Abstract

A process for the metal-removing machining of a workpiece, where a disc-shaped external milling cutter is provided having cutting edges positioned on its outer circumference, the workpiece is rotated, and peripheral surfaces of the workpiece are machined with the milling cutter, by rotating the milling cutter to have a cutting speed of at least 180 m/min when roughing and at least 200 m/min when finishing, and a chip thickness of between 0.05-0.5 mm.
