Abstract
Apparatus for grinding to predetermined contour a plurality of eccentric cams on a cam shaft, comprising abrasive belts supported adjacent the cam shaft for linear movement such that the belts grind the peripheries of the cams. The belts are guided along a variable path according to the cam contour desired by shoes engaging the belts at their points of contact with the cams. The shoes are mounted on actuators powered by motor units controlled by CNC controllers. A coolant distributor for each belt is capable of flexing the belt to compensate for shoe movement.
