Abrasive flow machining provides access to internal passage intersections by forcing flexible abrasive media through the workpiece.
Why Hydraulic Deburring Requires Internal Access
A hydraulic manifold may contain many drilled passages even when the component is relatively compact.
Each intersection between those passages creates an edge that may need finishing.
Hand tools cannot always reach the location.
Even specialized brushes may produce uneven results if passage access differs throughout the component.
Extrude Hone AFM notes that conventional deburring can leave microscopic burrs behind, and those burrs may break loose during high-pressure operation and become contaminants.AFM is designed to solve that access problem.
How Abrasive Flow Deburring Works
A polymer media carrying abrasive particles is forced hydraulically through selected passages.
The media conforms to the available space and contacts the internal surfaces.
As it flows across raised edges, abrasive action gradually removes material.
Depending on the application, AFM can:
- Remove internal burrs
- Deburr cross-drilled passages
- Radius intersections
- Improve internal surface finish
- Reach hidden corners
- Process several connected passages
- Produce repeatable results
Manifolds With Large Numbers of Intersections
A complex manifold can contain far more intersections than could reasonably be addressed one at a time by hand.
Extrude Hone AFM's hydraulic FAQ specifically discusses a valve body with more than 100 intersecting holes.Purpose-built fixtures can route media through the holes and, in many cases, allow a majority of the intersections to be deburred and radiused together.
New York Precision and Industrial Applications
The New York metropolitan area supports aerospace, transportation, automation, medical technology, specialized machinery, robotics, and precision manufacturing.
Hydraulic systems used in these industries may require compact, sophisticated valve and manifold designs.
AFM allows manufacturers to finish the internal geometry without simplifying the component merely to accommodate a deburring tool.
Controlling the Process
Hydraulic AFM is highly customizable.
Extrude Hone AFM can alter:- Tooling
- Media-flow pressure
- Media carrier viscosity
- Abrasive concentration
- Abrasive particle size
- Processing cycles
The workpiece material, hardness, and passage configuration also affect removal rates.
Why Restrictions Matter
The AFM process naturally produces greater material removal where media flow is restricted because local speed and pressure rise.
Extrude Hone AFM's process guidance explains this behavior and uses it as part of the controlled finishing method.Tooling can therefore be designed to focus abrasive action where required.
Maintaining Dimensional Requirements
The objective is not to make passages unnecessarily larger.
Extrude Hone AFM works from customer specifications and can target burr removal, edge radiusing, or surface improvement while protecting critical geometry.Its hydraulic guidance specifically emphasizes staying within blueprint tolerance through proper planning.

FAQs
Can AFM reach an intersection that cannot be seen from outside the part?
Yes. The process uses the internal passage as the route for abrasive media.
Can custom tooling isolate certain passages?
Yes. Tooling is designed to establish and control the media flow path.
Does Extrude Hone AFM serve New York manufacturers?
Yes. Extrude Hone AFM serves manufacturers throughout the United States.
