  • Patent number: 8020293
    Abstract: 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 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).

  • 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).

  • Patent number: 7168548
    Abstract: The invention relates to a flexible production line for machining undulated workpieces arranged individually or in groups on a pallet, in a plurality of successive operations (OP-20, OP-40) carried out along from pallet stores. In order to machine series' of workpieces, the entire production line is divided into a plurality of decoupling modules. A plurality of operations (OP-20, OP-40) are associated with each decoupling module. A stacker for individual pallets is associated with each decoupling module. Each decoupling module has at least one store for pallets and the decoupling modules are interconnected by transfer conveyors.
