PROBLEM TO BE SOLVED: To provide machining abrasive grains capable of efficiently machining even a hard workpiece. SOLUTION: The machining abrasive grains are constituted of mixed abrasive grains mixing at least main particles made of diamond and sub particles made of sialon particles. Therefore, while suppressing the use amount of expensive diamond particles, a machining property which is vastly superior to a conventional one can be obtained. COPYRIGHT: (C)2011,JPO&INPIT |
