Wire-electrochemical cutting with a NaNO3 electrolyte

Enhancement of performance of wire electrochemical micromachining using a rotary helical electrode

“…Maeda et al (1984) found that the maximum feedrate of the wire electrode was obtained at a critical pressure, which was related to the nozzle diameter and the length of the wire span. Béjar et al (1995) experimentally verified that a passivating electrolyte of NaNO 3 was beneficial for improving the feedrate and the accuracy of an NaCl electrolyte. However, electrolyte refreshment in the above-mentioned methods was still slow and limited the machining efficiency.…”

“…According to equation(1), derived from Faraday's law and electrochemical machining theory (McGeough, J.A., 1974), the machining gap, Δ, is nonlinearly inversely proportional to the electrode federate, υ.…”

Advancement in electrochemical micro-machining

“…Maximum feed rate can be achieved with sodium nitrate electrolyte. Sodium nitrate is more advantageous than the other electrolytes due to its lower throwing power, and high and controlled metal removal, which leads to high-speed and accuracy in machining [54]. Jet EMM, where an electrolyte jet plays a vital role during machining, as shown in Fig.…”

Study on the wire electrochemical groove turning process

“…When the rotational speed is high, smaller thickness is removed per revolution. When the process stops, a step height will remain in the place where the electrode happens to be at the moment [21,22]. However, this step is spread over the width of the wire which is exposed to the machining.…”
