A few years ago, ArianeGroup adopted abrasive flow machining (AFM) technology by acquiring a VECTOR machine.

A team headed by an expert in non-conventional finishing methods was set up.

With the Extrude Hone machine, various types of impellers and wheels are polished by AFM. 

The AFM technology benefit is that vanes can be polished in the direction of fluid flow.

The aim is to achieve a surface enhancement that improves laminar flow and reduces turbulence. 

Bubbles are the number one enemy of rocket engine booster pumps.

We wish Ariane 6 a long career.
