ALTEC RECTIFICATION
Leading specialist, Ø 2–25 mm, all critical materials
Expertise forged by industrial history
The bar straightening expertise developed by ALTEC ÉTIRAGE, strengthened by the acquisition of Établissements Chevreuil, guarantees product straightness and excellent dimensional repeatability.
This straightening mastery is integrated into the centerless grinding process; each bar follows a validation path from straightening onwards. This heritage enables understanding of bar behaviour (internal stresses, deformation) and adaptation of grinding parameters.
