The invention discloses a high-efficiency polishing equipment for hardware plate production, which comprises a bottom plate, a left side plate, a right side plate, a top plate, a workbench, a slider, a slide rail, a power mechanism, a second motor, a threaded rod, a support plate, a U Template, the third motor, polishing wheel, fixed rod and polishing agent extrusion nozzle, the present invention is provided with power mechanism, and power mechanism comprises the first motor, disc, connecting rod, sector gear and rack, through the above The components cooperate to realize the comprehensive polishing of the plate, and the polishing efficiency is high. It is equipped with a second motor, a threaded rod and a U-shaped plate. Through the cooperation of the above components, it can adapt to different thicknesses of metal plates, and can polish different plates. There is a polishing agent. Extrusion nozzle, while polishing, the polishing agent is extruded through the polishing agent extrusion nozzle at a uniform speed, which improves the work efficiency and at the same time, the polishing agent is extruded evenly and sufficiently, and the polishing effect is good.
