INDEX has announced the launch of the next generation of its TRAUB TNL12 sliding-headstock lathe for small part machining.
"Representing a comprehensive evolution of the machine, the new TNL12 incorporates a plethora of design changes that boost speed, flexibility and accuracy. The new machine provides an especially strong value proposition for medical manufacturers responsible for producing implants, bone screws and instruments for minimally invasive surgery," said a company spokesperson.
Like its predecessor, the TNL12 features four tool carriers that can be applied to a workpiece simultaneously, albeit with significant changes to the machine's kinematics. While the front-working attachment and counter spindle were previously arranged on a single slide, they are now housed on separate slides. This eliminates potential interdependence between front-end and counter spindle machining, allowing for greater flexibility in programming. Additionally, this design reduces the mass of both elements, allowing for faster and more dynamic machine response.
The features enabling rear-end machining also have undergone substantial changes. While the former model of the machine offered X-axis machining on the counter spindle, the new TNL12 provides full 3-axis machining in this position. A new back-working attachment offer six tool stations, with up to four allowing live tooling, as well as a flushing unit.
Overall tooling capacity has also been increased, with the capability to house up to 40 tools with the use of double and triple holders. This allows operators a greater degree of freedom to optimize machining of highly complex parts. Each of two 6-station tool turrets has its own servomotor and interpolated Y-axis, with chip-to-chip tool change times reduced to just 0.3 seconds.
While the previous generation TNL12 used belt drives on the main and counter spindles, the new machine incorporates fluid-cooled motor spindles with a maximum speed of 12,000 RPM. The TNL12 also offers higher dynamic response due to 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.
Refinements to the TNL12's overall structure include a nonhydraulic design, gray cast iron bed and thermo-symmetrical design that increases thermal accuracy and reduces warm-up times. These and other features combine to increase the stability of the machine, resulting in higher accuracy and shorter cycle times.
The TNL12 includes 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 for special applications. Coolant is cleaned by a compact belt filter, and users can choose between a tray or conveyor for chip removal.
To maximize the potential for unmanned operation, the TNL12 offers options for automated rinsing, part removal via a small gripper and removal of long parts through the counter spindle. The machine can also be paired with a robot for machining of chucked parts. Furthermore, the machine can be equipped with an optional whirling unit with a +/- 30° swivel angle for high-speed whirling to a length of 75 mm.
The TNL12 incorporates the current TRAUB TX8i-s control, which offers Industry 4.0 connectivity via INDEX's iXworld platform. The folding and swiveling operating panel includes a 19" touchscreen and provides easy access to a networked production environment.
Users of the previous model of TNL12 will find it easy to implement the new machine within their operations, since it is backwards compatible with its predecessor's toolholders for the turret and front- and back-working attachments.
