Lots de petite taille – Diminution des changements d'outils grâce aux outils combinés
Corps de valve EN-GJL-300 – Alésage de tiroir
Situation initiale du client
- Petits lots
- Possibilité de régler l’outil
- Changement d'outil trop fréquent/fréquent
- Taux horaire élevé des machines
- Frais élevés en raison du processus de pierrage
Special features of this solution
- Tool change reduced due to multi-stepped boring tool with indexable inserts
- The contour can be completed in one processing step
- The fine boring tool creates highest bore quality and compensates the axial offset of the bores with pre-machining from two sides
