Revealing the new material of hp 650 graphite electrode

hp 650 graphite electrode new material

Graphite has the advantages of light weight, strong resistance to current, and low electrode wear. It is very suitable for the manufacture of precision molds in the automotive industry. Electrode graphitization is one of the development trends of EDM technology.

hp 650 graphite electrode has the advantages of easy processing, high metal removal rate and low graphite loss. Therefore, more and more mold factories abandon copper electrodes and use hp 650 graphite electrode instead. In addition, some shapes of electrodes cannot be made of copper, but graphite is easier to form, and copper electrodes are heavier, which is not suitable for processing large electrodes. These factors have promoted the wider application of hp 650 graphite electrode in the mold manufacturing industry.

After the copper electrode is transferred to the hp 650 graphite electrode in the mold factory, it should be clear how to use graphite materials and other related factors.

Graphite can be divided into different grades. In special applications, proper graphite grades and mechanical parameters can achieve ideal processing results. If the machine operator using the hp 650 graphite electrode uses the same parameter settings as the copper electrode, the result is disappointing, because the melting point of copper is 1083°C, while graphite sublimates at 1083°C, so the hp 650 graphite electrode can withstand more The machine setting conditions. If the electrode material is strictly controlled, the hp 650 graphite electrode can be set in a lossless state (loss less than 1%) during rough machining, but copper electrodes are not used.

The hp 650 graphite electrode is easy to process. For example, the milling speed of graphite is 2-3 times faster than other metals and does not require additional manual processing, while copper electrodes require manual grinding. Similarly, if a high-speed graphite machining center is used to manufacture electrodes, the speed will be faster, the efficiency will be higher, and there will be no dust problems. In these processes, choosing the right hardness tool and graphite can reduce tool wear and electrode damage.

The design of the hp 650 graphite electrode is also different. In the rough machining and finishing of copper electrodes, many mold factories often have different reservations, and the hp 650 graphite electrode uses the same reservations, which reduces the number of CAD/CAM and processing. For this reason alone, it is enough to improve the accuracy of the cavity to a large extent.

At present, most plastic products are processed by special graphite EDM, which avoids the process of mold cavity polishing and chemical polishing, but still achieves the expected surface finish. If you do not increase the time and polishing process, it is impossible to manufacture such a workpiece. Compared with copper electrodes, the milling time of hp 650 graphite electrode and copper electrode is 67% faster than that of copper electrode. Generally speaking, the processing time of the hp 650 graphite electrode is 58% faster than that of the copper electrode, which greatly reduces the manufacturing cost.

Full hp 650 graphite electrode EDM has many advantages. Therefore, many mold factories are gradually transforming to hp 650 graphite electrode EDM to improve the market competitiveness of enterprises and products.
