Fixed abrasive diamond fine grinding pads for enhanced processing of optical glasses
On demand | Presented live 21 October 2021
We investigate the use of an innovative fixed abrasive diamond fine grinding pad, Squadro-G, for the fine grinding of various glass types. Through continuous development of the diamond abrasive matrix, grain size and concentration, we have found significant pathways to improve the process performance of the fine grinding operation. For the various glass types used in the investigation the process performance was monitored based on materials removal rates, surface quality, run-to-run consistency and Squadro-G pad lifetime. Data shows the use of Squadro-G fixed abrasive grinding pads can enable efficient processing of various types of glass and tool configurations. Ultimate flexibility is gained via the availability of different grit sizes, dedicated pad configurations with respect to given glass types, and east mounting and dismounting.
