(一)问题的提出 微波中继通讯是目前通讯中最先进的技术。其中主要的微波波导元件,要求机械加工精度高,电性能要求也严格。我们在近几年微波波导元件的制造过程中摸索出一种新的工艺方法,称为镀层缠绕新工艺。 过去制造微波元件是采用电铸的方法。其缺点之一是耗电量大、工期长,制造一个元件就要腐蚀掉一个模具;二是在电铸后安装法兰盘的过程中,放在夹具上的元件一不小 (A) the issue of microwave relay communications is the most advanced communication technology. One of the main microwave waveguide components, requiring high machining accuracy, electrical performance requirements are also strict. In recent years, we have found a new process method in the manufacture of microwave waveguide components, called the new coating winding process. In the past, microwave components were fabricated by electroforming. One of its shortcomings is the large power consumption, long construction period, the manufacture of a corrosion of a component will have a mold; the second is the process of installing the flange after electroforming, on the fixture on a not small
