Abstract:
A machine tool, for example a hand-held belt grinder, is subjected to high frequencies outside a working plane between an abrasive belt and a workpiece. In particular, the machine tool is subject to high frequencies in a free-running region of the belt, of an excitation actuator, in particular by a piezo element.
Abstract:
A method for producing a coated abrasive includes producing or providing an intermediate abrasive product that comprises a substrate, a plurality of abrasive grains that are bonded to the substrate, and at least one layer of an uncured size coat that at least partially covers the abrasive grains with the uppermost size coat being uncured. The method further includes applying at least one grinding additive to the uppermost, uncured size coat with the grinding additive applied to the size coat in dry form. The method also includes curing the uppermost size coat. A coated abrasive is produced by the method and the coated abrasive is used to process a surface.

Abstract:
The present invention relates to a novel grinding tool, comprising a substrate with a first water-permeable, flexible textile layer, which comprises multifilaments and to which the abrasive material has been applied, and at least one second layer, which is connected to the surface of the first layer that is free from abrasive material, can absorb water and can be compressed, the abrasive material made up of binder and abrasive grain, selected from the group comprising diamond and cubic boron nitride, being applied to the first layer in such an amount that the grinding tool has a service life of at least two minutes, preferably at least 10 and with particular preference at least 20 minutes, when working a ceramic coating surface by wet grinding.
