摘要 |
A molten residual layer formed on a surface 26 of an electric-discharge machined portion 12 of a metal molding member 1 is eliminated by using a tool 70 made by a wire discharge grinding method. According to the wire discharge grinding method, a minute tool which high in processing accuracy and high in hardness can be obtained. Since the molten residual layer formed on a surface 26 of the portion 12 due to the electric-discharge machining is eliminated by using the tool, the molten residual layer can be eliminated uniformly with high accuracy.
