PURPOSE: An object machining device and a method thereof are provided to remove noise by avoiding the collision of arc and the air because the air is not jetted while the arc is generated and the air is jetted while the arc stops generating. CONSTITUTION: An object machining device comprises a current supplying unit, an air jetting unit, and a control unit. The current supplying unit generates arc between objects and electrodes. The air jetting unit jets air from the electrodes to the objects. The control unit controls a current supplying device and an air supplying device to alternatively implement generating arc and jetting the air. |
