2011-1-13 Since the last two decades, there has been an increased interest in the investigation of grinding processes. Grinding is the most common form of abrasive machining. It is a material cutting process which engages an abrasive tool whose cutting elements are grains of abrasive material known as grit. These grits are characterized by sharp cutting points, high hot hardness, and chemical stability

2021-1-29 The answer has to do with depths of cut. “When you turn or grind a part, the depths of cut could range from 50-100 microns or higher,” Keshavan says. “Removing that amount of material in a short amount of time requires lot of energy, and the part heats up. Superfinishing removes 1-2 microns of stock on radius and requires less energy.”.
