These materials are broken into very small grains and adhered to the wheel with a bond. As you use the grinding wheel, small pieces of the granules chip off. This chipping effect keeps the grinding face of your wheel continually sharp. CBN Grinding Wheels A CBN grinding wheel uses Cubic Boron Nitride, or CBN, as its grinding material.

I use a flow rate based upon the grinding power created during the process, because the more aggressive a cycle is, the more coolant is applied. With conventional abrasive wheels, a flow rate of 2 gpm/hp is effective. For superabrasive wheels, a flow rate close to 1 gpm/hp (3.8 L/min/hp) works well.
