Abrasive Flow Machining (AFM) relies on several key components working together to achieve precision finishing. The main elements include:  
1. Abrasive-Laden Media: A viscoelastic polymer carrier (typically silicone-based) mixed with abrasive particles (e.g., silicon carbide, diamond, or aluminum oxide).  
The media’s viscosity and flow properties determine material removal efficiency and surface finish quality.Abrasive concentration (10%–60%) and grit size (50–800 mesh) are adjusted based on the required finish.  
2. Workpiece Fixturing: The workpiece must be securely clamped between two media cylinders to ensure uniform abrasive flow.Custom tooling and fixtures guide the media through complex internal passages or external contours.  
3. Hydraulic or Pneumatic Drive System:Hydraulic piston forces the abrasive media through the workpiece under controlled pressure (1–15 MPa).Some systems use reciprocating flow (back-and-forth motion) for better finishing uniformity.  
4. Machine Tool Structure:Rigid frame supports high-pressure media flow without deflection.Programmable controls adjust extrusion pressure, flow rate, and cycle time for repeatability.  
5. Filtration & Media Conditioning System:Filters remove debris and worn abrasives to maintain media consistency.Cooling systems may prevent overheating during prolonged machining.Conclusion:AFM's effectiveness depends on the synergy between abrasive media, fixturing, drive systems, and machine rigidity.Proper selection of these elements ensures optimal deburring, edge radiusing, and surface finishing in complex geometries.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!
