Go wire electrical discharge line breakdown of wire electrode is running fast reciprocating, wire electrode in the machining process repeated use. So this kind of wire electrode mainly molybdenum wire, tungsten bars and tungsten molybdenum wire. With molybdenum wire in the specifications for (0.1 ~ 0.18) mm. When to cut the small round or sew the slot, can also be used Ø 0.06 mm of molybdenum wire, tungsten corrosion resistance, high tensile strength, but is crisp and not resistant to bend, and because the price is expensive, and is used in exceptional cases.
Take care silk edm cutting machine generally with the yellow wire do wire electrode. Wire electrode do one-way low speed running, once is rejected, so don't have to use high strength of molybdenum wire. In order to improve the cutting performance, home and abroad have developed wedm dedicated copper wire electrode, which have a plenty of for the yellow copper wire, the low melting point of plating zinc alloy, in fire has larger vaporization discharge explosion, the linear cutting speed is higher, specifications for Ø (0.10 ~ 0.30) mm. Similarly, in cutting fine seam tank and requirements for the low round, can use tungsten or molybdenum wire, minimum diameter can be up to 0.02 ~ 0.06 mm.
