What Should I Pay Attention To When Choosing Graphite Electrode Products?

The graphite electrode material can be divided into different proportions according to its particle size. Of course, for users, the choice of graphite electrode material is very critical, because it directly affects the speed of electrical processing, so it must be based on different processing Circumstances, choose a good graphite electrode material.

We know that the melting point of graphite electrode is extremely high, because it has extremely high heat resistance, can increase the current value, reduce the loss of the electrode, thereby further improving the production efficiency; and when the current value is very small, the loss of the electrode is Will increase. When the area remains the same and the pulse width remains the same, the peak current will reach a certain value and continue to increase, and then the process will become unstable. The electrode and the process will produce arc burns, which will greatly reduce the production efficiency.

The larger the current of the graphite electrode, the larger the pits of electric corrosion, so as the peak current increases, its surface will become rougher and rougher. At the beginning, the thin electrode almost touches the workpiece to discharge. The small electrode cannot withstand excessive current and is easily damaged. Therefore, the current should be lowered at the beginning, and then the peak current should be increased slowly until the discharge is stable and the processing speed is fast.
