减轻某产品细长管内膛阴阳线腐蚀技术研究

Technological Research on Reducing Corrosion on Groove and Land in Bore for Elongated Tubing Parts

某细长管为该产品中的重要零件,其内孔槽线要求进行电解加工成型。通过对电解加工特点的合理利用、制作专用工装以及制定专用工艺等方法,探讨了减轻电解加工后内膛膛线腐蚀的最佳办法,解决了某产品内膛出现“不均匀腐蚀斑”的问题,在成品满足生产需要后,可指导细长管的生产实践。

A elongated tubing was one of the important parts for certain products,which was specified that the bore rifling was done by electrolyzing.By using the features during electrolyzing,it was concerned on how to fabricate the special toolings and to establish the process,so as to find out the optimum method reducing the corrosion on groove and land in bore.After meeting finished products demand,it can be applied to the production of the long tube parts.
