ABSTRACT:
A machining center utilizing a traveling-electrode EDM machine in which a thin, continuous electrode element is supplied, transported, guided over a guide member and taken up to provide a continuously renewed span of electrode surface traveling over the guide member juxtaposed in electroerosive relationship with a workpiece. The guide member has a guide surface formed to impart a preselected geometry to the span of the electrode element and is detachably secured to a guide holder in the machine. The machining center includes a guide storage station for accepting a plurality of guide members the guide surfaces of which are different in geometry. A guide-member-changing device is operatively associated between the storage station and the machine to exchange guide member therebetween. The machine is also provided with an electrode handling unit for loading the electrode element onto the particular guide member transferred from the storage station and unloading the electrode element from that guide member to enable the latter to be removed by the changing device and transferred thereby back to the storage station. A numerical control unit is provided to furnish control commands to enable the system functions to be automatically performed.
