机械钻短槽孔制作方法

Manufacturing method of super-short slot of mechanical drilling

短槽孔的加工是机械钻孔加工的一个难点。文章在不影响生产效率、对制作资料不做改变的情况,只增加铣刀做预钻而很好地解决了短槽孔的变形及槽长公差不稳定的问题。

Manufacture of Super-short slot is a key point for mechanical drilling. This paper is to provide a new manufacturing method which increase only pre-drill hole using routing bit, and doesn＇t lower the production effectiveness, the cost and tooling manufacturing change is only tiny.
