Abstract: In a method for machining the bearing seats (HL, PL) of shafts (1), especially crankshafts, the bearing seats (HL, PL) are subjected to the following machining operations after the shaft (1) 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. Each of these rough rotary milling and finish rotary milling steps is applied substantially during one complete revolution of the shaft (1), without longitudinal feed and without tangential feed of the milling cutter (12).
