Electrical Discharge Machining (EDM)

Unmatched experience. World-class accuracy.

With 35 years of experience in EDM, Norman Noble leads the industry in EDM experience and capacity.

Electrical Discharge Machining (EDM) is used in medtech manufacturing for parts made from exotic materials with critical features that cannot be manufactured using traditional machine tool equipment. EDM is a non-contact machining process that provides accuracy and repeatability of +/-.0001”, and can be used in making recessed or angled cuts.

Norman Noble’s experience and capabilities with wire and conventional EDM is unmatched in the industry. As a known leader with 30 wire and plunge EDM machines, we provide exceptional accuracy and repeatability, specializing in machining components from exotic materials.
