摘要： PROBLEM TO BE SOLVED: To form a surface treated layer to satisfy the specification requested to a work to be treated by providing an electric discharge treatment condition control part to control the discharge treatment condition of an electric discharge treating means by the output result from an electrode characteristic storage part and the requested specification of a requested specification storage part. SOLUTION: The requested specifications such as the hardness, the wear resistance, the film thickness and the surface roughness of a surface treated layer to be formed on a work are stored in a requested specification storage part 3, and the characteristics on the discharge of a dust electrode, for example, the composition of the electrode material, the electrode length and the electrode area are stored in an electrode characteristic storage part 2. The discharge treatment condition such as the polarity of the discharge pulse, the peak current, the open voltage, the pulse-ON time, the pulse-OFF time or the servo voltage suitable for the discharge treatment are set by a discharge treatment condition control part 4 by the storage parts 2, 3. The discharge treatment is achieved by a discharge treating means 1 based thereon, and the discharge treatment is completed when the surface treated layer meets the requested specifications.
