ELID grinding is a method that realizes high quality mirror surface grinding in the nanometer order by use of electrolytic dressing metal bonded wheels consisting of fine abrasives. Currently, ELID grinding is increasingly being applied as an ultraprecision grinding method to achieve desired surface roughness, high surface accuracy, high surface quality, and high grinding performance. This paper introduces the ELID grinding and discusses some applications of ELID grinding to mirror surface grinding. For ultraprecision optical components, ultra fine smooth surface quality of sub-nanometer or sub-angstrom in Ra may be required. To satisfy these requirements, ultraprecision on machine measurement system had been developed. Synergistic the nano precision mechanical method, nano precision measurement method with nano resolution machine, the ultraprecision components can successful to fabricate.
