Oct 12, 2020 Precision optical systems, such as lithographic projection lens or cameras for satellites, typically composed of glass or ceramics optical components. In the manufacturing processes of glass and ceramics components, grinding is a key technique for curvature generation (CG) of optical surface. However, dimension errors and sub-surface damage (SSD) of components occur during the CG process.

The machine grinds each lens to its proper shape and places a bevel around the edge of the lens so that the lens will fit the eyeglass frames. Water flows over the lens throughout this process. 10 If the lenses require additional grinding, the process is done by hand using a mounted power grinder.
