EDM carbon slag and slagging
Only actively create a good exclusion of the conditions, symptomatic to take some way to actively deal with.
Another reason for the exclusion of carbon residue is the complexity of the machined surface, so that the chip path is not smooth.
In practice, often at the expense of processing speed to remove carbon slag, for example, in the middle of the use of high voltage, large stop pulse and so on.
EDM machine in the production of carbon residue and the exclusion of carbon residue balance conditions can be carried out smoothly.
