ABSTRACT:
The present invention relates to a method for grinding of cam profiles on a camshaft (1), having an inner shaft (5) and an outer shaft (4) arranged coaxially one inside the other and mounted to rotate with respect to one another. The camshaft (1) additionally has first and second cams (2, 3) that can rotate with respect to one another over a limited circumferential angle about the camshaft axis (6), the first cams (2) of which are fixedly connected to the inner shaft (5) and the second cams (3) of which are fixedly connected to the outer shaft (4). It is essential to this invention that during and/or after the grinding operation a fluid is forced under pressure into the outer shaft (4), thereby preventing penetration of grinding dust into the interspace (8) between the first cams (2) and the outer shaft (4) or flushing out any grinding dust that has already penetrated.
