It is a perspective view of the main parts, (1) is an electrolytic solution tank (2) filled with an electrolytic solution (2) such as sodium oxalate, sodium chloride, etc., and (3) is a cover such as an iron mold. The conductor layer (4) on which the workpiece (7) is placed is the pole of the machining 1 moving in close proximity to this workpiece (7) and is made of copper or graphite. (5) This processing electrode (
4) and a processing power supply (6) for applying a voltage between the conductor layer (7), this processing electrode (4) is attached in an insulated state, and this addition'@pole (4) is connected horizontally and vertically. It is a moving mechanism for moving. (8) is a data holding means for holding C data for movement in this moving mechanism, and data corresponding to the shape of the workpiece (7) to be finished is used as this NC data. . Further, as this data, the data obtained when cutting the workpiece (7) may be used. On the other hand, (9) is a hole for circulating the electrolyte (2) provided in the machining electrode (4), and the electrolyte is discharged from the machining electrode (4) by the pump (10). It circulates like this.
