In the aerospace field, the pursuit of ultimate component reliability has never ceased. Among these, the internal surface quality of components directly impacts fuel efficiency and safety. Today, abrasive flow polishing machines are becoming the unsung heroes ensuring these critical quality aspects.
Unlike traditional polishing methods relying on manual labor or rigid tools, abrasive flow polishing machines operate on a unique principle. They utilize a special polymer medium mixed with fine abrasive particles, which, under controlled pressure, is forced through the internal channels of the workpiece. During this flow, the abrasive continuously and uniformly micro-cuts micro-burrs and irregular surfaces. The entire process is precisely controlled by the equipment to ensure consistent material removal, ensuring no impact on the original precision of the workpiece.
This technology is widely used in the final finishing of turbine blade cooling holes, fuel system components, and hydraulic valve bodies. It not only removes micro-burrs that can lead to stress concentration but also achieves a mirror-like flow channel surface, significantly reducing fluid resistance and the risk of carbon buildup, providing crucial technical support for improving engine efficiency and flight safety.

Abrasive Flow Machine Uses Diamond Fine Powder,Silicon Carbide Powder or other Abrasives Mixed Into Polymer Elastic as a soft medium.The abrasives flow up and down through the inner holesor over the machined surface to achieve surface polishing.Especially suitable for all kinds of mould and irregular shape tiny cavities.
Abrasive flow is not only a device,but also a system engineering!It includes equipment,abrasives,tooling fixtures,and important detail design and experience,which are not only reflected in the final effect and efficiency,but also reflected in the long-term stable use,and can help customers save a lot of trial and error costs!
