随着我国电视工业的迅速发展,工业电视的应用越来越广泛。光学电视磨边定中心仪是工业电视应用于光学冷加工的具体实例。磨边定中心为什么要采用工业电视?它的优点是什么?这得从传统的磨边定中心方法谈起。一、传统磨边定中心方法的精度及其弊病在光学冷加工中,透镜磨边定中心的传统方法是将被定心透镜用松香粘在定中心磨边机主轴的夹头上,旋转被定心透镜,用肉眼观看远处灯泡两个反射灯丝象的跳动量,直到灯丝象不再跳动就说明透镜前后两面的曲率中心都落在机床主轴的轴线上,即透镜已定好中心,然后引进砂轮进行磨边。如果磨边机主轴没有
With the rapid development of television industry in our country, the application of industrial television is more and more widely. Optical TV edging centering instrument is used in industrial television optical cold processing of specific examples. Why does the edging center adopt the industrial television? What is its merits? This has to be discussed from the traditional edging centering method. First, the traditional method of centering edging accuracy and its drawbacks In optical cold processing, the traditional method of lens edging centering will be centering lens with rosin stick in the central edging machine spindle chuck, the rotation is set Heart lens, with the naked eye to see the distance between the lamp bulb two reflex filaments beating, until the filament is no longer beating the lens on both sides of the front and rear center of curvature of the axis of the spindle, that is, the lens has been set good center, and then the introduction of grinding wheel Milling. If the milling machine spindle is not
