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.

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…

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.

Our returns policy is easier than ever. We understand that if an item isn’t correct, then it needs to be returned. If you are wanting to return anything supplied by Cutwel please see our returns page for full instructions.

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.

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

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 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.

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.

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

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.

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.

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

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

To mainland UK we offer FREE UK next day delivery on all orders above £59 ex vat*. For orders under £59 ex vat we offer the following:

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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

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

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.

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.

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.

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

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.

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.

Vardex threading insert gradespdf

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.

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

Vardex threading insert gradesexplained

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

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.

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.

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.

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

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:

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

*T’s & C’s and exclusions apply. Please see our delivery page for more information on all our services including those outside of mainland UK (Republic of Ireland, Northern Ireland, Scottish Highlands, Channel Islands etc).

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

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

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.

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.

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

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