The Di-Spark Group supply subcontract, precision aerospace EDM machining. 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 erosion and spark erosion EDM machining to global aerospace standards, are highly certified to ISO9001, AS9100, Investors in people and SC21.
What is Electrical Discharge Machining?
Electrical Discharge Machining (EDM) as a process was discovered in 1770 by Joseph Priestly – an English scientist. Spark erosion electrical discharge machining, along with it’s sibling – wire erosion electrical discharge machining (also known as spark machining, spark eroding, burning or die sinking) is a 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 machining of hard materials
Another important advantage of electrical discharge machining over conventional machining is it’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 machined using electrical discharge machining, although ongoing research and development with EDM constantly expands it’s horizons in this regard.
The Di-Spark Group have been a global player in EDM since it’s first arrival
EDM wasn’t fully harnessed in any useful form until 1943, when Russian scientists achieved great success researching & developing electrical discharge machining. 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 machining ever since.
