As a result of the studies carried out, the influence of the structural components of the new diamond-containing mineral-ceramic material on its working properties was evaluated. The volumetric cutting ability of a diamond-containing tool, which is stable in the process of abrasive wear, increases nonlinearly with an increase in the grain size of diamonds and slightly decreases with an increase in their concentration. The morphology of the working surface of the abrasive tool practically does not change during operation. It has been established that the roughness of the treated surface increases when using diamonds of larger fractions. With an increase in the concentration of diamonds in a tool made of a mineral-ceramic material, the parameter of the surface profile Ra of the workpiece does not decrease linearly. An empirical dependence of the parameter Ra of the treated surface is proposed. It has been established that abrasive tools made of diamond-containing mineral-ceramic material in the process of operation realize the mode of self-sharpening.
