What Is Abrasive Flow Machining?
Abrasive flow machining (AFM) is a finishing process that removes burrs and unwanted material from a workpiece. The AFM process utilizes an abrasive flow medium – a semi-solid putty or dough-like material that contains abrasives of various grit sizes. AFM is used to finish complex workpieces with areas that are difficult to reach using other finishing methods.
During the AFM process, a hydraulic ram forces the abrasive media through or across the workpiece. As the abrasive media is extruded along the surface or interior of the workpiece, it polishes away burrs, removes unwanted material, improves flow characteristics, and helps form radii. AFM is used for a wide range of applications, including dies, semi-conductor valves and fittings, engine parts, and medical devices to name a few.
Deburring and Finishing Technologies is a Leading Provider of AFM Services
Deburring and Finishing Technologies is a leading provider of AFM services. Our AFM processes deliver high-quality, defect-free parts that meet or exceed our clients’ specifications. Some of our AFM services include:
Polishing/deburring – our AFM processes to polish the workpiece while removing burrs and unwanted material
Abrasive Flow Machining – AFM provides a higher quality of finish than other machining finishing processes
Diesel spray nozzles – AFM can be used to break in newly EDM’ed spray holes or to increase the horsepower of diesel engines
EDM “recast” removal – a finishing process that removes the recast layer from molds, dies, and other parts.
In addition to our outstanding AFM services, Deburring and Finishing Technologies provides abrasive media, new and used AFM machines and other AFM solutions to manufacturers across the nation and around the world.
We are an Abrasive Flow Media Company based In the Eastern United States
Abrasive flow media is critical to the AFM process. An abrasive flow medium is a semi-solid putty-like material that consists of one or several abrasive materials mixed with a base polymer or carrier. The abrasive materials can range in size from fine talcum-like particles to objects the size of small rocks or pebbles.
Deburring and Finishing Technologies offer customers several different types of abrasive flow media to select from.
Are You Experiencing Issues with Your Current Supplier?
Is the abrasive flow media you’re currently using clogging or separating?
Deburring and Finishing Technologies has the capability to tweak or re-engineer our media to fit your specific needs. We offer over 50 types of media for any situation. Our media comes in 3 ½ gallon or 5-gallon sizes.
Our Most Popular Media For Sale...
NM-1000-.33 small hole polishing/sizing in holes ranging from .005 to .020. Typical applications are diesel spray nozzles and fuel rails.
LV-150-1.5 (Low viscosity, 150 grit silicon carbide abrasive, at a ratio of 1.5# to 1# of the total chemistry) is one of our most widely used abrasive media. Typical applications are aluminum and vinyl extrusion dies for EDM “recast” removal with profile openings of around .020.
HV-54-2 is another popular choice. HV-54-2 has a very high viscosity and is stiff enough for large holes and castings, with a 54 grit abrasive of 2 to 1 to improve the finish in castings and large interior dimensions.
STM-1200-3 (shear thinning media) gel-like abrasive flow media for diesel spray nozzles.
DIAMOND ABRASIVE FLOW MEDIA is used for polishing of hard-to-machine carbide dies.
We Can Create Abrasive Flow Media Especially Suited for Your Project
Different applications require different abrasive flow media formulations. Deburring and Finishing technologies can engineer abrasive flow media specially formulated for your project needs. We have abrasive materials in grit sizes ranging from 8 to 1200 mesh.
