Leading Wire EDM Companies

The electrothermal production process called wire EDM (Electrical Discharge Machining) uses a thin, single-strand metal wire and de-ionized water to cut through metal while preventing rust. Since the wire and the workpiece are not in direct contact during the wire-cutting process, the material’s shape and the wire’s course can be machined without being altered. Read More…

The wire is very quickly charged to the desired voltage to do this. De-ionized water surrounds the wire as well. A spark jumps the gap when the voltage is at the proper amount, melting a small workpiece area. The de-ionized water cools and removes the tiny particles from the gap by flushing them out. As a result, the workpiece material's hardness has no negative impact on the cutting speed. Wire cutting is frequently used to manufacture extrusion dies and blanking punches. In wire electrical discharge machining (WEDM), a thin electrode wire that follows a precisely programmed path is used to cut or shape a workpiece, frequently made of conductive material. Although smaller and bigger sizes are available, electrodes typically have diameters between 0.004" and 0.012" (0.1 mm and 0.3 mm).

Wire Electrical Discharge Machine

How WEDM works

An EDM machine always cuts the entire workpiece. A hole in the workpiece is required before beginning wire machining, unless the process starts from the edge. Each discharge on the machining region leaves a crater in the workpiece and an impression on the tool. It is possible to create pieces with taper or various profiles at the top and bottom thanks to the wire's ability to incline. The electrode and workpiece never make contact mechanically (see above).

The wire typically has a diameter of between 0.1 and 0.3 mm and is constructed of brass or layered copper. Depending on the accuracy and surface polish required, a part may be cut, roughed, or skimmed. On a single cut, the wire should ideally go through a solid component before dropping a slug or piece of scrap. This will provide adequate accuracy for some tasks, but skimming is usually required.

Components of WEDM

  1. CNC Tools -CNC tools manage the entire Wire EDM machining process. Controlling the entire procedure entails being able to handle the cutting process automatically and sequence the wire path.
  2. Energy Source -The power supply unit is the part that sends pulses to the wire electrode and the workpiece. It also regulates the quantity and intensity of electrical charges that travel through the wire electrode and come into contact with the workpiece.
  3. Wire -To produce the electrical discharge, the wire acts as the electrode. The workpiece's thickness and form directly impact the wire's diameter. Typically, wires with sizes between 0.05 and 0.25 mm can be used.
  4. The most common types of wires include:
  5. Dielectric Medium -Dielectric fluid must be present in the tank where the wire-cut EDM procedure is performed. With the help of this liquid, the workpiece's minute particles are kept from adhering to the wire electrode. De-ionized water is the most used medium since it cools the process and produces a workpiece with a smooth surface.
  6. Electrodes -The wire (cathode) and the workpiece serve as the machine's electrodes (anode). The servo motor controls the wire electrode, ensuring that it never makes contact with the workpiece while cutting with wire EDM.
Wire EDM Process

Materials That Can Be Cut Using EDM Wire

The EDM wire method can cut any conductive material, including steel, titanium, aluminum, brass, and superalloys. Due to its accuracy, the EDM wire-cut technology has established itself as a standard cutting method across all industries. EDM wire makes cutting and creating metal machine parts, logos, and other objects simple. The thickness, dimension, and length of the item to be cut determine how much EDM wire will be needed to produce the part or its prototype.

Wire Electrical Discharge Machining

Applications of WEDM

Many industries employ wire EDM machining because it is adaptable and can cut both ferrous and non-ferrous metals. Additionally, because it can process lengthy and extremely small pieces, size and shape allow its use. But because the thickness of the wire electrode influences the use of a wire EDM machine, conventional EDM may work with harder and thicker materials.

Advantages of WEDM

  • Create patterns or designs that would be difficult to make with traditional cutting tools, whether simple or complex.
  • CNC-controlled cutting patterns can be quickly finished on various stainless steel alloys while keeping a low Ra surface roughness.
  • High dimensional accuracy for pieces that fit together tightly
  • The procedure produces a few burrs.
  • Typically, custom tooling is not required.

Choosing the Correct Wire EDM Company

For the most positive outcome when selecting a wire EDM company, it is important to compare several businesses using our directory of wire EDM businesses. Each wire company has a business profile page highlighting their areas of experience and capabilities, along with a contact form to directly communicate with the company for more information or request a quote. Review each wire EDM business website using our patented website previewer for an idea of what each company specializes in. Then, use our simple RFQ form to contact multiple wire EDM companies with the same form.
