  • Patent number: 7882633
    Abstract: Disclosed is a method for machining the bearing seats (HL, PL) of shafts (1), especially crankshafts. According to said method, the bearing seats (HL, PL) are subjected to the following machining operations after initially shaping a shaft (1) in a forging or casting process: the bearing seats (HL, PL) are preformed by cutting the same using a specific cutting edge; they are hardened; they are passed through dressing rollers; they are subjected to a preliminary rotary milling process; and they are subjected to a final rotary milling process. The preliminary and the final rotary milling process are carried out during substantially an entire rotation of the shaft (1) without longitudinally or tangentially advancing the milling cutter (12).

  • Publication number: 20080008550
    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).
