切削液的使用对切削加工起着重要的作用。一般来说,如能正确使用切削液,可使切削速度提高15～30％,切削温度降低100～150℃,刀具使用寿命延长4～5倍,产品光洁度提高1～2小级,切削力减少10～30％。随着生产的发展,对加工零件的质量要求越来越高,因而切削加工的技术也不断进步,再加上节约能源、减少公害等原因,切削液的品种和性能也就不断地发展和完善。一、切削液的种类和特性切削液分为油性切削液和水溶性切削液,水溶性切削液一般又分为乳化液、化学合成液 The use of cutting fluid plays an important role in cutting. In general, if the cutting fluid is used properly, the cutting speed can be increased by 15 to 30%, the cutting temperature can be reduced by 100 to 150 ° C, the service life of the tool can be extended by 4 to 5 times, the finish of the product can be increased by 1 to 2 steps, and the cutting force can be reduced 10 to 30%. With the development of production, the quality requirements of the processing of parts getting higher and higher, so cutting technology has also been improved, coupled with saving energy, reducing pollution and other reasons, cutting fluid varieties and performance will continue to develop and improve . First, the type and characteristics of cutting fluid Cutting fluid is divided into oily cutting fluid and water-soluble cutting fluid, water-soluble cutting fluid is generally divided into emulsion, chemical synthesis solution
