摘要： 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.
