Production Engineering Measures to Manufacture Super Fine Finish Beryllia.

摘要

The First Article units and a revised Test Report were submitted and accepted by the government. Pilot Run demonstration of the capability of progressive polishing to produce at least 1000 substrates per week of each of three sizes of super fine finish beryllia was completed using installed manufacturing-scale equipment. Working surfaces with 3 to 3.5 microinches surface finish resulted. The input substrates were commercially available 99.5% BeO parts of 1.0 inch by 1.0 inch or 2.0 inch by 2.0 inch dimensions.
