The EDGE2 machine brings an effective combination of high performance and versatility to Sink EDM operations. 

The EDGE2i machine brings an effective combination of high performance and versatility to Sink EDM operations. The EDGEi-Series machines are configured with many productive technologies to efficiently handle any task, and utilize the latest SuperSpark4 and IES (Intelligent Expert System) technologies. These advanced technologies provide intelligent adaptive power and jump controls to stabilize the EDM machining process and minimize electrode wear, and to drive optimum part quality results. The machine also features the leading-edge SuperSurface and SuperEdge generator technologies that produce uniform surface finish and metallurgical quality that are free from defects such as pin holes or pitting. 

The EDGEi-Series machines utilize a compact and space-savings design that incorporates the di-electric reservoir into the base casting, which improves thermal stability, and is standard with a di-electric chiller unit.  Machine positional accuracy is improved and maintained with the stationary work table construction, and excellent work zone access is provided to the operator with a 4-sided programmable rise and fall work tank.  The ATC (Automatic Tool Change) system is integrated into the machine structure and is located underneath the X and Y axes, and provides extended unattended machine operation. The EDGE2i is configured for safe and reliable unattended operation, and is equipped standard with an integrated Flame Sensor and Fire Suppression system.
