前言目前,铣磨、高速精磨和高速抛光是光学工艺研究的主要课题。为了获得更理想的经济效果和生产效率,使之适合于各种批量生产的范成法精磨、抛光工艺也正在摸索。范成法与准球心法相比之下,范成法具有很多优点。例如,用一种标准磨轮,可加工多种曲率的透镜,不需要制模与修模,加工精度主要由机床来控制,因此,工艺方法简单,对工人技术等级要求也不高,容易实现自动化。范成法精磨抛光可实现 Foreword At present, milling, high speed grinding and high speed polishing are the main topics of optical technology research. In order to obtain a more satisfactory economic results and production efficiency, making it suitable for a variety of mass production Fan Cheng law grinding, polishing process is also explored. Fan into law and quasi-ball heart law compared to Fan Chengfa has many advantages. For example, using a standard grinding wheel can process lenses of various curvatures without the need for mold making and mold repairing. The machining accuracy is mainly controlled by the machine tool. Therefore, the process is simple and requires no technical level to workers and is easy to automate . Fan Cheng polishing can be achieved
