Surface finishes and materials

Extrude Hone AFM can finish any metal material to your desired target without exceeding the blueprint specs.

Surface finishes and materialsSurface finish is critical in any passageway that is depended on to perform efficiently and at a high level, regardless of whether it is fuel, air, oil, food, or even blood flowing through it. In every case flow will be affected by the positives and negatives or peaks and valleys left on the surface after conventional machining, casting, electrical discharge machining (EDM), or 3D selective laser sintered applications and these will dictate the performance and efficiency of the passageway for better or worse.

Unfinished surfaces can cause flow restrictions and contamination. In particular, microscopic jagged edges that can not only alter flow but cause foreign object damage as well.

Our main objective at Extrude Hone AFM is improving surface finish to a desired target while at the same time having the precision to stay within the blueprint specifications.

AFM can be applied to any metal material, including titanium or Inconel, super alloys, hardened, and difficult-to-machine materials as well as your softer metals such as aluminum, bronze and copper.

Our finishes vary and will be based on the geometry of passages and the type of material.

Typical Finish Improvements Consist of:

  • 16-8ra improved to a 3-4ra
  • 32ra improved to an 8ra or better
  • 64ra improved to a 16ra or better
  • 125ra improved to a 63ra or better
  • 300ra to a 125ra or better etc.
