The potentialities concerning the combination of a cold-air minimum quantity lubrication technique (CAMQL) with a system for grinding-wheel cleaning by an air jet (WCJ) while grinding a heat-resistant nickel alloy are studied. The results of experimental studies show that, using the CAMQL + WCJ technique, the cutting force components are significantly reduced, the temperature of the contact interaction temperature exhibits a decrease, and the quality of the treated surface is improved owing to a decrease in the roughness and in the traces of adhesive interaction. The proposed technology, in the totality of functions, could represent a promising alternative for grinding with the use of traditional metal-working lubricoolants.
