We perform micromachining or superfinishing on work pieces for enhanced appearance and lifespan, the result is a cross-hatched surface with less than 2 RA rather than a glossy surface.  Superfinishing is the rotation of an abrasive stone or tape in one direction over a machine component spun in the opposite direction to produce a relatively smooth surface free of the amorphous layer left from grinding. Superfinishing is also known as micromachining, micro finishing and short-stroke honing.
