EDM / Spark Erosion

The EDM Process was discovered in 1770 by an English Scientist Joseph Priestly, but not fully taken advantage of until 1943 by Russian Scientists. It was commercially developed in the mid 1970's and in the 1980's became widely available.

This is a manufacturing process for removing excess material often not accessible or achievable by conventional machining processes. The process is ideal for as well as manufacturing complex or short run components- Palletised loading systems.

A machining method typically used for hard metals. Electro Discharge Machining ( commonly known as EDM ) makes it possible to work with metals for which conventional machining techniques are ineffective, such as; titanium, hastelloy, kovar, inconel and carbide. EDM will only work with conductive materials. It is possible to cut small odd-shaped angles, detailed contours and produce angular holes & apertures.
