EDM MACHINING

EDM MACHINING

EDM is one of the most accurate manufacturing processes available for creating complex or simple shapes and geometries. EDM works by eroding material in the path of electrical discharges that form an arc between an electrode tool and the work piece. EDM manufacturing is quite affordable and a very desirable manufacturing process when low counts or high accuracy is required. Turn around time can be fast and depends on manufacturer back log.

The EDM system consists of a shaped tool, an electrode, and the part. The part is connected to a power supply. To create a potential difference between the work piece and tool, the work piece is immersed in a dielectric (electrically nonconducting) fluid which is circulated to flush away debris.

The cutting pattern is usually CNC controlled. Many EDM machine electrodes can rotate about two-three axis allowing for cutting of internal cavities. This makes EDM a highly capable manufacturing process.

Some common EDM machining services that we provide include: assembly services, just-in-time delivery, prototype services, machine shop services, short run services, high quantity production, CAD / CAM support, and reverse engineering.
