The machining accuracy of electrochemical machining (ECM) is low since zones that far away from tool electrode are also machined. And the scattering of electrolyte solution during processing is also a severe environmental problem. To solve these problems, in this study, a novel method that not only limits the working area by sucking the electrolyte into the region between tool tip and the workpiece, but also prevents the electrolyte from scattering around was proposed. In this paper, the processing characteristics of some electrolyte solution with the proposed suction method, especially for the depth direction, were investigated. As a result, the machining accuracy by using a suction tool was greatly improved comparison with the dipping method.
