TRAUB TNL 18 HORIZONTAL MACHINING CENTER

Technical Description

The TRAUB TNL 18 is a precision CNC Swiss-type automatic lathe engineered for small-to-medium component manufacturing with exceptional accuracy and speed. Featuring a single main spindle with 12,000 RPM capability and 7.40 HP, supplemented by a dedicated sub-spindle operating at identical speeds with 3.40 HP, this machine enables simultaneous multi-axis machining operations. The system accommodates workpieces up to 0.790" in diameter with maximum turning lengths of 8.070", utilizing bar stock up to 0.790" diameter. Equipped with dual turrets—an upper turret with 24 turning tools and 16 rotary tools, plus a lower turret with 21 turning tools and 10 rotary tools—the TNL 18 supports up to three simultaneous cutting tools for enhanced productivity. With eight standard axes expandable to nine, the machine features smooth XYZ axis travel of 4.720", 2.360", and 8.070" respectively, with rapid traversal rates reaching 787 IPM. Integrated milling and drilling capabilities function both on-center and off-center with full C-axis and Y-axis support, providing comprehensive turn-mill functionality. The rotary tool stations deliver 2.66 HP at 12,000 RPM on the primary carrier and 3.25 HP on the secondary, enabling complex geometries and tight tolerances. The machine's compact footprint of approximately 3060 x 1480 x 2420 mm with 4,300 kg weight and 24 kW power draw makes it suitable for high-precision applications in medical, automotive, and aerospace industries requiring rapid setup changes and outstanding part repeatability.
