Bonnet Polishing is a method of modifying and polishing optical parts, which belongs to the field of mechanical engineering. It uses a spherical crown-shaped polishing head filled with air to form an airbag, and a special polishing film is pasted on it. Through the rotational movement of the airbag and the relative movement between the workpiece and the polishing film of the airbag, the abrasive particles in the polishing fluid remove the surface material of the workpiece in a precise manner and controllable, thereby realizing modification and polishing of complex materials. optical surfaces.
This technology was initially jointly developed by the optics laboratory of University College London and the British company Zeeko based on Computer Controlled Surface Shaping (CCOS) polishing technology. It solved key technical problems such as airbag development, polishing movement mode and equipment design. , and finally invented optical component airbag polishing technology.
Airbag polishing technology has a wide range of applications, especially in the processing of high-precision curved surface components, such as high-precision optical components. These components play a key role in the fields of aerospace and military defense, so it is crucial to develop it. its level of ultra-precise batch processing.
Due to the high cost of dedicated airbag polishing machines and the limited processing range of full-size airbag polishing machines, researchers developed a robotic airbag polishing system by combining airbag polishing technology airbags and robot-assisted treatment technology to reduce equipment costs and expand the scope of application.
In addition, the advantages of airbag polishing technology include uniform material removal, high polishing efficiency and good consistency. These advantages make it excellent in processing optical glass and other materials. For example, K9 optical glass was polished via an experimental annular airbag polishing platform. The study found that as the airbag pressure increases, the polishing efficiency of K9 optical glass increases, which shows that airbag polishing technology has a significant effect on improving quality of the surface. of materials.

The polishing tool used is a special flexible airbag. The shape of the airbag is a spherical crown, and a special polishing mold, such as polyurethane polishing pad, polishing cloth, etc., is attached to the outside. It is installed on the rotating work parts to form a closed cavity. The cavity is filled with low pressure gas and the gas pressure can be controlled. The polishing head itself rotates to create a polishing motion. The part can rotate and perform CNC link motion in the X, Y, and Z directions. When the part is a rotating surface, the part rotates and perform CNC link motion in the X and 2 directions; when the part is a free-form surface, the part does not rotate but performs CNC linkage movement in the X and Z directions.
