In order to do the precision grinding of optical aspheric lens, it is essential to achievehigh quality surface roughness. Experiments show that the contacting area between the wheel andworkpiece in a grinding process is critical to influence the surface roughness for a fine grit sizeresin bonded wheel. The precision grinding are performed with BK7 optical lens. This paper dealswith the grinding of an aspheric surface optical lens by diamond wheel. This study also compareseach machining parameter (work spindle speed, wheel spindle speed, feedrate, etc.) in roughgrinding, fine grinding and polishing on the aspheric lens. In this study, several experiments werecarried out BK7 optical glass lens by using vitrified, metal, resin bond diamond wheel and thepolisher of urethane ball was used to remove the tool marks with an ultra-precision in-line grindingsystem. It was found that machining parameters significantly influence the surface roughness ofaspheric optical lens
