small graphite electrode

The superiority of today’s dry goods small graphite electrode

Note: Small graphite electrode for EDM, also known as Tonggong 1: The increasing complexity of the mold geometry of the small graphite electrode in Ulan Qab and the diversification of product applications have led to higher and higher requirements for the discharge accuracy of the spark machine . The advantages of the small graphite electrode are that it is easier to process, the EDM removal rate is high, and the graphite loss is small. Therefore, some group-based spark machine customers abandon the copper small graphite electrode and switch to the small graphite electrode.

In addition, some special-shaped small graphite electrodes cannot be made of copper, but graphite is easier to form, and copper small graphite electrodes are heavier and not suitable for processing large small graphite electrodes. These factors have caused some group-based spark machine customers to use small graphite electrode. 2: The small graphite electrode is easier to process, and the processing speed is significantly faster than the copper small graphite electrode. 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 the copper small graphite electrode requires manual frustration. Similarly, if a high-speed graphite machining center is used to manufacture the small graphite electrode, the speed will be faster, the efficiency will be higher, and there will be no dust problem.

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 the small graphite electrode and the copper small graphite electrode, the graphite is 67% faster than the copper small graphite electrode. In general EDM, the processing of the small graphite electrode is faster than the copper small graphite electrode. 58%. In this way, the processing time is greatly reduced, and the manufacturing cost is also reduced. 3: The design of the small graphite electrode is different from the traditional copper small graphite electrode.

Many mold factories usually have different allowances for roughing and finishing of copper small graphite electrode, while small graphite electrode uses almost the same allowance, which reduces the number of CAD/CAM and machining operations. The reason is enough to improve the accuracy of the mold cavity to a large extent. After the mold factory switched from the copper small graphite electrode to the small graphite electrode, the first thing that should be clear is how to use graphite materials and consider other related factors. Nowadays, some customers of group-based spark machine adopt small graphite electrode electric discharge machining with graphite, which eliminates the process of mold cavity polishing and chemical polishing, but still achieves the expected surface finish. Without increasing the time and polishing process, it is impossible to make such a workpiece with the copper small graphite electrode.

In addition, graphite is divided into different grades. The ideal machining effect can be achieved by using the appropriate grade of graphite and EDM parameters under a specific application. If the operator uses the small graphite electrode on the spark machine, the operator uses the same as the copper small graphite electrode Parameters, then the result must be disappointing. If you want to strictly control the material of the small graphite electrode, you can set the small graphite electrode in a non-loss state (loss less than 1%) during rough machining, but the copper small graphite electrode is not used.
