使用电子束进行加工,一般都是把电子束经过聚焦变成很细的高密度能束之后,用于精密切割和高功能精密焊接等方面的加工。与此相反,这里将要介绍的电子束照射装置是通过特殊的技窍能对大面积产生较均匀的高能量密度的电子束。该装置原本是为代替义齿、义床制作中的手工抛光作业而开发的。
The use of electron beam processing, the general is to focus the electron beam into a very fine high-density beam, for precision cutting and high-precision welding and other aspects of the processing. In contrast, the electron beam irradiation apparatus to be described here is a technique that produces a uniform high-energy electron beam over a large area by using a special technique. This device was originally developed as a manual polishing operation in place of denture and bed construction.
