CBN H200 type has been produced for more than 15 years according to classical technology of synthesis of cubic boron nitride. These are monocrystals and their splices of semi-blocky shape, predominantly of black color, with inclusions of dark-gray grains. Owing their mosaic-sectored crystal structure the edges of crystals have advanced microrelief. High fragility morphologically predetermines self-sharpening of cutting edges of crystal due to breaking away of small fragments. Owing to advanced surface of edges, CBN H200 crystals well knit with ceramic and other kinds of bonds, which ensures firm retention of grains while the tool is at work.
CBN H200 performs well in ceramic or galvanic bond under medium power of grinding. With 60% nickel coating CBN H200 60N is successfully used for manufacturing tool on resin bond, as well as for grinding, finishing, honing of high-speed steels, alloys and cast iron >40 HRc.
