Die Cleaning (AFM Machines)

We work closely with 4mi Surface Solutions to supply Abrasive Flow Machining (AFM) solutions. An engineered solution customized to solve your finishing applications.

AFM machines and AFM media are much more than a deburring and finishing system. They are capable of achieving an 80% improvement in surface finish. An important part of die handling along with die ovens.

AFM Machines

Abrasive flow deburring machines for interior surface finishing.

Abrasive Media

Abrasive flow media for use in extrude honing machines.

Spare Parts

Suppliers of all AFM machine spare parts for all AFM machines (not just 4mi).

Why Choose a 4mi AFM Extrude Honing System?

Don’t your dies deserve the best?

4mi machines can remove less than 25 Microns of material to attain an ultra high purity finish, even in inaccessible internal areas. It’s more than a technology that can maintain tight aerospace tolerances.

  • Automatic die finishing increases aluminium extruder productivity
  • Easily handle intricate die shapes
  • Reduce surface imperfections and enhance quaility
  • Reduce die polishing time by up to 80%
  • Extend die life
  • Lower scrap
  • Uniform finish

What is Abrasive Flow Machining?

Abrasive flow machining (AFM), also known as abrasive flow deburring or extrude honing, is an interior surface finishing process characterized by flowing an abrasive-laden fluid through a workpiece. 

This fluid is typically very viscous, having the consistency of putty, or dough. AFM smooths and finishes rough surfaces, and is specifically used to remove burrs, polish surfaces, form radii, and even remove material.

The nature of AFM makes it ideal for interior surfaces, slots, holes, cavities, and other areas that may be difficult to reach with the polishing or grinding processes.
