High performance CNC turning center
max. 80 mm | TNA400 TRAUB Drehmaschinen

The TNA400 is the all-rounder in universal turning. The high-performance main spindle with a maximum of 485 Nm torque and 80 mm bar capacity, in combination with the optional 100 mm Y-axis path, is a guarantee for powerful cutting and comprehensive machining options.

* Precise work spindle
* Dynamic, digitally coupled AC motor for maximum torque
* Short chip-to-chip times due to the 12 station disc-type turret with driven tools at each position
* More machining possibilities with C-axis, optional Y-axis, and steadyrest
* Tailstock with hydraulic rapid return on separate guideway
* Bar feeding by means of a bar loading magazine or an integrated handling system
* Has the option of being fitted out for automatic production

The kinematics
The TNA400 is characterized by a 12-station disk-type turret with VDI40 shank, a extremely high degree of collision-free working due to a turret clearance of 420 mm and an optional 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 with the tried and tested belt spindle produces 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. Besides the short taper mounting A6, TRAUB offers also the A8.
