摘要：A flushing device having therein a chamber into which dielectric fluid is suppliedfor injecting dielectric fluid into a machining gap formed between a workpiece beingmachined and a wire electrode in a wire-cut electric discharge machine, a nozzle movable

between a first position and a second position that is nearer the workpiece than the firstposition, for directing the dielectric fluid in the chamber toward the machining gap; and aspring or other bias apparatus for holding the nozzle in the first position. The springconstant of the spring or bias apparatus being such that during a first cut, when dielectricfluid is supplied to the chamber at a higher pressure, the force from the fluid pressure issufficient to overcome the force of the spring or other bias apparatus, and the nozzle iscaused to move to the second position; and during a skim cut, when the dielectric fluid issupplied to the chamber at a lower pressure, the force from the fluid pressure isinsufficient to overcome the force of the spring or other bias apparatus, and the nozzleremains at the first position.
