An Introduction to the Optics Manufacturing Process

Oct 31, 2008 · grinding process. As the polishing process continues, the pitch will slowly conform to the shape of the optic so that the surface of the optic is smoothed out, but its overall radius is not changed. To aid in removing debris, grooves are cut along the pitch to allow slurry to flow more readily between the tool and the optic.

What is Single & Double Side Fine Grinding?

Fine Grinding (flat parts - single or double-side) is the abrasive machining process for removing material using a bonded Superabrasive wheel at low speed with a liquid to keep the part cool. The fixed grain of a geometrically indefinable cutting shape acts like a plow (fig. 3) and material is removed by micro-grooving /-cutting (fig. 4).

ID and OD Shoe Grinding for Thin-Walled Workpieces

Shoe grinding process for thin-walled workpieces. Shoe grinding is a variation of centerless grinding. Using a magnetic plate to support the wokpiece axially while driving the blank along with a set of precision rollers (shoes) that support the wokpiece radially, shoe grinding enables both ID and OD surfaces to be ground in a single setup.
