Electrode with outside flow of electrolyte for electrochemical machining and method

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.
