目前,微孔加工技术现已广泛应用于手表夹板、化纤喷丝板、喷气发动机喷嘴、电子计算机打印头、印刷电路板、电视机障板、天象仪星孔板、航空陀螺仪表元件、飞机透平叶片以及医疗器械中的红血球细胞过滤器等零件的加工领城。根据小孔的尺寸范围划分为六档。小孔:1.00～3.00(mm);次小孔:0.40～1.00;超小孔:0.1～0.40;微孔:0.01～0.10;次微孔:0.001～0.01;超微孔:<0.001。到目前为止,微孔加工的方法约有50种之多,有代表性的共有26种(见表1),按加工原理可分为机械加工和特种加工两大类。本文介绍机械式微孔加工的现状及其发展。
At present, the micro-hole processing technology is now widely used in watch splint, chemical fiber spinneret, jet engine nozzle, computer print head, printed circuit board, TV baffle, planetarium star plate, aeronautical gyro meter components, Flat blade and medical equipment in the red blood cell filter and other parts of the processing of the city. According to the size of the hole size is divided into six files. Holes: 1.00 to 3.00 (mm); Holes: 0.40 to 1.00; Holes: 0.1 to 0.40; Holes: 0.01 to 0.10; Holes: 0.001 to 0.01; Holes: <0.001. So far, about 50 kinds of microporous processing methods, a total of 26 kinds of representative (see Table 1), according to the processing principle can be divided into two major categories of machining and special processing. This article describes the status and development of mechanical micro-machining.
