, Imposed on the electrode and the workpiece 0ntime will medium (spark oil) breakdown, the formation of the discharge channel, also produced a spark began to discharge. X0d discharge channel instantaneous concentration of a lot of heat, instantaneous temperature can be as high as 10,000 degrees Celsius,
Then discharge into the offftime period, discharge short stop, the electrode and the workpiece to restore the insulation state. X0d
High temperature makes the surface of the workpiece melting, gasification and explosive splashing into the processing fluid, quickly solidified into discharge slag, the working fluid was taken away. X0d At this time on the surface of the workpiece will leave a tiny pits,
Why does the EDM machine accumulate carbon? Carbon: EDM Discharging is not normal. X0d EDM In the discharge process, when the gap between the electrode and the workpiece is reduced to a certain distance
