- W1992541261 abstract "Lightweight mirror is a key part in image-stabilized day/night optoelectronic observe/aim system. It is made of special structure titanium alloy base with sintered layer of optical glass. To meet with the requirement to reduce weight, honeycomb structure is adopted on the titanium alloy substrate. The depth of the optical glass is very thin. Due to its special & complex structure, high index requirement on image-stabilized technology, technology efficiency is very low with traditional polishing, and the quality is not stable. The loop polishing machine characterized with its stressless machining, is a kind of plain polishing machine tool, which has unique advantage in plain polishing machining of high accuracy large size and extra thin, changeable optical elements. We adopt loop-polishing technology in large area lightweight mirror machining. After parts fine grinding, first we adopt traditional polishing technique to conform pre-polishing for parts, then perform stressless polishing in loop polishing machine. Via tests and batch production, it solves the technical problems such as facial contour control and surface quality of the large area lightweight mirror; its working efficiency is 3-5 times than the traditional polishing technology." @default.
