CBN Wheel Composition

CBN stands for cubic boron nitride, a man-made material that is specialized to cut hard-to-grind ferrous materials. Diamond wheels are great for carbides, glass and ceramics, but they don’t tolerate heat well. As we all know from experience, grinding at high speeds causes heat to build up at the point of contact, resulting in the breakdown of the wheel. CBN wheels have a very high thermal conductivity rate, allowing them to withstand the demanding heat that is generated when grinding ferrous materials, including many varieties of steel. 


CBN Wheels and their Crystal Structure 

A CBN crystal structure nearly matches diamond atomically, but their bonding differs. Carbon atoms hold the structure of diamond, while boron replaces these atoms in CBN. This small replacement of atoms is results in the difference in thermal conductivity, allowing CBN wheels to efficiently grind ferrous materials.
