Abstract
Provided is an automatic wire threader for a wire electric discharge machining apparatus including a jet nozzle (). The jet nozzle includes a first finger and a second finger () that are movable between their open positions where a jet nozzle hole () is undefined and their closed positions where the jet nozzle hole is defined. The jet nozzle further includes a compression coil spring () for urging the first finger and the second finger to their open positions. A moving device moves the jet nozzle from the retracted position to the operational position, so as to bring the first finger and the second finger in contact with a flush nozzle, thereby moving the first finger and the second finger against the a compression coil spring toward their closed positions.
