Problems solved by technology

[0005] The vibration electrolytic machining mechanism is mostly used in the crank slider mechanism and electromagnetic drive mode. The crank slider mechanism is difficult to achieve high-frequency machining, and the amplitude adjustment is difficult, and there is impact force in the process; electromagnetic drive can achieve high frequency, but the structure is complicated. , the driving force is small, and the load cannot be too large, so the application fields of these two mechanisms are limited
