摘要

A system for connecting a disc to a disc holder, e.g. for grinding or polishing purposes, has a disc with an operating surface, an opposite connection surface and a protrusion which is mounted to said connection surface. The disc holder has a supporting surface for supporting the connection surface of the disc and a socket in the supporting surface of the disc holder for receiving said protrusion. The connection surface of the disc and the supporting surface of the disc holder are provided with fixation means which are distributed over the said surfaces outside the protrusion and the socket respectively.
