ABSTRACT:
An electric discharge machine allows machining of a stationary workpiece by a device for moving the machining head and therefore the electrode vertically along the Z axis, a first chariot sliding along one of the X and Y axes, mounted on a cross beam resting on two shoulders laid out on both sides of the work zone, and cut out at the center to allow a shaft fixed to the device for moving the machining head to pass through. A second chariot slides along the other of the X and Y axes. The workpiece is supported by a worktable is supported by a column that is movable by a pair of fluid actuators. The fluid actuators may be powered hydraulically or pneumatically.
