Why do more and more people choose CBN grinding wheel

With the refinement of materials to be grinding, various grinding wheels are constantly updated. Traditional corundum grinding wheels and diamond grinding wheels are not enough to meet all grinding requirements.

Now on the market many people choose CBN (cubic boron nitride) grinding wheel, but more people do not know what is CBN grinding wheel, also do not know what benefits of CBN grinding wheel.

CBN (cubic boron nitride) is human synthetic, second only to diamond hardness, much higher than ordinary corundum and silicon carbide abrasive superhard material. Many people who come into contact with it for the first time will equate it directly with diamond,

In fact, this is a misunderstanding. Compared with diamond, CBN still has many advantages compared with diamond. Firstly, CBN has the characteristics of high temperature resistance and good thermal stability. CBN can withstand temperatures between 1,250 and 1,350 degrees Celsius,

Higher than the heat resistance of diamond 800 degrees Celsius. When grinding and cutting iron materials, there will be no sticky chip phenomenon, is honed hardened steel, high vanadium high speed steel, aluminum high speed steel and other metals sensitive to grinding temperature

The most ideal material for grinding wheels. Secondly, CBN grinding wheel has strong chemical inertness, and cubic boron nitride is not easy to produce chemical reaction with iron group elements, so it can replace diamond.

Grinding tool steel, high alloy hardened steel, chromium steel, nickel alloy, powder metallurgy steel and superalloy and other high temperature, high hardness, low thermal conductivity of the material is very suitable. So, in processing these iron group materials,

The durability is 3-5 times higher than diamond grinding wheel. If conditions permit, CBN grinding wheel can be used instead of ordinary grinding wheel to grind hard steel, especially grinding high-speed tool steel, the cost is lower, more cost-effective use.
