Patent ID: 7882633

Claim:
A method for machining the bearing seats of a crankshaft, wherein the bearing seats are subjected to the following machining operations after a crankshaft having a longitudinal axis has been initially formed by forging or casting: rough-shaping by chip-removing machining with specific cutters, hardening, passing through dressing rollers, rough rotary milling and finish rotary milling via a milling cutter, wherein the rough rotary milling and the finish rotary milling are respectively applied substantially during one complete revolution of the crankshaft, without longitudinal feed, and without tangential feed, relative to a tangential surface of the respective bearing seat, of the milling cutter, and the infeed of the milling cutter during immersion at the beginning of the rough rotary machining and at the beginning of the finish rotary machining has only an axial component relative to the rotation axis of the milling cutter.
