ABSTRACT:
Apparatus for grinding irregular surfaces of a workpiece includes a frame, a slide movable longitudinally on this frame, a shaft mounted for rotation on the slide and having a workholder mounted on it, a grinder adapted to contact the surface to be ground, and gearing operable by movement of the slide to cause the shaft to simultaneously rotate and move longitudinally to bring the surface to be ground into contact with the grinder. The frame is slidably movable on a base which supports a cam in contact with a cam follower on the shaft so as to move the workholder away from the grinder when there is a gap in the surface to be ground.
