For this reason the problem is commonly called ‘optical hazing’. Optical hazing occurs when polished or semi-polished tiles are factory processed, either by factory applied ‘nano’ sealers, or through the abrasive tile polishing process. It does not occur in matt tiles, or on any type of polished natural stone.

Grinding is the first step of mechanical material removal. Proper grinding removes damaged or deformed surface material, while limiting the amount of additional surface deformation. The goal is a plane surface with minimal damage that can easily be removed during polishing in …

Oct 31, 2008 Loose 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
