Electrical discharge machining

Electrical discharge machining (EDM)

Electrical discharge machining, also known as spark machining or wire erosion, is an extremely accurate metal fabrication technique. Sparks are generated by an electric discharge, and each spark removes a tiny amount of metal through melting and evaporation. The spark wire varies in size but is always less than 1 micron in diameter, and since the wire is in constant motion during the EDM process, EDM causes less wear and tear on the cutting medium than other abrasion and machining processes.

“We have items that need to be delivered within 1 micrometer. Being able to deliver that, is very unique – but Koatek can do it.”

Customer statement

“From my point of view, our collaboration is world class. I can call at 3:30 PM with an acute problem, show up at Koatek the next morning – and within a day we have a solution.”

Advantages of Koatek EDM technology

There are a number of advantages to using EDM. Above all, the technique ensures a high degree of accuracy. It also enables us to produce workpieces in metals with difficult or “impossible” contours. What’s more, we can machine conductive materials, regardless of hardness – for instance, hard metals or hardened workpieces – to an accuracy of 0.001 mm. This results in highly accurate and uniform workpieces.

EDM experts

At Koatek, we are experts in electrical discharge machining. We have more than 20 years of experience in this technology and are one of the few machining companies offering EDM.

Thanks to our extensive expertise, we can handle a broad range of projects and ensure fully satisfactory results – every time!

More than a EDM supplier

In some cases, it is best to use EDM rather than conventional processing techniques.

We initially offered EDM as a sideline to more traditional, metal-removing turning and milling projects. Over the years, Koatek has evolved, and we now take on projects exclusively requiring EDM.

Koatek is therefore your go-to supplier if you solely need electrical discharge machining, but also if your workpieces require a combination of EDM, laser cutting, laser welding, laser engraving, turning and milling, or if you are looking for a turnkey service, including assembly, warehousing and next-day delivery.

You are welcome to contact Koatek for expert input to your next EDM project.
