Aircraft fuel injector: high-precision micro-drilling

In the aerospace industry, the performance of fuel injectors relies on extremely precise micro-drilling. STEEC supports manufacturers in creating critical micro-holes, whether on existing parts or as part of the complete manufacturing of injectors.

Thanks to its advanced technologies (CNC machining, micro-electro-erosion, laser) and its recognized expertise, STEEC guarantees reliable, reproducible results that meet the strictest requirements of the aeronautics sector.

Micro-drilling of aeronautical injectors: a critical issue

THE micro-drilling of fuel injectors plays a key role in:

the quality of fuel atomization
energy efficiency
the reduction of emissions
combustion stability

These applications require drilling of a few tens of microns, perfectly controlled in geometry, repeatability and surface finish.

We work on high-value-added parts requiring a micrometer precision and absolute reliability.

our micro-drilling technologies

CNC machining

CNC machining allows for drilling and tapping of very small dimensions with excellent repeatability, ideal for small and medium series.

Micro-electro-erosion

Micro-electrical erosion (EDM) offers extreme precision, particularly suited to hard or complex materials, without generating mechanical stress on the part.

Laser micro-drilling

Laser micro-drilling allows for very high precision with high execution speeds, ideal for specific geometries and mini-tubes.

Over 45 years of expertise in precision micromechanics serving the most demanding applications.
