  • Nano finish grinding of brittle materials using ...

    prevents excessive flow out of the bonding material from the wheel. As grinding begins (d), diamond grains wear out and the layer also becomes worn out (e). As a result, the electrical conductivity of the wheel surface increases and the electrolytic dressing restarts with the flow out of bonding material from grinding .
