Gear hobbing cutter is high-speed steel material
So we choose resin bonded CBN grinding wheel.
The first step is to use GC dressing wheel to repair this CBN wheel
To make sure the concentricity is good,
Then grind gear hobbing blade.
During grinding, if you find the CBN wheel you are using is a little bit hard, you should slow down the line speed from 40m/s to 30m/s.
The roughness and sharpness are the most important for the CBN wheels.
