Abstract
A grinding disc comprises a grinding layer formed of grinding grains bound by means of a binding agent. Reinforcing fabrics are embedded in the grinding layer on the outer sides of the grinding layer. At least one additional fabric is arranged on at least one of the reinforcing fabrics and has a respective diameter which is smaller than the diameter of the rein-forcing fabrics. The at least one additional fabric stiffens the grinding disc in a region around a central opening and improves the properties of the grinding disc during rough machining and/or cutting off

- which is embedded in the grinding layer on the first outer side,
- which has a first fabric diameter DA1, wherein:
- DA1≥0.8·DS,
- a second reinforcing fabric,
- which is embedded in the grinding layer on the second outer side,
- which has a second fabric diameter DA2, wherein:
- DA2≥0.8·DS,
- wherein at least one fabric is arranged on at least one of the reinforcing fabrics, and
- wherein the at least one fabric has a respective diameter Di, wherein:
- Di<DA1 and Di<DA2.
