White High Accuracy And Easy To Operate Pe-200/pnr-20 Electric Discharge Machine

EDM is an unconventional precision machining technology that involves the controlled erosion of material on a normally conductive work piece utilising electrical discharges to form features (sparks). Electricity discharge A dielectric liquid, such as deionized water or oil, is used to separate two electrodes during machining (one of which is the work piece). The dielectric between the two electrodes breaks down when the field intensity between them is high enough, current flows across, and material is taken from both electrodes. The current between the electrodes is intermittent rather than constant, resulting in debris being washed away by the fluid. This can be done repeatedly to erode a finely controlled feature that would be impossible to achieve with traditional eroding methods.
