A process for the grinding of cam elements of an adjustable camshaft

A process for the grinding of cam elements (10) of an adjustable camshaft (1), wherein the article to be sanded cam members (10) fixed to an outer shaft (11) of the adjustable cam shaft (1) are arranged, and wherein on the outer shaft (11) rotatable cam elements ( 12) are added, which are connectable to an inner shaft, which inner shaft (in an inner space 20) of the outer shaft (11) can be arranged, the method comprising at least the following steps: - clamping the outer shaft (11) with the fixed cam elements (10) and with the rotary cam elements (12) in a grinding apparatus, - providing a gripping device (13) and engaging at least one rotatable cam element (12) so that the rotary cam member (12) by the gripping device is held (13), so that co-rotation of the rotatable cam member (12) on the outer shaft (11) is prevented , and - abrasive machining of the fixed cam member (10) under rotation of the outer shaft (11) and the fixed cam elements (10).
