Graphite electrodes do have many advantages, but how to use them? How to improve efficiency, reduce costs and increase profits. Therefore, in the application of graphite materials, the following problems should be solved first:

First, dust. Because graphite has a fine particle structure, old dust will be generated during the production process, which has a great impact on the factory and the surrounding environment. The most important thing is the impact of dust on the equipment, because the conductivity of graphite is very good, if it enters the power box, it will easily cause short circuit failure. There are two solutions to this: one is post-oil processing, and the purchased graphite is soaked in spark oil for some time before processing. Graphite powder will not fly. The other is the upgrade of the machining center: the so-called upgrade is mainly to add a vacuum cleaner to the ordinary machining center.

Secondly, because graphite is relatively brittle, if graphite is processed by the method of processing copper electrodes (graphite is more brittle than copper), it is easy to cause electrical damage, especially when processing thin electrodes. In these processes, choosing tools and graphite with appropriate hardness can reduce tool wear and electrode damage. It is recommended to use the milling process to process graphite, and choose diamond tools or diamond-coated tools as much as possible.

Thirdly, the discharge treatment of the discharge gap: is different from copper, because the graphite electrode discharges faster, and more processing slag is corroded per unit of time, how to effectively discharge the slag becomes a problem. Therefore, the discharge gap is larger than that of copper. Generally speaking, when setting the discharge gap, the discharge gap of graphite is larger than that of copper.

Finally, get its drawbacks in perspective: Beyond dust, graphite leaves a few things to be desired. For example, in the processing of mirror molds, compared with copper electrodes, graphite electrodes are not easy to achieve the desired effect. To achieve a better surface effect, it is necessary to choose the finest graphite particles, and the cost of this graphite is often several times higher than that of ordinary graphite.
