金属加工液是机械加工工业重要的配套材料,它的质量、水平、品种直接影响机械零部件的加工质量、生产效率、能耗与材耗,以及改善环境等。金属加工液使用量约占整个润滑油品总量的20%左右,所以国内外都很重视研究开发与推广应用金属加工液。我国在“六五”、“七五”,乃至“八五”都安排了金属加工液的攻关任务。 Metalworking fluid is an important supporting material for the machining industry. Its quality, level and variety directly affect the processing quality, production efficiency, energy consumption and material consumption of machinery parts, as well as improving the environment. Metalworking fluid usage accounts for about 20% of the total amount of lubricating oil products, so both at home and abroad attach great importance to research and development and promotion of the use of metalworking fluids. In the “Sixth Five-Year Plan”, “Seventh Five-Year Plan” and even the “Eighth Five-Year Plan”, our country has arranged the tackling tasks of metalworking fluids.
