A structured approach by typology

Precision straightening is not applied the same way depending on the shape, geometry or function of a part. Our know-how is structured by main typologies, in order to adapt the analysis and method to each case encountered.

This approach enables:

understanding the actual behaviour of the part,
managing risks,
and defining a correction strategy coherent with the functional requirement.

A very wide range of dimensions and capacities

We work across a very wide range of dimensions.

Parts handled can range from a few millimetres for very small components, up to parts several metres long, depending on configurations encountered.

Forces applied are adapted to each case, thanks to means enabling intervention on both light and much heavier parts, with capacities that can reach up to several hundred tonnes.

This range requires permanent adaptation of methods, tooling and controls.

Often combined defects

Geometric defects are rarely isolated. The same part may simultaneously present:

a straightness defect,
a flatness defect,
an ovality,
or more complex deformations linked to internal stresses.

Precision straightening consists of identifying dominant defects and defining a global approach, rather than a piecemeal correction.

Part typologies encountered

Shafts, axles and rods

Long parts or parts with thin sections subject to straightness defects. The intervention takes into account the surface state, any heat treatment and coatings present.

Shaft straightening · axle straightening · rod straightening · shaft straightness

Plates and flat parts

Flatness correction on flat parts, with particular attention paid to preserving ground or treated surface states.

Plate straightening · plate flatness · flatness correction

Rings and annular parts

Parts that may present combined defects of flatness, ovality and umbrella effect. Each defect is analysed separately before defining a global correction strategy.

Ring straightening · oval ring · deformed ring

Tubes

Intervention by internal, external action or de-ovalization depending on the defect observed. The interior and exterior surface state is preserved as much as possible.

Tube straightening · tube de-ovalization · tube ovality correction · bent tube

Atypical parts

For parts that do not fall into standard typologies, we define a specific procedure in consultation with the client. Feasibility analysis is carried out beforehand.

A common logic: analysis, mastery, decision

Whatever the size or shape of the part, the approach always rests on the same principles:

prior analysis,

understanding of part behaviour,

progressive and controlled correction,

respect of surfaces and final function,

assumed technical decision.
