Using abrasive flow machining, Extrude Hone AFM can send abrasive-filled polymer media through internal passages, allowing the finishing action to reach cross holes, intersections, and other areas that conventional deburring tools may not access effectively.
Internal Burrs Require a Different Tool
Machining often produces burrs at the edge where material is cut.
When that edge is external, there are many ways to remove it.
When the same burr is located at an intersection deep within an aerospace component, hydraulic manifold, or fluid-handling part, the available options become much more limited.
AFM effectively turns a conformable abrasive media into the deburring tool.
Because the media follows the component's internal geometry, it can contact features regardless of whether an operator has direct visual access.
Potential Flow Deburring Applications
Extrude Hone AFM can evaluate components containing:- Internal cross holes
- Fluid passages
- Cooling channels
- Hydraulic galleries
- Valve features
- Precision cavities
- Dies and molds
- Pump and turbine passages
AFM can remove burrs and, where appropriate, create controlled edge radii or improve surface finish.
Serving Denver and Front Range Manufacturers
Denver and Colorado's Front Range support substantial aerospace, medical, energy, electronics, and advanced manufacturing activity.
These sectors routinely use high-value precision components where internal features can be critical to performance.
A burr in a cooling channel, flow passage, or precision manifold may be inaccessible but still need to be addressed.
Extrude Hone AFM provides manufacturers with a specialized external resource for these applications.How the Process Is Controlled
The flexibility of AFM does not mean the process is uncontrolled.
Successful abrasive flow machining depends on carefully determining where media should flow and how aggressively it should work.
Variables include:
- Workpiece geometry
- Material
- Media viscosity
- Abrasive characteristics
- Tooling
- Passage restriction
- Number of cycles
Repeatable Edge Conditioning
A production component may contain the same internal burr after every machining cycle.
Using manual deburring to remove that burr repeatedly can introduce labor and variation.
AFM offers a process that can be established and repeated under controlled conditions.
This can make it valuable for both specialized precision components and larger production programs.

FAQs
Can AFM reach cooling passages?
Potentially, yes. Internal cooling and fluid passages may be good candidates when tooling can direct media through the required pathway.
Does AFM always round the edge?
The degree of edge conditioning depends on how the process is developed. Extrude Hone AFM can evaluate the required edge condition.
Does Extrude Hone AFM serve Colorado?
Yes. Extrude Hone AFM provides AFM services nationwide from Paramount, California.
