Parts of Lathe Machine and there Functions Previously I posted an article about the different part of Lathe Machine. The parts of the carriage are: a) Saddle. The direction of motion of tool is called feed. The dial tells you when to engage the half nut lever so the tool follows the same thread groove every time. The metal lathe is divided into four major components: the bed, the carriage, the tailstock and the head stock. It can be moved along the bed either towards or away from the headstock. It is used to get the required shape and size of the job. Lathe Machine Parts: Bed:. Understanding Lathe Machine Carriage. Main parts of lathe machine. backgears. Viewed from the operating position in front of the machine, the headstock is mounted on the left end of the bed and the tailstock on the right. The bed of a lathe machine is the base on which all other parts of lathe are mounted. Headstock 9 8. 01.Headstock. Now come to its major mounting parts like headstock, tailstock, carriage, compound rest, cross slide, lead screw, feed rod etc. If someone wants to start working in manufacturing industries, they must have to know how to operate a lathe machine. 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. • Tailstock: Fits on the inner ways of the bed and can slide towards any position the headstock to fit the length of the work piece. Lead screw. They are used in almost every manufacturing industry. Carriage is located between the headstock and tailstock on the lathe bed guideways. d) Compound rest. Operations Done by Holding Workpiece Between Centres Turning: It is the most common type of operation in all lathe machine operations. In this article I will try to discuss all the functions of the parts in details. Compound Rest: Mounted to the cross slide, it pivots around the tool post. Lathe machine manufacturing is difficult, so first we make pa rts of the lathe machine, then we assemble all part of the machine. Stuck chucks.
