CBN abrasive hardness higher than normal. High hardness means cutting stronger, sharper; CBN has a high abrasion resistance, meaning it harder than normal abrasive wear; ability to maintain the shape of the CBN abrasive as one of the main characteristics of high-performance abrasives; CBN's high compressive strength, which means that when used under harsh conditions it can remain intact and not broken particles; CBN has good thermal conductivity can be achieved when grinding cold cuts.

1, high hardness, high toughness
High hardness, high toughness cubic boron nitride (CBN) is a human synthesis of superhard material hardness only to diamond is much higher than ordinary corundum and silicon carbide abrasive, so it has a better cutting ability, sharper
2, high temperature, thermal stability
CBN can withstand 1250-1350 degrees Celsius, higher than 800 degrees Celsius heat resistance of diamond; during grinding and cutting ferrous materials, sticky crumbs phenomenon does not occur in the grinding hardened steel, high vanadium high speed steel, aluminum and other high-speed steel grinding temperature is more sensitive to the metal material is the best wheel.
3, the chemical inertness
CBN is not easy and the iron group elements produce a chemical reaction, so for a variety of high-speed steel, tool steel, tool steel, high alloy hardened steel, chrome steel, nickel alloys, powder metallurgy steels and high temperature alloys such as high temperature, high hardness grinding of materials of low thermal conductivity is very suitable.
4, good thermal conductivity
CBN grinding wheel corundum thermal conductivity up to several hundred times, and thus able to quickly export grinding heat, reduce the thermal deformation of the workpiece. The low thermal conductivity of the material is very suitable for grinding. Various spray (welding) Material: nickel-based, iron-based, etc.; cast iron type material: vanadium - titanium cast iron, high-phosphorus iron, chilled cast iron, etc.; titanium: such TC4 and so on.
