Stäheli AG | Entgraten und Polieren auf höchstem Niveau
down to
the detail.
Our passion.

Whether it’s in medical engineering, sensor technology or aerospace: to guarantee smooth operation, precision parts require the perfect finish through deburring or polishing.

Abrasive Flow Machining:
Satisfying Precision.

Particularly when working on complex workpieces with spots, boreholes and internal surfaces that are difficult to access, abrasive flow machining is the only way to ensure even and reliable machining.

How abrasive flow
machining works.

We use a paste containing abrasive particles to remove the finest burrs and polish raw surfaces. 

This paste is repeatedly pressed through the part or guided over the surface to be machined. We build custom devices for the targeted machining of specific batches for every customer product. 

For you, that means high-quality polished surfaces, perfectly deburred edges, chamfered boreholes and openings that meet the highest quality standards.
