Abstract
It has been hitherto customary durig machining of workpiece, such a grinding of gear wheels, to slip a roller cage over the gear wheel. The chuck jaws of the chuck then hold the workpiece by way of the rollers in a roller cage. The time concuming operation is made superfluous by a holding ring which is mounted in the chuck. The holding ring has openings near the chuck jaws, and also has in this region fixedly installed roller-cage-type segments. Input guides at the holding ring allow quick, safe and secure exchange of the workpieces.
