研究了电火花加工和电解加工/电解研磨复合加工。首先，研究了电火花成形和电解加工技术。这些过程在同一机床上使用相同的电极（铜）和相同的加工液（水）依次进行。研究了电火花和电解复合加工的两种类型。一种是成形电极扫描，另一种是简单形状电极扫描。电极扫描复合加工适用于生产小型和各种形状的部件，而无需制作成型电极。通过电解加工，可将1μ mRa的电火花加工表面提高到0.2μ mRa。其次，为了获得更光滑的表面，开发了电火花-电解研磨复合加工新技术。电解研磨时间为2 min时，孔的表面粗糙度可达0.07μ mRa。阐述了孔形的复合加工技术的表面光整加工。
EDM (electrodischarge machining) and ECM (electrochemical machining)/ECM-lapping complex machining is investigated in this paper. First, EDM shaping and ECM finishing technology are investigated. These processes are carried out in sequence on the same machine tool with the same electrode (copper) and the same machining liquid (water). Two types of EDM and ECM complex machining are investigated. One is with a formed electrode, and the other is with simple-shape electrode scanning. The complex machining with electrode scanning is applied to produce small and various-shaped components without making a formed electrode. The EDM surface of 1μm Ra is improved to 0.2μm Ra by applying ECM. Second, in order to get a smoother surface, a new EDM and ECM-lapping complex machining technology is developed. The surface roughness of a machined hole is improved to 0.07μm Ra by applying 2min of ECM lapping. The surface finishing of a hole shape is demonstrated with the complex machining technology.
