Abstract
A method for grinding the outer contour of a cam wherein the cam is rough-ground with a roughing wheel having circumferential grooves in its surface. After a first radial infeed, the grinding wheel is withdrawn and axially displaced for a second infeed. This process is repeated until the cam is rough-ground. A rough grinding wheel for use in this method has a plurality of annular grooves with widths at the surface 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.
