Edm oils are used as the working fluid in electrical discharge machining(edm), alsocalledas spark erosion machining. These oils have The ability to provide uniform insulation and then to permit controlled electrical discharge at the breakdown voltage. EDM oils function as an Insulator between tool & work-piece, a spark conductor, a coolant and a flushing medium for chip removal.
