Abstract (en)

What is described is a wheel-holder flange for a cup wheel (2) of the type in which the wheel comprises a support (3) bearing the abrasive material and the support may be detachably locked on the flange so that it can be fixed in rotation with the flange about an axis of rotation (X) of the wheel. The flange comprises a first device (6) for locking the wheel support (3) on the wheel-holder flange by magnetic attraction, and a second device (7) for locking the wheel support (3) on the flange, in which the locking may take place by the action of the forces of a centrifugal nature generated by the rotation of the wheel, and in which the second locking device (7) comprises at least a pair of retaining blocks (10, 10') held in such a way as to be able to slide in a limited manner on the flange and able to be radially urged, by centrifugal action, to engage a recess (11) provided in the wheel support (3) so as to oppose relative movements between the flange and the wheel support, principally in the axial direction, during the rotary movement of the wheel (2).
