TRAUB TNA400

High spindle torque up to the upper speed ranges, turning length up to 1,200 mm, ergonomic design for quick set-up and simple operation: The TRAUB TNA400 universal lathe impresses with its innovative machine design and takes universal turning to a new dimension.

The rigid and vibration-damping machine bed in mineral-cast block design ensures the best results when machining complex workpieces from batch size 1.

With a high spindle torque up to the upper speed ranges, even difficult-to-cut materials can be machined reliably. A special feature of the TRAUB TNA400 is the completely redesigned, clearly structured work area for a wide range of applications.

A turning length of up to 1,200 mm allows a wide range of machining options. With the optionally available counter spindle, rear side machining can be carried out with high precision.

The ergonomic design ensures quick set-up and easy operation of the machine.

The proven INDEX iXpanel operating concept and the 18.5" touch monitor provide the operator with all relevant data for efficient production and access to networked production at all times.

Structured machine design

The TRAUB TNA400 represents a consistent further development of proven manufacturing solutions from TRAUB. Individually equipped, this new flexible universal lathe finds its place in tool and prototype construction as well as in medium and large series production. Decades of expertise are reflected in numerous design details, such as a pocket in the sheet metal panelling above the main spindle, which ensures the collision-free use of long boring bars.

TRAUB TX8i-s control system

The iXpanel operating concept opens the door to networked production. With iXpanel, all relevant information for efficient production is available to the employee at all times directly on the TNA400 universal lathe. iXpanel is already included as standard and can be customised. You can use iXpanel as you wish for your company organisation - Industry 4.0 made to measure.
