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

    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.

    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.

  3. Drawings count: 2

    Machining-Wire Erosion

    Wire erosion of a selection of parts is needed, with delivery sought by the 23rd July. The client would like to hear from those that are able to meet this deadline, whilst also offering high quality and good value. The components in question will be utilised within a construction application, with quotes required for 210 off of each at this time.
