Abstract
An apparatus for electrical discharge machining (EDM) is disclosed having a housing and a workpiece support assembly secured to the housing for holding a workpiece in a predetermined location. An EDM electrode is attached to the housing for performing the EDM machining. A tank assembly is also attached to the housing and movable between a machining position and a retracted position. In the machining position, the tank assembly encompasses a workpiece secured to the workpiece support area and filled with a dielectric fluid necessary for the EDM machining process. In its retracted position, the tank assembly is spaced away from the workpiece to facilitate access to the workpiece for removal of the finished workpiece and reattachment of a new workpiece in preparation for the next EDM machining operation.
