EDM basic physical principle is the presence of free positive ions and electrons to accumulate, and soon to be
ionized to form a conductive channel. At this stage, a current between two plates. Lead to numerous collisions
between particles occur, forming a plasma, and soon increased to 8000 to 12,000 degrees Celsius, melting
moments in the two conductors, some of the material at the same time, the electrode and dielectric fluid
vaporized, forming a bubble, the rules and it increased until the pressure is very high. And current interruption,
the temperature suddenly drop, causing the bubble implosion, the momentum generated to melt the material
thrown into the crater, and then the material is corrosive fluid in the dielectric recondensed into a small ball,
and was discharged dielectric fluid. NC controlled then the monitoring and control, servo bodies, so that the
phenomenon of uniform discharge to achieve the processing of materials to be processed, making it meet the
requirements of size and shape precision products.
