G-Ratio - an overview | ScienceDirect TopicsTraduire cette page

High G ratios may be in excess of 5000 whereas for a difficult-to-grind material, the G ratio may be as low as 1. Dressing a grinding wheel causes a further loss of the abrasive layer. In the evaluation of the life of the wheel it is necessary to take this into account. A value of G = 1 is very low and implies that the abrasive is not hard enough for the task. A value G = 5000 is high and may ...
