A killer combination for ideal grinding conditions

In fact, an ideal grinding condition (IGC) was observed with this combination. Ideal conditions are when the grinding efficiency remains unchanged (or in this case actually improves) with increasing metal removal rates (Q180;). It was previously considered impossible or contrary to scientific principles for this to occur in grinding operations.
