Abstract

PURPOSE:To prevent the surface of an electrode from deformations caused by cracks or tears, etc. in the electric discharge machining process where a work is machined into the form of the electrode by the spark discharge by a method wherein the surface of an electroformed electrode is made from a nickel-tungstem alloy layer. CONSTITUTION:A tungsten-nickel alloy layer 4 is provided on the surface of a conductive coat 2 made on a matrix 1. A copper layer 3 having a desired thickness is provided on the upper surface (nonmachining surface side) of this tungsten-nickel alloy layer 4. This alloy layer 4 together with this copper layer 3 is stripped from the matrix 1 to obtain an electric discharge machining electrode which has the tungsten- nickel alloy layer 4 as an electrolytic surface (processing surface). Much time and cost are required for building the tungsten-nickel alloy layer but if an alloy layer of a desired thickness and then a copper layer are formed in this way, the mechanical strength of the electrode can be secured and the economy thereof can be insured.
