conditions should follow that wire cut EDM work correctly

The gap between electrode wire and workpiece should be certainly maintained in a required range. Within this range, not only impulse power can break through insulating liquid to create spark discharging, but also the eroded workpiece can be flushed away after discharging process. If gap is too big, insulating liquid can’t be break through,, and there will be no spark discharging; if gap is too small, short circuit is easy to happen, no spark discharging neither.

The procedure should happen in the liquid with insulate capacity, for example saponification and deionized water, the liquid could act as medium of discharging channel and provide cooling and flushing.

Electrical discharging should be short time impulse discharging,. As with short discharging time, the released heat won’t affect inside material of workpiece, and limits energy to a tiny field and keep characteristics of cool machining of wire cut EDM machine.  EDM Filters
