Abstract
Provided are an eccentric electrode for an electric discharge machining apparatus, a method of manufacturing the same, and a micro electric discharge machining apparatus including the same that are capable of generating a micro cylindrical shape on a workpiece with simple operations. The electrode for an electric discharge machining apparatus having a machining head is provided. The electrode includes a first member rotatably attached to the machining head and having a rotation axis, and a second member mounted on the first member, eccentrically disposed with respect to the rotation axis of the first member, and having an inverse tapered shape facing away from the machining head. Accordingly, a conveyance path for machining the object being processed can be simplified to increase its efficiency.
