graphite electrode grade hp factory
What are the characteristics of graphite electrode grade hp factory materials
Graphite electrode grade hp factory The graphite electrode grade hp factory produced by the manufacturer mainly has the following characteristics.
1. Fast speed;
The discharge speed of graphite is 2-3 times faster than that of copper, and the material is not easy to deform. It has significant advantages in the processing of thin-rib electrodes. The softening point of copper is around 1000 degrees, which is simply deformed by heating. The elevated temperature of graphite is 3650 degrees. At the mercy, in comparison, the thermal expansion coefficient of graphite materials is only 1/30 of that of copper materials;
2. Light weight;
The density of graphite is only 1/5 of that of copper. When large electrodes are used for electrical discharge machining, it can effectively reduce the burden of the machine tool (EDM), which is more suitable for the use of large molds;
3. the loss is small;
Because the spark oil contains C atoms, the high temperature causes the C atoms in the spark oil to be decomposed during electrical discharge machining, and a protective film is formed on the surface of the graphite electrode grade hp factory to compensate for the loss of the graphite electrode grade hp factory;
4. No burrs;
After the copper electrode is processed, it needs to be crafted to remove the burrs, and the graphite electrode grade hp factory has no burrs after processing, which not only saves a lot of cost and manpower, but also completes automated production more easily;
5. Easy to polish;
Because the cutting resistance of graphite is only 1/5 of that of copper, it is easier to perform manual grinding and polishing in operation;
6. Low cost;
Because the quotations of copper materials have been rising in recent years, the quotations of homogeneous graphite in all aspects are now lower than those of copper; the universality of Toyo Carbon under the same volume, the quotation of graphite products is 30 to 60% lower than that of copper. The quotation is relatively stable, and the fluctuation of short-term quotation is relatively small.
