小直径深孔成形及其位置度保证方法解析

Analysis of Small Diameter Deep Hole Forming and Its Position Guarantee Method

小直径深孔的成形在机加工领域一直面临着诸多难题,如钻削时采用不恰当的参数导致钻头的折断;钻削后小孔出口处位置度不佳;加工时钻头的长径比过大导致钻头全跳动差等。文章介绍了一种采用通用设备加工小直径深孔的方法,在有效地提高其粗糙度的同时,也可保证其位置度。

The processing of small diameter deep holes has been faced with many problems in the field of machining, such as the fracture of abit is caused by improper parameters in drilling, the small hole outlet position is poor after drilling, the ratio of the length to diameter of the drill is large to cause drift full difference. This paper introduces a method of machining small diameter deep hole by general equipments. It can effectively improve its roughness and ensure its position.
