EDM machine hit a carbon, how to do?
EDM machine in the discharge process, when the gap between the electrode and the workpiece to a certain distance, the application of the electrode and the workpiece 0ntime will medium (spark oil) breakdown, the formation of discharge channels, also produced a spark began to discharge
At this time in the workpiece surface will leave a tiny pits, then discharge into thefftime period, discharge short stop, the electrode and the workpiece to restore the insulation state.
And exploded into the processing fluid, quickly solidified into discharge slag, the working fluid was taken away.
Discharge channel instantaneous concentration of a lot of heat, instantaneous temperature can be as high as 10,000 degrees Celsius, high temperature makes the workpiece surface melting, gasification.
