[0002] The wire cut electrical discharge machine belongs to the electric processing category. Its working principle is that free positive ions and electrons accumulate in the field, and soon form an ionized conductive channel. In this stage, an electric current is formed between the two plates. Cause countless collisions between particles, form an ionized zone, and soon rise to 8000 to 12000 degrees of high temperature, and melt some materials on the surface of the two conductors at the same time. At the same time, due to the vaporization of the electrode and the dielectric liquid, a bubble is formed, and its pressure rises until very high. Then the current is interrupted, the temperature suddenly drops, causing the bubble to explode, generating power to throw the melted material out of the crater, and then the corroded material is recondensed into small spheres in the dielectric liquid and is discharged by the dielectric liquid. Then through the monitoring and control of NC control, the servo mechanism executes, so that the discharge phenomenon is uniform. The wire cut electrical discharge frock will produce high temperature in the cutting process, and needs to be cooled in the non-conductive deionized water coolant.
