Kleine Losgrößen – Reduzierung der Werkzeugwechsel durch Kombinationswerkzeuge
Ventilgehäuse EN-GJL-300 – Schieberbohrung
Ausgangssituation beim Kunden
- Kleine Losgrößen
- Möglichkeit zur Werkzeugeinstellung vorhanden
- Zu viele/häufige Werkzeugwechsel
- Hohe Maschinenstundensätze
- Hoher Aufwand durch Dornhon-Prozess
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
Spool bore
1. Piloting and boring
- Multi-stepped boring tool with radial and tangential indexable inserts
- Pre-machining spool bore and completion of contours in one processing step
2. Control edge machining
- Solid carbide profile tool
- Highest accuracy and surface finish of control edges
- Defined control edges without macroscopic flaws
3. Fine boring
- Fine boring tool with indexable inserts and guide pads
- Ideal for bar machining of highly accurate and long bores
Advantages
- Optimally matched process due to solution with multi-stepped boring tool with indexable inserts, control edge machining and fine boring
- Best accuracy and process reliability
- Reduced effort when honing, resulting in cost savings
