With more attention paying to the environment, green manufacturing (GM) has become inevitable trends in 21st century. Green cooling technology as one branch of GM always was one research hotspot in manufacturing. In this paper, a new high efficiency cooling technology based on GM is proposed, called as CPMJ. In this technology, a little quantity of 0 °C water is carried by high pressure cryogenic air (–20 °C) and reaches the grinding zone in the form of high speed mist jet to enhance heat transfer and gain the best cooling effect. Heat transfer experiments and grinding experiments were carried out to evaluate the cooling effects of CPMJ. Experimental results indicated that CPMJ can offer better cooling effects compared with cold air jet and flood cooling method. Grinding temperature was effectively reduced during grinding of titanium alloys with CPMJ.
