Embodiment Construction

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0037] In order to achieve fast and high-precision large-caliber optical processing, in the time-consuming polishing process, the traditional single polishing system processing is changed, and multiple polishing system combinations are adopted, and multiple polishing systems are realized through numerical control systems and intelligent synchronous control methods. The system works in an orderly manner at the same time, solving the problem of low polishing efficiency, greatly improving production efficiency and reducing costs.

[0038]Based on the state of the high, medium and low frequency bands of the mirror surface, different sizes and characteristics of polishing tools can be used. Such as metal grinding discs, airbag heads, magnetorheological, asphalt discs, etc., to achiev...

Abstract

The invention provides a large-aperture optical mirror surface rapid polishing method based on multiple polishing systems, and belongs to the field of optical element processing. The problems that an existing large-diameter optical mirror face is long in processing period, and the production efficiency is affected are solved. A plurality of polishing systems are included, after mirror surface milling and grinding forming treatment and optical mirror positioning and fixing are carried out, and surface shape rough grinding, surface shape fine grinding, surface shape grinding and repairing and polishing are carried out through the multiple polishing systems till surface shape processing is completed. The large-aperture optical mirror surface rapid polishing method based on the multiple polishing systems is mainly used for quick polishing of large-aperture optical mirror surfaces.

Description

technical field [0001] The invention belongs to the field of optical element processing, in particular to a method for rapidly lapping and polishing large-diameter optical mirrors based on a multi-polishing system. Background technique [0002] In the design of modern optical imaging systems, aspherical reflective optical systems are widely used. This system has obvious advantages in its simple structure and strong imaging resolution. In the process of traditional optical system design, production and integration debugging, the processing of optical components is the link with the longest period, especially for medium and large-scale optical mirrors with a diameter of 500mm or more. [0003] In the processing stage of optical components, the main process sections include mirror milling and molding, mirror grinding and polishing, and mirror finishing. In the process of mirror grinding and polishing, the surface shape of optical components, such as surface error, waviness and...
