Research on a high frequency short pulse power supply for electrolytic micromachining

Electrolytic micromachining possesses many special advantages and materials are removed through ions transferring based on the anodic dissolution mechanism during electrolytic machining. Consequently it should be a promising micromachining technique in the future. By application of pulse power supply, the machining gap can be decreased greatly, and thus the high shape accuracy and dimensional accuracy can be achieved. The high frequency short pulse power supply is a key technology for electrolytic micromachining. In this paper, based on the characteristics of electrolytic micromachining, a high frequency short pulse power supply for electrolytic micromachining has been developed successfully. The hardness makeup and the principle of work of pulse power supply are introduced in detail. At last, through machining experiments, the satisfactory process results are obtained.
