The metal lathe is used to remove material from a workpiece mounted on the rotating spindle. The spindle receives power from the electric motor through the gears and belts in the headstock.

Tools used for turning or threading the workpiece are mounted on the carriage or tailstock. The tooling is moved parallel or across the workpiece by moving the carriage or cross slide. The move- ment of these mechanisms is controlled manually by handwheels or automatically with the power feed.

Spindle speeds are selected by configuring the gears and belts in the headstock. Power feed rates of the carriage or cross slide are selected by configuring the change gears and feed rate selectors.

The usual cutting operations for this lathe include facing, turning, parting, drilling, reaming, grooving, knurling, and threading. There is a wide variety of tools and workpiece holding devices for each of these processes.
