应用德国LOH公司生产的SPM-60数控铣磨机和SPS-60数控抛光机, 开展了对小曲率透镜高效加工工艺的研究。通过利用正交试验, 确定了抛光中对元件面形影响显著的因素, 并利用单因素实验确定了最佳的工艺参数, 其中抛光模转速700 r/min, 抛光模压力0.16 bar, 抛光时间500 s, 结合元件在铣磨、精磨后的面形, 统筹安排零件的加工次序, 最终实现小曲率透镜的高效加工工艺。

The high efficient fabrication craft research on the low curvature lens has been done through the numerical control milling and grinding machine SPM-60 and the numerical control polishing machine SPS-60 made by LOH company in Germany. The obvious craft factors influencing on component surface during polishing process have been found through the orthorhombic experiment. The best craft parameters have been found by single factor experiment, such as 700 r/min rotatory speed of polishing tool, 0.16 bar pressure and 500 s polishing time. Depending on the surface shape of the lens after milling and grinding and fine grinding, the proper polishing order is done to realize the high efficient process craft of the low curvature lens.
