Grinding Ratio for Evaluating Grinding Wheel Performance

The length ac (δx) represents the volume of metal removed and the length be (δy) represents the volume of wear of tool and so the grinding ratio will be as follows: Volume of metal removed / Volume of wear of tool = δx / δy ADVERTISEMENTS: The grinding ratio normally varies from 75 to 125. The greater the grinding ratio the better wheel is.
