ОБРАБОТКА МЕТАЛЛОВ № 1 (74) 2017 37 ОБОРУДОВАНИЕ. ИНСТРУМЕНТЫ it is important to know which diamond crystals, with some internal and surface defects are for the manufacture of modern grinding tools. 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 the analysis obtained through scanning electron microscopy images shows that even on the surface not involved in the process of cutting the diamond grains and on their edges, there are characteristic traces disorders of the crystal structure, both micro and macro levels. 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. Keywords combined electro-diamond grinding, synthetic diamond, adhesion contact, computer simulation, molecular dynamics. DOI: 10.17212/1994-6309-2017-1-30-39 References 1.
