Problems solved by technology

However, the patent is said to have several drawbacks

First of all, this kind of device uses a vibration drive unit and a proportional mechanism to drive the processing electrode or workpiece to vibrate. Since the vibration device and the electrochemical processing device are not independent, this mechanical structure will not work for a long time. There is wear and is not stable enough, which affects the machining accuracy of electrochemical machining

Secondly, the vibration frequency of the vibration drive unit of this structure is not high enough to produce the cavitation effect of ultrasonic waves, and cannot fully improve the fluidity of the electrolyte and the discharge of electrolytic products.
