Study on Electrolyte Jet Turning

在电解液射流加工（EJM）中，通过射流施加电流，工件仅在被电解液射流击中的区域进行加工。为了将该方法应用于微棒的车削加工，研制了一种弯曲平面射流。然后，将EJM应用于不含有害氢氧化钠的硝酸钠水溶液中加工硬质合金。与直流电流相比，用交流电流加工可以在射流下进行更局部的加工。采用绝缘喷嘴可有效防止喷嘴磨损。

In electrolyte jet machining (EJM), the workpiece is machined only in the area which is hit by the electrolyte jet by applying an electrical current through the jet. To apply this method to the turning process of micro rods, a curved flat jet was newly developed. Then, EJM was applied to machining of cemented carbide using a sodium nitrate aqueous solution without including hazardous sodium hydroxide. Machining with AC current enables more localized machining under the jet than DC current. Use of an insulated nozzle was effective to prevent the nozzle wear.
