Using abrasive flow machining, Extrude Hone AFM can reach difficult internal geometry with flexible abrasive media, removing recast and improving the surface without relying entirely on direct manual access.
EDM Creates the Feature. AFM Helps Finish It.
Electrical discharge machining is often chosen because conventional tooling cannot efficiently create the desired feature. But the EDM process can leave a thin recast layer on the finished surface.
Removing that material can be challenging for the same reason the feature was difficult to manufacture: access.
AFM solves this problem by allowing the finishing media to follow the component geometry.
Abrasive Flow Machining Advantages
During AFM, abrasive particles suspended in polymer media pass through the selected region of the workpiece.
The process can be used to:
- Remove EDM recast
- Smooth EDM-produced surfaces
- Reach narrow internal passages
- Finish intersecting features
- Improve consistency across multiple components
- Maintain required geometry
Tooling and process parameters allow Extrude Hone AFM to control where and how the media works.
Applications for Las Vegas-Area Manufacturers
Precision machining operations in southern Nevada can serve aerospace, defense, transportation, energy, industrial equipment and other specialized markets.
When EDM is used to produce intricate component geometry for these applications, Extrude Hone AFM can perform the specialized post-EDM finishing work.
AFM can be particularly valuable for parts that would otherwise require difficult or inconsistent hand polishing.
Defined Results, Not Indiscriminate Material Removal
The objective of AFM is controlled finishing.
In suitable applications, AFM can improve a surface from around 1 micron (40 Ra) to approximately 0.1 micron (4 Ra) while preserving required geometry.

FAQs
Can AFM remove recast from both simple and complicated EDM parts?
Yes, although AFM provides particular advantages on complicated geometry and surfaces that are difficult to reach conventionally.
Do you process different metals?
AFM can be applied to many metals and alloys. Media and process parameters are selected according to the workpiece.
Where does Extrude Hone AFM perform the service?
Components are processed at Extrude Hone AFM's facility in Paramount, California.
