Jan 07, 2019 In the grinding process, if the concentration is higher, the smaller average load on one abrasive grain. Therefore, the wear of abrasive grains becomes slower and the grinding ratio increases. However, for diamond grinding wheels, the reasonable combination of grain size, concentration and bond can achieve the good grinding effect. 5. Bond effect

Oct 31, 1998 In this equation, G is the grinding ratio, which is defined as the volume of material removed per unit volume of wheel wear. G increases with less wheel wear and/or higher metal removal. The higher it is, the better the grinding conditions, especially in terms of longer wheel life. To determine G, one takes the equation: G = Vw/Vs
