This work use the SPH method to study the relationship between grinding depth and grinding force of K9 glass in ultra-precision grinding, and the effect of grain shape on material removal. The …
Grinding the curve into the mirror face can be done by one of the following approaches: Ceramic tiled tool ground against the mirror face. Glass tool ground against the mirror face. Ring tool. Motorized grinding wheel on the end of along boom that is anchored that is moved back and forth across the mirror face.
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 …

Imagine a cutting tool that only cuts a hollow circle, kind of like a hole saw. When the tool is set at an angle other than the axis of the rotary table and the part is rotated under the tool, a spherical surface is …
IIRC one method used for generating spherical blanks from glass cubes was to grind/tumble them against abrasive bands on the periphery of a cylindrical container, compressed air was used to ensure tumbling. The SA from a ball lens is easily corrected with a suitable thickness plane parallel plate (ideally of the same glass) in the converging …
Grinding Glass from Rough Grind to Final Polish 5:21 MAKE YOUR BEST START If you've read through our Learn Section on the best disks to start with for your type of glass, you'll know that picking the right starting point with your diamond disk is as important a step as you can make.

If you look at my video above, standard lapidary equipment is used to make marble size spheres. The grind is inside a hollowed out SiC grinder wheel and the pre-polish is using granite pades cut to fit inside of appropriately sized pipe fittings. A friend at my class claims as many as 10 per hour can be made of 3/4" size agate cubes.

Use your ears to listen for a cutting or grinding sound between the cups and the sphere (note: you will not hear a cutting sound during the polishing stages). If you do not hear the cutting sound you may need to add more grit. Keeping a close eye and ear on the machine will result in a faster grind.
