ABSTRACT:
A wire cutting type electrical discharge machining system compactly assembled due to improved arrangement. It includes a frame, a vertical column with upper and lower arms, a bed for supporting a feed device for an electrically conductive workpiece, and a vertically elongate mounting plate. The mounting plate secured, at a lateral part thereof on one of opposite surfaces thereof, to the rear side of the column is provided with a wire supply/take-up assembly mounted on the same surface where it is fixed to the column. On the other surface of the mounting plate a box accommodating an electrical discharge controller is fixed. This arrangement is helpful in facilitating the assemblying operation of the system, in good use of a possibly formed dead space above the bed, and further in simplifying the wire path by arranging the wire supply unit in alignment with the upper arm, and the wire tape-up unit in alignment with the lower arm.
