摘要： A nozzle for processing machinery, wherein a hard ceramics coating is formed on the surface of the base metal of the nozzle for processing the machinery to prolong the service life thereof. Since the hard ceramics coating is formed on the surface of the base metal of the nozzle for the processing machinery, the nozzle for processing the machinery is hard to be scratched on the surface thereof and highly resistant to heat. Thus, service life can be prevented from being shortened due to the occurrence of scratch by the contact thereof with a warped work during processing and the deformation thereof by heat in the nozzle for processing the machinery to realize an increased service life.

摘要： A wire electric discharge machine which applies a high frequency voltage between poles, i.e., a wire electrode (401) and a work (405) as the other electrode disposed facing the wire electrode (401) at a predetermined distance therefrom so as to generate intermittent discharge and machine the work. The machine comprises a DC voltage application unit (407) for applying DC voltage between the poles and a low frequency component detection circuit (408) for detecting the low frequency component from the voltage between the poles. The state between the poles is monitored according to the output of the low frequency component detection circuit (408), and the axial feed speed is adjusted according to the state between the poles.
