Fining/Polishing

Fining, or polishing, is needed to obtain a perfectly smooth surface on both sides of the lens, and involves the use of a polishing slurry and polishing pads. Cerium oxide slurries are used exclusively on glass, while harder aluminum oxide slurries are used on plastic.  In either case, a free-flowing, non-packing slurry is essential for optimum, consistent removal rates. Intersurface Dynamics’ additives, for both aluminum oxide or cerium oxide abrasive, are formulated to increase slurry stability, prevent tank packing and maximize results in high production environments.
