Cleaning method of discharge machining fluid cleaning apparatus and the discharge machining fluid

摘要

Is used In the electro-discharge machining, duration of use and the environment, moisture mixed and oxidation is promoted by the situation, in order to obtain a clean method of discharge machining fluid cleaning apparatus and the discharge machining liquid to clean the degraded oil-based electric discharge machining fluid , in the present invention, electric discharge machining fluid of the oil system (23) is satisfied, the workpiece (24) by applying a pulse voltage between the electrodes for processing a workpiece (24) (12) a machining tank for performing processing (22), the machining liquid storage tank for storing electric discharge machining fluid used (23) at the processing tank (22) and (71), electrical discharge machining fluid discharge machining apparatus including a (23) in the discharge machining fluid cleaning apparatus for cleaning, in the flow path to flow discharge machining fluid (23) between the processing tank (22) and the processing liquid storage tank (71), specific gravity or more of the specific gravity of the discharge machining fluid (23) the a particle size has a structure comprising a cleaning material storage container cleaning member made of a porous material particulate is 0.01~10mm is stored.
