This application discloses a polishing device and its polishing process for an integrated steel wire production line, relating to the technical field of polishing and grinding equipment. It includes a preheating module, a primary coarse polishing unit, a low-temperature stress relief module, and a secondary fine polishing unit arranged sequentially along the steel wire's direction. The preheating module preheats the steel wire to 70-100°C. The primary coarse polishing unit uses multiple sets of grinding wheels for deep polishing. The low-temperature stress relief module heats the steel wire to 200-250°C to eliminate residual stress. The secondary fine polishing unit uses multiple sets of abrasive belt grinding components for fine polishing. This application achieves the technical effects of effectively removing deep defects on the surface of the steel wire, eliminating residual stress and bending deformation, eliminating coarse grinding marks, and correcting dimensional deviations.
