What is Wire-Electric Discharge Machining?

Wire cutting machining is to process parts through the discharge principle of electric spark. The workpiece is connected to the positive pole of the pulse power supply, use molybdenum wire or copper wire as the cutting wire, connect the metal wire to the negative pole of the high-frequency pulse power supply as the tool electrode, and use spark discharge to cut the machined parts. The pulse power supply provides processing energy, and the special wire cutting working fluid is used to remove the chips generated during the processing. Under the action of the electric field, the surfaces of the cathode and the anode are bombarded by the electron current and the ion current, respectively, so that an instantaneous high temperature heat source is formed in the electrode gap to melt and vaporize the local metal. The vaporized working fluid and workpiece material vapor expand rapidly in an instant. Under the combined action of this thermal expansion and the stamping of the working fluid, the melted and vaporized workpiece material is thrown out of the discharge channel, thus completing a spark discharge process. When the next pulse comes, continue to repeat the above spark discharge process to cut the workpiece into shape. The wire cutting trajectory is controlled through CNC programming to complete the final workpiece shape.

Why choose wire-electric discharge machining?

The quality of the machined surface is close to the grinding level, the wire cutting process is stable, uniform, with little jitter, good processing quality, and high production efficiency, which can reach 350/min. The wire cutting machine adopts the method of continuous wire feeding of electrodes, and the electrodes can be supplemented when they are lost, so the machining accuracy can be improved. The surface roughness value of the workpiece processed by the slow-moving wire cutting machine can generally reach Ra0.8μm and above. It can meet most of the workpieces with high hardness and ultra-high precision requirements.

What materials can be used for wire cutting?

Conductive metal and graphite can be used for EDM, common tungsten, brass, bronze, carbon, graphite copper, carbon steel, stainless steel, inconel alloy and so on.
