ABRASIVE DISC AND ABRASIVE WHEEL COMPRISING THE LATTER

摘要

An abrasive disc (1), in particular for abrasive wheels (15) which can be driven in a rotating manner, comprising an outer edge (2) and an inner edge (3), which merge one into the other at a first point of intersection Si, wherein the inner edge (3) has, at least over part of its extent, a concave portion (7), which is formed such that it is congruent with a convex portion (16) of the outer edge (2), wherein the convex portion (16) of the outer edge (2) extends from the first point of intersection Si over a part of the outer edge (2) and wherein the concave portion (7) of the inner edge and the convex portion (16) of the outer edge (2) are arranged point-symmetrically in relation to each other.
