Process: Wire Erosion


Wire erosion (wire discharge machining, WEDM, wire-cut EDM) is a method to cut metal pieces with electric pulses. It is generally used to cut hard materials or fragile components.

The wire, also called the electrode, leads pulsing electrical charges through the workpiece. The electricity creates sparks that cut the material into desired shapes. Usually, it is possible to adapt the electrical sparks, high power means quick machining, while low power results in fine tolerances.

A dielectric fluid removes cut material and lower the negative heat effects. It is also common that the whole workpiece is submerged during wire erosion.

Wire erosion has some advantages compared to conventional machining. One is that the cutting tool pressure is low, allowing for small and fragile components to be machined. Another is that is possible to machine big pieces or hardened materials, which are difficult to machine.

Wire erosion is typically used when the geometry of the component is simple, for more complex pieces see spark erosion.

    Machining-Wire Erosion

    EDM wire erosion is required to extract tungsten carbide inserts from a free-issue drill bit for the mining industry. Having previously had this work completed in Chile, the client is now looking to return it to the UK and is keen to hear from suppliers who can assist. As well as having an immediate order to place, the client has advised that this will be repeatable work moving forward. **Due to the current health climate, we ask that you only submit a quotation for this project if you are in a position to fulfil the requirement.**

    Machining-Wire Erosion

    This new start-up company is looking for a supplier to manufacture this new design of stopper plate, which will become part of a paintball gun for the leisure industry. Quotes are sought for 50, 100, 200 and 3000 off. Good pricing per unit and overall quality/accuracy is vital for this enquiry. There is also opportunity for the manufacture of similar components, as well as further orders of this requirement going forward.

    Machining-Wire Erosion

    This company specialises in the bespoke designs of prosthetics and orthotics and has an order to place for these two designs of mild steel hinged jaws, which will be used as part of the elbow joint of a prosthetic arm. Quotes are required for 10 and 20 off of each jaw. Quality and accuracy of the finished product is of the utmost importance and pricing is also a key factor within this enquiry; once a relationship has been established, further projects could be made available in addition to this initial requirement.

    Machining-Wire Erosion

    This client is looking for a new supplier who can facilitate wire erosion of 1 off each of the two attached designs of mandrel as an initial request. Quality of the finish and lead times are the most important considerations - once proven, this project will then lead to single batch quantities of 50 to 100 off of varying sizes of mandrel per month. Therefore, this a great opportunity to fill ongoing capacity and grow your long-term customer base.

  5. Drawings count: 2

    Machining-Wire Erosion

    Urgent responses are sought by this Qimtek member, who seeks price and lead time indications for the two attached connection block parts. Both designs will be utilised within a construction application, with quotes required for 56 off of each. The connection block parts are to be wire eroded from duplex stainless steel and interested parties are advised that value and quality are of equal importance within this project. Those that would like to be considered for this enquiry are asked to make contact with the buyer at their earliest convenience.
