Schleif- oder Trennwerkzeug und Verfahren seiner Herstellung

The grinding and cutting tool consists of a fibre-reinforced base substance (3) composed of a plastic matrix and a coating (5, 7) made of diamond or borium nitride abrasive grain retained in a bond (7). In order to reinforce the bond between the basic substance (3) and the abrasive coating (5, 7) and to be able to use the tool as a high-speed tool, an intermediate layer (9) made of metal is applied galvanically or without any current onto the base substance in which electrically conductive fibres (19) projecting externally above the plastic and anchored in the pastic are embedded. These fibre sections (19) can be set free by resetting the plastic matrix of the base substance (3) before applying the intermediate layer (9). The intermediate layer (9) then covers the protruding fibres (19). Finally, the abrasive grain coating (5, 7) is applied to the intermediate layer (9).
