A chip removing device used in an electro-discharge machining using a discharge electrode. The device comprising a lower plate adapted to be disposed to the surface of the workpiece to be machined, an upper plate having an inner surface defining a cavity, and a machining oil chamber adapted to communicate with a gap defined between a discharge electrode and the portion of workpiece machined by the discharge electrode and supply machining oil under pressure thereto. The machining oil chamber is defined by the cavity and the outer surface portion of the discharge electrode exposed to the cavity as the discharge electrode penetrates the upper plate and the lower plate during the electro-discharge machining. A nipple is also provide for communicating with the machining oil chamber and supplying machining oil under pressure from a machining oil supply thereto. As machining oil under pressure is supplied to the gap, the removal of chip is effectively achieved.
