Mirror spark machine is a kind of precision mold processing tool. Generally, it is not used for simpler processing.
For example, it is difficult to process or some molds that cannot be polished. Mirror spark machine is used because It can save several steps, thereby shortening the processing time.
- 1. The control circuit adds a special control function. If there is an arc fault or short circuit, the pulse power will immediately turn off the power to stop the cavity, the electrode temperature will not continue to rise, and the ignition will decrease.
- 2. X-axis side mirror machining spark opens the mold, high-precision mold, productivity can be much higher than Z-axis machining.
- 3. After high voltage failure, EDM adopts full low voltage pulse mode with the same pulse width. Practice shows that the pulse mode reduces the wear of the tool electrode, the roughness and uniformity of the machined surface, and the wear of the tool electrode is very small.
- 4. There are two mirror spark maintenance procedures, the side edge has a rectangular flat recovery, and the circular or elliptical plane cut surface adopts the bottom side recovery. During the lateral repair process, the electrode is inclined to the workpiece at a certain angle. At this time, the tool electrode is at the same time from the center to the outside, from the top to the bottom of the NC, that is, three-axis automatic control.
- 5. This kind of movement is not easy to accumulate carbon, discharge, and produce arcs, and has high production efficiency.
When the effluent is greater than the effluent, the effluent has a more stable and proper function, that is, the proper lifting knife is etched but not removed, and the shaped cavity is not etched inside. When the scale body is broken, if the scale body or the flow is greater than the output, the lifting knife will stop working and improve efficiency.
