grating force-controlled CNC polishing system
This equipment uses an industrial-grade six-axis robotic arm as the motion execution unit, equipped with a high-response force-control polishing module and a digital process control system, forming an intelligent optical element processing platform. The robotic arm positioning accuracy reaches ±0.02mm, with repeat positioning accuracy better than ±0.01mm, combined with a 0.1N-class closed-loop force control system to ensure dynamic stability during processing.
