Study on Electrolyte Jet Turning

在电解液喷射加工(EJM)中，仅在被电解液喷射冲击的区域内通过通过喷射施加电流来加工工件。为了将这种方法应用到微棒的车削加工中，新研制了一种曲面平板射流。然后，在不含有害氢氧化钠的硝酸钠水溶液中，将EJM用于硬质合金的加工。与直流电流相比，交流电流加工可以在喷射下实现更多的局部加工。采用绝缘喷嘴可以有效地防止喷嘴磨损。

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.
