Deburring: What Is It? How Does It Work? Types & Processes

Micro-abrasive blasting is more precise in creating smoother surfaces without damaging or changing the dimensional accuracy of the part. This process uses very fine abrasive media such as aluminum oxide, glass beads, and plastic media and a miniature nozzle to produce a controllable abrasive jet that can target and remove microns of material.

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. Superfinishing, unlike polishing which produces a …
