Manufacturers requiring EDM recast removal in Indianapolis, IN can use Extrude Hone AFM's abrasive flow machining process to finish complex surfaces that are difficult to reach using conventional tools.
AFM can follow internal passages and intricate geometry while removing controlled amounts of material, making it well suited to many EDM-produced components.
What Is Left Behind After EDM?
Electrical discharge machining creates shapes through precisely controlled electrical discharges. During the process, material can melt and then resolidify on the component surface.
This thin affected surface is known as the recast layer.
For parts with demanding surface specifications or operating requirements, the manufacturing plan may include removal of that layer.
Why AFM Is Well Suited to Recast Removal
AFM replaces the rigid finishing tool with a flexible abrasive media.
The media flows through the workpiece, conforming to its geometry and abrading the surfaces along the controlled flow path.
The process can be particularly effective for:
- Deep passages
- Cross-drilled holes
- Intersections
- Internal cavities
- Detailed tooling
- Dies and molds
- Complex precision components
Applications for Indianapolis Manufacturing
Indianapolis and central Indiana support major automotive, aerospace, medical, motorsports and industrial manufacturing operations.
These sectors frequently require precision components with complicated geometries.
Where EDM is used to produce those geometries, Extrude Hone AFM can provide specialized finishing to remove recast and improve the resulting surface.
Consistency for Production Components

For suitable applications, AFM can improve an approximately 1 micron (40 Ra) surface toward approximately 0.1 micron (4 Ra) while maintaining required geometry.
