Abstract

In this grinding machine for tools, the receiving spindle for the rotary cutting tool (6) to be ground is driven without play by a stepping motor (18) via a high reduction transmission (10-19). In order to index the rotary cutting tool by a division, the sensor (23) is pivoted out briefly and the stepping motor (18) is switched on until the sensor (23), which has been pivoted in again, signals the next cutting edge (8). The indexing may also be controlled by a counter in which there is stored the stepping number corresponding to the respective cutter division. Time is saved as a result of this form of indexing. <IMAGE>
