From the Manufacturer
Bringing Abrasive Flow Machining Solutions to the AM Metal Industry
We offer two-way flow AFM machines, MICROFLOW low-viscosity variation, tooling, and specially engineered media to address your AM finishing needs.
The AFM inventor, Extrude Hone, delivers surface improvement for AM components across all industries. Our solutions achieve partially sintered material removal, stress release, and improved roughness by up to 10 times.
We provide an extensive portfolio of machines scaled to different application requirements — from the MICROFLOW for precision small-orifice work to the SPECTRUM for large parts with complex requirements.

TCT Buyer Guidance
Questions for your Extrude Hone AFM evaluation
Do your parts have internal channels, passages, or features that require surface improvement? AFM is one of the few technologies capable of finishing internal geometries that are inaccessible to mechanical or manual finishing methods.
What surface roughness improvement do you need? AFM can improve roughness by up to 10×, but the achievable finish depends on starting roughness, geometry, material, and process parameters. Request application-specific test results before committing.
What is your production volume? The MICROFLOW suits precision work on small features; the VECTOR handles medium-volume production; the SPECTRUM is designed for large parts and high throughput. Matching the machine to your volume and part size is critical for economics.
