INTEGRATED GRINDING WHEEL AND GRINDING DEVICE USING THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an integrated grinding wheel capable of reducing the cost by extending a working service life compared to a conventional grinding wheel employing a single crystalline diamond for a grinding grain and capable of improving processing accuracy (appearance) and product ratio while capable of grinding and processing a workpiece made of a hard material such as a glass lens. SOLUTION: This integrated grinding wheel 1 is provided with a grinding surface 13 made by binding and holding a grinding grain 11 with a binder 12 in a shape that a part or a whole of a target finishing surface of the workpiece 30 as the grinding object is reversely copied to a part of an outer surface thereof. The grinding grain 11 is constituted by polycristalline diamond or CBN.
