摘　　要：高频窄脉冲电解加工(HSPECM)电源工作波形能否满足电解加工工艺的特殊性要求,波形是否稳定,直接决定了产品的质量。精密400A电源样机已长期成功应用于剃须刀丝网刀片微细小孔(0.20mm)和弧形窄槽的试生产。在此基础上500A、25kHz工程化样机亦开始批生产。在电源研制及试生产的过程中,进行了一系列关于电源工作波形稳定性的试验,归纳出常见的波形畸变现象,进而提出并实现了改善波形畸变的技术措施。Whether waveform of HSPECM （High Frequency Short Pulse Electro Chemical Machining） power supply meets the particular demand of ECM process and has good stability will directly affect product quality. The precision 400A model of HSPECM power supply has been applied to trial production of micro pore （0.20mm） and arc-shaped narrow groove in shaver. Based on this, the 500A, 25kHz industrialization model of precision HSPECM power supply is being applied to batch production. In process of development of HSPECM power supply, we have carried out a series of characteristic experiments about operating waveform distortion, and have summarized several common types of it and corresponding technical approaches to improve it.
