ABSTRACT:
A grinding disk base body is fixable to the centering section of a grinding spindle rotor in a centering manner by the base body which includes an inner recess from which two fixed projections project inwardly. The base body also includes a mobile supporting element in the form of a cam disk that is supported on two bearing rods in a recess of the base body. The cam disk has an engagement opening for a torsional tool. When the cam disk is twisted, it can be supported or brought back against the centering section. The cam disk is retracted when the base body is displaced towards the centering section, and is supported against the centering section for the final centering. The fixed projections and the cam disk are preferably arranged in such a way that the action line of the cam disk is in the median line of the fixed projections.
