一、前言在机械加工过程中,恰当地选用切削液能有效地降低加工成本,提高加工件表面质量。随着机加工工艺的发展,不仅要求切削液具有较好的润滑、冷却、清洗和防锈性能。而且还应满足节约能源和环保卫生等方面的要求。但是,目前国内广泛使用的乳化型切削液尚不能满足这些要求。国外从七十年代开始研制和发展了一种新型切削液——化学型无油水基透明切削液。国内于七十年代末期也开始了对 First, the preface In the machining process, the proper choice of cutting fluid can effectively reduce the processing costs and improve the surface quality of the workpiece. With the development of machining technology, not only requires cutting fluid has good lubrication, cooling, cleaning and anti-rust properties. But should also meet the requirements of saving energy, sanitation and other aspects. However, at present, emulsified cutting fluid widely used in China still can not meet these requirements. Abroad from the seventies began to develop and develop a new type of cutting fluid - chemical oil-free water-based transparent cutting fluid. The country also started right in the late seventies
