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.
Claims14
Process for the metal-removing machining of a crankshaft, comprising the steps of
- providing a disc-shaped external milling cutter having cutting edges positioned on the outer circumference thereof and having a diameter larger than the necessary penetration depth for the crankshaft to be produced at the big-end journal remote from the cutter,
- rotating the crankshaft, and
- machining peripheral surfaces of the crankshaft only with said cutting edges positioned on the outer circumference of said milling cutter, by rotating the milling cutter parallel to the crankshaft 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, and machining the journals by a climb-cutting process relative to the machining point.
