Abstract (en)

[origin: WO9729886A1] The invention concerns a grinding tool for machining in particular brittle-hard materials. The bond in the grinder members of the tool is brought about by two components, one component consisting of synthetic resin, such as for example high-temperature thermoplastics or pressure sintered polymer, and a second component consisting of sintered metal with a low melting point. The processing temperature of the two components when they are jointly pressure sintered is the same. The essence of the invention lies in designing the two different binders such that they each have their own cohesive network and their mutual spatial interlacement in the grinding member forms an interpenetrating network. The invention further concerns a method of producing grinding members for grinder tools. The invention combines the advantage of greater binding forces of the metal bond with the advantage of higher elasticity of the synthetic resin bond in a grinding tool.
