Grinding of aspherical SiC mirrors - ScienceDirect

01-01-1996  This paper describes the methods using bonded cup wheels for grinding toroidal and cylindrical SiC mirrors with large curvature radii. Since the angle between the cutting direction of bonded abrasives and feed direction of the cup wheel is about 90°, it is possible to obtain a surface with very low surface roughness independent of the direction of measurement.

Mirror grinding Hacker News

By carefully doing a uniform rotation of the pieces during grinding, the resulting shape is symmetrical - spherical or flat. Other shapes are also used in mirrors (revolution surfaces generated by a parabola, hyperbola or ellipse), but they are all basically just small corrections to a sphere (which is a revolution surface generated by a circle).
