Перспективы изготовления прецизионных шлифпорошков кубонита с высоким содержанием основной фракции и однородностью свойств

Abstract

The results of studies for development of production process of precision grinding powders from cBN with grit size and strength uniformity and high content of main fraction are presented. Advanced scheme of processing of concentrated synthesis product of cBN developed on the basis of non-standard equipment (designed by ISM NASU) is shown. Equipment succession consists of the following devices: universal rotor impactor of continuous operation, pneumatic and vibration classifiers with sieves of narrow module and round opening for separation of grits by form. Grinding powders of 200/160, 160/125, 125/100, 100/80, 80/50 grit sizes produced by this technology are recommend for production of numerous nomenclature of instrument assigned for lapping and precise finishing of steels and Fe-based alloys including tool steels.
