近年来,为了节约能源和保护环境,对金属切削液的研究越来越引起人们的重视,一些科学技术比较先进的国家已广泛的采用了水质切削液,我国也有一些单位采用了水质金属切削液。在水基金属切削液中,乳化型金属切削液正在逐步被润滑、 In recent years, in order to save energy and protect the environment, more and more attention has been paid to the research of metal cutting fluid. Some countries with advanced science and technology have adopted water cutting fluid extensively. Some units in our country also adopted water metal cutting fluid . In water-based metal cutting fluid, emulsion-type metal cutting fluid is gradually being lubricated,
