Результаты исследований по разработке способов изготовления шлифпорошков из синтетических алмазов однородного зернового состава с повышенными абразивными свойствами и прочностью

Abstract

The methods and technological scheme of production of special grinding powders (AC6 and AC15) of demand grit sizes are presented in this article. These powders possess high strength and high abrasive properties in combination with high content of main fraction as well as high uniformity of grit composition. Optimal operating regimes for non-standard equipment have been are chosen, sieves with narrow module (m = 1.189) have been applied. According to suggested technology the initial product to produce grinding powders is concentrated product of diamond synthesis as well as composite compacts from undersize particles including ultradispersed diamond (UDD). The diamond grinding powders produced according to this technological scheme are recommended to produce numerous nomenclature of grinding and polishing tools including single-layer tools.
