Di-Spark, the EDM Company.

Di-Spark EDM (Electrical Discharge Machining)

Di-Spark Ltd have been an EDM company since the 1970’s when EDM technology was at the beginning of it’s modern, commercial development journey. The electrical discharge machining process was discovered way back in 1770 by Joseph Priestly, an English physicist, but wasn’t harnessed until the 1940’s when 2 Russian scientists discovered that EDM erosion processes (hence the terms, wire erosion and spark erosion) were better controlled submerged within dielectric fluid – (In modern EDM terms, a dielectric fluid is designed as a semiconductor with precise voltage and amperage conditions). This spurred development of the first EDM machine – which at the time was developed for machining materials such as Tugsten – a difficult-to-machine material. Spark erosion EDM arrived first, with wire erosion EDM following on during the 1960’s. EDM has a strong history in tool making, since it is ideal for cutting hardened materials for tools requiring longevity.

24/7 EDM Company

Since the 1970’s, electrical discharge machining has seen strong & ongoing technological developments, with current machines fully automated (CNC controlled) and capable of producing a component, part or sub-assembly to extremely fine tolerances. The EDM process itself has been harnessed and controlled to fine accuracy, and tooling is quick to change and setup. Running 7 days per week and around the clock, Di-Spark are an EDM company at the sharp end of precision machining, running AgieCharmilles EDM machining centres, now split into 2 separate cells: Wire erosion EDM and spark erosion EDM.

EDM For Difficult-To-Machine Materials

Machinability – as part of a specification can be a difficult balance to reach, on the basis that high technology industries require increasing levels of machining accuracy & quality within lean manufacturing parameters in order to remain competitive. Balancing these variables can be challenging, but Di-Spark, as an EDM company are well placed to advise & guide your component manufacture to leaner, higher quality manufacture by using the ‘right process for the right job’. EDM can, and often is used as a stand-alone machining process, but can equally be used on 5 axis machined parts which have subsequently been hardened and require internal detailing, profiling or hole drilling.
