Red copper: electrolytic copper forged without impurities is the best.;
Graphite: Fine-grained dense, isotropic high-purity graphite.
Copper:
Graphite:1. Large loss of finishing electrode.;
Red copper: 1. After being used, it can be reused after restructuring, with high utilization rate.
Graphite:
Copper:
Graphite:
Immerse the graphite in spark oil for a period of time before processing the electrode, and the chipping angle can be significantly improved.

Graphite is cheap, and copper electrodes are durable but expensive.
Graphite:
Red copper: fine processing, mirror processing.
Graphite: rough machining, thin and deep bone machining.
Graphite is easy to process, and the processing efficiency is at least three times higher than that of copper, and the discharge speed is much faster than that of copper.As a mold with high efficiency and short delivery time, graphite is the development trend.
1. Electrode design
2. Electrode processing and production
3. Light weight, its density is less than 1/4 of copper
4.EDM
First of all, graphite and copper are compared in terms of materials: graphite is light and brittle, and copper is tough and heavy.
The discharge capacity of the two is determined according to the size of the electrode. Under normal circumstances, the spark level of the larger electrode is larger. In general, the precision is 0.03-0.1mm. The material selection should be based on the actual situation, and each has its advantages: In terms of small ribs, graphite is easy to deform during processing. Copper will be deformed and difficult to process. In terms of large electrodes, the difference between the two is weight. The damage to CNC is larger than that of copper, because graphite is produced It is powder, which is extremely harmful to the CNC track. At this time, it is necessary to protect it, and the sheath of the vacuum cleaner and the guide rail must be added. Copper is generally selected as copper as the electrode.
Graphite electrode is a kind of granular structure, and it cannot be processed into a mirror surface. If you want to process a mirror surface, the best is the copper electrode. There are also graphite electrodes that generally do not need to be polished. The processing speed of graphite electrodes is fast but the surface roughness is not as good as that of copper electrodes. Graphite electrode consumes a lot. Generally, the graphite electrode of the mold parts is rough and the red copper electrode is refined, so I personally think it is more ideal. The graphite electrode has better cutting performance for CNC machining than the copper electrode. There is a special CNC machine for graphite CNC machining. Taiwan. The common gap of graphite electrode is 0.11mm 0.08mm 0.03mm
