Abstract: A supporting body for a grinding tool, the supporting body including an abrasive pad having a preferably circumferential supporting surface for an abrasive material, particularly a superabrasive material. The supporting body consisting substantially of a composite material which is free of abrasive material and consists of a plurality of layers of a natural fiber material which are arranged one atop the other and are connected to each other by plastic, preferably phenolic resin. The natural fiber material preferably is a cotton fabric or paper, and the supporting body includes a first, preferably cylindrical or hollow cylindrical body and at least one additional, preferably cylindrical or hollow cylindrical body, in which the bodies are connected, preferably adhesively bonded, to each other.

Abstract: A surface of a workpiece is treated by rotating about an axis a brush having a multiplicity of radially projecting bristles with tips engaging a surface of a workpiece to be treated while positioning a stop nonrotatable with the brush in engagement with the bristles radially inward of the stop so as to rearwardly deflect the bristles prior to contact with the workpiece and thereby store kinetic energy in the bristles so that as the bristles pass the stop the kinetic energy is released and the bristles spring elastically forward and percussively strike the workpiece surface. A roughness of the workpiece surface is determined and the stop is positioned radially relative to the axis or the brush is positioned relative to the workpiece at a spacing in accordance with the determined roughness.

Abstract: There is described a grinding wheel (1), particularly for grinding operations carried out on sheets of glass (2), ceramic material or similar materials, comprising a disc-shaped support with abrasive material arranged on the circumferential profile of the support, and an opposing central hole (3) for attachment to a drive shaft (4) of the grinding wheel. The disc-shaped support comprises a pair of opposed disc-shaped grinding wheel bodies (5, 6) coupled in a facing position so as to define together the abrasive grinding surface (5c, 6c) along the circumferential profile, and each of the disc-shaped bodies (5, 6) has a predetermined resilience such that the disc-shaped bodies (5, 6) can be flexed away from each other in the zone of contact with the component being ground, for the purpose of consequently applying pressure to the component in the grinding operation.
