Ceramic bonded grinding tools with graphite in the bond

摘要: Ceramic bonded grinding and honing tools employing diamond or cubic boron nitride abrasive particles are improved by the inclusion of from 10 to 53%, volume, graphite in bond, based on total bond solids, including graphite. The must have a porosity volume less than 15% for applications 10% wheels, preferably should be finely particulate. Applications dry hard materials described. For optimum content is 34 45 percent. may include crystalline filler such as alumina, zirconia, silicon carbide, formed situ devitrification; metal coated. MoS 2 hexagonal substitute all part powders employed replace up 50% materials.
