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.
In this paper, performing experiment on abrasive belt grinding of glass reinforced plastic, the reasons why belt is slipping is analyzed under such circumstances when glass reinforced plastic is grinded by wet abrasive belt, a basis for the fiber reinforced plastic properties of an effective method of grinding is proposed, a solution that belt is slipping in the process is proposed too. At last, a basis is given to choose the correct hardness which on depend different parts of the hardness of the round of contacts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
