Abstract

PURPOSE:To prevent a deformation of a table resulting from a temperature difference between a processing liquid and the table by circulating the processing liquid within the table of an electric discharge machining device, which fixes a work. CONSTITUTION:A machining tank 24 is provided on a table 20 whose horizontal location is controlled to a base 10. A work 28 is fixed on the table 20, and electrical discharge machining is carried out with an electrode 14 under a condition of the machining tank filled with a processing liquid. During a process the processing liquid is supplied to the machining tank 24 through a pump 44 and a valve 50 from a processing liquid tank 32 and the processing liquid including processed dust and carbon dust is sent to a contaminated liquid tank 32a. At the same time the processing liquid is supplied to a sealed container 54 formed at the center of the table 20 through a valve 56, which is made to circulate to the contaminated liquid tank 32a and a temperature of the table 20 is kept equal with that of the processing liquid.
