Industry-Leading CBN Wheels

It’s often said that diamond is the hardest material available to work with in the grinding industry and while that is true, but that only rings true under certain operating conditions. CBN, cubic boron nitride, is a man-made material with superior thermal stability and chemical makeup compared to diamond,  allowing it to maintain its hardness under much higher temperatures than diamond.

At around 700° Celsius, diamond suffers a massive loss of hardness.  CBN, on the other hand, remains unchanged at over 1,000° Celsius. This quality makes CBN superabrasives the ideal product for the ferrous tool industry.

Since diamond is pure carbon that is formed under pressure, it is not ideal for grinding steel and other ferrous materials. 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 is not made up of carbon, just boron and nitride, making it the ideal superabrasive for grinding steel, Stellite and nickel-based alloys. If you would like to read more about CBN wheels, CLICK HERE.
