    What is EDM engineering?

    Electrical discharge machining (EDM engineering) is a manufacturing process that uses electrical sparks to cut into metal. We provide EDM engineering to high-profile companies in Defence, Medical & Pharmaceutical, Space and Motorsport industries. There are several types of EDM engineering…

    Wire EDM Engineering

    Using a wire as the tools electrode, Wire EDM engineering prevents the material from eroding from the wire itself by continually switching. The process of wire EDM engineering is particularly suited to tough materials such as Inconel and hardened tool steels.

    How does Wire EDM engineering work?

    Where the quality of finish is paramount, Wire EDM engineering machinery utilises several minuscule cuts or ‘skims’ of the part removing microns of material at a time. This process is particularly useful for the manufacture of intricate, complex parts where a high degree of accuracy is required.

    Micro Precision EDM Engineering

    Using a micro ‘fine’ wire as the tool, Micro Precision EDM engineering is particularly suited to tough materials such as Inconel and hardened tool steels. It can also be used to cut parts made from tungsten carbide, titanium, aluminium, copper and other more exotic alloys providing that the material is electrically conductive.

    Spark Erosion/Die Sink EDM Engineering

    Spark erosion is where an electric spark between 8,000-12,000 °C is created between an electrode and the workpiece. This effectively vaporises the material to create the required design. Our Charmilles Roboform 350 machine combines high-speed finishing, and micro and automated tool changer capability thus speeding up the production process. Lower electrode wear also keeps down the cost of the product.

    Our State-of-the-Art EDM Engineering Machinery

    Our GF machinery CUT 1000 machines are a benchmark in microwire erosion. Using wires of 20 μm, surface finishes of Ra 0.05 μm, 11 μm inside radii, 22 μm slits are now achievable. Production of both small and high-volume batches of components means that EDM engineering is of real benefit in the manufacture of several technologies such as medical components, automotive, aerospace and more.

    What are the benefits of EDM engineering?

    Difficult-to-Machine Materials

    EDM engineering is particularly suited to difficult-to-machine, tough, materials such as Inconel and hardened tool steels. The process is accurate and won’t compromise the surface finish of the resulting products.

    Quality Finishes

    As it is a non-contact manufacturing process, EDM engineering achieves high-quality finishes. This means that the need for post-processing procedures and surface treatments will be greatly reduced.

    Quick Turnaround

    Our machinery can run 24 hours a day, 7 days a week, allowing for very competitive pricing and quick turnaround times. Whether you require small or high-volume batch work, one-off products or prototypes, we can help with it all.


    Our state-of-the-art machinery and automated software allow us to produce intricate, complex parts where a high degree of accuracy is required. Furthermore, our results are predictable and repeatable during every production run.

    Tight Tolerances

    We work with a range of industries where tight tolerances are essential. Our EDM engineering machinery can accommodate intricate, complex parts, down to 20 microns in size with tolerances of less than 3 microns.
