在众多的机械加工中,小孔加工是加工技术中最难的一个分枝。小孔加工多用于钟表零件、柴油机的喷油咀孔、电子零件、计算机印刷板路、医疗设备、宇航、航空工业等,用途广泛,并在不断扩大。钻头小直径,大直径的区别在术语上没有明确的定义,JIS 中规定有小直径的直柄钻头,这是指直径小于2毫米的钻头,一般称为小直径钻头。本文所述极小直径是指φ0.1～φ1毫米,这类钻头,切削刃损坏情况,切削刃精度的确定,必须用放大镜或显微镜,用肉眼观察是困难的。随着直径的变小,在制造和使用时困难程
In many machining, the hole machining is the most difficult branch of processing technology. Hole processing and more used for watch parts, diesel nozzle hole, electronic components, computer printed circuit board, medical equipment, aerospace, aviation industry, a wide range of uses, and is constantly expanding. The distinction between small diameter and large diameter of drill bits is not defined in the jargon. JIS defines small diameter straight shank drill bits. This refers to drill bits smaller than 2 mm in diameter, commonly referred to as small diameter drill bits. This article describes the minimum diameter φ0.1 ~ φ1 mm, such drill, cutting edge damage, the determination of cutting edge accuracy, you must use a magnifying glass or microscope, with the naked eye is difficult. As the diameter becomes smaller, it is difficult to manufacture and use
