The Advantage Of Graphite Electrode Compared With Copper Electrode

Compared with copper electrode,graphite electrode has the following advantages:

1)Processing speed is faster

processing speed is the volume of metal removed per hour.the processing speed of graphite electrode is faster than copper electrode of 1.5 ~ 3 times,

graphite electrode can be worked at Large area Under the condition of high current,and copper electrode has low melting point,the current of copper electrode will be limited.

2)Resistance to wear and tear

machining accuracy is the outline dimension tolerance size after the workpiece machining,which is closely related Electrode material is resistant to wear and tear or not.

There are several kinds of edm, the electrode material will be dissipated;Such as volume loss,Loss of face,loss of side,end face and Angle loss when it is processed,the Angle of jiao electromagnetic field density is the largest,if experimenting on iron powder,it can be found most Angle of iron powder absorption.So in the above four kinds of loss, maximum Angle loss and Angle determines the service life of the electrode loss.so the final form is determined by the electrode Angle and the edge of the electrode loss,therefore,if the electrodes are the weakest parts,which can effectively resist wear and tear,electrode will have the longest life.

graphite electrode which is melting point 2000 ℃ higher than the copper and intensity is bigger than copper,so when it is processed,the Angle of loss is very small, which means that the superfine graphites service life is long,the processing cost is lower than copper electrode.
