    Patent number: 6486429
    Abstract: An EDM machine for machining a workpiece is disclosed. The EDM machine includes a machine frame having a central stationary machine body and a machining electrode to machine the workpiece. Machining occurs by producing a relative movement in at least one of an X axial direction and a Y axial direction between the machining electrode and the workpiece. The machine also includes a first axial slide for moving at least one of the workpiece and the machining electrode in the X axial direction, and a second axial slide for moving at least one of the machining electrode and the workpiece in the Y axial direction. The first axial slide is mounted in a substantially vertical plane on the machine body for lateral movement in a substantially horizontal direction.
