements on this drawing, you’ll usually find this part covered in perpendicularity and parallelism callouts of 0.0003″everywhere. Use your discretion with what your students can reasonably measure.

Micrometer Stand

This one is actually really uncommon to see as a school project, but it’s definitely a handy tool to have. Whether you’re checking against the standard or trying to measure an awkward little part to 0.0002″, a mic stand is worth having around.

What I like about this project is that it’s actually pretty forgiving, but it looks really nice if you can get good surface finish. Plus I always like how the combination of brass and steel look.

Overall this project will help the beginner learn basic things like slotting on a mill and threading on a lathe. There are lots of non-critical features that are purely cosmetic, but there are a handful that just need to be done right for this thing to work smoothly.

• 1.5″ x 2.5″ x 4.625″ steel (1 pc)
• 0.75″ x 0.75″ x 2.0″ brass (1 pc)
• Ø 0.625″ x 1.875″ long brass (1 pc)
• Ø 1.5″ x 0.75″ long brass (1 pc)
• 1/4-20 x 1″ long set screw (1 pc)

I use the 1/4″ set screw just to simplify the project to allow for tapping the holes. If you tighten up that set screw with a bit of threadlocker it’ll hold more than enough.

Dial Indicator Depth Attachment

A great attachment for making a simple dial indicator even more useful. This is a really good way of checking the depth of shallow steps or seeing how deep a damaged area on a part is.

This is the simpler of the two depth attachments. It’s a very basic project to get familiar with mills and lathes. You’ll get to do some threading on the lathe and learn how to make a clean undercut. You can also use it as an opportunity to grind some HSS cutting tools for threading and undercutting.

The milling portion is very simple. Even the perpendicularity of the hole to the bottom surface of the base isn’t critical enough to really affect the functionality of this tool.

• 1″ x 1″ x 2.125″ mild steel flat bar (1 pc)
• Ø 0.625″ x 0.625″ long brass bar stock (1 pc)
• Dial indicator  (1 pc)

Caliper Depth Attachment

A simple, handly little attachment for your calipers, this will fit Mitutoyo 6 and 8 inch models. It’ll also fit most other brands, but I ain’t making any promises.

This project gives you a bit of experience on both a mill and a lathe. Specific skills to hone are how to maintain perpendicularity, turning and threading small parts, and how to do a bolt circle (although it’s just cosmetic).

What’s nice about this project is that it doesn’t use a lot of material, and it’s 100% home made – no hardware required. 

The project could also be modified to allow for some practice with heat treating and grinding if you want a hardened steel body. You could also learn to polish the brass. Do whatever makes you happy.

Here’s the bill of materials:

• 1.5″ x 0.5″ x 3.125″ mild steel flat bar (1 pc)
• Ø 5/8″ x .625″ long brass round bar (2 pcs)
• Calipers (1 pc)

If you want to harden it and grind it, replace the mild steel with 4140 or A2.

Caliper Center Distance Attachment

This is a really simple little job, but it does require precision. What’s kind of cool about this is that for marking student projects, you can just have a plate drilled with holes in known locations, then compare what you get on the calipers.

Since there’s so little material needed, this is a nice and cheap project for an entire classroom to work on. The bottom of the slot is aligned with the center of the taper, so the idea is that you should be able to keep your calipers set as they are instead of needing to rezero for basic measurements.

This is a really handy attachment for measuring things like bolt circles. The only downside is that the top of the hole needs to be in good condition.

Overall, you get to try out working with a collet on the lathe (ideally) and being able to very accurately aligning and cutting a slot on a shaft. You’ll also get to try tapping some really small 4-40 holes.

• Ø 0.375″ x 1.875″ long TGP stainless round stock (2 pcs)
• 4-40 x 0.125″ long UNC half-dog point set screws (4 pcs)

And here’s the drawing:

These are staple tools that you’ll seriously be using all the time.

This project will hone the skills of job planning, milling, heat treating, and grinding. If you choose to make the clamps using a band saw, there’s also the opportunity to practice layouts and some bench work.

If you’re teaching a course on machining, it might be cool to start on the clamps early on, and then later on make the vee blocks as a separate project. That way the students can be challenged at their skill level for both aspects of the project.

• 2″ x 2″ x 2″ 4140 steel (x2)
• 2.5″ x 2.5″ x 0.5″ mild steel (x2)
• 1/4-20 x 2″ long hex bolt (x2) – make sure to machine a half dog point on the tip so it doesn’t get stuck in the clamp

Edge Clamps

This is a handy little set of clamps to have, especially when you’re working with longer pieces of flat bar or plates.

If you can keep the 1″ thickness accurate then you can also use 123 blocks to support your workpiece.

Here’s how they work: When you loosen them and push them against the workpiece, the jaw is moved off the countersunk hole centerline. When you tighten them, the flat head screw tries to force the jaw back into alignment to it can properly seat. The result is clamping force.

I’d recommend making them in sets of 6. This can be a great little CNC job, since there are a couple of them to run.

This project is good for people wanting to learn things like slotting on a mill, drilling, tapping and countersinking. The jaws and body are heat treated and ground.

This also exposes you to more creative ways of workholding; not everything needs to be done in a milling vise. You can flip them around to accommodate different operations and parts.

If you want to have some clearance under the part for drilling through, try putting the clamps on a 45-degree angle so only a small part of the base is supporting the part. For thicker workpieces, they can be used very similarly to a standard toe clamp.

For more bite, you can tilt the jaws at an angle in a vise and use an endmill to machine teeth on one side.

Ultimately, aside from being good practice for a few milling and grinding operations, having these clamps can be a good way of teaching problem solving when it comes to workholding.

• 1.25″ x 1.25″ x 4.125″ 4140 steel (x1 per clamp)
• 1.5″ x 1.5″ x 0.5″ 4140 steel (x1 per clamp)
• 1/2″ UNC x 1″ long flat head socket cap screw (x1 per clamp)

123 SuperBlocks

What kind of dark sorcery is this, you ask?

This isn’t the trick of CAD magic. You really can do this with 123 blocks.

By alternating a pattern of counterbored threaded holes, you can use a socket head cap screw with a large undercut to bolt these 123 blocks together. The best thing about it is that the bolt heads are competely inside the blocks, so there is zero interference as you’re making a creative setup.

Now, keep in mind that these bolts aren’t terribly strong. They won’t be competing with a hold-down clamp with a 1/2 stud and handling heavy machining. But they’re really handy when you want to use these block in a machine setup and don’t want them to move between cycles. Or if you need to stabilize a part in a way that gravity doesn’t agree with. Or if you need a creative inspection fixture. You get the idea.

Fair warning: these take a little longer to make than the more traditional (and less useful) 123 blocks. But it’s time well spent. They’ll be the envy of everyone in the shop and they’re just really cool. That’s why I call them 123 SuperBlocks.

Most people make the sets of 123 blocks match ground in pairs. I’d really recommend making at least a set of 4 of this kind. I’d even do 6 if possible. Since they’re so stackable, the more you have the better.

Personally I like to use A2 for jobs like this since it’s an air quench and very stable. I used O1 when I was in school and it worked OK but not great. It’s more prone to cracking, especially around sharp corners and threads, so a few guys had to start over. That said, it’ll work if that’s all you can afford.

• 1″ x 2″ x 3″ A2 steel, oversized 0.035″ (1 pc per block)
• 1/4-20 x 1/2″ socket head cap screw (2 pcs per block)

You might also want to make sure that you’re using an oversized tap (H11) instead of a more common H3 or H5, especially if you’re using O1. It tends to shrink and warp a little bit when heat treated, so you might not be able to use the threads otherwise.

This is a dead easy project for something that’s actually pretty useful.

This is a tool that can help you keep your tap straight over a plate or a shaft. It has holes drilled to accommodate taps from #6 to 1/2″. The drawings specify mild steel, but you can use tool steel and heat treat it if you want it to last longer. If that’s the case, 4140 will work perfectly fine.

Even though this is a simple milling job, it’s a good opportunity to practice precision. The holes need to be aligned to the vee on the bottom. This can be an excellent exercise demonstrating how to precisely locate a vee using a pin and a depth mic to measure. You can use this to check both how it aligns to the outside edges as well as check the depth.

This is a good job for practicing how to align a vise. If you’re doing it on a CNC, there are also a bunch of drills to load up, so there’s some repetitive practice. The really nice thing about this is that it’s a handy tool and practical project that needs hardly any material.

• 1″ x 1″ x 4.125″ steel (1 pc)

Yep. Pretty basic.

Here’s the drawing:

Screw Jacks

This one is another classic. I made mine in a CNC course in college. One thing I didn’t like about the set I made, though, is that they were really limited on the amount of travel you could get out of them.

That’s why for this set, I included the drawings for the riser blocks. These should give you a really good amount of reach to make these worth keeping in your toolbox.

If you program them on the CNC, then you can get a really nice set. Technically the bare minimum that would be useful is 3 units, but I’d recommend making more than that. It seems that I’m always using about 6 at a time.

If you make a set of 6, make two riser blocks for each screw jack. If you run these on a CNC lathe, you should be able to do each piece in one operation. The only exception is that you might want to flip the screw, so it has a nice, smooth finish everywhere.

This is a good project for learning CNC lathes, and it also gives a great opportunity to wrap your head around clearances and unilateral tolerances. You can feel what the difference is between a slip fit of 0.005″ and 0.015″.

Here’s the BOM to make a set of 6 (2 risers, 1 body, 1 screw per unit):

• Ø 1.0″ x 8″ long 4140 HTSR (x1)
• Ø 2.0″ x 40″ long 4140 HTSR (x1)

I put those in as bar lengths with a little extra to grip on to near the end of the run. This is because usually this is a CNC job, so cutting them all up into individual pieces will just end up wasting material and taking longer.

This is a cool project.

Realistically, the most common approach to bending a piece of metal when you don’t have easy access to a proper brake is to shove it in a vise and wail on it with a hammer. This just makes that happen a little more professionally.

It’s got magnets that help it to just snap on to any steel vise. This is a tool that can give you accurate and clean bends in a very basic shop. The die is in three sections, so you can remove and adjust as needed if you’re working on smaller pieces.

This is one that most of your machinist buddies have probably never even seen, so it’s got a pretty high “nifty factor”.

The tool itself is pretty easy to make and mostly just teaches you not to put a workpiece in the milling vise the wrong way. What’s interesting about it though is that it’s a nice, very basic introduction to tool and die. This can be a way of learning some of the fundamental terminology and principles of sheet metal forming.

Since this probably isn’t something that’s going to see a ton of daily use, most guys just make it out of mild steel. If you want something that will last a really long time, make it out of 4140 instead and heat treat it.

• 2″ x 2″ x 6.125″ mild steel (2 pcs)
• 2″ x .25″ x 2.125″ mild steel (3 pcs)
• 8mm x 3mm neodymium magnets (8 pcs)
• 1/4-20 x 1″ long socket head cap screws (9 pcs)

Well, there you have it. 13 machining projects for students and beginners.

There’s definitely nothing wrong with many of the more “trinket” style of projects that are common in many machining programs. You can get very focused in the operations to hone really specific skills.

The nice thing about making tools, though, is that there’s a lot of pride that goes into the workmanship, and the fact that you might very well still have them in your toolbox after ten or twenty years.

There are a whole slew of other tools that can be make by beginners. Here are a few other ideas:

• Dial indicator articulating arm
• Drill point gage
• Edge finder
• Magnetic chip shield
• Center finder
• Live tailstock center
• CNC tool height presetter
• Bushing installation tool set

Types of Lathe Machines & Their Uses [Complete Guide] PDF

The lathe is defined as the machine tool, which is used for different machining operations such as turning, facing, threading, etc.

Lathe Machine and Types

A lathe machine is a machine that holds the workpiece on a chuck and tool on a toolpost, the lathe machine rotates the workpiece about an axis to perform different operations such as turning , facing , chamfering, thread cutting, knurling , drilling, and more with tools that are applied to the workpiece to design an object with symmetry about that axis.

The main function of a lathe is to remove the metal from a workpiece to give a required size and shape. In a lathe machine, the tool is held, and a workpiece is rotating about an axis rotation to perform various operations with different tools.

The lathe machine is primarily used to produce cylindrical surfaces and plane surfaces at a right angle to the axis of rotation. It can also produce tapers and bellows etc. Most suitable lathes can also be still used to produce most solids of revolutions, plane surfaces & screw threads, etc.

Parts of Lathe Machine

The following are the main parts of lathe machine :

• Feed mechanism
• Screw or thread cutting mechanism

The lathe bed is the base of the machine, which is a solid structure. It should be provided strictly under heavy pressure. On top of the bed, has the V-type of guideways include the angle of 90°.

There are two guideways provided, inner ways and outer ways, which are accurately machined to make them parallel to the axis. The lathe should take up the various vibrations, which are causing due to different types of force . The guideways provide sliding surfaces to the carriage and the tailstock.

The lathe bed must resist stresses due to the results of two important forces,

• The downward cutting force on the tool
• The force tends to move the tool away from the workpiece in a horizontal direction.

#2 Headstock

• H1: Geared headstock housing,
• H2: Intermediate gears lever,
• H3: High Low gear lever,
• H4: Camlock spindle,
• H5: Tumbler gears – forward/reverse and engage/disengage,
• H6: Quick change gearbox with 4 selectors (3 levers),
• H7: Lead screw,
• H8: Feed screw,
• H9: Forward reverse switch,
• H10: Change gear cover

It is located on the left-hand side of the lathe bed. It has a hollow spindle and different types of mechanisms for driving and changing the speed of the spindle.

In this case, the speed increases when the belt shifts from larger to smaller diameter pulleys . The spindle is made up of nickel, chrome steel, and carbon steel. The front end of the spindle hole is taper for holding the centers perfectly.

The speed changing is based on the following conditions,

• Hard and tough materials like cast iron – slow speed
• Soft materials like aluminum, brass – high speed.
• For high – speed hard tools made of tungsten carbide is used.
• For slow – speed medium hardness tool is used.
• Rough cut – high depth – low speed.
• For large diameter workpiece – low speed
• For smaller diameter workpiece – high speed
• For turning, boring, drilling – high speed
• For thread cutting, tapping, reaming – low speed

#3 Tailstock

The tailstock is located on the right-hand side of the lathe bed. The tailstock supports the other end of the workpiece when it is machining between two centers.

• T1: A feed screw
• T2: Reduction gearbox (optional)
• T4: Adjustable base
• T5: Spindle
• T6: Locking Lever

It holds the tool rigidly and perfectly for performing operations such as drilling, reaming, tapping, and boring. It can move along the guideways and can clamp in any position on the bed.

The tailstock is consist of the dead centre, spindle, adjusting screw, hand wheel, etc. The spindle can move forward and backward of the body called barrel by means of a handwheel. The keyway is provided on the inside surface of the barrel to hold the dead centre.

#4 Carriage

The carriage is one of the most important parts of the lathe tool and it will serve as a supporting, moving, and controlling part of the cutting tool.

It is ‘H’ shaped. The saddle fits over the bed and slides along the guideways by carrying the cross slide and tool post. It can lock in any position in its movement.

4.2 Cross Slide

It is an attachment to the saddle and to the compound rest. The cross slide move by the turning handwheel. Transverse movement is obtained when the nut mounted on the feed screw is engaged with the binder screw of the cross slide.

When a taper turning attachment is used the binder screw is open to disconnect the cross slide from the crossfeed screw and the cross slide is attached to the guide block. Cross slide can move automatically when the pinion is keyed to the crossfeed screw is in mesh with the apron gearing.

4.3 Compound rest

It is a circular base, graduated in degrees and it is used to obtain angular cuts and tapers of the variable cross-section. It consists of a compound slide handwheel, compound slide feed screw, compound slide nut. The compound slide handwheel is mainly used in taper turning operations to give the feed.

4.4 Toolpost

The tool post is placed above the compound rest, and it holds the tool firmly. There are different types of tool post,

• Single screw tool post
• Four-way tool post
• Eight-way tool post

#5 Feed Mechanism

The amount of tools relative to the workpiece is called ‘Feed.’

• Longitudinal feed: Here the tool moves parallel to the lathe axis. It is affected by means of the carriage movement.
• Crossfeed:  Here the tool moves at right angles to the lathe axis.
• Angular feed:  By adjusting the compound slide and swivelling it to the required angle to the lathe axis.

Cross and longitudinal feeds are both hand and power operated, but angular is only hand operated.

#6 Screw or Thread Cutting Mechanism

The lathe is important to the machine tool, which is used to cut the required type of threads on a given work. The rotation of the screw is used to move the tool along the workpiece to produce the screw threads . The half-nut mechanism is used in the lathe.

#7 Feed Rod

It is a long shaft having a keyway extending from the feed box across and in front of the bed. The power is transmitted from the lathe spindle to the apron gears through the feed rod.

The feed rod is mainly used to move the carriage or cross slide for the operations such as turning, boring, facing, and all other considering the thread cutting operation.

#8 Leadscrew

It is a long threaded shaft used for only thread cutting operations. The lead screw is in an arranged position in all operations from the gearbox. It may also be used to give the motion for turning, boring, etc., in the lathes, which are equipped with a feed rod.

Types of Lathe Machines

Following are the seven different types of lathe machine :

• Speed Lathe Machine
• Engine Lathe Machine
• Bench Lathe Machine
• Toolroom Lathe Machine
• Capstan and Turret Lathe Machine
• Special-purpose lathe machines
• Automatic Lathe Machine
• CNC lathe machine

#1 Speed Lathe Machine

These types of lathe machines are simple in construction. It has a bed, headstock, tailstock, and tool post mounted on the adjustable slide. There is no feed box lead screw or carriage.

The tool is mounted on the adjustable slide and is fed into the work purely by hand control. This characteristic of the lathe machines has a speed range from 1200 to 3600 rpm. The headstock construction is very simple and has only 2 or 3 spindle speeds available.

Speed lathe machine has less depth of cut. Light force and high speed made this to use this part woodworking, spinning, centering, and polishing. The name speed lathe has been given because of the very high speed of the headstock spindle.

#2 Engine Lathe Machine

Engine lathe is the most widely used lathe machine. These machines are driven by the gear mechanism or pulley mechanism. The name engine lathe is given because of the earlier lathe were driven by steam engines.

Engine lathe machine has all the parts similar to that of speed lathe. Such as bed, headstock, tailstock, etc. The headstock of an engine lathe is rigid in construction and has got an additional mechanism to get multiple spindle speeds.

Unlike the speed lathe, the engine lathe can feed the cutting tool both in the cross and longitudinal direction with reference to the lathe axis with the help of a carriage feed and leadscrew. These types of lathe machines are still used in workshops and many industries. It has three types Belt-driven , Motor-driven, and Gearhead type.

2.1 Belt Drive Lathe Machine

A lathe that receives its power from an overhead line shaft is a belt-driven lathe and is equipped with a speed cone and one or more back gears to get a wide range of spindle speeds.

2.2 Motor-Driven Lathe Machine

A lathe that receives its power from an individual motor integral with the machine is called a motor-driven lathe.

2.3 Geared-head Lathe Machine

A geared-head lathe gets its power from a constant speed motor, and all-speed changes are obtained by shifting various gears located in the headstock. It has no cone pulley.

#3 Bench lathe

These types of lathe machines are small in size and are used for very small precision work. Bench lathe machines are mounted on the bench. It has all the similar parts of the engine lathe and speed lathe. Bench lathe machine performs almost all the operations of the engine lathe and speed lathe. Its only difference is in size.

#4 Toolroom Lathe Machine

Toolroom lathe machine is the same as that of engine lathe but provides a wide range of speed. The spindle speed range is from very low to quite high speed up to 2500rpm.

This is equipped beside the other thing, with a chuck, taper turning attachment, draw in collect attachment, steady and follower rest, pump for coolant, etc. Toolroom Lathe is costlier as compared to the engine lathe. It is mainly using in grindings , working on the tool, dies gauges, and in machining work where is accuracy is needed.

5. Capstan Lathe and Turret Lathe

These types of lathe machines are used in production work. These lathe machines are the development of the engine lathe. These machines are provided with hexagonal turret heads instead of tailstock. It also consists of three tool posts.

In these types of lathe machines, multiple tools may be fitted and fed into the work in the proper sequence. The main advantage is that different operations and parts can produce in a very less amount of time. And also without changing the tool the quantity and quality are high.

Capstan and turret lathe requires more floor space than other lathe machines. Capstan and turret lathe is used for only large jobs.

Read the full article on Capstan and Turret lathe

6. Special Purpose Lathe Machines

As the name implies these types of lathe machines are used for special purposes and for production work. In this lathe, special operations are performed such as drilling , grinding , reaming , boring , etc.

The special-purpose lathe machines are:

• Wheel lathe machine
• Gap bed lathe machine
• T-lathe machine
• Duplicating lathe machine
• Missile lathe machine

1. Wheel Lathe Machine

The wheel lathe is made for finishing the journals and turning the thread on the railroad, automobile cars, and locomotive wheels.

2. Gap Bed Lathe

The gap bed lathe, in which a section of the bed adjacent to the headstock is removable, is used to swing extra large diameter pieces.

The “T -lathe” is used for machining rotors for jet engines. The axis of the lathe bed is at right angles to the axis of the headstock spindle in the form of a T.

4. Duplicating Lathe

The duplicating lathe machine is one of the duplicating the shape of a flat or round template onto the workpiece. Mechanical, pneumatic, and hydraulic devices are all used to coordinate the movement of the tool to reproduce accurately the shape of the template.

5. Missile Lathe Machine

The missile lathe machine which has a very large swing for accommodating long missile components of very large diameter is the most modern and latest in lathe design.

7. Automatic Lathe

In these types of lathe machines, all the work is done automatically. These are the high-speed heavy-duty, production lathes. In these types of lathe machines, once the tool is set, it performs all the operations automatically to finish the job.

Here the change of tools and feed is automatic. The single operator can control 5 to 6 automatic lathes at a time.

Lathe machine performs different operations such as turning, facing, taper turning, knurling, grooving, parting off, electric turning, thread cutting, reaming, etc. Let it take one by one as follows.

8. CNC Lathe Machine

These types of lathe machines are operated with a precise set of design instructions. A CNC (computer numerical control) lathe is a machine tool that rotates the workpiece around the main spindle, while a cutting tool cuts the workpiece into a desired shape and size.

A simple CNC lathe operates on two axes with the cutting tool in a fixed position on an 8 to 24 station turret. CNC lathe ensures consistent product quality and does not require highly skilled operators to operate the machine. On the other hand, CNC machines are more expensive than manually operated machines.

10 Cool Metal Lathe Projects to Hone Your Skills

A metal lathe is one seriously versatile machine, and turning is considered one of the 3 core machining operations . The lathe spins your workpiece at high speed, and you can bring a wide variety of tools against the material to cut and shape metal in lots of different ways, including facing, threading, boring and creating grooves, threads, and tapers.

As a result, you can make anything you can imagine with a metal lathe. Even the parts to build another metal lathe, as well as most of the stuff we talked about in our list of milling machine projects , and this list of CNC milling projects .

For a beginner, getting the hang of metal lathe operation takes some practice. But it’s also an engaging and rewarding pastime. So, if you’re looking for some projects that take full advantage of your metal lathe’s capabilities while helping you advance your skills, this list of cool metal lathe projects is for you!

Ready to make one ring to rule them all? When you create a ring with your metal lathe, you might feel like you did just that.

Because it involves several different metal lathe rough and finish techniques, making a ring is an excellent way to build your skills and confidence. Start with easy-to-machine materials like steel, then challenge yourself with harder-to-machine materials like aluminum after reading these tips for machining aluminum . Then further challenge yourself by making more advanced and ornamental designs as you get comfortable.

Metal rings make great conversation pieces and memorable gifts for loved ones, as well.

2. Machinist Hammer

Perhaps you already have a machinist hammer in your workshop. If not, time to get to work! It’s one of the most basic machinist tools to have around, and it’s another project well-suited to a beginner’s budding metal lathe skills.

Get started with a machinist hammer featuring the basic mallet-style head. For a bigger challenge, try a tapered handle. Then you can change your head design to make all sorts of different hammer types on your lathe, too. Here’s a helpful video showing the process of making a machinist hammer.

3. Spinning Top

Way before fidget spinners, there was the spinning top. It’s hard to think of a simpler, more iconic toy. Or one that demonstrates physics properties so well, for that matter. A handsome spinning top will look great on your desk or make a great gift.

This is another relatively straightforward project with lots of possibilities for variations, as well as opportunities to develop fundamental metal lathe skills. And it’s a small object that doesn’t take much material—just a single cylinder bar of your chosen metal.

4. Turner’s Cube

It may not have any actual use. But a turner’s cube is the stuff of legend and a sort of rite of passage in industrial trades.

Consisting of several nesting metal cubes, each bored out in similar ways, a turner’s cube is fascinating to look at. It’s also somewhat of a challenge to create, particularly since it requires a lot of planning as well as several of our other metal lathe tips .

And indeed, the challenge is the point of a turner’s cube. According to lore, the first of these was dreamed up as a way to test the skills of apprentice lathe operators, or “turners.” So now, let’s see what you’ve got!

5. Captive Nut

“Captive nut” may sound like an insult, but it’s actually the name for another fun little object you can make on a metal lathe that will get your friends and family talking.

The thing about the captive nut puzzle is that it takes multiple machining operations to create, including facing, drilling, turning to diameter, grooving, chamfering and single point threading. All of these represent fundamental lathe skills. So it’s not only a great way to make a good conversation piece; it’s also a great stepping stone to more advanced projects.

Next time you’re signing autographs for your fans, or marking up a print to let an engineer know they messed it up in the nicest way possible, maybe you’ll do it with a metal pen you made yourself.

Due to the small size and smooth curves, making a metal pen is a good test of lathe skill refinement. If you shape one that’s designed to accept a standard ballpoint pen replacement ink cartridge like fisher space pen refills, you’ve got yourself a practical, personalized writing tool to be proud of. Don’t lend it out to just anybody or you might never see it again!

7. Screw Jacks

A screw jack is a handy mechanical device for your shop. As the name implies, it has a screw that you turn with a handle to move a load along its axis. You can use a screw jack to lift, lower, or position heavy loads—useful when you’re working with chunks of metal.

You’ll need to start with metal stock that can provide enough load-bearing capacity. Then use your lathe to create the screw jack in several steps, including turning the metal stock to create the desired shape and size, threading the screw, and finishing the surface to the desired level of smoothness and precision.

What you’ll end up with is a practical tool and some more advanced lathe skills.

8. Magic Tube

A magic tube is similar in size and shape to the classic captive nut puzzle. This one may look simpler on the outside, but looks can be deceiving. The cool thing about the magic tube is that you can hide money or other valuable stuff inside it without any obvious way to get at it!

It’s another small-size project you can do with just a piece of scrap metal. The magic tube takes several steps but doesn’t have any specific critical dimensions you need to hit. So you have lots of leeway for how you make it and work on your lathe skills in the process.

Check out this helpful tutorial to make your own magic tube.

9. Mini Fire Piston

Who doesn’t get a kick out of fire making tools? A fire piston is a time-honored device that uses compressed air to ignite some kind of tinder. Some people call it a slam rod fire starter because that’s what you do with it for ignition. Not only is it useful – and potentially a lifesaver in a wilderness survival situation – it’s also fun to use.

You can make the piston and the cylinder it slides into on your metal lathe. The trick is that you’ll need to machine both the piston and the tube to tight tolerances. So it’s another good project to help refine your skills.

Here’s a quick video overview of making a fire piston on a lathe.

10. Machinist’s Scribe

We’ll finish our list with a classic tool for any machine shop. A machinist’s scribe isn’t the most complex project here, but it does involve several machining processes.

Although it looks a bit like a dentistry tool, it’s actually one of the most important devices you can own as a machinist learning the trade . Use the pointed tip and dykem to etch precisely measured markings on your workpieces for your cutting, drilling, or other machining operations.

If you don’t already have a machinist’s scribe, go ahead and make one today. You’ll wonder what you ever did without it!

One Last Note about Metal Lathe Projects
