CBN GRINDING WHEEL 11A2 1A1
Process characteristics of CBN grinding wheel
CBN has a higher hardness than ordinary abrasives. High hardness means stronger cutting ability and sharper; CBN has higher wear resistance, which means it is more difficult to wear than ordinary abrasives; the ability to maintain the shape of abrasive grains is one of the main characteristics of CBN as a high-performance abrasive; CBN High compressive strength means that it maintains particle integrity and is not easily broken when used under harsh conditions; CBN has good thermal conductivity and can be cold cut during grinding.
1, high hardness, high toughness
High hardness, high toughness Cubic boron nitride (CBN) is a harder material that is second only to diamonds synthesized by humans. It is much higher than ordinary corundum and silicon carbide abrasives, so it has better cutting ability and sharper.
2, high temperature resistance, good thermal stability
Cubic boron nitride can withstand high temperatures of 1250-1350 degrees Celsius, which is higher than the heat resistance of diamonds of 800 degrees Celsius; when grinding and cutting iron materials, there will be no sticking phenomenon, grinding hardened steel, high vanadium high speed Metal materials such as steel and aluminum high-speed steel that are sensitive to grinding temperatures are the most ideal grinding wheels.
3, strong chemical inertia
Cubic boron nitride is not easy to react with iron group elements, so it has high temperature and high hardness for various high speed steel, tool steel, die steel, high alloy hardened steel, chrome steel, nickel alloy, powder metallurgy steel and high temperature alloy. Grinding of materials with low thermal conductivity is very suitable.
1A1 Flat-shpaed Resin Bond CBN Diamond Grinding Wheels
Resin Bond is the most common choice in Diamond and CBN super-abrasive wheels. It forms a bond structure that keep the wheel sharp cutting, super surface finish, efficient grinding and less heat generating. The most important is that it is very cost effective. It is more competitive than Vitrified bond and Metal Bond. So it is broadly applied in the grinding industries.
