Lathe machine is a machine tool that removes the material from the surface of workpiece with the help of cutting tool placed either perpendicular or angular w.r.t. workpiece. It was a detailed article on Lathe Machine Parts and Functions.
You can find the detailed explanation of Lathe machine along with its Definition, Accessories, Types, Working Principle, Specifications, Operations, Applications, Advantages, and Disadvantages HERE.
Below is the explanation for various parts of lathe machine.
The Parts of the lathe machine are as follows.
The line diagram of lathe machine was placed below.
The detailed explanation of all the parts is as follows.
Grey C.I: It is used for manufacturing of bed of the machine because it has high damping qualities and rigid qualities.
Casting is a manufacturing method because it gives high damping qualities.
The shape of the bed is selected such that the reduction in the rigidity of machine tool should be minimum and it should provide the maximum amount of the space.
Head stock is the widely used component on lathe machine. It is generally used to load the workpiece into the chuck and perform various operations.
It is a work holding device used for holding the workpiece at one end.
Chuck Is classified into two types:
Three jaw chuck:
It is used to hold circular or cylindrical shape jobs.
Four jaw chuck:
It is used to hold non-circular jobs.
At various speeds, It is used for transmitting power from spindle to the lead screw.
To avoid multiples start of the thread with multiple cuts, Thread chasing Dial is used in thread cutting.
For converting rotational movement into linear movement, Split nut with the lead screw will be used.
The carriage is the device used for carrying a moving part in a lathe machine globally.
It is used for moving the tool locally.
Quill will be used for the localized movement of the Dead Centre.
To perform the taper turning operation, the compound rest is used.
Tailstock and Headstock were placed opposite to each other. If the workpieces are small then there is no need of Tailstock.
It is used for supporting the large workpiece at the other end.
It can slide on the bed guideways and can be clamped in any position of lathe machine.
It is the device which is used for holding the tool. The tool post can rotates w.r.t. the position of the workpiece.
The cross slide is moved by the feed screw, is a part of the carriage that allows the movement of a tool at right angles to the bed guideways during machining.
An apron is situated on the carriage which consists of all controlling and moving mechanisms of carriage.
The legs of lathe machine are made up of cast iron which has the ability to absorb the vibrations induced during machining process.
The pan is used to collect the chips during machining operation. When you are removing the material from the surface of workpiece, all the chips from the specimen will drops into the pan and will be collected by it to avoid any damage to the human body .
The main function of lathe machine is to remove the material from the surface of the workpiece to give the desired shape and size as per the dimensions.
Its function can be satisfied by performing various operations on the lathe machines including CNC machine. The various operations are as follows.
The size of the lathe is specified according to:
The Lathe Machine Accessories are as follows.
