Results of the experimental studies on the quality of the grinding stones were reported. By means of a newly deviced testing apparatus, the quality of the grinding stones was compared with each other by measuring the dressing resistance under the working state with the square edged diamond dressor, which is proportional to the combined strength of the bond and the grain. And it was proposed that the grade of the grinding stone may be expressed numerically with the breakig combined strength by dressing under a certain condition. From numerous experiments on several kinds of grinding stones, it was cleared that their grade of the same nominal scale of different makers expressed usually with alphabet symbol, say J, K, L, M……, do not agree with each other, but the file of each mean value about their breaking combined strength by dressing shows the linear relation to that of so-called alphabet grade scale By this new testing apparatus, two components of the grinding resistance, tangential and radial could be measured using the test piece instead of the diamond dresser.
