2, Rotary dresser for the Vitrified bond CBN wheels.

The primary characteristics of Vitrified CBN grinding wheel are high hardness, high thermal conductivity, high sharpness, resulting in high grinding efficiency. Suitable for high efficiency grinding of steel.
Because CBN material is hard so it is very difficult to dressing, Then special diamond rollers are needed.
