摘要
A Tandem-type micro electro-discharge machining (EDM) apparatus comprises a EDM machining stage, a gradation twin-wire EDM device, an electrode tool, a workpiece, and a resistor-capacitor (RC) EDM circuit. The gradation twin-wire EDM device further comprises a wire supply reel unit, a wire take-up reel unit, a stepped insulating roller, a twin-wire conductor unit, and a discharge circuit unit. With the design of the gradation twin-wire EDM device, only one single EDM procedure is needed to simultaneously perform rough EDM and finish EDM processes together on the electrode tool to form a required micro electrode tool, which can be immediately used to perform micro-hole EDM or scanning EDM on the workpiece. Therefore, the Tandem-micro EDM apparatus of the present invention can be functioned automatically to achieve mass production of micro holes EDM and reduce machining time and improve machining efficiency and product's quality.
