The present invention relates to a crankshaft or a cam shaft under 10㎛, preferably the method for 5㎛ than final size tolerance (Rz) and 30㎛ or less, preferably precision machining with a tolerance of concentricity 6㎛ below and apparatus. The crank shaft or the cam shaft is processing is at least partially cured. According to the invention, the initial processing, and 45HRC to 60HRC, preferably after subsequent curing of 50HRC to 53HRC, the final process is performed using CBN or PCD insert the cutting insert. For this purpose, the device used is provided with the CBN or PCD inlets equipped with the cutting insert (12, 13, 14), wherein laterally, the cutting insert oriented in the radial and tangential direction are arranged one after another alternately .
