Ultra Precision Surface Grinding for Large Scale Non-Axisymmetric Aspheric Lens

Abstract:

Ultra precision grinding is currently the main technology for large scale advanced optical lens machining. In this paper, the machining system of ultra precision surface grinder is investigated. The experiments of new wedged aspheric lens with the dimension of 430*430mm have been conducted by SD600 diamond wheel, and the parallel grinding, cup truing and on-machine measuring are used for good accuracy. The results show the effective machining system and the problem for next research.
