Abstract
A sintered electrode for electric discharge machining comprises a continuous phase consisting of a conductive region (3), and a dispersed phase consisting of microscopic polycrystalline diamond (2) dispersed in the continuous phase. The conductive region (3) is cobalt, nickel, cobalt nickel alloy or cemented carbide and imparts conductivity to the electrode (1). The microscopic polycrystalline diamond (2) imparts excellent mechanical strength and thermal diffusion to the electrode (1). The electrode (1) and the workpiece (5) are connected to a power supply (V1) in reverse polarity and a current pulse having ON-time of 60 .mu. seconds or less and 1 .mu. second or more and peak of 15 A or less and 1 A or more is supplied to the electrode (1) from the power supply (V1).
