The line speed of the grinding wheel is generally 30~60m/s, the CBN grinding wheel can be as high as 150~200m/s, and the highest spindle speed is 15000r/min. The spindle unit is the pivotal component of the grinding machine. There are some drawbacks to CBN wheels, the first being expense. The typical 6″ or 8″ wheel costs between $150 and $250. The other drawback is that they will only grind hardened tool steel: mild steel will ruin them. They really work best on high-speed steel but will do fine on carbon tool steel that is Rockwell C scale 55 or above. I feel Superabrasive diamond grinding wheels for CNC tool grinder.
