ABSTRACT:
An electrical-discharge machining apparatus for machining a workpiece using an aqueous machining fluid includes an insulator for electrically insulating a machine platen from the workpiece where the workpiece is placed. A machining-fluid-property measuring instrument measures the state of the machining fluid; and a machining-fluid-property controller maintains the pH of the machining fluid so as to be kept within 8.5 through 10.5.
