With the continuous development of our country industry, the development of the Graphite Electrode in the market more and more widely, and gradually occupied the leading position in the market, however, when selecting a Graphite electrode material, should be how to choose the right?
Graphite electrode material according to its size, the proportion can be divided into different grades, of course, for users, when the choice of graphite electrode materials is very crucial, because it directly affects the machining speed, so, according to the different processing conditions, choose high quality graphite electrode material.
We know that the graphite electrode has a very high melting point, because it has extremely high heat resistance and can greatly reduce the loss of the electrode and thus further improve the production efficiency. When the current value is small, the electrode loss increases. And when the area is constant, pulse width is constant, the peak current will reach a certain value, continue to increase, and then, the phenomenon of the processing is not stable, electrode and processing can produce arc burns, it will greatly reduce the production efficiency.
The larger the current of the graphite electrode, the larger the cavitation pit, so the surface becomes rougher as the peak current increases. Beginning of wafer electrodes is almost contacts artifacts in discharge, small electrode had to bear the strong current, easily damaged, so the beginning should keep the current, and then slowly turned big peak current until discharge stability, processing speed is the fastest.
Graphite particles determines the size of the degree of loss, the bigger the particles, the greater the loss of the small dissipation degree the smaller particles, graphite particles also determines the roughness of the surface, so in the choice of graphite electrode materials, must be careful attention.
