Abrasive flow machining can reach precision gas and fluid passages using flexible abrasive media that follows the component geometry.
This makes AFM useful for semiconductor-related equipment components whose internal surfaces cannot be finished reliably with conventional polishing tools.
Semiconductor Process Components Require More Than Machining
A valve, manifold, or fitting may meet its dimensional specifications while retaining unwanted microscopic surface features.
Machining can leave:
- Burrs
- Tool marks
- Cross-hole edges
- Rough passage walls
- Small cavities
- Surface peaks and valleys
For high-purity flow applications, reducing these irregularities can be an important post-machining step.
Extrude Hone AFM specifically identifies ultrapure fluid-handling components for semiconductor fabrication among its AFM applications.How Abrasive Flow Machining Works
The AFM process uses a polymer carrier filled with abrasive particles.
Pressure moves that media through the target feature.
The media conforms to the internal passage and abrades raised surface features.
Depending on the workpiece, AFM can provide:
- Internal polishing
- Cross-hole deburring
- Edge conditioning
- Smoother flow paths
- Surface-finish improvement
- Repeatable internal processing
Semiconductor Equipment Components
Potential applications include:
- Precision valve bodies
- Gas-delivery components
- High-purity fluid components
- Manifolds
- Fittings
- Cross-drilled bodies
- Internal flow channels
Each component is evaluated for geometry and accessibility before a process is established.
Indianapolis Advanced Manufacturing
Indianapolis and central Indiana support electronics, life sciences, aerospace, automotive, precision machining, and advanced manufacturing.
Companies in these sectors may produce specialized components used by semiconductor-equipment manufacturers elsewhere in the country.
AFM allows suppliers to outsource highly specialized internal finishing instead of maintaining their own abrasive flow machining equipment.
Surface Finish Capabilities
Representative AFM finish improvements published by Extrude Hone AFM include approximately:
- 16–18 Ra to 3–4 Ra
- 32 Ra to 8 Ra or better
- 64 Ra to 16 Ra or better
- 125 Ra to 63 Ra or better
Results depend on the workpiece.
The part's metal, hardness, starting roughness, and internal geometry all influence the final surface.
Internal Deburring for Precision Flow Paths
A cross-drilled valve body can contain burrs at intersections located well inside the component.
AFM avoids the need for direct tool access.
Media travels through the existing passage and contacts the burr from within.
This can also smooth the surrounding region, providing both edge and surface improvement.
Tooling and Selective Finishing
AFM tooling is designed to support the workpiece, control media flow, and protect non-target surfaces.
For high-value semiconductor equipment parts, this helps ensure that finishing is concentrated where it is required.
Materials
Extrude Hone AFM can evaluate AFM for titanium, Inconel, hardened metals, superalloys, aluminum, copper, bronze, and other suitable metal components.Supporting High-Purity Manufacturing
AFM improves the manufactured surface.
It does not replace downstream cleaning, cleanroom handling, inspection, or qualification.
Instead, it can help provide a smoother, deburred component for those subsequent processes.
