  • GRINDING TOOL FOR MACHINING BRITTLE MATERIALS AND A METHOD OF MAKING A GRINDING TOOL
    Publication number: 20140227952
    Abstract: The invention relates to a grinding tool for machining brittle materials. The grinding tool has a core and an abrasive rim. The abrasive rim has abrasive particles embedded in a matrix. The matrix has a metallic bonding agent and possibly also a polymeric bonding agent. The metallic bonding agent contains silicon nitride in an amount that constitutes 0.02%-5.0% by volume of the metallic bonding agent. The invention also relates to a method of manufacturing the grinding tool. In the method, abrasive particles are mixed with metal powder and silicon nitride and the mixture is sintered. Polymeric powder may also be added before sintering.
