Abrasive Flow Machining Services

Polishing and deburring complex internal shapes can be difficult. Due to the intricate nature of complicated parts, standard finishing techniques do not work. Abrasive Flow Machining (AFM) services, also referred to as abrasive flow deburring, abrasive flow grinding, and extrusion honing, provide high-quality finishing, deburring, or radius complexing in the fraction of the time required by other methods.  Since the media application is extremely precise within the abrasive flow machining process, highly inaccessible areas can be reached, allowing for the processing of multiple holes, slots, or edges.

At Arrow Cryogenics, no Abrasive Flow Machining job is too big or too challenging. We have the resources and expertise to provide complete AFM turnkey services for large- or small-scale projects that utilize parts and components of all sizes.

Contact us for more information regarding Abrasive Flow Machining services, or call us at 763-780-3367 and one of our expert AFM specialists will assist you. With nearly 40 years of top-quality Abrasive Flow Machining experience, Arrow Cryogenics is your trusted source for precision Abrasive Flow Machining services.

Abrasive Flow Machining Process

AFM utilizes two opposed cylinders that force abrasive media through workpiece and tooling passages. The abrasion operates only within the extrusion area where the flow is restricted. The machining action of AFM is comparable to grinding or lapping, where abrasive media gently and uniformly smooths material edges and surfaces. Both soft and hard metals benefit from abrasive flow machining services. The rate of material removal depends on the following factors:

  • Viscosity
  • Media flow rate
  • Particle density
  • Particle hardness
  • Workpiece hardness
  • Abrasive particle size
  • Abrasive concentration

Media Sizes & Viscosity

Depending on the application, media of differing viscosities can increase flow rate, allowing for material edges to be abraded more than the passage walls. AFM media consists of abrasive grains that are combined with a workable semisolid carrier. The flow pattern can be adjusted based on the machine settings, media formulation, and workpiece and tooling configurations. Higher viscosity media is used for uniformly abrading the walls of large passages. Lower viscosity media is generally appropriate for radiusing edges and for processing small areas.
