Carriage … Tailstock 4. Each of these major components includes different subparts with distinctive purpose for machining. Principle parts of a lathe 7 6. Functions of lathe Machine. Now understand bit about all these parts. 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. Operates the Cross-slide across (or perpendicular to) the bed. If someone wants to start working in manufacturing industries, they must have to know how to operate a lathe machine. The following part of Lathe serves as housing for the driving pulleys and back gears . Here we will see what is lathe machine, how it works, the main parts of the lathe machine and its operation. Hand Wheel: It is the wheel which is operated by hand to move cross slide, carriage, tailstock and other parts which has hand wheel. These machines have a milling column rising up above the lathe bed, and they utilize the carriage and topslide as the X and Y axes for the milling column. Feed mechanism 6.
