PROBLEM TO BE SOLVED: To provide such a method for simultaneously milling all connecting lever journals of a crankshaft as dispensing with the control of a side milling cutter to copy guide a connecting lever journal. SOLUTION: With regard to a method of respective crankshafts stored in two chucks of a rotating device having crankshaft connecting lever journals rotating around the axis milled by means of a side milling cutter, all connecting lever journals of a crankshaft 6 are milled by respective side milling cutters 34, 35, 36 of a side milling cutter group 12 including an eccentricity 'e' of the connecting lever journals and, at that time, the side milling cutter group 12 is driven at a rate of 1 to 1 with respect to the rotating crankshaft 6 and fed in the 'x' axial direction. |
