Abstract

The grinding characteristics of optical glasses with respect to two kinds of diamond pellet (A-D.P and B-D.P) and investigated by comparing the experimental values of grinding hardness with those of volume loss. A-D.P and B-D.P, the products of two different companies, are different in their composition of bond, but they have equal diamond concentration and equal grain size. Sample glasses used are BK, SK, BaF, F, SF, LaK, LaF, and LaSF. As the result of investigation, a method to qualitatively represent the grinding characteristics with respect to D.P is proposed.<BR>The relation between physical properties (the abrasion hardness with respect to loose grain, Knoop Hardness, and Young's modulus) and the grinding hardness is also examined.
