前言 1Cr18Ni9Ti不锈钢的化铣在六十年代我部首先应用。化铣槽液的主要成份是硝酸、盐酸、氢氟酸。由这种三强酸混合的化铣槽液不仅可化铣1Cr18Ni9Ti,而且可化铣其它种类的耐热不锈钢。它的缺点是化铣零件的表面光洁度较低,一般只能达到▽3—▽5。槽液中含有4当量的氢氟酸,分析调整困难,废液也难处理。为了去掉氢氟酸我 Preface 1Cr18Ni9Ti stainless steel milling in the sixties my department first application. The main component of the milling fluid is nitric acid, hydrochloric acid, hydrofluoric acid. Milling milling fluid mixed by the three strong acids not only can be milling 1Cr18Ni9Ti, but also milling other types of heat-resistant stainless steel. Its disadvantage is the lower surface finish of the milled parts, generally only ▽ 3- ▽ 5. Bath containing 4 equivalents of hydrofluoric acid, analysis and adjustment difficult, waste is difficult to deal with. In order to remove hydrofluoric acid me
