摘要： 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
