ABSTRACT:
A rotating grinding or polishing device includes a number of grinding or polishing discs formed of two or more layers of segments radiating from a central retaining area having an edge which defines a central hole. In the central area, the segments are kept together by a heat-activatable string which also maintains the grinding or polishing disc in the form of a ring, whereby the disc has the required optimum stiffness/flexibility for obtaining an effective grinding or polishing finish so that even complex surfaces can be effectively ground or polished.
