The Robot Polishing Machine is a high-precision automated system designed for polishing large-scale and complex optical surfaces. It integrates a 6-axis industrial robot platform (such as KUKA, ABB, or Stäubli) with advanced polishing modules and intelligent control software.
This system enables fully digital optical fabrication, covering the entire workflow from surface modeling and tool path generation to real-time force control and process monitoring. Compared with traditional manual polishing, it delivers higher consistency, improved efficiency, and superior surface accuracy.
