Abstract
Micro machining of tungsten carbide by electrochemical machining was studied. In ECM, machining conditions and electrolyte should be chosen carefully according to the property of workpiece materials. In this paper, sulfuric acid and nitric acid were used for tungsten carbide machining and machining characteristics were investigated according to machining conditions such as electrolyte, workpiece potential and applied pulse voltage. By using mixture of sulfuric acid and nitric acid, micro structures with sharp edge and good surface quality were obtained. Micro electrochemical turning was also introduced to fabricate micro shafts.
