Abstract:
To provide a wire electrode removal device of a wire electric discharge machine, the wire electrode removal device including a wire-electrode guide unit that guides an end on a cut point side of a wire electrode cut by wire-electrode cut devices to outside of a running path, a rewind shaft that pressure-fixes the wire electrode on the cut point side guided by the wire-electrode guide unit with an end face thereof and rewinds the wire electrode on a columnar member having angular portions with subsequent rotational driving thereof, a rewind-shaft drive unit that drives the rewind shaft to perform pressure fixing or pressure releasing of the wire electrode with the rewind shaft, a scraper member that removes a wound wire electrode from the columnar member at a time of pressure releasing of the rewind shaft by the rewind-shaft drive unit, and a collection member that collects the removed wire electrode.
