  • Patent number: 9211631
    Abstract: The present invention relates to a grinding wheel truing tool, its manufacturing method, and a truing apparatus, a method for manufacturing a grinding wheel and a wafer edge grinding apparatus using the same. The grinding wheel truing tool of the present invention compensates a groove of a fine-grinding wheel for fine-grinding a wafer edge, and includes a truer having an edge of the same angle as a slanted surface of the groove of the fine-grinding wheel and a cross-sectional shape corresponding to a cross-sectional shape of the groove. The present invention uses the truing tool to easily process the groove of the grinding wheel for fine-grinding the wafer edge.
