As reported before, WEDM products can be quickly finished until mirror-like by ECM using the remainder part of the products as the electrode. This report concerns with the extended application of that method to the products of EDM sinking. Since it is often difficult to realize a uniform flow of the electrolyte in this applications, the system was designed as; 1) The electrochemical process takes place in a still electrolyte. 2) The flushing is achieved by the periodical lift-up of the electrode and the synchronized spray of the electrolyte.
The experimental results show the effectiveness of this method in the production of cavities including forging dies, injection moulds etc.
