The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?
I had worked on graphite electrodes for 3 years before, and the fact told me that in addition to using the wind to remove the powder, the others were ineffective or disorderly. Because you have to measure size while processing.
In addition, the infiltration of water on graphite is not good, can not get the effect of dust removal. Now there are special graphite machine, sealing system. Air-cooled can be used, after all, the best air-cooled.
Use oil cold. Air cooling will cause graphite dust flying, on the one hand, toxic, on the one hand there are security risks (caused by circuit short circuit). Water cooling is virtually out of use, taking into account the maintenance and maintenance of the CNC.
Of course you do is oil cold if not toxic cooling but although graphite powder lubrication seems to have damage to the CNC, that someone with a water-cooled graphite again even with saponification liquid will rust and easy cleaning
