Purchase of 18R-40 diameter of 100 mm
Purpose of profile wheels: Profile wheel _ a tool used in the profile grinding operation for rounding the edge of the PMC along the generatrix, on the base cut and additional cuts; Recalibration by diameter to the nominal value during multiple rolling of the PMC (elimination of ellipsoidality after oriented cutting of ingots into plates, formation of a diameter with a maximum deviation of ±0.2 mm); Formation of the chamfer texture. The geometric dimensions of the chamfer are provided by the tool. The surface texture of the chamfer is a shiny narrow strip, on the surface of which there should be no bumps, chips, scratches (at 20X magnification). The edge of the chamfer should be wavy without nicks. It is used to provide the edge profile and chamfer texture of a monocrystalline silicon plate in accordance with the requirements of technical regulatory legal acts.:
The profile circle is a metal disk with one profile canard at the end for the nominal thickness of the PMC with an angle and radius of rounding that ensure the formation of the PMC edge, and a layer of diamond micro-grinding powder with a grain size of 20-28 mm.
