How to work?
The machine adopts C-type ND-D transformer single-phase reversible motor, to achieve short-circuit feed and automatically back action.ND-D single-phase reversible motor driven screw,make the electrode in drill move up and down with the feed nut.When it slowly decline, close to begin working ,remove waste with electromagnetic vibratorlitter , no damage to the workpiece, and increase the sensitivity of system as well
