Stacking-type combined electrode for electrosparking of micro inner grooves of slow wave structure and manufacturing method of stacking-type combined electrode

Abstract

The invention provides a stacking-type combined electrode for electrosparking of micro inner grooves of a slow wave structure. The stacking-type combined electrode comprises a positioning mandrel, and electrode plates which are large in diameter and serve as electrodes and spacers small in diameter are alternately arranged on the positioning mandrel in a sleeving mode. An axial positioning structure is arranged on the positioning mandrel, and thus the electrode plates and the spacers are positioned on the positioning mandrel. The combined electrode has the advantages that manufacturing is easy, the processing precision can be easily ensured, and distances of various micro grooves and wide grooves can be easily adjusted and combined to form series standards. When the combined electrode is used for processing the slow wave structure, the processing precision of the slow wave structure can be guaranteed. In addition, compared with an integral electrode, the stacking-type combined electrode has the advantages that abraded electrode plates can be conveniently replaced to achieve repeated use, and thus the using cost is lowered. The invention further provides a manufacturing method of the stacking-type combined electrode.
