Development of ultra–precision machine for small–size lens mold machining

Abstract

The ultra–precision machine for small–size lens mold machining has been developed. The developed machine uses linear guider as axel bearing, and is consisted of ultra–precision on machine measuring (OMM) system and ultra–precision CAM system. It combines ultra–precision diamond turning, grinding and on machine measuring functions in one machine in order to realize high–efficiency and ultra–precision machining of lens mold by using compensation function based on OMM result. According to experimental statistics, the ultra–precision and high–efficiency machining of small–size lens mold can be achieved by using this machine.
