Wire-cut discharge machining is a versatile precision machining process that can be used to manufacture complex shapes and geometrics. It is commonly used in the aerospace and medical industries where strict tolerances need to be met, and can also be used to manufacture hand plates or mass-produced parts.

With the expansion of industrial production scale and the development of manufacturing technology, wire cutting technology as a special processing technology, with its high processing precision, high production efficiency, low power consumption, low manufacturing cost characteristics, has been widely used in machining production. Especially in the mold processing industry, EDM technology is widely used in cold die and extrusion die processing, changing the past processing mode with separate die and curve grinding, shortening the manufacturing cycle, reducing manufacturing costs, and high precision.The process produces precise cuts by melting or vaporizing the material instead of removing it with a tool. Therefore, it can easily process parts features that are not suitable for traditional processing techniques. However, the parts must be electrically conductive.

Electrical discharge wire cutting (wire-walking) is an electrothermal production process that uses electrical discharge to remove material from the workpiece. It is an improvement on traditional EDM methods, is compatible with almost all conductive materials, and can be processed into complex designs and shapes. This article will discuss EDM, compatible materials and their applications in many industries.

Wire cutting is a non-contact reduction manufacturing process that uses charged fine wires and dielectric fluids to process metal parts into the desired shape.

2,Applications:

From hand plates to complete parts production processes, many industries use wire-cut discharge machining machines.

-aerospace industry

Wire-cut machining has very small tolerances and is the preferred machining process for aerospace parts manufacturers. This process, like the water knife cutting process, is especially suitable for parts that cannot withstand the high temperatures and stresses generated by traditional cutting tools.

Parts in the aerospace industry require excellent surface finish and precision. Manufacturers have been using wire-cut processes for years to make engines, turbine blades, landing gear parts, and more.

-medical industry

Wire-cut electric discharge machining machines can process complex parts with high precision and are suitable for all medical fields. In addition, metals that work well with wire-cut discharge machining services are also often used in the manufacture of medical devices.

Because the diameter of the wire determines the size of the incision, wire-cut machines can add tiny features to parts such as dental implants and syringe parts without compromising their structural integrity.

FAQ

-What other types of EDM are available?

In addition to Wire cutting discharge machining (Wire EDM), there are drilling discharge machining and sinking hole discharge machining. They differ in the electrodes they use. The electrode of drilling and discharging machining is tubular, which can process finer and deeper holes. Sink hole discharge machining, on the other hand, uses conductive metal to form a "positive electrode" of the desired shape.

-What is the difference between wire cutting and laser cutting?

Laser cutting uses a high-power thermal beam to cut the material, while wire-cut discharge machining uses the electrical processing of the workpiece of the wire.

-Why use deionized water in wire-cut discharge machining?

Deionized water has low carbon properties, which can be used as a coolant to regulate the dielectric temperature.
