A Better Way to Dress Bonded Diamond Grinding Wheels Bonded diamond grinding wheels occasionally need to be trued and dressed. This may be a result of normal tool wear, or excessive grinding loads if not using optimal processing parameters (i.e. – tools speeds, and feed rates).
Diamond Crystal: A gem-quality diamond crystal in the rock in which it was formed. It is an octahedral crystal with triangular dissolution features on its surface and an estimated weight of about 1.5 carats. From the Udachnaya Mine, Yakutia, Siberia, Russia.
Optical manufacturing 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.

Oct 31, 2008· Before the lens undergoes further grinding, the lens must be blocked, or mounted, to begin the process. Blocking involves mounting lenses onto a convex or concave surface (inverse of the tool being used) with pitch or wax. A lens can be blocked individually (Figure 3a), but more often, many lenses with the same radii are mounted on one surface
