Abstract: In order to improve the machining efficiency and quality of small holes, and make up some defects
of the electrochemical jet machining, an ultrasonic assisted electrochemical jet machining device including the
piezoelectric transducer and the conical cavit is proposed. The ultrasonic-assisted electrochemical jet machining
device is built, and its machining principle is analyzed. The sound field simulation and electrochemical jet
machining simulation are carried out, and the ultrasonic assisted effect is preliminarily verified. The experiment
results verify the assisted effect of ultrasonic wave on the machining rate and shape of small hole of the
electrochemical jet machining. The results show that under the conditions of multiple groups of NaNO 3
electrolyte concentration and hydraulic pump speed, the machining rate of ultrasonic assisted electrochemical
jet machining can be increased by 9%–15% within 1.5 min. At the same time, ultrasonic wave improves the
overcutting phenomenon of electrochemical jet machining.
