Free positive ions and electrons accumulate in the electric field and soon form ionized conductive channels. At this stage, an electric current is formed between the two plates. It leads to numerous collisions between particles, forming plasma, which quickly rises to the high temperature of 8000 to 12000 degrees, instantly melting some substances on the surfaces of the two conductors.

At the same time, due to the vaporization of electrode and dielectric liquid, bubbles are formed, and their pressure rises regularly until it is very high. Then the current was interrupted and the temperature suddenly dropped, causing bubbles to explode inward.

The generated power throws the molten material out of the crater, and then the corroded material condenses into small balls in the dielectric liquid and is discharged by the dielectric liquid. Then through the monitoring of numerical control and the execution of servo mechanism, this discharge phenomenon is uniform.

As shown in the figure:

Improve the efficiency of pulse power supply of WEDM and reduce the overall energy consumption of equipment. The key point is to reduce the running speed of WEDM electrode wire and develop new EDM technology. Improve the machining accuracy of rough machining and reduce the number of trimming.

Improve the machining speed and accuracy of EDM cutting fine wire (below φ0. 1mm) of brass electrode wire, because it can replace thick wire (above φ0.2mm) in some application fields.

The above methods are very effective for improving processing efficiency. In addition, WEDM can be used as a machining center to realize the automatic exchange of electrode wires between rough machining and finish machining, and also to improve efficiency and reduce costs.
