TNA400
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.
View into the work area
The TNA400 is equipped with the user-friendly TX8i control system. A decisive and thus very significant advantage offered by the TX8i is the possibility of interactive programming – in dialog as well as on NC basis. This means that programming, optimization or a 2D simulation can either be made in dialog or on NC basis.
On his way to the first good workpiece, the user is guided by the control system with graphical, object-oriented dialogs, which minimizes the possibility of errors occurring and leads to a significant reduction of setup times.
Once the processes are running, the required safety is provided by a very sensitive tool breakage and tear monitoring system on the basis of current measurements on the axis motors. This monitoring is integrated into the control system. When several tools are working, each of them can be monitored simultaneously.
The TX8i control is compatible with all previous TRAUB control systems.
