These grinding wheels use CBN or aluminum oxide as abrasive grains for all kinds of gear teeth grinding like gear rack,gear hob cutter,screw gear,worm gear,cylindrical gear and so on.
Worm grinding wheel for gear
The worm grinding wheel is mainly used for grinding the worm gear and worm gear surface of the reducer.
The product has good stability, high grinding accuracy and small cumulative pitch error.
It can maintain continuous involute and helical gear geometry. It has good transmission stability and low transmission noise.
So it is widely used for grinding of small and medium size gear. Especially the grinding of mass gear.
Resin bond CBN grinding wheel for gear hob cutter
This type of CBN grinding wheels are specially used for gear hob cutter grinding,
before grinding, we need to use Green silicon carbide grinding wheel dress it, to make sure it has good concentricity.
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.
