The invention provides a numerical control wire arranging device adaptable to occasions of drawing machines, enameling machines, tin machines, bare wire rewinder and the like and a wire arranging method thereof. The numerical control wire arranging device comprises a motor, a lead screw, a master screw, a forward rotating limit device, a counter-rotating limit device and an encoder, and thereby the numerical control wire arranging device has the advantages of simple structure, hard breakage and easy overhaul. In the wire arranging method, counting value of the encoder connected to the lead screw reflects angles of rotation and numbers of revolution of the lead screw, thereby reflecting straight-line motion distance of the master screw, and the encoder controls the motion of the motor through programs, thereby controlling range of motion and mode of motion of the master screw. Extreme position of the linear motion of the mater screw is limited by the forward rotating limit device and the counter-rotating limit device. After an input device of a control system is controlled to input set value, a combination of subprograms of system initiation, fixed distance wire arrangement, variable distance wire arrangement, variable speed wire arrangement and stop wire arrangement is operated for meeting requirements of wire arrangement of different take-up reels.
