近年来,随着切削加工技术的发展,各国对切削液的研究开发也极为重视。特别是对水溶性切削液的改进更为突出,最重要的发展方向就是合成型水溶性切削液的使用日益增多。目前,日本国内使用水溶性切削液的比率为33%,约占全部切削液的1/3左右;欧美各国水溶性切削液的使用比率更大,约50%以上。合成型水溶性切削液的优点如下: ①液体透明,可直接观察加工面的状况;
In recent years, with the development of cutting technology, various countries also attach great importance to the research and development of cutting fluid. In particular, the improvement of water-soluble cutting fluid is more prominent, the most important direction of development is the use of synthetic water-soluble cutting fluid is increasing. Currently, the proportion of water-soluble cutting fluid used in Japan is 33%, accounting for about 1/3 of the total cutting fluid; water-soluble cutting fluid in Europe and the United States a greater use rate, about 50%. The advantages of synthetic water-soluble cutting fluid are as follows: ① liquid transparent, can directly observe the status of the processing surface;
