Our process

Extrude Hone AFM: The Leaders in Abrasive Flow MachiningAs the nation’s top AFM experts, we’ve continued to improve our process over the years. Now it’s absolutely outstanding, and when you send a component or two to Extrude Hone AFM, you’ll notice a dramatic improvement in performance right away.

We’ll gladly handle all your extrude honing needs, including:

  • AFM
  • EDM Recast Removal
  • Surface finishes and materials
  • AFM tooling
  • EH media


Extrude Hone AFM is most known for its AFM process. During this process, specially-designed abrasive media is sent through a workpiece with a ram, which results in erosion in every hard-to-reach crevice. Each AFM process is unique because each workpiece is different. The highest material removal happens wherever the flow is restricted because the flow speed and pressure of the media increase in smaller areas. The media exerts pressure on all surfaces, resulting in a uniform finish on all parts of the workpiece.

EDM Recast Removal

Another one of our popular services is EMD recast removal. We remove EDM’s recast layer from molds, dies, and other parts machined by this method. Extrude Hone AFM offers surface finishes that can resist stress crack propagation. For mold and dies, this helps to form process and part release. With our EDM recast removal process, it’s possible to polish a 1 micron (40Ra) surface finish down to a 0.1 micron (4Ra) surface finish without altering the required shape of the workpiece.

Surface finishes and materials

The surface finish of any given material is highly important, and making sure that surface is polished perfectly makes a huge difference – particularly in medical, food processing, and various other applications. Microscopic jagged edges can alter flow, cause foreign object damage, and even can result in contamination. We at Extrude Hone AFM improve surface finish to a desired target while precisely staying within blueprint specifications.

AFM tooling

AFM tooling facilitates precise, repeatable abrasion. Each tooling application is specially designed to contain the process as operations are conducted on the workpiece.

EH Media

Our specially-formulated new finish machining tool, which is a plastic, abrasive-laden polymer with very rheological properties is adjusted for every application. It can provide a wide range of results from fine honing to aggressive surface removal, depending on each client’s intended outcome. Viscosities, speed, and pressure can vary for each intended application. That’s why each application is custom-designed.
