The greater contraction of the inner layer during manufacturing induces compressive stresses in the surface of the glass balanced by tensile stresses in the body of the glass. For glass to be considered tempered, this compressive stress on the surface of the glass should be a minimum of 69 megapascals (10,000 psi). ... Any cutting or grinding ...

The strings stick firmly to the glass as you pull the tape loose. It took my twice as long to get the strings off the glass using a razor blade than it took to assemble the grinder. (Actually the tape wasn''t actually holding the glass to the package in the first place.) I''d think masking tape or duct tape would do as well and be easier to remove.

glass. In short it is an extension of grinding. This is also called the ''hypothesis of abrasion''. The other theory is ''flow theory'' or ''flow hypothesis'', which says that the polishing compounds can be used to form amorphous layer of glass that can be smeared to fill the voids of the glass surface was proposed by Beilby . Finally ...
blank. A lens is typically ordered from a glass company in a form called a glass blank. From there, the lens goes through generation where the rough shape is ground into the blank. A lens is then blocked and undergoes further grinding to improve the surface and shape. Polishing is the final fine grinding stage where the surface and shape of the ...
Optical fabrication and testing spans an enormous range of manufacturing procedures and optical test configurations.. The manufacture of a conventional spherical lens typically begins with the generation of the optic''s rough shape by grinding a glass blank. This can be done, for example, with ring tools. Next, the lens surface is polished to its final form.
