Large aperture ultra-precision mirrors are critical components in next-generation astronomical telescopes such as the China Space Station Telescope（CSST） and the MUltiplexed Survey Telescope（MUST）. However, traditional 5/6-axis CNC "Box machines" combined with sub-aperture polishing techniques (CCOS, MRF, IBF) face challenges in cost-effectiveness for large-scale production. This presentation introduces a robotic polishing system integrating Computer-Controlled Optical Surfacing (CCOS) and Magnetorheological Finishing (MRF), developed by Prof. Zhang Xuejun's team at Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP), to address these challenges.
