Background technology
WEDM (Wire cut Electrical Discharge Machining is called for short WEDM), belong to electric machining category, when studying switch contact by the phenomenon of spark discharge corrosion and damage and reason by former Soviet Union La Zhalinke Mr. and Mrs, find that the TRANSIENT HIGH TEMPERATURE of electric spark can make the metal molten of local, oxidation and being corroded, thus started and invented electric discharge machining method.Operation principle is that free cation and electronics accumulate in field, forms a conductive channel be ionized very soon.In this stage, between two plates, form electric current.Cause occurring between particle to collide many times, form an ion plasma, and be elevated to the high temperature of 8000 to 12000 degree very soon, at two some materials of conductive surface instant melting, meanwhile, due to the vaporization of electrode and electrolyte, form a bubble, and its pressure rule rises until very high.Then current interruptions, temperature reduces suddenly, causes bubble implosion, and the power of generation is dished out the material dissolved crater, and the material be then corroded regelation in electrolyte becomes little spheroid, and is drained by electrolyte.Then the monitoring controlled by NC and management and control, servo control mechanism performs, and make this electric discharge phenomena uniformity, thus it is processed to reach machining object, makes it the product becoming size and the form accuracy meeted the requirements.
China produces and the overwhelming majority of use is High-speed Wire Electro-Discharge Machine, High-speed Wire Electro-Discharge Machine is as the original creation technology of China, become one of machine that in China NC Machine, output is maximum, most widely used, along with the develop rapidly of China's die industry, WEDM is had higher requirement, thus also further promotes the development of Electric Discharge Wire-cutting Technology.
But in high-speed electric spark Linear cut process, because guide wheel runs up and periodically commutation, wire electrode is easily shaken, and makes wire electrode locus in working region unstable, thus can cause Workpiece Machining Accuracy and crudy poor.
Utility model content
