TRAUB TNL 12: Sliding-headstock CNC lathe

The next generation Traub TNL12 sliding-headstock lathe provides a strong value proposition for medical manufacturers responsible for producing implants, bone screws, and instruments for minimally invasive surgery.

The front-working attachment and counter spindle are now housed on separate slides, eliminating the potential interdependence between front-end and counter spindle machining and allowing for greater programming flexibility. Additionally, the design reduces the mass of both elements, allowing for faster, more dynamic machine response.

While the former model offered X-axis machining on the counter spindle, the updated TNL12 provides full 3-axis machining in this position. A new back-working attachment offers six tool stations, with up to four for live tooling, as well as a flushing unit.

Overall tooling capacity was increased, with the capability to house up to 40 tools with the use of double and triple holders, enabling more optimized machining of highly complex parts. Each of the two 6-station tool turrets has its own servomotor and interpolated Y-axis, with chip-to-chip tool change times reduced to 0.3 seconds.

This TNL12 incorporates fluid-cooled motor spindles with a maximum speed of 12,000rpm and offers higher dynamic response from low-mass clamping cylinders and a carbon sleeve for the guide bushing drive. The guide bushing is freely selectable, live or programmable, with the ability to adjust itself via a pneumatic servo valve.

Included is an 8-bar coolant pump, with the option to add one or two adjustable pumps capable of 20 bar to 120 bar; a 250-bar pump is also available. Coolant is cleaned by a compact belt filter and users can choose between a tray or conveyor for chip removal. The machine can also be equipped with a whirling unit with a ±30° swivel angle for high-speed whirling to a length of 75mm.

The TRAUB TX8i-s control is included.
