Abstract

A cantilever wheel belt polishing device and polishing method with controllable pressure, which belong to the technical field of ultra-precision machining, and are mainly used to solve the problem that the polishing method in the prior art will introduce certain medium and high frequency errors during polishing, which will bring about the improvement of surface shape accuracy. It is difficult and cannot effectively polish complex surface optical components with large aspect ratio, especially the inner surface. At the same time, the controllable contact pressure polishing device mostly adopts a single contact control method, which cannot efficiently polish the optical components with a large difference from the target surface shape. The problem of the workpiece, the present invention includes a base plate, a wheel rod assembly, a driving assembly, a trimming assembly, a polishing belt, a tensioning assembly and a guide idler. The present invention is mainly used for ultra-precision machining of optically complex surfaces of hard and brittle materials.

Description

technical field [0001] The invention relates to a pressure-controllable cantilever wheel belt polishing device and a polishing method, belonging to the technical field of ultra-precision machining. Background technique [0002] In the complex surface processing technology in the field of precision optical processing, it is necessary to polish the optical surface after milling to reduce the damage of the workpiece and the surface roughness of the workpiece, and improve the surface accuracy and surface quality of the workpiece to meet the actual use. Require. At present, there are many methods for polishing curved optical components, such as magnetorheological polishing, water jet polishing, airbag polishing, ion beam polishing, laser polishing, etc. Most of the existing controllable contact pressure polishing tools are sub-aperture spherical polishing heads. It has good shape modification ability, but at the same time, it will introduce certain medium and high frequency erro...
