It is recognized that CBN (cubic boron nitride) is second only to diamond in hardness, two times that of diamond in high temperature resistance, four times that of traditional abrasive in wear resistance, and have extraordinary thermal conductivity. There are hundreds of raw materials needed to use CBN to grind in present manufacturing market, from aerospace superalloys and thermal spraying to the hardened steel in automotive bearing and gear industry to improve efficiency and get the shortest processing time. Components and spare parts can get better quality by CBN grinding. Products are optimized to prevent thermal damage during the finishing process. At the same time, the quality consistency of the machined parts is improved. These machining technologies make full use of CBN advantages of increase grinding wheel life and wear reduction. So that the expensive machine can run longer time between the grinding tool replacements and reduce the adjustment time during operation to better meet the requirement of modern automated machine and improve productivity and work efficiency.

resin bond vitrified bond metal bond electroplating tool
Adopting mature electroplating technology, abrasive is plated with different proportion of nickel, which can effectively improve grinding wheel life.
Adopting the mature chemical processing technology, the abrasive is treated with weight increase and nickel coating, which greatly enhances the holding force and heat dissipation ability between the grains and improves the surface finish of the workpiece.
"T" refers to product with titanium-coated surface, and mainly applicable for metal and vitrified bond system. After titanium coating, it can protect the abrasive performance to get higher thermal resistance, and effectively improve the life of the grinding wheel.
resin bond vitrified bond metal bond electroplating toolLight green, polycrystalline, rough surface, irregular shape, easy fragile, combination of grinding efficiency with service life, and used in the long life and efficient grinding of gemstone, vitrified, glass and carbide tool.
Light green, micropowder, good self-sharpness, and used in high-precision and high-efficiency grinding of ceramic and glass.
Adopting chemical processing technology, abrasive is claded with nickel coating, which greatly enhances the holding force and heat dissipation ability between the grains and improves the service life of the grinding wheel.
