A Rapid Polishing and Polishing Method for Large-Aperture Optical Mirrors Based on Multiple Polishing and Polishing Systems

Abstract

The invention proposes a method for rapidly lapping and polishing a large-diameter optical mirror surface based on a multi-polishing system, which belongs to the field of optical element processing. It solves the problem that the existing large-diameter optical mirror has a long processing cycle and affects production efficiency. It includes multiple lapping and polishing systems. After mirror milling and molding processing and optical mirror positioning and fixing, multiple lapping and polishing systems perform surface rough grinding, surface fine grinding, surface shape training and polishing for multiple iterative processes until Complete surface processing. It is mainly used for rapid polishing of large-diameter optical mirrors.

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...

[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...
