Abstract

A rough grinding wheel has a plurality of annular grooves with widths at the surfaces of the grooves that are less than the widths thereof at the bottoms of the grooves. This feature provides a space for fluid during the grinding process. A finishing wheel may be mounted on a common shaft with the rough grinding wheel. The rough grinding wheel is intended for use in a method for grinding the outer contour of a cam wherein the cam is rough-ground with the roughing wheel; after a first radial infeed, the rough grinding wheel is withdrawn and axially displaced for a second infeed; this process is repeated until the cam is rough-ground.
