Abstract (en)

[origin: DE102004013192B3] The method involves having a cam shaft consisting of a steel tube. The cam directs the tube toward a grinding machine, with which after a sharpening procedure directs the cam shaft toward the same grinding machine. The cam shaft is arranged after a bearing finishing of the bearings and or a rough grind of the cams and or a bearing finishing of the cams is accomplished. The bearing of the cam shaft is finished on a first station of the grinding machine and the rough grind and the finishing bearings of the cams of the cam shaft take place on a second station. An independent claim is included for a device for sharpening bearings and cam of a built cam shaft.
