Electrical Discharge Machining (EDM)

How to buy EDM machines from reputable suppliers or obtain EDM machining services from reputable service providers
By Howard Robertson When traditional machining methods fail to machine hard metals, you can opt for electrical discharge machining (EDM). One limitation of EDM is that you cannot use this method for machining non-conductive materials. There are two primary methods of EDM: wire EDM machining and sinker EDM machining (also called ram EDM).  

You can use electrical discharge machining in various industries including aerospace, medical, electronics and semiconductors. You can use EDM especially for steel, stainless steel, aircraft alloys, aluminum, precious metals and copper alloys.  

Some important parameters you must consider before carrying out the electrical discharge machining process are:  

1. The application for which you want to use electrical discharge machining
2. The metal on which you want to use EDM
3. The productivity of the EDM machine
4. The roughness of the surface of metal on which you want to use electrical discharge machining

Check out the electrical discharge machining services from reputable service providers

Once you have considered your requirements regarding EDM machining, you can go to reputable EDM machining service providers.
Try:  EDM Resources is one of the leading electrical discharge machining service providers. Minnesota Tool and Die Works is another leading service provider of EDM machining that provides wire EDM services. American Micro Products is a reputable service provider that offers precision manufacturing solutions including EDM services and small parts assembly and sub assembly. Volkert provides precision EDM machining services as well as wire and small hole EDM machining services. In addition, you can avail the services of C&H Machine, a reputable EDM machining service provider.

Buy a EDM machine from reputable suppliers

You can buy a new or used EDM machine from reputable suppliers.You can also opt for a used EDM machine that if you have any financial constraints.
Try:  Agie Charmilles is a global manufacturer of EDM machines that also supplies EDM accessories and customer support services. Hycon Corp. is a leading supplier of used EDM equipment. Another prominent supplier of used electrical discharge machining equipment is McWilliams Sales & Service. In addition, you can also buy used EDM equipment at MachineTools.com, a reputable supplier of used industrial equipment.

Buy components or materials for your electrical discharge machining equipment

If you want to buy materials or components for your EDM machines, you can check out the product line of some reputable suppliers.
Try:  You can buy EDM components such as graphite electrodes, tapping electrodes and wires at Saturn Industries, a reputable supplier of EDM materials. Another leading supplier of EDM components is Belmont Equipment & Technologies. You can also go to Sherbrooke Metals, a supplier of EDM machining electrodes. If you want to buy EDM electrode materials like tungsten composites, check products offered by Mi-Tech Metals, another reputable supplier of EDM materials. In addition, SGL Group supplies cut-to-size graphite, which you can use as electrodes for EDM.

• Always buy standard EDM equipment and components to ensure smooth functioning of your electrical discharge machining process.
• Ensure proper earthing to avoid accidents during EDM machining.
