With the patented SFFS straightening technology [Shear-Force-Free-Straightening] the required process forces are introduced exclusively via the material ends. This means that, among other things, finished products can be straightened without straightening marks on the surface. It is essential that residual stress in the material is reduced as a result of the shear force free straightening technology.The straightening process is applicable for the following materials:- Metallic bars, tubes and hollow profiles with rotation symmetric or almost rotation symmetric cross-section- Finished- and semi-finished products as well as raw materialsSERIESSFFS 30 - 2.000[cross-section 10 - 30 mm| length 300 – 2.100 mm]SFFS 30 – 3.000[cross-section 10 - 30 mm| length 300 – 3.100 mm]SFFS 50 – 2.000[cross-section 15 - 50 mm| length 500 – 2.200 mm]SFFS 50 – 3.000[cross-section 15 - 50 mm| length 500 – 3.200 mm]FEATURESWIDE RANGE OF APPLICATIONSStraightening of semi-finished products and already machined parts, e.g. lead screws, racks, etc.SUPERIOR SURFACE QUALITYNo straightening marks due to shear force free straightening technology -> straightening/post-straighteningof finished parts possible.REDUCTION OF RESIDUAL STRESSDue to the SFFS straightening technology residual stress in the material will be reduced -> advantagefor subsequent machining of the straightened materials.VARIABLE MACHINE CONCEPTSStandalone solutions up to fully automatic production cells -> straightening automats with manual or robothandling, with integrated straightness control unit, linked with automatic lathes with bar loader, etc.
