  • Electrode for electrical discharge machining and process for manufacturing the same
    Patent number: 5108555
    Abstract: Disclosed is an electrode for electrical discharge used for diesinking, comprising an electrode member produced by subjecting a base and binder of gypsum hemihydrate powder and a filler of conductive metal powder to modeling and/or molding and setting into a desired form of electrode, and followed by plating the electrode member with a conductive metal; and a process for manufacturing the same, wherein a gypsum hemihydrate powder, a gypsum dihydrate powder in an amount of 1% by weight of the gypsum hemihydrate powder and a conductive metal powder are kneaded in vacuo, and water is added thereto to continue further kneading in vacuo, followed by casting into a mold having a predetermined shape transferred thereon to carry out hydration, molding and setting to provide an electrode member; after the electrode member is dried, it is plated with a conductive metal to enhance mutual continuity in the conductivity of the former conductive metal powder and also to form a thin metal layer on the surface of the electro
