Abstract

The paper introduces a method for drilling into hard non-conductive materials by localized microwave radiation (US patent 6,114,676). The microwave drill utilizes a conventional microwave source (2.45-GHz magnetron) to form a portable and relatively simple drilling tool. The drilling head consists of a coaxial feed with a near-field concentrator. The latter focuses the microwave radiation into a small volume under the drilled-material surface. The concentrator itself penetrates into the hot spot created in a fast thermal runaway process. The drilling debris is removed mechanically. This microwave device can be used to drill into concrete, silicon, ceramic, rocks, glass, plastic, and even wood. Hole diameters obtained so far range from 0.5 mm to 13 mm. The larger holes are produced with a slight mechanical assistance. The paper presents recent experimental results of the microwave-drill in various ceramics.

微波陶瓷钻
本文介绍了一种利用局部微波辐射在硬质非导电材料上钻孔的方法(美国专利号:6,114,676)。微波钻利用传统的微波源(2.45 ghz磁控管)形成一种便携且相对简单的钻孔工具。钻孔头由同轴进给器和近场集中器组成。后者将微波辐射集中在钻孔材料表面下的一个小体积内。浓缩器本身穿透到在快速热失控过程中产生的热点中。钻屑用机械清除。这种微波设备可以用来钻入混凝土、硅、陶瓷、岩石、玻璃、塑料甚至木材。目前获得的孔径范围为0.5 mm至13 mm。较大的孔是在轻微的机械辅助下产生的。本文介绍了微波钻在各种陶瓷中的最新实验结果。
