Lathes and turning centers cut a rotating part with a stationary cutting tool. The tool moves parallel and perpendicular to the workpiece axis to provide the desired finished shape.
Polishers and buffing machines are used to impart a fine (low Ra) surface finish on the exterior of a part. To improve surface finish, they use use abrasive grain slurries or compounds on buffs, bobs, cloth naps, laps, very fine grit nonwovens, and coated abrasives.
