Belt Grinding of TC4 Based on the Technology of Cryogenic Mist Jet Combined MQL

Abstract

To solve the problems of the reduces in belt life、low in metal removal rate and environmental pollution by using conventional grinding fluid, a new high efficiency and green cooling technology—— The Technology Of Liquid Nitrogen Cryogenic Wind Jet Combined MQL(LNCWJCM), It was used in belt grinding of TC4. The effect of LNCWJCM on grinding performance of TC4 was analyzed to compare with cold air 、liquid nitrogen and conventional flood cooling method. The experimental results indicate that LNCWJCM can improve metal removal rate and the life of belt, in addition , impacting on abrasive belt grinding from which the flow of liquid nitrogen, grinding temperature, the flow of oil droplets and other key parameters is studied.
