The figure is a schematic diagram showing the configuration of this device.As the machining fluid in the electrical discharge machining tank (1) becomes contaminated with machining debris from electrical discharge machining, its specific resistance gradually decreases. Once collected in the sewage tank (2), the sewage is sent to the filter (4) by the pump (8).
The liquid is filtered and collected in the clear liquid tank (5). The cleaning liquid collected in the cleaning liquid tank (5) is fed to the ion exchanger (γ) by the pump (6), where the specific resistance value is reduced to 1.
After being subjected to a regeneration action of 0,000 to 100,000 Ωm, it is returned to the cleaning liquid tank (5).

さｎたものである。The cleaning liquid thus regenerated is fed to the electrical discharge machining tank (1) by the pump (8) and is provided for electrical discharge machining. When rough machining is performed for a long time using an electric discharge machining device, the cleaning liquid tank (5) flows from the dirty liquid tank (2) to the clean liquid tank (5).
) When the filter (4) is being fed to the tank (4), the filtration is not sufficient and sludge accumulates in the clean liquid tank (5). The filter (8) inserted between the steps usually has a filtration accuracy of 5 to 101
I paper filter is used. However, if rough machining is carried out continuously, sufficient liquid will enter the cleaning liquid tank (5) and this cleaning liquid will be transferred to the ion exchanger (5).
If ion exchange is performed as it is due to γ), fine particles from sludge will adhere to the ion exchange resin, reducing its function, and the original regeneration effect will no longer work.As a result, the ion exchange resin will have to be replaced more frequently. The present invention has been made to solve the above-mentioned problems, and aims to extend the life of the ion exchange resin. It was done for a purpose.
本発明に係る再生装置は、イオン交換装置の前にフィル

ことがない。According to the present invention, since the cleaning liquid passes through the -H filter before flowing into the ion exchange device, fine particles of the cleaning liquid are removed here, so that fine particles do not adhere to the ion exchange resin. do not have.
