The equipment utilizes a 180° rotary indexing table, and the rear axle suspension can be loaded and unloaded via a robot or manually using a power-assisted manipulator. Shot peening occurs simultaneously with loading and unloading for high efficiency and convenience. Equipped with a G80II shot peening system, the machine features 2 spray nozzles driven by a FANUC 6-axis robot. A workpiece rotation mechanism mounted on the turnover door coordinates with the robot to precisely strengthen weld seams, achieving a cycle time of 90 seconds per part.
