Spark Erosion

Spark Erosion.

Newport Toolmakers are specialists in the technique of Spark Erosion, which enables us to manufacture extremely detailed and precision tools.

Electrical Discharge Machining (or EDM) is a machining method primarily used for hard metals or those that would be impossible to machine with traditional techniques. EDM can cut small or odd-shaped angles, intricate contours or cavities in pre-hardened steel without the need for heat treatment to soften and re-harden them as well as metals such as titanium, hastelloy, kovar, and inconel.

EDM is a method of removing material by a series of rapidly recurring electric arcing discharges between an electrode (the cutting tool) and the workpiece. The EDM cutting tool is guided along the desired path very close to the work but it does not touch the piece. Consecutive sparks produce a series of micro-craters on the work piece and remove material along the cutting path by melting and vaporization. The particles are washed away by the continuously flushing dielectric fluid.
