In recent years, with the precision molds and efficient Die (Die cycles become shorter and shorter) introduced, and people die production becoming more demanding, because all the copper electrode own conditions, mold has become increasingly unable to meet requirements of the development of the industry. EDM as graphite electrode materials, cutting its high, light weight, forming fast, minimal swelling, and loss of small.
Dressing the advantages of easy, in the mold industry has been widely used to replace the copper electrode has become inevitable.
Graphite electrode material properties
1. CNC processing speed, high cutting repaired easily Graphite machining speed, the copper electrode 3 to 5 times, finishing speed is particularly conspicuous, and its high strength, ultra-high (50 to 90 mm) and thin (0.2 ~ 0.5 mm) electrode, processing of difficult deformation . And in many cases, products need to have a good effect profile, which requires doing electrode made possible when the overall public electrode, and the overall production at the electrode There are all kinds of hidden-Kok, graphite-dressing characteristics, making the problem is easily solved, and greatly reduce the number of the electrode and copper electrode is not able to do.
2. Rapid EDM forming, thermal expansion of small, low loss because the conductivity of the graphite better than copper, its discharge rate faster than copper, copper for 3 to 5 times. And the discharge current can bear to live large, EDM rough when more favorable. At the same time, the same size, weight graphite copper 1 / 5 times, greatly reducing the load EDM. For large-scale production of the electrode, electrodes strong competitive advantage in the overall public. Graphite sublimation temperature in 4200 °C for copper 3 to 4 times (copper sublimation temperature of 1100 °C). Under high temperature and deformation small (under the same conditions as copper electrical 1 / 3 to 1 / 5), not softened. Can be high efficiency, low power consumption and discharge energy will be transmitted to the workpieces. Because graphite under high temperature strength has actually strengthened, can effectively reduce the discharge loss (graphite loss of copper 1 / 4) to ensure that the processing quality.
3. Light weight, low cost the production costs of a mold, electrode CNC machining time, EDM, electrode wear and tear of the vast majority of the overall costs, and these are from electrode material by the decision itself. Graphite and copper compared to the graphite EDM machining speed and the speed of copper are 3 to 5 times. At the same time, wear minimal and the overall public of the production of graphite electrodes can reduce the number of electrodes, the electrodes will reduce supplies and machining time.
