Abstract
A wire electric discharge machine including a wire electrode collecting device for collecting a wire electrode previously used for electric discharge machining, and a guide for guiding the previously used wire electrode to the wire electrode collecting device. The guide and/or the collecting device is movable so that the guide is movable relative to the collecting device in at least two different directions. In one embodiment, the wire collecting device is vibrated.
