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 Machining (AFM) excels where conventional polishing struggles—particularly for complex internal geometries and high-precision surfaces.Here’s how industries compare: 
Industries Best Suited for AFM  
1. Aerospace & Turbomachinery  
Polishes turbine blades,fuel nozzles,and cooling channels with tight tolerances (Ra < 0.2 µm).Outperforms manual methods in hard-to-reach areas (e.g.,S-shaped passages).  
2. Automotive (EVs & Fuel Systems)   

Ideal for fuel injectors,cylinder heads,and transmission components requiring deburring and uniform flow paths.More consistent than vibratory finishing for critical sealing surfaces.  
3. Medical & Implants  
Achieves biocompatible finishes on titanium implants (e.g.,spinal rods) without contamination risks from loose abrasives.Superior to electropolishing for complex porous structures (e.g.,3D-printed lattices).  
4. Energy (Hydraulics & Valves)  
Refines hydraulic manifolds and valve seats to reduce leakage and improve efficiency.Beats honing in cross-hole intersections and multi-port designs.Where Traditional Polishing Wins.Simple,external surfaces (e.g.,flat or cylindrical parts).High-volume,low-cost applications (e.g.,tumbling for fasteners).Conclusion:AFM dominates in precision internal finishing,while traditional methods suit high-throughput external work.
