The Cooling Effects of Cryogenic Pneumatic Mist Jet Impinging in Grinding of Titanium Alloy

Article Preview

Grinding is inherently characterized by high specific energy requirements, a high grinding zone temperature. Many methods have been employed in grinding high grinding zone temperature. But all have their shortfalls, both in cooling environmental pollution. Here a new high efficiency cooling technology—cryogenic mist jet impinging (CPMJI) cooling technology is offered. In this technology, coolant is carried by high-pressure cryogenic air (–20°C) and reaches the machining form of mist jet to enhance heat transfer in machining zone. This paper mainly cooling effects of CPMJI in surface grinding, compared with grinding with compressed flood cooling. CPMJI seems to have better effects than other cooling methods.
