Abrasive flow polishing (AFP) is a highly effective method for refining intricate internal surfaces that are difficult to access with traditional polishing techniques.The process relies on a semi-solid abrasive medium—typically a polymer-based carrier mixed with fine abrasive particles—which is hydraulically forced through complex passages under controlled pressure.As the abrasive medium flows through internal cavities,it conforms to the contours of the workpiece,uniformly removing microscopic peaks,burrs,and surface irregularities.
The key to its precision lies in the adjustable viscosity of the medium and the bidirectional flow motion,ensuring consistent material removal even in hard-to-reach areas like fuel injector nozzles,cooling channels,and medical implants.Unlike mechanical polishing,which can leave tool marks or uneven finishes,AFP produces a smooth,isotropic surface without altering part dimensions.Advanced process controls allow manufacturers to fine-tune parameters such as flow speed,pressure,and abrasive concentration to achieve the desired surface finish—from rough deburring to mirror-like polishing.This makes AFP indispensable in industries requiring ultra-precise internal finishes,such as aerospace,automotive,and medical device manufacturing.
