Abrasive Flow Machine (AFM) uses pressurized abrasive media to efficiently polish and deburr complex internal surfaces and channels, making it ideal for precision components with intricate shapes and structures.

AFM Features

Machine for Solving Complex Polishing

The Abrasive Flow Machine (AFM), with its unique flexible abrasive flow technology, effectively addresses the deburring and finishing challenges of traditional polishing methods, especially for complex cavities, narrow channels, and intricate surfaces.

Adapt to complex shapes

Flexible contact, can fill any shape of gaps and holes under pressure

Even polishing

Adjustable polishing intensity, consistent cutting force on the surface

Batch Processing

Dozens to hundreds of parts can be processed at a time.

Super fine surface

Ra can reach 0.01μm (mirror grade), improving the smoothness.

The Abrasive Flow Machine (AFM) is the only machine that can simultaneously polish inner holes, curved surfaces, and blind holes.

Inner hole

Abrasive Flow Machines (AFM) deliver comprehensive polishing by utilizing a flexible abrasive flow, excelling especially at polishing inner holes that are difficult to access with traditional methods.

Irregular shape

Abrasive Flow Machining (AFM) technology can perfectly adapt to various irregularly shaped workpieces, such as impellers, turbines, and other complex geometric structures, achieving uniform polishing without dead angles.

Complex Structure

For precision parts with complex structures, the Abrasive Flow Machine (AFM) can simultaneously process multi-channel and multi-surface features, significantly enhancing the overall surface finish of special-shaped components.

Internal Curved Surface

The unique fluid dynamics design allows abrasive flow machining to precisely conform to curved surfaces, achieving mirror-level finishes.

Cross hole

In cross-hole polishing applications, the fluid polisher automatically adjusts the abrasive flow direction to effectively remove burrs and ensure uniform treatment of cross-hole areas.

Mould

As a revolutionary solution for mold polishing, Abrasive Flow Machining (AFM) can repair EDM lines and eliminate stress concentrations. It is particularly suitable for the final finishing of precision molds, such as injection molds and die-casting molds.

History of Abrasive Flow Machine (AFM)

The Abrasive Flow Machine (AFM), developed in the 1960s for aerospace applications, uses a viscoelastic medium with abrasives to polish complex parts, such as inner and cross holes, that traditional methods cannot reach.

Over time, Abrasive Flow Machine (AFM) has evolved from manual operations to CNC automation, now widely used in industries like medical equipment, automotive molds, and precision gears. Today, theAbrasive Flow Machine (AFM) can process tough materials such as stainless steel and titanium alloys, achieving a mirror finish with Ra≤0.1μm, making it essential for producing high-value parts.
