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.
