Precision straightening — complex parts and high requirements

Transmitted know-how, applied to today's industrial requirements

Établissements Chevreuil specialise in precision straightening of individual parts or small series, when tolerances are tight, geometries complex and standard solutions are no longer sufficient.

Nearly 100 years of know-how transmitted across four generations form today the foundation of our approach. This ancient knowledge, born from the field and from experience, is applied to current industrial requirements within a rigorous and controlled technical framework.

When straightening becomes a trade in its own right

Precision straightening is not just about making a part straight again. It is about understanding its actual behaviour, its internal stresses, its final function and the limits not to be crossed.

We intervene when:

• the required straightness or flatness is high,
• the part presents simple or combined deformations,
• the material or metallurgical state requires a cautious approach,
• preservation of surfaces and absence of marking are essential.

In some cases, targeted tolerances can reach a few hundredths, requiring rigorous mastery of the process and control at every step.

Varied parts, shapes and defects

We work in particular on:

• shafts, axles and long rods,
• plates and flat parts,
• rings and annular parts, which may present combined defects of flatness, ovality and umbrella effect,
• tubes, by internal, external action or de-ovalization,
• atypical parts requiring specific processes defined with the client.

Materials may be ferrous or non-ferrous, in varied states, including treated, work-hardened or coated, with particular attention paid to surface preservation.
