Factors affecting proper coolant application when grinding

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 speed.
