  • Patent number: 5637388
    Abstract: A composite resinold/graphite/diamond blade is described having enhanced precision cutting properties. The blade is made by assembling several layers, each layer comprising a veil of non-woven graphite fabric impregnated with a mixture of diamond particles blended into a phenolic resin. Layers are built up in sandwich fashion. In one embodiment described, four layers are formed and, in a heating compression molding operation, the sandwich is compressed into a composite blade having a diameter of 4.7 inches with a thickness of 0.011 inch. The final blade is formed by a die cut and lapping process. The layered construction yields a blade with more consistent cross-section and improves blade wear symmetry. In another embodiment, the layers are tailored to have a grit concentration of the diamond/resin mixture at the periphery or cutting edge.
