Sub-Contract Electrical Discharge Machining at Di-Spark Ltd

EDM Components: Machining Videos

The Di-Spark Group supply subcontract, precision aerospace EDM components. Our facility covers 20,000 square feet, we employ over 40 people and are within an hours drive of both Heathrow/Gatwick airports and Southampton container port. We operate 24/7, offer wire eroded and spark eroded EDM components machined to global aerospace standards, we are certified to ISO9001, AS9100, Investors in people and SC21.

EDM Components

Electrical Discharge Machining (EDM) as a process was discovered in 1770 by Joseph Priestly – an English scientist. Wire erosion electrical discharge machining, along with it’s sibling – spark erosion electrical discharge machining (also known as spark machining, spark eroding, burning or die sinking) is an Electrical machining process for removing excess material inaccessible to conventional machining, making EDM an intelligent choice for complex geometric, prismatic and precision components. EDM will also handle the cutting of unusual angles, detailed bevels and the machining of deeply embedded holes & apertures.

Advanced EDM Components: hard materials

Another advantage of electrical discharge machining & manufacturing EDM components over conventional machining is EDM’s ability to handle hard metals such as titanium, hastelloy, kovar, inconel and carbide. It is also important to note that due to the very nature of the EDM process, only conductive materials can be machinedg, although ongoing research and innovation with EDM constantly expands it’s horizons in this regard.

Di-Spark Ltd: A global player, producing EDM components since the 1970s

EDM wasn’t fully harnessed in any useful form until 1943, when Russian scientists achieved great success researching & developing EDM. EDM crossed into commercial territories during the 1970s and Di-Spark invested in the new technology straight away – one of the first companies into the UK to do so, and we have been at the forefront of precision EDM component machining ever since.
