A new manufacturing technology of radio telescope panel

Through a new manufacturing technology, achieved the machining of high precision composite radio panel. It adopts foil sticking in a vacuum, metal bonding, rubber precision compensation, stress release and other technology. Through designing the manufacturing process, and adopting a large number of experiment scheme to improve, finally summarized a technical route of high feasibility and accurate process parameters. At last, by the measurement of PGI Dimension red outside precision detector (the surface detection accuracy of which can reach 2 um) for surface precision of experimental panels, we verified the feasibility and reliability of this technique and provided the reliable data to support for practice application of this technology.
