Loose abrasive grinding uses inverse spheres of the same radii ground together so that the hills and valleys on the optics will wear away to produce a true sphere. Slurry flows in between the blocked parts and the spherical tool to keep the parts cool and wash away debris created during the grinding process. Polishing

Generally rough sphere-shaped work pieces made of fragile material are ground into more uniform spheres. The rough spheres are fed into a holding plate having a channel cut into the bottom side of the plate with a width slightly larger than the largest diameter of the rough spheres. A movable abrasive surface is positioned adjacent to the bottom side of the holding plate.

You can search "generating a sphere" here on PM using the search tool. Here is a link to an article that describes the process in pretty simple terms. Rather than a flycutter on a boring head used to machine the part, you would mount a diamond dresser point in a boring head at a given radius and angle and use that to dress your grinding wheel.
