Lapping and Polishing Basics - southbaytech.com

is when an abrasive particle in bonded to a substrate as with abrasive lapping films and SiC papers. Abrasive lapping films have various particles bonded to a thin, uniform polyester substrate and are also capable of producing a very flat surface. SiC papers are much thicker than the film and create the potential for rounded edges on the sample.
