Abrasive Flow Machining (AFM) is a non-traditional machining process used to polish, deburr, and improve the surface finish of complex internal and external geometries. It is particularly effective for hard-to-reach areas such as intricate passages, molds, and turbine blades.Process Mechanism:AFM involves forcing a semi-solid abrasive-laden media (composed of a polymer carrier and abrasive particles like silicon carbide or diamond) through the workpiece under controlled pressure. The media flows back and forth through the part, removing material through micro-cutting and erosion. The process can be performed using one-way, two-way, or orbital flow methods, depending on the application.  
Key Advantages:Precision Finishing – Capable of achieving surface finishes as fine as 0.05 µm Ra.Complex Geometries – Effective for intricate shapes, including cross-holes and irregular contours.No Thermal Damage – Unlike EDM or laser machining, AFM does not generate heat, preserving material integrity.Consistency & Automation – Suitable for high-volume production with repeatable results.Applications:Aerospace: Polishing fuel nozzles and turbine blades.Automotive: Finishing engine components and gears.Medical: Smoothing surgical implants and prosthetics.Mold & Die: Improving injection molds and extrusion dies.  
AFM is a versatile finishing process that enhances part performance by reducing friction, improving fatigue life, and ensuring tighter tolerances in critical applications.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!
