What is grinding ratio (G)
· The grinding ratio is defined as the ratio of the volume of material required to the volume of wheel wear G = (the volume of material required) / (the volume of wheel wear) The value of grinding ratio is usually about 10 to 60 for fine grinding operations like horizontal surface grinding.
