2021-12-6 · The main movement speed υc (m/s) is the linear velocity of the outer circle of the grinding wheel, that is, υc=πd0n0/1000. In the formula, d0 is the diameter of the grinding wheel (mm); n0 is the speed of the grinding wheel (r/s). In ordinary grinding, the main motion speed υc is 3035m/s; when υc>45m/s, it is called high-speed grinding. 2.
