    摘要: A layered anisotropically conductive element (11), a resistant element (12), and a feed element (13) constitute an electrode (14) for discharge machining. The layered anisotropically conductive element (11) includes conductive layers and low-conductive layers alternately laminated on each other, the conductive layers and the low-conductive layers being made of thin metallic plates coated with an insulative film. The layered anisotropically conductive element (11) has an anisotropic conductivity, in which the conductivity in a direction parallel to the low-conductive layers is much higher than that in a direction perpendicular to the low-conductive layers. The resistant element (12) is connected to one of layer-perpendicular end surfaces (11c) of the layered anisotropically conductive element (11). The feed element (13) is connected to the resistant element (12).

    摘要: An electrode for precision electric discharge machining having an improved machining rate and surface smoothness with respect to conventional graphite and copper electrodes. In accordance with the invention, the electrode (2) formed by silicon or other materials which have the same characteristics as silicon, a base of a low melting point metal or an alloy of such a low melting point metal covered with a layer composed of a mixture of the metal and a high resistivity inorganic compound. The outer layer may be formed by adhesion or by thermal spraying or by a powder metal sintering technique.
