Abstract

The invention discloses a rapid machining process for a high-precision coaxial aspheric reflector with a lightweight structure, and belongs to the technical field of aspheric reflector machining. The process sequentially comprises the following steps: lightweight forming, milling and rough polishing, shaping and polishing, fairing processing, forming processing and fine trimming and polishing after forming. The machining mode of the center hole in the forming machining process is that after heating, a hot melting adhesive is used for adhering a machined part to the middle position of the end face of the window glass, a pressing plate is adopted for pressing the window glass for fixing, then the center hole is milled, and stress deformation can be effectively reduced. According to the machining method, the machining technological process of the coaxial aspheric reflector with the lightweight structure and the appearance forming requirement is provided, the machining period is short, the part precision is high, and wide application value is achieved.

Description

technical field [0001] The invention belongs to the technical field of aspheric mirror processing, and in particular relates to a rapid processing technology for a high-precision coaxial aspheric mirror with a lightweight structure. Background technique [0002] With the development of aviation technology, reconnaissance and early warning detection equipment has put forward higher and higher requirements for optical system performance, volume, and light weight. Aspheric mirrors have obvious advantages in correcting aberrations. Usually a single aspheric mirror can Realizing the effect of using multiple spherical mirrors can effectively reduce the complexity, size and weight of the optical system, so the high-precision coaxial aspheric mirror with lightweight structure has great application value. [0003] The existing processing technology has not been reasonably planned for the overall processing technology, and the control requirements of each link are not reasonable enoug...
