ABSTRACT:
An EDM electrode wire changer has a plurality of conduits, one for each available electrode wire, all conduits converging towards the threading axis of a selected electrode wire through the workpiece or, alternatively, disposed substantially parallel on a slide that is indexable such as to dispose the outlet of a selected one of the conduits in alignment with the threading axis. A common motor-driven threading roller is disposed proximate the inlet of the conduits in a stationary position relative to the conduits, and a pinch roller for each wire co-operates with the threading roller for feeding the selected one of the wires through its corresponding conduit by forcing the selected wire against the peripheral surface of the common threading roller, while the other pinch rollers are remaining in a position away from the threading roller.
