CBN grinding wheel

摘要

PROBLEM TO BE SOLVED: To provide a CBN grinding wheel especially suitable for rough grinding.;SOLUTION: A CBN grinding particle included in the CBN grinding wheel 30 includes a single crystal CBN grinding particle 31 having a tetrahedron construction and a multi-crystal CBN grinding particle 32. Furthermore, the single crystal CBN grinding particle 31 is blended with a ratio equal to or more than 50% to the total summed volume of the single and multi CBN grinding particles, thus reducing grinding resistance and wear.;COPYRIGHT: (C)2012,JPO&INPIT
