Abstract:
A method of grinding a cam having a concave flank on a camshaft, comprising:providing a grinding wheel with a grinding zone for finish-grinding of the cam;supporting said grinding wheel by a grinding spindle aligned along a spindle axis;aligning said spindle axis at a predetermined angle of about 10.degree. to 30.degree. relative to a longitudinal axis of the camshaft, said grinding zone of said grinding wheel being defined by a conical outer surface of said grinding wheel which has been dressed relative to said spindle angle at a grinding zone angle which is substantially equivalent to said predetermined angle; andcarrying out grinding operations on the camshaft by tracking the grinding spindle, along with the grinding wheel, in the direction of a vertical advance axis running perpendicular to an infeed axis and a longitudinal positioning axis of the grinding spindle, such that the grinding zone of the grinding wheel is maintained at a same position on a generatrix of the grinding wheel.
