Abstract
A grinding disk for forming a spur gear includes a single integral disk member having a grinding surface including a finish grinding tooth and a pre-grinding tooth. The finish grinding tooth has a profile corresponding to the desired configuration of the flanks of adjacent teeth and the tooth gap therebetween for a given spur gear to be formed. The pre-grinding tooth has a profile formed by curved surfaces only. The finish grinding tooth and the pre-grinding tooth are spaced by distance equal to one tooth pitch between adjacent teeth of the spur gear to be formed.
