Description

TWN-Heavy Boring Head 75°, Roughing Boring Head, Spindle Head

Anyone who wants to bore through holes in the range of 25 to 90 mm with high feed rates and large depths of cut needs a boring head that controls cutting forces instead of transmitting them to the tool holder. The TWN rough boring head 75° delivers exactly that: its flatter lead angle directs most of the resulting force axially into the spindle, significantly reducing radial load and thus deflection tendency – a decisive advantage over 90° designs, especially in deep bores and long overhangs.

The TWN heavy series is designed with a compact, high-mass base body and vibration-damping cartridges. Two cutting edges with positive geometry remove a correspondingly high volume per revolution without excessively loading the machine. The fine adjustment in 0.02 mm increments gives the operator control over the finishing allowance, while the integrated internal coolant supply not only increases the tool life of the indexable inserts but also actively supports chip evacuation from deep bores. The open chip space design shows its strength particularly with tough, long-chipping materials, where chip congestion would otherwise quickly compromise the process.

For heavy-duty machining of through holes with axially optimized force flow and manufacturer-independent ISO insert compatibility, the TWN 75° boring head is a process-reliable investment that quickly pays off through reduced setup times and higher cutting data.

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

TWN-Heavy 75 Grad überzeugt

Der TWN-Heavy mit 75° Einstellwinkel bringt im Schruppen richtig Abtragsleistung, der Werkzeugkörper ist massiv und läuft auch unter hoher Last ruhig. Hab ihn auf der Doosan in 42CrMo4 eingesetzt, Schnitt war sauber und keine Rattermarken. Werde definitiv weitere Varianten nachbestellen.

Passt bisher

Aufbohrkopf mit 75°-Hauptschneide, erster Test gut. Für ein endgültiges Urteil noch nicht lange genug in Betrieb, Tendenz positiv.

Funktioniert einwandfrei

Nach kurzer Einstellung läuft der Kopf rund. Läuft bei mir auf der Doosan Puma 2600 ohne Probleme. Ordentliche Wiederholgenauigkeit. Kein nerviges Gequietsche wie bei manchen anderen Werkzeugen. Mit der Lieferung lief ebenfalls alles reibungslos. Gerade bei dem Preis echt eine runde Sache. Kann ich so weiterempfehlen.

Vorerst überzeugt

Preis-Leistung ist in Ordnung, das Werkzeug fügt sich in meinen Werkstattablauf ein, Langzeiteinsatz muss sich zeigen. Das Preisschild überzeugt, die Qualität auch.

Heavy-Aufbohrkopf 75° effizient

Für größere Durchgangsbohrungen im Bereich 25-90 mm sehr gut geeignet. Der Kopf läuft stabil auch bei großen Schnitttiefen und hohem Vorschub. Die Oberflächen sind ordentlich für das Schruppniveau.
