Basics of Mirror Grinding - Brown University

2009-2-2 · Basics of Mirror Grinding. Glass mirrors are typically ground from a blank, or cylindrical piece of glass, using the abrasion created by moving the mirror across a second glass blank (the tool) which is covered with silicon carbide or aluminum oxide grits. The initial rough grinding process uses grit sizes of 60, 120, and 180 to carve out the ...

Study on a 5-axis precision and mirror grinding of glass ...

The precision freeform grinding depends on the on-machine truing of diamond wheel, leading to the inefficiency of grinding system. Hence, a virtual ball-end algorithm along with a fixed tool posture angle is proposed for the 5-axis grinding of glass by using a self-dressing diamond wheel.

2021-5-31 · It is not a robot, but just a pattern of polishing. For big aperture though, spinning a large mirror and moving a large polisher might be too much work. That is why the mirror lab spun caste their glass to avoid hogging, and then had a robot go around grinding and polishing the high spots. Or maybe they spun ground it.

We recommend Pyrex over plate glass simply because it is much easier to build your first mirror with pyrex. The low coefficient of expansion of Pyrex makes a difference during the grinding process. Plate Glass, particularly thin blanks, can be warped by the warmth of your hand, expandings the glass into the tool, and grinds unevenly.
