Abstract (en)

[origin: DE4426452C1] The proposal is for a process and a machine for grinding concave-flank cams of a camshaft using a first and a second grinding wheel for pre and finish-grinding the cam, in which the pre-grinding process gives the cams a modified intermediate shape, and a third grinding wheel, the diameter of which corresponds to about double the radius of the concave flanks, whereby the concave flanks are pre-ground while stationary with said longitudinally moving third grinding wheel.
