Electric discharge machine with working fluid processing device.

摘要

The present invention relates to the maintenance and management of filters in a wire electric discharge machine. A sensor for detecting the filtration pressure is disposed between the filter and pump in the working fluid circulation channel. The sensor output is sequentially displayed as a graph on a display device. The operator is thereby able to comprehend the progress status of filter clogging by checking such sensor output (transition of water pressure) at the time of commencing the processing. <IMAGE>
