| dc.description.abstract | The difference between optical glass and generally glass, Optical glass need fine nature and chemical property, Due to optical glass in the process of manufacture, Can be to make a lot flaw in surface, So Application to use as differentiate between the rank or worked it to recycle, As if try use freedom polish to assist mechanical polishing working, To proffer high hardness、low ductility and difficult to work the surface get a little remove and smooth effect on optical glass, To get up to need geometry shape.
About optical glass, abstruse grind polishing parameter effect work quality and efficiency, An arduous problem what was look for definition work parameter best, So the research use CNC tiny sculpture mechanical for work equipment, needle of sculpture mechanical change stainless steel abrasive stick Completely, It increase the polish pad or non-woven fabric on the bottom of the polish stick, Workpicec use 0.7mm Corning optical glass, The optical glass into the polish water of the CeO2 , The control parameters of the polishinf process include the polishing time, the axial loading, work time, polishing material, Moreover, the experimental parameters results were also analyzed and discussed .
The experimental parameters results, CeO2 particles of size 0.85–1.66μm (#8000) were used in this study, optical glass After turning machined surface polishing, Base on the different parameters experimental results, TZ-9000N and PQH5 polishing pad, On the suitable time, 15 min after the initial roughness of surface could be improved from 0.3 μm Ra (3.7 μm Rmax )to 0.03 μm Ra(0.25 μm Rmax ). The use Non-woven fabric polishing pad after polishing, On the suitable time, 15 min after the initial roughness of surface could be improved from 0.3 μm Ra (3.7 μm Rmax )to 0.04 μm Ra(0.3 μm Rmax ). | en_US |
