    Abstract: An impulse generator for the spark erosive cutting of workpieces by electrodes of a liquid or solid medium, consists of a control circuit and a principal circuit. The control circuit contains: the control circuit contains an oscillator, reduction stages for the generation of elements which belong to the impulse signal, a counter for the addressing of impulse signal, a memory of a feedback circuit which detects the electrical conditions in the working gap, and a ROM with programmed memory locations, which are addressed by the counter according to the addresses of the impulse elements and by memory according to the addresses of the electrical conditions in the working gap, whereby the contents of the memory locations generate an output signal or no output signal. The principal circuit contains two electronic switches for the generation of a working impulse in the working gap when an output signal is present, and a control circuit which inhibits only one of two electronic counters.

    Abstract: In electro-discharge machining by using an electro-discharge machining electrode of a Cu(Ag)—W(Mo) material, the machining speed, the electrode wear ratio, and the surface roughness of a work piece are improved. For this purpose, to the Cu(Ag)—W(Mo) material, borates of an element selected from a group (M3) consisting of Mg, Ca, Sr, Ba, Sc, Y, and lanthanide and an iron group metal are added by appropriate amounts. As the borate compounds, particularly, it is preferred to use borate compounds expressed by M32B2O5 and M3B2O4.

    Abstract: A manufacturing method of a textured and coated electrode wire, comprising: selecting a copper-zinc alloy as a core material, preparing, by means of electroplating/hot-dipping, a metal zinc coating on a surface of the wire material, then performing pre-treatment on the coated electrode wire by means of discontinuous diffusion annealing to obtain a coated electrode wire material having a multi-layer structure of Zn/β-brass & γ-brass/α-brass, and then using multiple cold drawing treatments and a stress-relief annealing treatment to modify the electrode wire and obtain a textured and coated electrode wire material. Compared to conventional copper alloy electrode wires and zinc-coated electrode wires, the material has advantages of a fast cutting speed, low cutting cost, low environmental pollution, etc., wherein the cutting speed increases by 12% or more when compared with copper alloy electrode wire, the wire breakage rate during cutting processes decreases by 30%, and the replacement time interval of an ion-exchange resin filter for cooling water increases by 10%.

    Abstract: An electrode includes a metallic electrode body that has a surface region that is enriched in at least one of aluminum or chromium. The aluminum and/or chromium that is vaporized from the surface region suppresses vaporization loss of aluminum or chromium from the machined surface of the metallic workpiece during electric discharge machining.
