Abstract

Il presente trovato ha come oggetto un disco abrasivo per macchine smerigliatrici, con mezzi di aggancio perfezionati, che comprende un corpo discoidale, provvisto di un foro centrale e supportante su una faccia, una zona anulare in materiale abrasivo. La peculiarità del trovato è costituita dal fatto di presentare, in corrispondenza del foro, almeno una porzione filettata, atta ad impegnarsi con il codolo filettato di una macchina smerigliatrice, per l'aggancio del disco abrasivo alla macchina smerigliatrice medesima.The present invention relates to an abrasive disc for grinding machines, with improved coupling means, which comprises a disc-shaped body, provided with a central hole and supporting on one face an annular area of abrasive material. The peculiarity of the invention is constituted by the fact of having, at the hole, at least a threaded portion, suitable for engaging with the threaded tang of a grinding machine, for hooking the abrasive disc to the grinding machine itself.
