Refers to the fracture of grits and is important so as to expose new sharp edges. 4) Explain the relationship between grit size and surface finish? The smaller the grit size, the neater the finish. 5) Why is aluminum oxide used more frequently than silicon carbide as an abrasive?
WebOct 24, 2024 · Decreased sfpm will result in fewer cutting edges engaged per unit time of grinding, causing higher load on each individual grain. This results in increased friability of grains, causing premature wheel breakdown. As the wheel gets smaller, the sfpm stays constant, so the revolutions per minute (rpm) will increase.
