Research On Equipment And Law Of Vibration Feeding Electrochemical Machining Of Micro-scale Multi-grooves

With the miniaturization and preciseness of the industrial products, microstructure has beenwidely used in aerospace, precision instrument, bio-medical and other fields. Because electrochemicalmachining has high efficiency, no tool wear, and no cutting forces and it removes material in ion form,it has unique advantages in machining microstructure. But in micro-electrochemical machining, it ishard to remove products of electrolysis in the gap and it is hard to renew the electrolyte, which restrictthe improvement of the precision and stability and limit its application in industrial production.This article is focused on micro-scale multi-grooves electrochemical machining, developselectrochemical machining vibration feeding equipment and studies the multi-grooves electrochemicalmachining when vibration feeding.
