The Law Technology Study and the Mechanism Analysis of Small-Size Machined by Electro Jet Machining

Abstract

In order to research the Law technology and the equipment performance of Electro Jet, The institute developed an electro jet machine. Through a large number of experiments on this machine, the author concluded its process law and analysis the corrosion mechanism to the removed process. The results show that, duty cycle and frequency have a certain effect on the machine accuracy, and duty cycle is the main factor of aperture morphology. When duty cycle varies from 30%~40%, the stray corrosion is less. Frequency affects the depth seriously, based on the original experiment, voltage, duty cycle. Frequencies were not interactive within the scope of the study. The corrosion of anodic workpiece satisfies Faraday law by the study of material removal mechanism. Current efficiency is less than 1, and it’s 40%~60%.current density is 2~4.5A/mm2, that is larger than ordinary electrochemical machining.
