CBN stands for cubic boron nitride. It is an abrasive material that rivals the hardness of diamond and out performs diamond when grinding certain materials. While diamond has held the spotlight for many years as the industries superior choice of superabrasive, CBN wheels are the ultimate wheels for grinding materials such as hardened steel or other ferrous metals.
Effect of CBN Wheels Grit Size on Surface Finish
CBN is great for grinding most grades of steels, but they must have a hardness of 45Rc or above to be ground effectively with CBN.
Hardened stainless steels have been found to be ground effectively and profitably with CBN resin bond wheels.
Unlike diamond, CBN wheels do not react to iron, so ferrous materials are not a problem when using CBN.
