EDMs abide by the principle of Electrolytic Corrosion to remove broken taps,reamers, drills, screws and so on ,no direct contact, thus, no external force and damage to the work piece; it also canmarking or dropping non precision holes on conducting materials; small size and light weight, shows its special superiority for large workpieces; working liquid is ordinary tap water, economical and convenient.

Portable EDM machine applies a magnetic base and a cross stand to support the head, it can be placed at any position, adjust the processing direction comprehensively. It can be applies on any size of work-pieces. Here are the schematic diagrams of processing methods.
