The article presents one of the options for developing scientifically based recommendations for choosing a rational combination of the strength of the binder, the size of the diamond grain, the concentration of diamond grains with the physical and mechanical properties of different types of binders in the manufacture of diamond grinding wheels. The conducted studies have shown the feasibility of using detonation nanodiamond powders as a modifier of the polymer binder. The introduction of nanopowder into the polymer leads to an increase in microhardness by 23%, and the recommended mass fraction of nanodiamond should be about 1% of the weight of the binder. It is possible to use such polymer compositions in the diamond layer of standard grades, which theoretically will increase their hardness due to constant thermal conductivity.
