Advantages Of Graphite Electrode

Advantages Of Graphite Electrode

1: the increasing complexity of mold geometry and the diversification of product applications lead to higher and higher requirements for the discharge accuracy of the spark machine. The advantages of Graphite Electrode are easy to process, high removal rate of discharge machining, and small graphite loss. Therefore, some customers of group based spark machine abandoned copper electrode and changed to graphite electrode. In addition, some special shaped electrodes cannot be made of copper, but graphite is easier to form, and the copper electrode is heavy, which is not suitable for processing large electrodes. All these factors lead to the application of graphite electrode for some group based spark machine customers.

2: graphite electrode is easier to process, and the processing speed is significantly faster than that of copper electrode. Graphite, for example, is processed by milling at a rate of two to three times faster than other metals and requires no additional manual processing, while copper electrodes are ground by hand. Similarly, if the electrode is made in a high speed graphite processing center, it will be faster and more efficient without creating dust problems.

3: Graphite electrode is different from traditional copper electrode in design. Many die factories usually have different reserves for rough machining and finishing of copper electrodes, while graphite electrodes use almost the same amount, which reduces the number of CAD/CAM and machine machining. For this reason alone, it is enough to greatly improve the precision of mold cavity.

HP Graphite Electrode has superior properties that copper cannot match:

Machining speed: high speed milling rough machining 3 times faster than copper; High speed milling finishing is 5 times faster than copper

Good machinability, can achieve complex geometric modeling

Light weight, less than 1/4 of the density of copper, easy to clamp electrode

The number of individual electrodes can be reduced because they can be bundled into a composite electrode

Good thermal stability, no deformation and no machining burr.
