3.Processing principle

 

The sinker EDM process uses an electrically charged electrode that is configured to a specific geometry to etch the shape of the electrode into a workpiece. Both of the electrode and workpiece submerged in an insulting liquid are connected to a source of current which is switched on and off automatically depending on the parameters set on the control panel. When the current is switched on, an electric tension is created between them. If the two parts are brought together to within a fraction of an inch, the electrical tension is discharged and a spark jumps across. Where it strikes, the material is heated up to melt. Innumerable such sparks spray, one after the other (never simultaneously) and gradually shape the desired form in the piece of metal, according to the shape of the electrode. Several hundred thousand sparks must fly per second before erosion takes place.
