Patent ID: 8020293

Claim:
A method for machining bearing seats of a main bearing and a rod bearing of a crankshaft having a longitudinal axis, wherein the bearing seats, after primary forming of the crankshaft by forging or casting, are subjected to the following machining operations: forming by a chip-removing machining with specific cutting edges, performing a deep-rolling of all fillets or undercuts, performing a straightening-rolling of the crankshaft, performing a chip-removing precision machining with an end-milling cutter, respectively by a roughing-cut turn-milling and a finishing-cut turn-milling, respectively during substantially 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 end-milling cutter, and a smooth-rolling after the finishing-cut turn-milling.
