For the recessing groove cutting edge, the longitudinal feed is employed. The front clearance angle depends upon the bore of the work. A parting off tool is normally forged and used as bits for cemented carbide tipped tools. Parting off tool is made as narrow as possible to remove the minimum of metal. The width of the cutting edge range from 3 to 12 mm only. The length of the cutting tool which inserts into the work should be slightly longer than the radius of the bar stock being machined.

As the tool penetrates deep into the work, clearance is provided all around the tool cutting edge to prevent it from rubbing against the work surface. As the tool is purely ended cutting it has no side rake slight back rake is provided on the tool to promote an easy flow of the ships.

A right-hand tool is shown in the figure. Is that which is fed from lathe bed, i. A right-hand tool is formed on its left-hand end when viewed from the top with its nose pointing away from the operator. The left-hand tool is shown in the figure. Is that Long Handle Lathe Tools Pdf which is fed from the Left to the right-hand end of the lathe bed, i. The left-hand tool is used for left-hand thread cutting operation or turning operation which leaves a shoulder on the right-hand end of the workpiece.

A left-hand tool has its cutting edge formed on its right-hand end when viewed from the top with its nose pointing away from the operator. A round nose turning tool sown in the figure. Maybe fed from left to the right or from right to the left-hand end of the lathe bed away.

For this reason, they have no back rake and side rake. In some cases, a small back rake is provided on the tool. A round nose turning tool is usually used for finish turning operation. If you found this article helpful please share with your friends. Download PDF. Email Address.

He completed his engineering studies in and is currently working in a large firm as Mechanical Engineer. He is also an author and editor at theengineerspost. Manufacturing Machines. And also you 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.

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.

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

So how many types of Lathe Machine are there? Lathe machine has been categorized into the following types :. We are going to study each and every important point of these 8 different types of lathe machines.

Center or Engine Lathe Machine is the most widely used lathe machine and still, it is, in every workshop, this machine is present. The operation like Turning, facing, grooving, Knurling, threading and more, such operations are performed on this type of machine.

Engine lathe machine has all the parts such as bed, Saddle, headstock, and tailstock, etc. The headstock of an engine lathe is rigid and tailstock is moveable which is further used to support an operation like knurling.

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

Speed lathe is also called as Wood Lathe. The headstock spindle is rotating at a very high speed. The feed we provide is manually operated. The capstan and turret lathe machine used for Mass production large Quantity and it 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 provided by hexagonal turret head instead of the tailstock in which multiple operations Turning, facing, boring, reaming performed in a sequence without changing its tool manually, after each operation the turret rotated. The main advantage of using capstan and turret lathe is even less skilled operators can do a job.

The parts are almost the same similar to engine lathe machine 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, dies gauges and in machining work where accuracy is needed.

This type of lathe machine is small in size and use for very small precision work. It has all the similar parts of engine lathe and speed lathe. Standard lathes have some drawbacks i. But automatic lathes are used for mass production.

Some mechanisms are responsible for the automation in it. Having this machine the main advantage is that a single operator can handle machines more than 4 to 5 machines at a time. Some examples of special lathes include Vertical lathes, Wheel lathes, T-lathe, Multi Spindle lathes, Production lathes, Duplicate or tracer lathes , etc.

Wheel lathe is used for machining of journals and rail rods. It is also used for turning the threads on locomotive wheels. The axis of the lathe bed is at right angles to the axis of the headstock spindle in the form of a T. 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.

It 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 starts operation without changing code in the next time. These types of lathes are also used for mass production like capstan and turret but there is no programmed fed system. Before continuing any operation in lathe we have to load the job and center it on the head-stock spindle. In lathe operations , the headstock spindle holds the job and it rotates with the same speed as the spindle.

The carriage holding the tool on the tool post, also the carriage gives the tool post moves longitudinally or crosswise direction to give the desired feed on the job. These two motions longitudinally and crosswise helps to remove the chips of the metal and giving the proper shape of the job. It is tough to mentioned which operations are not performed in a lathe machine tool, though we discuss some important lathe operations in detail.

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 Lathe Tools Pdf Jpeg to hold between two centers. Head-stock and Tail-stock.

Facing operation is for making the ends of the job to produce a smooth flat surface with the axis of operation or a certain length of a job. The operation by which we remove the excess material from the workpiece to produce a cone-shaped or a cylindrical surface. This operation is done to produce a cylindrical surface by removing excess material from the workpiece. A shoulder turning is called which has a different diameter to form a step from one diameter to another.

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 finish turning operation needs high cutting speed, minimum feed and a very small depth of cut to generate the smooth surface. In finish turning the depth of cut is around 0. 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.

Any increase in the length of taper will require the use of a wider cutting edge which may destroy the workpiece due to the vibration and spoil the workpiece. Job is held between the centers. The length of the workpiece will be long enough. An only a small taper on a long job is done by this process. Chamfering is used for beveling the end of a job to remove burrs, to look better, to make a passage of the nut into the bolt. Knurling tool is held rigidly on the tool post and pressed against the rotating job so that leaving the exact facsimile of the tool on the surface of the job.

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. The tool should be set exactly to the height of the centerline of the job and at 90 degrees to the job.

In this operation, the job is rotated at the turning speed on the lathe axis and the drilling tool fitted on the tail-stock spindle. And the tail-stock is moved towards the job by hand feed. In this operation, we can enlarge the diameter of the existing hole on a job by turning inside with some farm tool known as a boring tool.

Reaming is the operation for sizing or finishing a drilled hole to the required size by a tool called reamer. In this operation, the job of this sheet metal is held between the former and the tail-stock center rotates at high speed with the former.
