This paper describes the characteristic and the mechanism of the abrasive wear of the super abrasive grinding wheel. The characteristics have been obtained on the lapping equipment by the wear experiment, using the sticks of resinoid diamond stones equal to the composition of abrasive grain layer in the super abrasive grinding wheel. The following results are obtained: the rapid abrasive wear of diamond grinding stone occurs at the pressure above the abrasive grain holding force because of ploughing the bond by the diamond grain, on the other hand, the matrix abrasion occurs slowly at the pressure below it. The influence of the grain size and concentration on the abrasive wear are clarified also. In the selection of the truing, dressing and grinding condition, the experimental results will be useful.
