微孔的加工方法

微孔的加工方法(中文4700字,英文2600字)
正如宏观加工一样，在微观加工中孔的加工也许也是最常用的加工之一。孔的加工方法有很多种，每一种都有其优点和缺陷，这主要取决于孔的直径、深度、工件材料和设备要求。这篇文章主要介绍了内冷却钻头钻孔、无冷却钻孔、插铣、电火花以及激光加工微孔的几种方法。

Options for micro-holemaking
As in the macroscale-machining world, holemaking is one of the most— if not the most—frequently performed operations for micromachining. Many options exist for how those holes are created. Each has its advantages and limitations, depending on the required hole diameter and depth, workpiece material and equipment requirements. This article covers holemaking with through-coolant drills and those without coolant holes, plunge milling, microdrilling using sinker EDMs and laser drilling.
