Renewable polishing lap

摘要

A polishing lap which is resistant to attack from corrosive and reactive polishing media and which has a surface which is sufficiently resilient to provide good finishes without hindering dimensional controlling and accuracy of the texturing comprises: a lap substrate wherein the surface of the lap substrate has an overall shape and a localized texture; and a replaceable lap film applied to the lap substrate surface and which is deformed to correspond to the localized texture of the lap substrate surface. The polishing lap can be easily reconditioned if contaminated or easily modified for use with different abrasives and polishing media.
