1. A workpiece mounting system for a grinding machine, the workpiece mounting system comprising:
a magnet core mounted on a spindle, the magnet core comprising a cylindrical, elongate receiving region having a central axis;
a magnet coil, the magnet core positioned inside the magnet coil;
a rapid-mounting mandrel arranged for insertion into the cylindrical, elongate receiving region of the magnet core; and
a discoid workpiece driver, detachably fastened to the rapid-mounting mandrel and extending normal to the central axis, wherein:
the magnet core comprises a rapid-mounting device for mounting the rapid-mounting mandrel in the magnet core;
the rapid-mounting device is integrated into the cylindrical, elongate receiving region of the magnet core; and
the rapid-mounting device is formed as a hydraulic mounting device, the hydraulic mounting device comprising pressure elements configured to apply pressure and contact the rapid-mounting mandrel in order to mount the rapid-mounting mandrel.
