目前,用麻花钻钻削φ0.1～φ0.5mm的小孔仍是最主要的加工方法。可是用直径φ0.1～φ0.5mm的小麻花钻头钻削,有时钻削力只有几百克,用手动进给难以控制,往往造成钻头折断,导致工件报废。因此,微小孔的加工已成为钻削中的一大难题。本文叙述用微机控制普通台式钻床,实现微小孔加工进给过程自动化。 At present, the use of twist drill hole φ0.1 ~ φ0.5mm is still the most important method of processing. However, small diameter twist drill φ0.1 ~ φ0.5mm, sometimes only a few hundred grams of drilling force, with manual feeding difficult to control, often resulting in broken drill, leading to scrapped parts. As a result, the machining of tiny holes has become a major challenge in drilling. This article describes the use of computer-controlled ordinary desktop drilling machine, micro-hole machining feed process automation.
