Answers to Your Wire EDM Services Questions

1. What is Wire EDM?

Wire EDM is electrical discharge machining. Instead of a standard cutting tool, it uses a thin piece of electrically charged wire with a dielectric fluid. This wire creates an intense spark which burns as it cuts, creating a smooth finish. In fact, there are no cuttings left behind. Wire EDM services from Roberson Machine Company can create a wide variety of patterns, shapes, and materials.

Roberson Machine Company works with many types of metal for wire EDM services. Almost any kind of electrically conductive metal is cut this way, and this includes brass, aluminum, carbide, and graphite materials.
