RESEARCH GROUP OF DIAMOND TOOLSMain direction of research works is diamond composites (DC) Developed are diamond composites and the technology of production on their base diamond bars like АПС and milling cutters with the diameter 95mm to grind the plates from building materials and natural stones; cut circular saws of a segmental shape with a continuous edge for cutting natural stone (granite, marble, building materials (concrete, ferroconcrete, mosaic plates, etc.), as well as road coatings; diamond abrasive wheels for treating industrial glass, mirror, natural stone, ferrites, ceramics and other materials Diamond composites have a coarse-heterogeneous structure where diamond particles are "rolled up" in a hard alloyed jacket with a thickness that is comparable to particle size that permits to increase the cutability of diamond composite tools while treating ferroconcrete, when diamond grain can fail when meeting reinforcements. |

Developed is a universal bundle "copper-tin-nickel-tungsten carbide" that is used to produce diamond tools to cut building materials and rocks. A new field of using of diamond tools is highway engineering with a wide introduction of means of a small-scale mechanization with a diamond tool instead of impact pneumatic tool such as tools for cutting concrete seams and different kinds of plates including facing tiles.
The increase of wear resistance of this new material is due to an increase of the content of nickel and tin, to an introduction of a supplementary abrasive, as particles of a cast tungsten carbide, and to a cladding of diamond powders by metals. There is possible to use both natural and synthetic diamonds in a composition. The new material provides an operation resistance and productivity conforming to the best foreign analogues but significantly cheaper. This material found application in glass treating shaped tools such as wheels of an angular and radius profile; cut segmental wheels with a continuous edge, segments and skelps.
