ROTATING DISC FOR MACHINING MATERIAL SURFACES

Proposed is a method for producing a rotating disc for machining material surfaces, said disc comprising a disc-shaped main body (10), which has a central receptacle (14) for direct or indirect connection to a drive shaft, and a material machining coating (18), which is applied to a ring zone (12) of the main body (10) that is arranged on an end face, comprising the following steps: placing glass fabric mats in a mold cavity of a production tool; compressing the glass fabric mats in the production tool to form the main body (10) having a lip (16) which is configured in a section at least close to the edge; demolding the main body (10); applying the material machining coating (18) to the end face of the main body that faces away from the lip (16); stacking main bodies (10) of the same kind, each having a material machining coating (18) applied thereto, so that the lip (16) of one main body (10) is directly supported on the material machining coating (18) of a next main body (10); exerting a pressure on the stack of main bodies (10), each of which has the material machining coating (18) applied thereto, parallel to the rotation axis of the main bodies (10); releasing the pressure and destacking the main bodies (10) which have the material machining coatings (18) applied thereto.
