Abstract:
1. A method for grinding of cam profiles on a camshaft ( 1 ), which camshaft ( 1 ) has an inner shaft ( has first cams ( wherein during the grinding process and/or thereafter, the method includes: forcing fluid under pressure into the outer shaft ( 4 ), thereby forcing fluid into a ring space ( 15 ) between the inner shaft ( 5 ) and outer shaft ( 4 ), wherein the fluid flows through a longitudinal hole ( 13 ) and into a ring gap ( 8 ) between the first cam ( 2 ) and the outer shaft ( 4 ) thereby preventing grinding dust from penetrating into the ring gap ( 8 ) or flushing out any grinding dust that has already penetrated into the ring gap ( 8 ).
