I do not have photographs but will try to get some.

The Fanuc wire cut machines have a optional re-threading attachment. The
wire is chopped clean as it
could be bent by a previous operation where the wire might have
bent,stretched etc.,

A water jet is then introduced through the wire guide. The wire stands erect
and is then fed straight through
the second wire guide. The machine can retry several times till successful.
