A grinding wheel comprises a disk-shaped body (12) which is equipped with a peripheral processing surface consisting of a grinding material. There is further provided an at least two-part flange (20, 21) retaining the body (12) on both sides thereof and provided with a mounting opening (22) for a holding arbor of a grinding machine. In order to achieve a centering effect between the body and the flange, with the simplest possible constructional means, a first flange part (20) is provided with a circumferential surface (34) whose cross-section, taken along a radial plane, exhibits the shape of an n-cornered polygon. The body (12) is in contact with the circumferential surface (34) via bolts (32) projecting radially inwardly. The number of bolts (32) corresponds to the number of the corners of the polygon. The bolts (32) can be rotated relative to the circumferential surface (34) in the circumferential direction.
