What is the primary function of a lathe machine?

The primary function of a lathe machine is to shape workpieces by rotating them against cutting tools. Lathes operate on the principle of rotational motion, where the workpiece is securely mounted on a spindle and rotated at high speeds. As the workpiece spins, various cutting tools are brought into contact with it to remove material, resulting in cylindrical shapes and other profiles. This process allows for precision turning, threading, and finishing operations, making lathes essential for producing components with accurate dimensions and smooth surfaces.

While drilling holes is a function associated with certain attachments or operations of a lathe, it is not the machine's primary purpose. Measuring dimensions and fastening components are also not functions of a lathe but rather tasks that can be performed using different tools or machines in a workshop.
