摘要：
The invention relates to a method of machining the bearing seats of main and rod bearings (HL, PL) of crankshafts (1), in which the bearing seats (30) of the main and rod bearings (HL, PL), after the primary forming of the crankshaft (1) by forging or casting, are subjected to the following processing operations: forming by machining with a specific cutting edge, deep rolling of all fillets or recesses of the main and rod bearings, straightening of the crankshaft (1), precision machining with an end-milling cutter (12) in each case by high-speed roughing-cut turn-milling and finishing-cut turn-milling, smooth rolling of the bearing seats of the crankshaft after the finishing-cut turn-milling, wherein the roughing-cut turn-milling and the finishing-cut turn-milling is effected during in each case an essentially complete revolution of the crankshaft (1) without longitudinal feed and without tangential feed of the end-milling cutter (12).
