Abstract
Embodiments described herein generally relate to a grinding disc is being rotatably drivable around an axis of rotation. The grinding disc has a front side as well as a rear side facing away from the front side. The grinding disc further includes a multi-layered circular grinding blank packet with a plurality of circular grinding blanks. The grinding blanks are flatly stacked over each other along the axis of rotation and in which each grinding blank includes a central through opening. The central through openings form together a recess of the circular grinding blank packet. Wherein the grinding disc has a backing plate, which is arranged in the recess, and the circular grinding blanks each are fixed individually to the backing plate.

A grinding disc being rotatably drivable around an axis of rotation and having a front side and a rear side facing away from the front side, the grinding disc comprises:
- a multi-layered circular grinding blank packet with a plurality of circular grinding blanks, each having an uninterrupted continuous planar surface, the circular grinding blanks being stacked over each other along the axis of rotation, each of the circular grinding blanks having a central through opening,
- wherein the central through openings form together a recess of the circular grinding blank packet, the recess defining a stepped inner profile in which each succeeding blank defines a different inner diameter, and
- wherein that the grinding disc has a backing plate arranged in the recess so that more than one of the circular grinding blanks are fixed individually to the backing plate along a flat support surface of each grinding blank which is in contact with a stepped opposing surface of said backing plate.
