In Grinding Coolant Application Matters

Mar 01, 2008 For superabrasive wheels, a flow rate close to 1 gpm/hp (3.8 L/min/hp) works well. This flow rate must be applied directly into the grinding zone, with additional flow rate for cleaning and flushing nozzles. The machine controller may be used to determine the approximate grinding power, or a phase-corrected power meter can be used.
