A lathe is a machine tool that rotates a workpiece about an axis to perform various operations such as cutting, sanding, knurling, drilling, and deformation. There are several types of lathes including engine lathes, bench lathes, tracer lathes, automatic lathes, turret lathes, and computer numerical controlled (CNC) lathes. Lathe operations include turning, facing, boring, drilling, threading, and knurling. Cutting tools and work holding devices like chucks and collets are used to secure the workpiece for machining.
