CBN Wheel Composition

CBN wheels are the ideal product for grinding ferrous metals, including various types of steel.  CBN stands for cubic boron nitride, a man-made material that is only rivaled by diamond. However, CBN holds certain advantages over diamond in specific applications.

Diamond wheels are great for carbides, glass and ceramics, but they don’t resist heat well. Grinding at high speeds causes large amounts of friction, resulting in heat buildup at the point of contact. This ultimately results in the breakdown of the wheel. CBN has a very high thermal conductivity rate, allowing it to sharpen and grind ferrous metals that normally glaze up diamond wheels due to the extreme temperatures generated.

Atomically, CBN crystal structures are nearly identical to diamond. The difference exists in the bonding match.  In diamond, carbon atoms hold the structure.  With CBN, boron holds the structure instead. This seemingly insignificant change of atoms fuels the difference in thermal conductivity, allowing CBN wheels to grind ferrous materials much more effectively than diamond wheels can.
