There are many advantages such as no tool wear, no stress, good surface quality, and be able to machine the electric conductive materials regardless of their hardness and intensity.
In electrical machining, the microelectrode materials should have characteristics of good electrical conductivity and high rigidity.
The materials on the tungsten rod surface will dissolve layer by layer and finally a tungsten microelectrode with proper size will be obtained.
