Graphite Electrode is a vital factor for the quality and performance EDM Electrodes. The hardness of the graphite electrode influences how fast it can cut metal and how easily it can withstand shock. In addition, its mechanical properties play a role. The EDM process can generate very violent sparks, which can damage or wear the electrode's surface. Its mechanical strength is therefore vital to ensure its longevity and effectiveness.
Graphite electrodes are typically made with a mix of carbon and materials to give them unique properties. The composition of graphite and the other material affects its overall hardness. Similarly, other variables such as the manufacturing process can affect the graphite electrode's hardness. Consider the following specifications to find the best graphite electrode for your application.
Whether you are looking for high grade or RP graphite electrodes, the quality of the raw materials plays an integral role in its final hardness. The higher grade graphite will perform better in demanding environments. This does not mean lower grades cannot produce quality metals, they simply cater to needs that are less demanding.
The electrical conductivity of graphite electrodes can vary widely depending on the raw materials used and the manufacturing process. In general, higher-graded electrodes will have a greater electrical conductivity than those of lower grade.
The diameter is a critical specification for an electrode because it directly affects the current carrying capacity and heat dissipation. It can also affect the stability of an electrode in an electric furnace. It is therefore advisable to select the largest diameter electrode possible to ensure maximum performance.
During the EDM, the electrode will rotate as it cuts the piece. The electrode will be under a lot of stress. Therefore, it is important to select a strong material. A good graphite electrode will have a low modulus of elasticity, which is the ratio of the force required to break an electrode against the change in length that the electrode can sustain before breaking. The lower modulus of elasticity is, the better an electrode will perform in the EDM.
