Description

TWN Boring Head, Roughing Boring Head

The TWN series represents a new generation of boring heads, specifically designed for efficient and cost-effective rough boring. With their twin-edge design, these boring heads are ideally suited for demanding roughing and pre-finishing operations. The programme comprises eight boring heads that fully cover the diameter range from Ø 20 to 150 mm. A distinctive feature of this series is the fine adjustability of the diameter in 0.02 mm steps, which ensures outstanding accuracy in machining. Thanks to their compact and robust construction as well as a positive cutting geometry, the TWN series boring heads guarantee virtually vibration-free operation. This is particularly advantageous on interrupted cuts and at high cutting speeds.

Compared with single-edge finish boring heads, the twin-edge boring heads of the TWN series offer a performance increase of up to four times. They enable the machining of large stock allowances and high feed rates, while always ensuring optimal roundness and positional accuracy of the bores – two decisive factors in today's strict control of part geometry. Often, semi-finishing cuts can be omitted thanks to the balanced cutting force behaviour of the tools, even with strong casting core displacements.

The roughing boring heads use ISO standard inserts with positive cutting geometry to minimise cutting forces. The clamp-free fixing of the indexable inserts and the generous chip pockets ensure optimal chip formation and evacuation.

The TWN series stands out with the highest stability and precision, thanks to a special, ground-on-both-sides profile connection between the tool body and the indexable insert holder. With integrated internal coolant and ease of handling, the TWN series combines functionality with a compact design to master the most demanding machining tasks.

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

Aufbohrkopf für Schruppaufgaben solide

Für Schruppen gut geeignet. Der Aufbohrkopf macht bei größeren Bohrungen eine saubere Figur, Rundlauf passt. Verarbeitung ist ordentlich, bin zufrieden. Einstellbarkeit des Durchmessers ist praxistauglich, Sitz in der Spindel ist spielfrei.

Aufbohrkopf stabil

Der Schruppbohrkopf räumt größere Durchmesser zügig auf, Plattenklemmung bleibt fest. Bin mit dem Werkzeug zufrieden. Im Alltag in der Fertigung mit wechselnden Aufträgen und Werkstoffen zeigt das Werkzeug eine stabile Leistung, die Werkzeugausführung bleibt auch bei intensiver Nutzung über Wochen gleichmäßig.

Aufbohrkopf fair

Der Aufbohrkopf ist preislich moderat, Plattenklemmung hält gut. Für Kleinbetriebe wirtschaftlich. Der Griff zur günstigeren Variante lohnt sich.
