ABSTRACT:
A grinding wheel which is mounted on the tool spindle of a grinding machine is detached from the tool spindle and is transferred onto a second spindle while the two spindles rotate. Reattachment of the grinding wheel to the tool spindle also takes place while the two spindles rotate. This saves time and reduces the wear upon the bearings and upon the brakes for the tool spindle. If a grinding wheel on the tool spindle is to be replaced with a different or fresh grinding wheel, the machine uses two additional spindles one of which serves to accept a grinding wheel from the tool spindle and the other of which delivers a different or fresh grinding wheel to the tool spindle.
