The 7 Factors Used to Determine a Grinding Wheel …

For easy to grind materials, we would want a coarser grit. This is because the grain can easily penetrate the material, make and remove chips. Using a larger or coarser grit maximizes the stock removal, reducing cycle time. Another aspect of the wheel we can dial in on based on the material being ground is the grade or hardness of the bond.
