Abstract

The invention discloses a heat-resistant anti-impact grinding wheel material. The heat-resistant anti-impact grinding wheel material is prepared from diamond, silicon carbide whiskers, aluminum borate whiskers, potassium titanate whiskers, aluminum oxide whiskers, yttrium oxide, cerium oxide, feldspar, fluorite, modified phenolic resin, polyurethane resin, polyethylene wax emulsion, calcium lignosulphonate, slag, glass fibers, carbon fibers, a pore forming agent and alloy powder. The heat-resistant anti-impact grinding wheel material is reasonable in composition. An obtained grinding wheel is excellent in bending strength, microhardness, impact toughness, wear resistance, heat dissipation performance and heat resistance, not likely to burst apart and high in safety coefficient and meanwhile has the beneficial effects of being high in grinding efficiency and grinding ratio, good in grinding quality, long in service life and the like. Good economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of grinding wheel materials, in particular to a heat-resistant and impact-resistant grinding wheel material. Background technique [0002] Grinding wheel is a circular solidified mold with a through hole in the center made of abrasives and bonding agents. It is the most widely used abrasive tool and is suitable for processing various metal and non-metal materials. Grinding wheels can generally be divided into vitrified bonded grinding wheels, rubber bonded grinding wheels and resin bonded grinding wheels according to different bonding agents. Among them, the resin-bonded grinding wheel is made of resin as a bonding agent and abrasives. With the continuous development of the polymer material industry, the development of resin-bonded grinding wheels is rapid. Resin-bonded grinding wheels are often used in the grinding process. Cutting, fine grinding, etc., have a wide range of applications and become an irrep...
