An Introduction to the Optics Manufacturing Process

Oct 31, 2008Loose abrasive grinding uses inverse spheres of the same radii ground together so that the hills and valleys on the optics will wear away to produce a true sphere. Slurry flows in between the blocked parts and the spherical tool to keep the parts cool and wash away debris created during the grinding process. Polishing

Centerless Grinding

Centerless grinding is similar to centered grinding except that there is no spindle. This allows high throughput since parts can be quickly inserted and removed from the process. There are three main types of centerless grinding: Throughfeed grinding. Infeed grinding. Endfeed grinding. ThroughFeed Grinding.
