Q873型小球面精磨机是最近经过鉴定并投入批量生产的光学零件精磨机。长期以来,光学零件的精磨加工,一直采用古典法或范成法进行的。不仅工效低、劳动强度大,而且精度也不稳定。新设计的Q873型小球面精磨机是采用准球心方法,对胶合在模具上的单个或成盘的球面光学玻璃进行精磨。磨料采用金刚石微粉丸片,不但可提高精磨工序的质量(光洁度达 Q873 spherical roller refiner is recently identified and put into mass production of optical parts refiner. For a long time, the optical components of the grinding process, has been using the classical method or fan into law. Not only low efficiency, labor-intensive, but also the accuracy is not stable. The new design of the Q873 spherical roller refiner is the use of quasi-ball-center method, glued to the mold on a single or into a plate of spherical optical glass for grinding. Abrasive using diamond powder pellets, not only can improve the quality of the grinding process (finish
