Paper Abstract

Gluing technology has been widely used in aerospace, optical, electrical and mechanical and other related industries, and already has excellent bonding strength, mechanical properties and airtightness, gluing material selection and process which is a key issue. In this paper, we choice EC2216 glue to assemble a reflective telescope primary mirror. In this study, a lightweight aluminum mirror with a diameter of 566 mm with three stainless parts have been taken as the gluing and assembly benchmark. We control the thickness of the glue between 0.35 ± 0.15 mm by a 0.3 mm shim, and control stainless parts on the Neutral plane effectively at the same time, after the installation of bipod in the future, this assembly can ensure effective verification to avoid stress is transmitted to the mirror distortion caused by the optical system. This paper aims to provide assembly and aligning by coordinate measurement machine (CMM). In order to obtain more accurate optimization results, we trace parts and the measurement results of CMM.
