Mirror spark machining is a very important equipment in the mold manufacturing industry.
Each mold cannot be processed without its processing at the factory, and the mirror spark machine has an unshakable position in the mold manufacturing industry.
Today I will tell you about it. Some advantages of mirror spark machine.
- 1. There are two side repair procedures for mirror spark machine. The rectangular corner is a flat side restoration plan, and the round or multi-face ellipse uses a flat bottom side restoration plan. During the side repair process, the electrode moves toward the workpiece at a certain angle. At this time, the tool electrode moves from the middle to the outside, from top to bottom at the same time, and is automatically controlled by CNC, that is, the three-axis connecting rod. This type of movement is not easy to deposit carbon, easy to exhaust and exhaust, does not produce arcs, and has high production efficiency.
- 2. The X-axis horizontal machining of the mirror spark machine has a high precision of closing the mold, and the productivity can be much higher than that of the Z-axis machining.
- 3. The electrode can be used for rough and fine machining with a CNC EDM, which saves the manufacturing time and cost of the double electrode, saves the trouble caused by the correction of the fine machining electrode, and shortens the mold manufacturing time.
- 4. The EDM machine tool adds special control to the control circuit. When an arc or false short circuit occurs, immediately cut off the pulse power supply and stop supplying power to the cavity. The electrode temperature will not continue to rise and the fire will be reduced.
- 5. EDM adopts complete low-voltage pulse mode after high-voltage breakdown, with the same pulse width. Practice has proved that this pulse mode further 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.
- 6. The self-appropriate function, that is, the self-appropriate lifting knife, is that when the discharge is more stable than the generated discharge, the cavity is not corroded and cleaned. When the discharge is greater than the discharge, the shape cavity is not etched, that is When the balance is broken and the balance or discharge is greater than the production, the lifting knife stops and the efficiency is improved.
