Diamond rotary dresser for crankshaft grinding wheel
1. Rotary dresser for the WA/PA wheels.
Dressing with rotating diamond tools has been found to be a reliable technique in series and performance grinding processes, especially those applications using vitrified bonded grinding wheels.
The automotive and -supply industry for grinding crankshafts.

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.
