Abstract: This paper develops and validates a new cutting fluid application technique for creepfeed grinding with aluminium oxide grinding wheels. The new fluid delivery system incorporates several concepts found in the literature including high-speed fluid application, coherent jets, air scrapers and concentration effects associated with synthetic cutting fluids. Experiments were carried out on a Blohm Planomat 408 creepfeed grinding machine in Dalhousie University|s Grinding Laboratory. These experiments show that the new coolant delivery system can achieve an 83% increase in material removal rate over a state-of-the-art coherent jet and provide the capability of keeping the liquid cutting streams separate during creepfeed grinding. As a result, this new system has the potential to significantly increase production rates.

Keywords: creepfeed grinding; high-speed cutting; cutting fluid delivery; cutting fluid concentration; cubic boron nitride; grinding wheels; cutting fluids; aluminium oxide; material removal rate.
