以前我们加工一种管道内孔为φ80 × 600的零件时,由于工件内孔表面光洁度要求在▽▽▽▽10以上,所以,都是靠粗车、精车、珩磨及抛光等加工完成的。这样,不仅生产效率很低,而且也比较麻烦。后来通过试验,我们采用了浮动滚压代替珩磨和抛光的方法,既简化了操作也提高了效率。一、结构:在大批生产时,浮动滚压工具的结构如附图所示。它是由8个零件组成 In the past, when we machined a part with a pipe inner diameter of φ80 × 600, the surface finish of the inner hole of the workpiece was required to be ▽ ▽ ▽ ▽ 10 or above. Therefore, it was completed by roughing, finishing, honing and polishing. In this way, not only the production efficiency is very low, but also troublesome. Later, through the experiment, we adopted the method of floating roller instead of honing and polishing, which not only simplified the operation but also improved the efficiency. First, the structure: In a large number of production, the structure of floating rolling tool as shown in the figure. It is composed of 8 parts
