Description

technical field [0001] The invention relates to the field of ultra-precision machining, in particular to an efficient and high-quality ultra-precision polishing device for various curved surfaces such as planes, cylinders, aspheric surfaces, and special-shaped surfaces. Background technique [0002] As the most important process of ultra-precision machining of curved surfaces, polishing is mainly used to remove the surface damage layer produced in the previous processing process, correct the surface error, and reduce the surface roughness of the workpiece. Surface parts are widely used in astronomy, aerospace, navigation, auto parts, molds and other fields. For example, the use of aspheric optical parts in the field of astronomical observation can improve the identification ability of observation equipment and simplify the structure of equipment; a large number of mold cavities and auto parts use complex free-form surfaces. The processing quality of complex curved surfaces ...
