Six-Axis Airbag Optical Polishing Machine

Airbag optical polisher, with full 6-axis coordinated motion, supports polishing of spherical, aspherical, and off-axis aspherical surfaces, offering flexible tool-path control for complex geometries. The air-bag polishing head provides adaptive, uniform pressure distribution, ensuring stable material removal and high surface quality. The system is compatible with a wide range of optical materials, including optical glass, single-crystal silicon, sapphire, SiC, metals, and ceramics. Its multi-surface capability and broad material adaptability make it suitable for high-precision optics manufacturing in imaging, aerospace, and semiconductor applications.

4. PDAU CAM Software

The PDAU CAM software supports various function inputs for surface removal and advanced cleaning, while also enabling light curves, spiral trajectories, and multiple steps for curved surface generation. Learn More

5. Non-Orthogonal Rotary Swinging and Precession Motion

The unique non-orthogonal rotary swinging arm and precession motion mode prevents the polishing speed at the center of the contact zone from dropping to zero, avoiding the “M-shaped” removal function. It produces non-periodic surface textures and achieves better surface quality, while enabling a quasi-Gaussian removal function that promotes faster form convergence.

6. Air Bearing Spindle (Optional)

The air bearing grinding spindle uses dry, clean air through microporous layers to support the rotor shaft against the stator, enabling fast, smooth rotation without contact, ensuring exceptional accuracy and stability. Learn More

7. Adjustable-Pressure Airbag

The adjustable-pressure air-bag polishing head ensures excellent conformity to the workpiece surface. Combined with advanced CAM algorithms, it effectively improves polishing efficiency and surface quality.
