The invention discloses a wire cutting machine. The wire cutting machine comprises a rack, a wire fixing mechanism, a rotary cutting mechanism and an electrical control device, wherein the wire fixing mechanism is fixed to the rack, and the rotary cutting mechanism rotates around the central axis of the wire fixing mechanism. The rotary cutting mechanism comprises a cutting motor rotating around the central axis of the wire fixing mechanism, a cutting disk fixed to a driving shaft of the cutting motor, a rotating mechanism used for driving the cutting motor to rotate, and a stepping motor adjusting mechanism used for driving the cutting motor to move towards the center of a wire. The rotating mechanism is arranged on the rack, and the cutting motor and the stepping motor adjusting mechanism are arranged on the rotating mechanism. According to the wire cutting machine, the cutting motor rotates around the wire so that an aluminum strand in the wire can be cut, and the advantages of being high in cutting speed, good in cutting quality and neat in appearance are achieved; a pressing pipe can be penetrated in for pressing easily, cutting time is shortened to be about 15 seconds from 5-6 minutes in manual cutting, a stepping motor is used for controlling the cutting depth, control precision is high, and the wire cutting machine is suitable for wires of various specifications.
