Abstract

In this paper, the authors present a new technique which through electrolytic truing, could use metal bonded supermicro diamond wheel to machine optical glasses and obtain optical surfaces with best-quality finish. Using this technique to machine K9, F4 and zerodur, the surface roughness Ra could reach a value less than 10 nanometer and a planeness less than 1 μm. In addition, the authors have also studied some phenomena occurred in the grinding process.
