Ultra-precision Float Polishing of Optical Materials

Recent Advances in Polishing of Advanced Materials

This article discusses the recent advances in polishing of advanced materials. Ninety-five journal articles published in 2005–2007 are briefly introduced. The topics are advances in chemical mechanical polishing (CMP), fluids for polishing, modeling of polishing, polishing of brittle materials, robotic polishing, polishing with vibrations or beams, and friction in polishing processes. CMP is pe...

Surface characteristics of resin composite materials after finishing and polishing.

This in vitro study determined the surface roughness (Ra) and absolute gloss (AG) values for 2 resin composites: a microhybrid and a microfill. Eight groups (n = 4) of each resin composite were prepared, along with 4 controls (Mylar strip) for the 2 resin composites. After finishing with a medium polishing disc, the specimens from each resin composite material were subjected to 7 polishing proc...

Roughness Analysis on Composite Materials (Microfilled, Nanofilled and Silorane) After Different Finishing and Polishing Procedures.

The finishing and polishing of composite materials affect the restoration lifespan. The market shows a variety of finishing and polishing procedures and the choice among them is conditioned by different factors such as the resulting surface roughness. In the present study, 156 samples were realized with three composite materials, -microfilled, nanofilled and silorane-, and treated with differen...

Material removal in the optical polishing of hydrophilic polymer materials

The optical polishing of hydrophilic polymer materials is a complex process that requires a comprehensive setting of various operating parameters. Based on a series of experimental investigations and dimensional analysis, this paper presents a simple empirical equation to evaluate material removal in the polishing of optical spherical surfaces of hydrophilic polymer materials. It is shown that ...
