摘要： An electrochemical machining apparatus is disclosed for removing material from a workpiece. The electrode has a conical tip and an electrolyte is supplied around the outer periphery of the electrode to a gap between the electrode and the workpiece. The combination of the conical tip and the electrolyte being supplied around the outer periphery of the electrode ensures that the gap between the electrode and the workpiece will be maintained at a predetermined distance preventing short-circuiting or uneven drilling of the workpiece.

摘要： A source of intermittent unipolar voltage pulses is connected across an electrode and a workpiece to be machined, defining between them an erosion gap which is swept by a continuously moving, slightly electrolytic liquid. With suitable spacing of the pulses, the flow of the liquid removes excess ions and detritus from the erosion gap while its conductivity limits the voltage peak at the beginning of each discharge. To insure an even distribution of the flow, the liquid is admitted to the gap from above through one or more passages formed in the electrode, spreading symmetrically in opposite directions.
摘要翻译：间断单极电压脉冲的源极连接在电极和待加工的工件之间，在它们之间形成一个被连续运动的轻微电解液体扫过的腐蚀间隙。通过脉冲的适当间隔，液体的流动将过多的离子和碎屑从侵蚀间隙中除去，同时其电导率限制了每次放电开始时的电压峰值。为了确保流动的均匀分布，液体通过形成在电极中的一个或多个通道从上方进入间隙，在相反方向对称地扩展。
