On the mechanism of material removal by fixed abrasive lapping of various glass substrates

Wear, 2013
Abstract Glass ceramics are one of the important materials for optoelectronic devices. Fixed abrasive, double-sided lapping parameters (time, pressure, and platen speed) were optimized using borofloat, BK7 and quartz substrates. Lapping of borofloat, BK7 and quartz substrates were performed at optimized conditions.
