摘要： An electrolytic machining cathode electrode for producing a small diameter cavity in a metallic anode workpiece. The electrode has an elongated hollow metallic stem with a circular transverse cross section. The electrode is formed with an uninsulated working tip at one end and a hollow rear portion at the other end of larger outer diameter than the forward portion of the electrode for providing strength thereto. The outer surface of the electrode is coated with an electrical insulating material.

摘要： An electrochemical machining method and apparatus wherein electrolyte is impinged against a workpiece from non-conductive inert nozzles which do not penetrate the workpiece. The electrolyte is cathodically charged from an electrode remote from the nozzles so that very fine jets of electrolyte may be discharged. The nozzles are preferably made of glass and extend in a group or bunch from a header containing the electrode. The current potential is controlled to effect localized accurate cutting of the anodically charged workpiece by the cathodically charged electrolyte jets from each nozzle preventing overlapping of the cuts as by splashing or random uncontrolled jet flow. The outside dimensions of the nozzles have no effect on the size of the cut. In hole drilling operations, any undesired taper of the hole is removed by increasing the current potential after a through hole is formed to flow the electrolyte in a straight path for removing any stock creating the taper. Since the nozzles need not penetrate the workpiece, they may be stationarily mounted and hole patterns and spacings not obtainable with movable tools are now easily provided.
摘要翻译：一种电化学加工方法和装置，其中电解质从不穿透工件的非导电惰性喷嘴撞击工件。电解质从远离喷嘴的电极进行阴极充电，从而可以排出非常细小的电解液。这些喷嘴优选地由玻璃制成并且从包含电极的集管或一束中延伸出来。控制当前电位以通过来自每个喷嘴的阴极电荷的电解质射流来实现对阳极充电工件的局部精确切割，从而防止切割的重叠，如通过飞溅或随机的不受控制的喷射流。喷嘴的外部尺寸对切割的尺寸没有影响。在钻孔操作中，通过在形成通孔之后增加电流电位来消除孔的任何不期望的锥形，以使电解液沿直线路径流动以除去产生锥度的任何坯料。由于喷嘴不需要穿透工件，所以它们可以被固定地安装，现在容易地提供用活动工具不能获得的孔图案和间距。
