PURPOSE: A wire driving device is provided to efficiently remove scales formed with irregular height by vertically reciprocating a wire in addition to moving back and forth and rotation of the wire. CONSTITUTION: A wire driving device comprises a body, a rotating unit(120), a linear moving unit(130), and a control unit. The rotating unit is rotatably installed on the body. The rotating unit rotates a wire. The linear moving unit is installed on the rotating unit and rotates by the rotating unit. The linear moving unit moves the wire back or forth. The control unit drives the rotating unit and the linear moving unit. At least a pair of gears of the linear moving unit engage with each other and rotate. The wire moves through at least a pair of gears.
