cheap hp graphite electrodes
Introduction of cheap hp graphite electrodes
cheap hp graphite electrodes, mainly using petroleum coke and needle coke as raw materials, coal tar pitch as a binder, made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. They are made by electric arc in an electric arc furnace. According to its quality index, the conductor that releases electric energy to heat and melt the charge can be divided into ordinary power, high power and ultra-high power.
Advantages of cheap hp graphite electrodes
Note: Cheap hp graphite electrodes for EDM, also known as copper
1: The increasing complexity of mold geometry and the diversification of product applications have led to higher and higher requirements for the discharge accuracy of the spark machine. The advantages of cheap hp graphite electrodes are easier processing, high EDM removal rate, and low graphite loss. Therefore, some group-based spark machine customers abandon copper electrodes and switch to cheap hp graphite electrodes. In addition, some special-shaped electrodes cannot be made of copper, but graphite is easier to mold, and copper electrodes are heavier and not suitable for processing large electrodes. These factors have caused some group-based spark machine customers to apply cheap hp graphite electrodes.
2: Cheap hp graphite electrodes are easier to process, and the processing speed is significantly faster than copper electrodes. For example, the use of milling technology to process graphite is 2 to 3 times faster than other metal processing and does not require additional manual processing, while copper electrodes require manual frustration. Similarly, if the electrodes are manufactured by high-speed graphite processing*, the speed will be faster, the efficiency will be higher, and there will be no dust problems. In these processes, choosing tools with appropriate hardness and graphite can reduce tool wear and copper damage. If you specifically compare the milling time of cheap hp graphite electrodes and copper electrodes cheap hp graphite electrodes, graphite is 67% faster than copper electrodes. In general electrical discharge processing, the processing using cheap hp graphite electrodes is 58% faster than using copper electrodes. . In this way, the processing time is greatly reduced, and the manufacturing cost is also reduced.
3: The design of cheap hp graphite electrodes is different from that of traditional copper electrodes. Many mold factories usually have different allowances for roughing and finishing of copper electrodes, while cheap hp graphite electrodes use almost the same allowances, which reduces the number of machining operations. For this reason alone, it is sufficient Improve the accuracy of the mold cavity to a large extent.
