This study will attempt to combine micro-EDM with electrophoretic deposition polishing to fabricate a mirror-like surface of metal glass. First, a tungsten carbide rod is machined to the required 200 μm diameter using WEDG and micro-EDM at different conditions is used for producing a micro- tool due to melt at high temperature. A micro- tool is coated at various parameters by electrophoretic deposition. Furthermore, it is tested to finish the EDMed micro-mold surface by electrophoretic beposition polishing , instead of the method using conventional ionizing particles and punching machining. The processing parameters, such as various particle concentrations, sizes, surfactants, current density, shape effect and tool life, will be discussed to find steady quality of micro tool and the effect of surface roughness. It expects to develop a novel process of precision micro-concave mold to conform to demand of precision engineering.
