磨削效率和质量,除了砂轮材料与磨削参数、修整方式外,在很大程度上取决于磨削液的种类与供液方式。尤其是磨削难加工材料,因材料具有韧性大,塑性高,导热系数低,砂轮易粘附等特性,所产生的热量集中在磨削区不易散发,形成局部高温,易使工件表面烧伤。如不应用较好的磨削液和正确的供液方式,就会严重影响工件表面质量。数十年来,国内外许多研究者在这个领域曾做了大量研究工作,发明了多种高效优质的磨削液和各种供液方式。例如美国在一项专利(3,615,301)中介绍,磨削钛合金时最初的磨削比只有0.7左右,而使用该专利所发明的亚硝酸钠-甲酸钠磨削液时,磨削比可以提高到23.9。
Grinding efficiency and quality, in addition to grinding wheel material and grinding parameters, finishing methods, depends largely on the type of grinding fluid and the way for the liquid. In particular, grinding hard-to-process materials, due to the material with large toughness, high plasticity, low thermal conductivity, easy adhesion of the wheel and other characteristics of the heat generated in the grinding zone is not easy to emit, the formation of local high temperature, easy to burn the workpiece surface. If you do not use a good grinding fluid and the right way for the liquid, it will seriously affect the quality of the workpiece surface. For decades, many researchers at home and abroad have done a lot of research work in this area, invented a variety of efficient and high quality grinding fluid and a variety of liquid supply. For example, the United States describes in a patent (3,615,301) that the initial grinding ratio when grinding titanium alloy is only about 0.7. When the sodium nitrite-sodium formate grinding solution invented by this patent is used, the grinding ratio can be increased to 23.9 .
