| (1) Wire EDM – short for CNC wire EDM. (2) Working principle: It uses a moving metal wire as a tool electrode and passes a pulse current between the metal wire and the workpiece. It uses the corrosion effect of the pulse discharge to cut the workpiece. (3) Since it uses a wire electrode, it can only perform contour cutting. (4) Working principle. 1–CNC device 2–Wire storage tube 3–Guide wheel 4–Electrode wire 5–Workpiece 6–Nozzle 7–Insulating plate 8–Pulse generator 9–Hydraulic pump 10–Water tank 11–Control stepper motor (5) When the gap between the workpiece and the wire electrode is sufficient to be broken down by the pulse voltage, a spark discharge is generated between the two to cut the workpiece. (6) By issuing the command of the CNC device 1, the stepper motor 11 is controlled to drive the X and Y plates to move, and workpieces with arbitrary curve contours can be processed. |
