1. Working principle of high frequency electric spark machine tool
During the electric pulse processing, the electrode and the workpiece are respectively connected to the two poles of the high-frequency power supply, and the working fluid is the liquid sprayed by the universal magnetic nozzle. Through the gap automatic control system, the tool electrode is controlled to feed to the workpiece. When the gap between the two electrodes reaches the discharge distance, the pulse voltage applied on the electrode will break down the working fluid and generate electric spark discharge. At the moment of discharge, the arc generates a sharp high temperature and is accompanied by a pressure change, so that the metal material at this point immediately melts, vaporizes, and explodes into the working fluid, and condenses into small solid particles that are taken away by the working fluid. At this time, a pit is formed by electrolytic corrosion on the metal surface, the discharge stops, and the working fluid restores the insulation state. Immediately after the next pulse voltage continues to discharge, repeat the above process. Although there is very little metal corrosion in each pulse discharge, there are thousands of pulse discharges per second, which can quickly corrode metal and achieve a certain productivity. Under the condition of maintaining a constant discharge gap between the tool electrode and the workpiece, while electro-eroding the workpiece, the tool electrode is continuously fed to the workpiece, and finally the shape corresponding to the tool electrode is processed.
As a material for electrical discharge machining, tool electrodes are often selected from materials with good electrical conductivity, high melting point, easy processing and resistance to electrical corrosion, such as copper, graphite, and copper-tungsten alloys. When taking broken objects such as taps and other broken objects daily, preferentially use economical and easy-to-use brass materials to achieve good results. For example, the broken screw shaft can be processed with a hexagonal or flat-shaped electrode (the electrode is a brass rod), and the corresponding groove is processed, and then it can be removed with a wrench. For processing other broken tools, users can use them flexibly according to different shapes and sizes.
As the discharge medium, the working fluid plays a role in cooling and chip removal during processing. Therefore, media with low viscosity, high flash point and stable performance are commonly used, such as kerosene and purified water. In daily processing, kerosene can be used as a working fluid to prevent oxidation of aluminum parts; for iron, steel and other workpieces, clean tap water can be used to achieve good results.
