AI Technical Summary

Problems solved by technology

However, the main disadvantages and limitations of electrolytic machining are: (1) The complex end surface profile of the forming electrode varies with the workpiece to be processed. High requirements cause the electrode cost to account for about half of the entire processing cost; (2) It is difficult to achieve high processing accuracy and processing stability, which is caused by the instability of the electric field and flow field in the electrolytic processing gap, which is easy to cause processing Local expansion of the gap, especially difficult to process small holes or narrow seams

(3) When the area of ​​the formed electrode increases, the electrolyte in the machining gap is difficult to renew, and the heat and electrolytic products generated by electrolytic machining are difficult to discharge, resulting in low processing efficiency and poor processing quality
