CBN Wheel is Industry Leading

How do you compete against the hardest material known to man? Easy: create an entirely new material that’s even harder under extreme temperatures than diamond. It’s often said that diamond is the hardest material available to work with in the grinding industry and while that is true, but only under certain operating conditions. Modern science has created an even harder material under high temperatures that changed the grinding wheel industry. cBN named after its cubic form of boron nitride is enhancing the grinding wheel experience. cBN has a superior thermal stability and chemical makeup than that of diamond, making it the ideal product for the ferrous tool industry.


The thermal stability of CBN is fairly significant compared to that of diamond. At around 700 degrees Celsius, diamond suffers a massive loss of hardness whereas CBN goes unchanged at over 1,000 degrees Celsius.


Using a CBN wheel to grind steel over diamond is another big advantage. Since diamond is pure carbon that is formed under pressure, it is not ideal for grinding steel. The high thermal temperatures that are caused while grinding cause the steel to take in the carbon atoms from the diamond wheel and result in eroding the diamond grit. cBN isn’t made up of carbon, just boron and nitride making it the ideal super abrasive for grinding steel, Stellite and nickel based alloys.
