White High Surface Quality And Extremely Hard Pe-300/pnr- 50 Electric Discharge Machine

EDM is a nontraditional precision machining method in which features are created by the controlled erosion of material on a usually conductive work piece using electrical discharges (sparks). Discharge of electricity Machining is based on a dielectric liquid, commonly deionized water or oil, separating two electrodes (one of which is the work piece). When the field intensity between the two electrodes is strong enough, the dielectric between them breaks down, current flows across, and material is drawn from both electrodes. The current between the electrodes is not constant; rather, it is intermittent, resulting in debris that is washed away by the fluid. This can be repeated numerous times to erode a finely controlled feature that would be impossible to accomplish with standard eroding techniques.
