Abstract
Defects arising in diamond crystals during their synthesis, give rise to the formation of more complex defects that arise in the operational process of diamonds themselves. In case of external action these defects have immediate strong effect on operating characteristics of devices, products or tools containing diamonds. When external action these defects and have immediate strong effect on production characteristics of devices, products or instruments containing diamonds. This is particularly manifested in the grinding of tough, ductile materials based on aluminum, magnesium or titanium. Developed on the basis of modern digital technology and molecular dynamics visualization method allows to show it at the atomic level. The problems of practical application of the combined electric diamond grinding are examined. Experiments were conducted on the grinding tool materials with metal-bonded diamond grinding wheels.

Summary
The basic parameter which identifies quantitative, qualitative and price characteristics of engineering projects of the time is a possibility to carry out a virtual experiment. In order to expand the mechanism of adhesion, it is necessary to carry out comprehensive analyses in terms of material science, mechanical engineering technology, chemistry and solid-state physics by atomic visualization of juvenile surfaces [19, 20] To this effect it is necessary to take into account the specific character of artificial diamond synthesis, which was practically neglected by previous researchers. There is evidence that adhesion of grinded off material to the grinding wheel bond, or so to say loading itself, mostly occurs due to some defects of crystal surfaces As a rule, they are represented in the form of crystal lattice blocks (Fig. 1, d). Threedimensional defects as well as point ones can be located on the crystal surface and inside diamond grains, diamond crystal fracture directly depends upon an external cutting force and heat process. Nano-sized voidites can be of length from one nanometer (Fig. 1, h) to a few micrometers (Fig. 1, i) and located between grains of a similar orientation at their boundaries or along dislocation lines [19, 22]
