TNA400 in focus


Control TRAUB TX8i-s

The open control concept with a superfast 64-bit processor ensures that you have your production under control at all times.

Whether tool breakage monitoring, realistic real-time simulation for shorter setup times or visual collision detection before running in the machine. The TNA400 has all this as standard.


The machine design

The kinematics

The TNA400 features a twelve-station disk-type turret with VDI40 shank, an extremely high degree of collision-free working due to a turret clearance of 420 mm and the Y-axis. The tailstock is part of the basic equipment; it can be manually positioned on the separate guideway and is operated hydraulically.
The major advantage offered by this concept, however, is still its working area: The travel of the X-axis is very high. This makes it possible to have the X-way moving up to 50 mm below center in case of milling processes or hole patterns. This corresponds to the travel of the Y-axis in both directions.
The main drive provides a torque of up to 485 Nm. The very high positioning accuracy of the C-axis is achieved by the direct travel measuring system which is part of the standard equipment.

The automation component

- In combination with the DNH bar loading magazine, which was developed by TRAUB for use with CNC turning machines, the machine can be expanded to an economical production tool with a maximum degree of automation.

- For workpiece deployment, TRAUB provides a disk rotation in the standard version, which can be loaded with 400 kg. Other systems can be designed and delivered according to your needs.

The tool drive

Tool holders for live drilling, milling or threading tools can mounted in all situations of the tool turret. The individual drive of the tool in the working position always ensures the maximum cutting performance. In conjunction with the C-axis, Y-axis or the POLYFORM software, even complex milling operations are possible.
