The multi-wire cutting equipment is efficient and accurate squaring equipment, is high in technical level and can perform multi-block squaring of materials at a time. The working principle is that a wire net which reciprocates at a high speed is formed on a roller by a cutting wire to efficiently cut a workpiece to be cut entering a cutting area, a V-shaped groove with a certain depth is carved on the roller, and the cutting wire forms the wire net by winding the groove of the roller. Since the multi-wire cutting apparatus has advantages of high precision, high efficiency, low power consumption, etc., it is gradually replacing the conventional cutting method. However, in the roller grooving process required by the cutting equipment, because the positioning reference of turning required in grooving is not consistent with the roller design reference and the positioning reference of turning is not consistent with the phi 20 positioning reference, after the roller is grooved, when the roller is installed on the multi-line cutting equipment, the grooved groove may not be on the same plane, so that a certain angle of a cutting line can be formed in the winding process, a certain error is generated in the material cutting process, and a product after cutting is not in accordance with the specified requirements, thereby causing waste of raw materials and improving the production cost.
