一、前言照相物镜、棱镜和滤光片等高精度光学零件在用古典法精磨或金刚石精磨片精磨后要进行抛光,抛光时要采用沥青、聚氨酯抛光模片等制作的抛光模并采用氧化铈、氧化锆等抛光粉。抛光工序是要去除前工序加工时所产生的变质层,并获得外观上没有缺陷、表面精度符合要求的光学表面。目前。使用金刚石精磨片的固着磨料精磨法正在逐步取代古典法精磨,而抛光工序也已开始试用固着磨料。
I. Introduction Photographic objectives, prisms and filters and other high-precision optical components in the classical method of fine grinding or diamond grinding after grinding to be polished, polished to be used pitch, polyurethane polishing die made of polishing and other modules Using ceria, zirconia and other polishing powder. Polishing process is to remove the metamorphic layer generated during the processing of the previous process, and obtain the optical surface without defects in appearance and with the surface precision meeting the requirements. Currently. The use of diamond grinding plate fixation abrasive refining method is gradually replacing the classical method of fine grinding, and the polishing process has also begun to try fixing abrasive.
