Problems solved by technology

[0003] The current traditional mirror surface processing equipment usually uses a single series mechanism to process the mirror surface. The series mechanism has the disadvantages of small rigidity, low precision, slow dynamic response speed, and large cumulative error.

The structure of this kind of mirror processing equipment is relatively complicated and difficult to control, and in the processing of large-scale curved optical mirrors with special purposes such as high-order curved surfaces, sinusoidal curved surfaces, and free-form surfaces, the number of repetitions of "surface shape measurement-polishing processing" increases. , there are problems such as low processing efficiency, damage to the optical mirror surface during processing, and affecting t
