一、概况化学铣切是无切削加工工艺方法之一。我国七十年代开始应用。它的原理是:金属在酸碱溶液中产生金属溶解(腐蚀),对金属进行外形加工。随着我国宇航工业的不断发展,化铣工艺的应用也日益广泛。用化学法溶解金属,早在几十年前已用于装饰品加工,如铭牌、雕刻、印刷制版等,但作为一种专门金属外形加工工艺还只有近廿年的历史。它适合加工大型薄壁、刚 First, the overview Chemical milling is cutting-free processing technology. China’s seventies began to apply. Its principle is: Metal in the acid solution generated metal dissolution (corrosion), the shape of the metal processing. As China’s aerospace industry continues to develop, the application of milling technology is also increasingly widespread. The use of chemical methods to dissolve metals has been used for ornament processing decades ago, such as nameplates, engravings, plate-making, etc. However, it has only a history of nearly 20 years as a specialized metal contouring process. It is suitable for processing large thin-walled, just
