在过去十年中,机床性能有了大幅度的提高。在这期间为了与金属切削的精度相适应,切削液同样有不少明显的发展。主要有:从纯矿物油转为溶性油质;从有酚转为无酚、摆脱了亚硝酸盐;添加剂与抗微生物剂的应用增加了。近来发展方向集中在半合成与合成切削液上。由于技术的进步使溶性油质切削液应用日趋广泛而且性能好,使用周期长。切削液可以分成二个基本类型:即纯矿物 In the past ten years, machine tool performance has been greatly improved. During this period in order to adapt to the accuracy of metal cutting, cutting fluid also has a lot of obvious development. Mainly from: pure mineral oil to soluble oleaginous; from phenol to no phenol, get rid of nitrite; additives and the application of antimicrobial agents increased. Recent development focuses on semi-synthetic and synthetic cutting fluids. As the technology advances so that soluble oil cutting fluid is widely used and good performance, long life cycle. Cutting fluid can be divided into two basic types: pure minerals
