Ultra-precision milling and grinding for large-sagittal MgF2 aspheric optical elements

Qiancai Wei,
Pengli Lei,
Fei Fan
et al.

Abstract: Ultra-precision machining for large-sagittal aspheric optical elements has become one of the research hotspots in the world's processing and manufacturing field in recent years. This paper mainly studies the processing of large-sagittal MgF2 aspheric optical components,analyzes the grinding tracks of two different grinding methods, and seeks the best grinding method. Experimental research was carried out on three milling modes in the rigid grinding process. In the processing method of pressed milling, the rota… Show more
