Description

TWN-Heavy Boring Head, Roughing Boring Head, Spindle Head

The TWN rough boring head is a heavy-duty boring head with a 90° lead angle, specifically developed for boring blind holes in the diameter range of 25 to 90 mm. As a robust two-edged boring head, it is aimed at users who require maximum material removal rates during pre-turning and roughing of bores while maintaining process reliability – even in interrupted cuts or demanding clamping situations.

The solid base body and compact cartridges form a rigid system that effectively suppresses vibration tendencies even under aggressive cutting data. The positive cutting geometry of the ISO standard indexable inserts used significantly reduces cutting forces, which directly results in lower spindle wear and smoother running. The fine adjustment allows precise setting of the bore diameter in 0.02 mm increments – enabling tight stock allowances for the subsequent finishing pass already during roughing. The integrated internal coolant supply directs the coolant precisely to the cutting zone, reducing built-up edge formation and extending the tool life of the indexable inserts. Generously dimensioned chip spaces ensure reliable chip evacuation, even with long flowing chips, without compromising the process.

Anyone looking for a reliable boring head for heavy-duty machining of blind holes and who values manufacturer-independent indexable insert compatibility will find an economical and field-proven solution in the TWN heavy series.

Scope of delivery: 1 boring head (without indexable inserts), 2 Torx screws, 1 Torx key, 2 hex keys.

Schruppbohrkopf aufbohrt ruhig

Der Schruppbohrkopf macht sich im Einsatz gut. Selbst bei ordentlicher Zustellung bleibt das Ganze stabil. Leichte Einstellung am Kopf. Rundlauf passt, Späne werden zuverlässig abgeführt. Für größere Bohrungsdurchmesser eine solide Lösung.

Robuster Aufbohrkopf

Der TWN Schruppbohrkopf nimmt richtig Material weg. Stabile Konstruktion und ruhiger Lauf auch bei größeren Zustellungen. Für Aufbohrarbeiten in der Serienfertigung sehr gut.

TWN-Heavy Aufbohrkopf im Dauereinsatz

Den TWN-Heavy Aufbohrkopf habe ich auf unserer Okuma LB3000 in größeren Bohraufgaben getestet, der Kopf verteilt die Schneidkräfte gut und schafft zügige Zerspanungsleistung auch bei größeren Aufmaßen. Die Verarbeitung ist sehr wertig, die Wiederholgenauigkeit stimmt auch nach vielen Einsätzen, für unsere Schruppbohrungen ein Werkzeug das sich rechnet.

Schwere Aufbohrkopf-Variante überzeugt

TWN-Heavy Aufbohrkopf für große Durchmesser und kräftige Zustellungen. Bei Reparaturen an großen Gehäusen die richtige Wahl, Stabilität und Kraftübertragung beeindrucken. Rundlauf ist bei der Größe beeindruckend stabil.

Bisher top

Aufbohrkopf laesst sich sauber einstellen. Ruhiger Lauf. Standzeit geht für den Einsatz völlig in Ordnung. Würde ich jederzeit wieder nehmen.

Heavy-Aufbohrkopf für Formbauteile sehr stark

Den Schruppbohrkopf setze ich auf einer Makino a81M beim Aufbohren großer Formgehäuse-Durchmesser ein und bin mit dem Ergebnis sehr zufrieden. Das Werkzeug verträgt deutliche Schnittleistungen ohne zu vibrieren, die Platten halten und der Vorschub-Zuwachs ist spürbar. Für schwere Zerspanung im Werkzeugbau eine klare Empfehlung.
