Effect of grinding wheel balance

•Cutting resistance becomes steady by balancing grinding wheel
•Surface roughness can be improved by steady cutting resistance.
•Life time of grinding wheel can be extended because of uneven wear is prevented by balancing.

High accuracy and efficient

•Resolution: 0.001μm
•Measures grinding wheel during rotating on grinding machine. So, possible to perform unbalance correction of the whole of grinding wheel including spindle. It causes long life and maintain high accuracy of grinding machines.
