Acidic magnetorheological finishing of infrared polycrystalline materials.

Chemical-vapor-deposited (CVD) ZnS is an example of a polycrystalline material that is difficult to polish smoothly via the magnetorheological finishing (MRF) technique. When MRF-polished, the internal infrastructure of the material tends to manifest on the surface as millimeter-sized "pebbles," and the surface roughness observed is considerably high. The fluid's parameters important to develop...

Effect of ZnO nano materials on grinding surface finishing

Surface roughness is a variable often used to describe the quality of ground surfaces as well as to evaluate the competitiveness of the overall grinding system. The subject of this paper is a grinding process performed on P20 tool steel by changing the grinding conditions, including the depth of cut, the grinding passes, the type of wheel, and the cutting fluid supply in the experiment. The mai...

Finishing of Optical Materials Using Fluid Jet Polishing

The characteristics of Fluid Jet Polishing (FJP), a newcomer in the field of optical fabrication, or more specifically optical finishing, are presented. Comments on the process possibilities are given, e.g. spot shape, process speed, and parameter dependencies. Preliminary results on a wide range of materials are discussed.

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...
