The Advantages of Graphite Electrodes Needing Attention:
1.The increasing complexity of mold geometry and the diversification of product applications lead to higher discharge accuracy requirements for spark machines. The advantages of graphite electrodes are easy processing, high removal rate of discharge processing and small graphite loss, so some group base spark machine customers give up copper electrodes instead of graphite electrodes. In addition, graphite electrode some special shape of the electrode can not be made of copper, but graphite is easier to form, and copper electrode heavier, graphite electrode is suitable for processing large electrodes, these factors cause some group of base spark machine customers to apply graphite electrode.
2.Graphite electrode is easier to process, and the processing speed is significantly faster than the copper electrode. For example, using milling process to process graphite, its processing speed than other metal processing faster than $number times and do not need additional manual processing, and copper electrodes need manual grinding. Similarly, if the use of high-speed graphite processing center to manufacture electrodes, the speed will be faster and more efficient, will not produce dust problems. In these processes, graphite electrodes to select the appropriate hardness of tools and graphite electrodes can reduce the wear and tear of the tool and copper breakage. If the milling time of graphite electrode is compared with that of copper electrode, the graphite electrode is 67% faster than that of copper electrode, and the process of using graphite electrodes is 58% faster than that of copper electrode in normal discharge processing. As a result, graphite electrode processing time is greatly reduced, but also reduce the cost of manufacturing.
3.The graphite electrode is different from the traditional copper electrode design. Many mold plants usually have different reserves in the roughing and finishing of copper electrodes, while graphite electrodes use almost the same amount of reserve, which reduces the number of CAD/CAM and machining times, which is why graphite electrodes are sufficient to improve the accuracy of mold cavities to a large extent.
