Enhancing the Performance of Gears with Isotropic

Isotropic superfinishing is a process that is capable of producing a low surface roughness (typically less than 4 µin/0.1 µm), non-directional micro-texture. It is this low surface roughness micro-texture that separates isotropic superfinishing from grinding or machining processes as well as from mirror-polishing (non-textured) processes.

Lapping process Lapping is basically an abrasive process in which two surfaces are rubbed together with an abrasive between them, by hand movement or by way of a machine. Lapping is a loose abrasive bonded process. Because loose abrasive particle is used instead of bonded abrasive particles Material removal in lapping usually ranges from .003 to .03 mm but many reach 0.08 to 0.1mm in certain cases

Superfinishing - Wikipedia

Superfinishing, also known as micromachining, microfinishing, and short-stroke honing, is a metalworking process that improves surface finish and workpiece geometry. This is achieved by removing just the thin amorphous surface layer left by the last process with an abrasive stone or tape; this layer is usually about 1 μm in magnitude.
