Boron Nitride Abrasive Tool

Because ceramic bond is used, compared with resin bond, ceramic bond boron nitride abrasive tools have obvious advantages in shape retention, high temperature resistance, machining accuracy and surface finish of workpieces. Compared with ordinary abrasive ceramic abrasives, the service life of boron nitride ceramic bonded abrasives can be increased by 20-200 times, and the processed materials have high hardness and high work efficiency. It is very suitable for high-precision and high hardness processing. Ceramic bonded boron nitride abrasive tool has the advantages of certain elastic modulus, small coefficient of thermal expansion and good toughness. It is a new type of superhard abrasive tool recently developed. The common particle sizes are 80, 100, 150, 180, 220, 320, 400, 500, 600, 800, 1000, etc. it can also produce ultra coarse particle sizes such as 30, 46 and 60 and ultra fine particle products such as 1200, 1500 and 2000.

Because the ceramic bond has the above unique properties, the ceramic bond boron nitride has the advantages of sharp cutting, high working efficiency and good grinding wheel angle when in use on the premise of ensuring high strength and wear resistance. Now, ceramic bonded Boron Nitride Abrasives are more suitable for the processing of hard grinding materials with high hardness, such as high-speed steel, nickel chromium alloy, temperature resistant alloy, stainless steel, ferroalloy, bearing steel, chilled cast iron, chromium alloy, cemented carbide and titanium alloy. They are widely used in PCD superhard cutting tools, universal joints, nozzle oil pumps, automobile engine manufacturing, molds, air conditioning compressors, gears Manufacturing of aircraft engine, processing of coupling and hydraulic tappet. Due to the excellent performance of boron nitride ceramic bonded abrasives, it has a very broad prospect for modern enterprises that pay attention to work efficiency.
