电抛光工艺在国内外生产上应用已久,尤其在产品另件、医疗器械及计测工具表面精加工等方南应用较为广泛,但在型腔模具制造工艺中,就目前所知是比较少见的。近年来,虽然国内有许多兄弟单位在这方面曾经做过很我工作,也积累了许多宝贵经验验,但是至今尚未成功的用于生产。为了减轻繁重的体力劳动,实现型腔模具制造电加工化,在模具电蚀加工后采用电解抛光进行精加工。就是说,电解抛光前的模具,经过电蚀加工的型腔尺寸必须留有必要的抛光余量(四周侧面约0.20～0.30毫米,深度为侧面的70%),表面光洁度达到(?)_6～
Electropolishing process has been applied in domestic and foreign production for a long time, especially in parts such as product, surface treatment of medical instruments and measurement tools, etc. It is widely used in the South, but in the process of cavity mold manufacturing, of. In recent years, although many fraternal units in China have done a great job in this field and have accumulated many valuable experience, they have not yet been successfully used for production so far. In order to reduce the heavy manual labor, to achieve the cavity mold manufacturing electroforming, electroforming in the mold after the electrolytic machining for finishing. That is to say, the mold before electropolishing must have the necessary polishing margin (about 0.20-0.30 mm on the side and 70% on the side) after electro-etching the cavity size, the surface finish reaches (?) _6 ~
