Precision
Präzision und minimalste Krafttoleranzen durch spanabhebende Fertigung
- Die Federrate einer gewickelten Feder liegt in einem Toleranzfeld von +/-10%, während maschinell gefertigte Federn im Bereich von +/- 5% liegen. Kundenspezifisch können wir so auch Präzisionsfedern mit einer Toleranz von +/-1% herstellen.
- Spanabhebende Herstellungsverfahren erzeugen keine inneren Spannungen, welche zur Krafteinleitung erst überwunden werden müssen.
Maximum individualization
Maximale Individualisierung dank freier Materialwahl und CNC-Technik
- Die CNC-Fertigung ermöglicht maximale Individualisierung in Bezug auf Abmessungen, Federrate und Geometrie.
- Da sämtliche zerspanenden Materialien eingesetzt werden können, steht eine breite Auswahl an Werkstoffen zur Verfügung. Nebst herkömmlichen Materialien können auch leichte Aluminiumfedern, elektrisch isolierende Federn aus Kunststoff oder sogar hochfeste Titanfedern hergestellt werden.
Improved dynamics
Verbesserte Dynamik, zum Beispiel durch mehrgängige Wendel
- Mit einer mehrgängigen Feder lassen sich Bauteile herstellen, die Druck-, Zug- und Torsionskräfte zur gleichen Zeit aufnehmen können.
- Bei mehrgängigen Federn wird der Druck, resp. der Zug auf mehrere Punkte verteilt, was zu einer gleichmässigen parallelen Kraftverteilung führt. Da es so zu keinem unerwünschten seitlichen Ausknicken der Feder kommt, erübrigt sich eine zusätzliche Führung der Feder.
Function integration
Verringerter Montageaufwand dank Funktionsintegration im Bauteil
- Die Integration von Zusatzfunktionen (z.B. Bohrung, Gewinde, Flansch oder Nuten) optimiert den Einbauraum und vereinfacht Baugruppen massiv.
- Integrierte Anschlüsse (z.B. Flanschende, Nuten, Gewindebohrungen/ -zapfen, etc.) erhöhen die Stabilität der Feder.
Increased service life
Erhöhte Lebensdauer durch Optimierung der Wendelgeometrie an Start- und Endbereich
- Durch «Verdicken» des Wendelauslaufs kann die Festigkeit der Feder im kritischen Bereich erhöht werden.
- Durch Einsatz der Finite-Elemente-Methode (FEM) können präzise Aussagen zu Festigkeit und Lebensdauer gemacht werden.
