USED CNC ELECTRONIC DISCHARGE MACHINES (EDM)
What They Do: Electrical discharge machining goes by many names, such as spark eroding, die sinking, spark machining, burning, wire burning, etc. There are also two different types of used CNC EDMs: used wire EDM and used sinker EDM.
The used EDM process is defined by removing material from a workpiece by a series of rapidly recurring current discharges between two electrodes. These electrodes are separated by a dielectric liquid that enhances electric voltage.
The main difference between used wire and used sinker EDM is that in used sinker EDM, the material is submerged in an insulating liquid, and in used wire EDM a single-strand brass wire is submerged and used to cut the workpiece.
Benefits of Used CNC EDMs:
- Creates complex shapes that would otherwise be difficult to produce
- Ideal for small workpieces that could be damaged by tool pressure
- No direct contact between tools and workpiece
- Popular used CNC EDM Brands: Makino EDM, Sodick EDM, Agie Charmilles EDM, Mitsubishi EDM, Accutex EDM, Ona EDM and Fanuc EDM
