Study on ECM Characteristics in Hole Machining with Electrolyte Suction Tool

The machining accuracy of electrochemical machining (ECM) is low since zones that are far away from the tool electrode are also machined. Furthermore, the scattering of electrolyte solution during processing constitutes a severe environmental problem. To overcome these problems, this study set out to develop a novel method that not only limits the working area by sucking the electrolyte into the region between the tool tip and the workpiece, but also prevents the electrolyte from being scattered. In this paper, the processing characteristics of an electrolyte solution combined with the proposed suction method, especially in the depth direction, were investigated.
