CHAPTER 3- MECHANICS OF GRINDING
high speed grinding of metals have shown beyond doubt that much higher grinding ratios are achievable. At higher speeds, the normal force between the wheel and surface decreases, thus diminishing the probability of fracture of grains. Research in high speed grinding has shown that grinding ration as high as 4000 are achievable.
