The problem of the effectiveness of processing synthetic super hard materials remains to this day very relevant. In order to increase the robustness of diamond circles, the task was to find the optimal combination of grades, grains, concentrations of diamond powders with the type of metal bond, which ensure the minimum defect of sintered grinding wheels (in terms of determining the conditions for maximum preservation of the integrity of the grains). In this paper, the method of determining the dynamic strength of grains of the diamond-bearing layer of grinding wheels is given in order to select the optimal composition of the bond and increase the effectiveness of diamond grinding.
