本文提出了用于大口径长焦距物镜的定中心工艺方法与机床设备,它与常规的工艺方法不同,是利用一个精密空气轴承主轴作为磨边,胶合和装配的公共基准轴,由此可保证高精度大口径物镜(如航摄物镜,侦察卫星照相机镜头,气泡宣照相广角镜头等)最终装配后的定心精度要求。 This paper presents a centering process and machine tool for a large diameter long focal length objective which, unlike conventional process methods, utilizes a precision air bearing spindle as a common reference axis for edging, gluing and assembling, thereby ensuring High-precision large-aperture objective lens (such as aerial photography lens, reconnaissance satellite camera lens, bubble propaganda photo wide-angle lens, etc.) after the final assembly centering accuracy requirements.
