Another factor that affects the choice of wheel bond is the wheel speed in operation. Usually vitrified wheels are used at speeds less than 6,500 surface feet per minute. At higher speeds, the vitrified bond may break. Organic bond wheels are generally the choice between 6,500 and 9,500 surface feet per minute.

For example, a grinding wheel moving at 12,000 sfm (3,657 m/min.) requires a nozzle pressure close to 270 psi (18.6 bar) for the coolant jet to match the wheel speed. Lower wheel speeds require lower pressures. The chart (below) shows the pressure required for water-based, synthetic oil and mineral oil coolants to achieve the desired jet …

Figure 2. 1 Power (P) is equal to the product of torque (T) and rotational speed (n): P = T x n. Torque is oficially expressed in Newton x meters (Nm). The oficial SI-unit for rotational speed is radians per second (rad/s). In grinding the accepted term is, however, revolutions per minute (rpm).
