The emergence of new energy vehicles and energy storage industries has led to a surge in demand for aluminum alloy components such as battery tray and inverter housing shells. The need for polishing weld seams and removing mold lines has increased dramatically. Automated polishing and retrofitting are urgently required. Beijing Stier CNC, a manufacturer of automated polishing robots, has secured numerous orders from leading new energy companies thanks to its self-developed floating polishing heads.
New energy aluminum casings are mostly thin-walled sheet metal components with wall thicknesses less than 2 mm. Due to their low rigidity, they are prone to deformation and can easily become unusable. The Steil floating polishing head has a minimum soft force output of 4N. The floating travel compensates for welding deformation errors, preventing damage to the workpiece and deformation. The equipment supports Modbus communication, allowing seamless integration with various domestic and imported robot control systems. Small and medium-sized manufacturers do not need to replace their existing robotic arms; they can simply add polishing heads to achieve automation.
The implementation cases of multiple new energy supply factories in Jiangsu and Shandong provinces demonstrate that after adopting the Stier robot’s automated polishing solution, the polishing time for individual aluminum shell weld seams was reduced from 12 minutes to 3 minutes, and the scrap rate decreased from 11% to 0.8%. The workshop has finally bid farewell to the harsh manual polishing workstations plagued by dust. As a local manufacturer deeply involved in polishing processes, Beijing Stier CNC can provide on-site measurement and customization of polishing processes, offering a one-stop solution featuring robots and floating polishing heads.
