The origin of turning dates to around 1300 BCE when the Ancient Egyptians first developed a two-person lathe.

A metalworking lathe from 1911, showing component parts: a – bed b – carriage (with cross-slide and toolpost) c – headstock d – back gear (other geartrain nearby drives leadscrew) e – cone pulley for a belt drive from an external power source f – faceplate mounted on spindle g – tailstock h – leadscrew is a tool that rotates the workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, turning, with tools that are applied to the workpiece to create an object with symmetry about that axis.

Lathes are used in woodturning, metalworking, metal spinning, thermal spraying, parts reclamation, and glass-working.

The headstock contains high-precision spinning bearings. Rotating within the bearings is a horizontal axle, with an axis parallel to the bed, called the spindle.

Spindles are often hollow and have exterior threads and/or an interior Morse taper on the "inboard" (i.e., facing to the right / towards the bed) by which work-holding accessories may be mounted to the spindle.
