What is Spherical Lapping and Polishing?

Most micro-scratches produced with small micron aluminum oxide abrasive will be less than .000001” (.025 micron) deep and can’t usually be measured with a profilometer. Micro-scratches should not be confused with deeper scratches produced by particles of contamination or other causes. Spherical Lapping vs "Flat" Lapping
