Technical Field

[0002] Wire cutting uses a continuously moving thin metal wire (called wire cutting electrode wire) as an electrode to perform pulse spark discharge to remove metal and cut the workpiece into shape. Free positive ions and electrons accumulate in the field and quickly form an ionized conductive channel. The current formed between the two plates causes countless collisions between particles, forming a plasma zone, which quickly rises to a high temperature of 8000 to 12000 degrees, instantly melting some materials on the surfaces of the two conductors. At the same time, due to the vaporization of the electrode and the dielectric fluid, a bubble is formed, and its pressure rises regularly until it is very high.
