The way of  problem solving

 The prototypes of Kiborit 1 and Kiborit 2 are the materials AMB90 (Element Six) and MN-100 (Megadaymond), that are intended for the most severe operating conditions, contain 90 or more of weight percent of CBN, and the CBN fine grains of 8 - 10 microns in size. Such materials are obtained by sintering at high pressures and high temperatures in a form of single-layer plates (without a bottom layer). A binding of such materials contains the high-melting compounds of aluminum, that indicate the sintering of charge with aluminum or its alloys. The materials have high hardness, fracture strength and thermal conductivity. They are not electrically conductive and their cutting is carried out by the laser.
