摘要： An electric discharge machining module for forming a hole in a workpiece with an electrode is provided, comprising a module body, a spindle assembly and a piston assembly. The module body defines a throughbore extending along an axis. The spindle assembly is at least partially positioned within the throughbore for rotation around the axis and includes a first electrode passageway which is coaxial with the axis for receiving the electrode therethrough. The piston assembly is positioned within the throughbore for movement along the axis between a released position and an engaged position. The piston assembly includes a second electrode passageway which is coaxial with the axis for receiving the electrode therethrough. A collet closer of the piston assembly engages a collet of the spindle assembly when the piston assembly is in the engaged position such that the collet grips the electrode for unitary rotational movement of the electrode and the spindle assembly. The electric discharge machining module of the present invention facilitates multiple-spindle or multiple-electrode methods and apparatuses for performing a plurality of EDM operations simultaneously and in close proximity to one another.
