  cnc engraving and milling machine wholesale is the use of continuous moving thin metal wire (called electrode wire) as electrode, pulse spark discharge on the workpiece to corrode metal, cutting molding. It is mainly used for processing a variety of complex shapes and precision fine workpieces, such as punching die, concave die, convex and concave die, fixed plate, discharge plate, etc., forming tools, templates, metal electrodes used in EDM forming processing, a variety of micro-holes, narrow slots, arbitrary curves, etc., with small processing allowance, high processing precision, short production cycle, low manufacturing cost outstanding advantages, It has been widely used in production. At present, cnc engraving and milling machine wholesale machines at home and abroad have accounted for more than 60% of the total number of electric machining machines.

  Briefly describe the physical principles of cnc engraving and milling machine wholesale:

  Free positive ions and electrons accumulate in the field and soon form an ionized conductive channel. At this stage, an electric current forms between the two plates. Resulting in numerous collisions between particles, forming a plasma region, and quickly rising to a high temperature of 8,000 to 12,000 degrees, melting some materials instantaneously on the surface of the two conductors, at the same time, due to the vaporization of the electrode and the dielectric fluid, forming a bubble, and its pressure regularly rises until it is very high. Then the current is interrupted, the temperature is suddenly reduced, causing the bubble to explode inside, and the generated power throws the dissolved material out of the crater, and then the corroded material recondenses into small spheres in the dielectric fluid, and is discharged by the dielectric fluid. Then the monitoring and control by NC control, the servomechanism is performed to make this discharge

  The phenomena are uniform.

  Depending on the speed of the electrode wire, cnc engraving and milling machine wholesale machines are usually divided into two categories: One is high-speed cnc engraving and milling machine wholesale machine (WEDM-HS), the electrode wire for high-speed reciprocating movement, the general wire speed of 8 ~ 10m/s, the electrode wire can be reused, high processing speed. However, rapid wire walking is easy to cause electrode wire jitter and reverse process and stop, so that the processing quality decreases. It is the main kind of the production and use in our country, it is also the cnc engraving and milling machine wholesale processing model in our country. The other is the low-speed cnc engraving and milling machine wholesale machine (WEDM-LS), the electrode wire for low-speed one-way movement, the general wire speed is less than 0.2m/s, the electrode wire discharge is no longer used, the work is stable, uniform, small jitter, good processing quality. However, the processing speed is low, and it is the main machine used in foreign production and use.
