Spark erosion (EDM) techniques can be used to machine even extremely hard materials such as hardened steel, titanium and hard metals. This is a thermal, erosive procedure: Electrical discharges occur between an electrode and the conductive workpiece that is to be machined. The flow of sparks detaches small particles from the workpiece and can be controlled precisely to give it the required geometry and surface
Erosion electrodes are produced using powder metallurgical techniques. From the powder through to the finished product, all the production steps are performed in-house and are subjected to ISO 9001:2000, AS/EN/JISQ 9100 and our own rigorous quality standards.
Benefits during the machining of steel and hard metals
- High wear resistance
- Extremely sharp contours
- High surface quality
- Very good machinability
- Improved environmental and working conditions
