TNA300 universal turning machine – production optimization included

The machine with demand-based adjustment for every production task


Machine highlights

Your benefits

  • Linear Y-axis with 70 mm travel

  • Tailstock on separate guideway, with hydraulic quick retraction for automatic operation

  • Dynamic, digitally coupled three-phase AC motor for maximum torque – without thermal influence on the headstock

  • Short chip-to-chip time through 12-station disk turret with individual tool drive at all stations

  • More machining options in conjunction with the C, Y-axis and optional steady rest

  • Material supply by means of bar loading magazine or integrated handling system


TNA300 in focus


The 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 TNA300 has all this as standard.


The machine design

Basic structure

The TNA300 has a torsionally and flexurally rigid inclined machine bed that is inclined at 40 degrees. It bears the thermo-symmetrically designed headstock, the profile rail rolling guide for the compound slide and the separate sliding guide for the tailstock and the steady rest. The tailstock has a hydraulic quick retraction feature with large travel and hydraulic clamping.

The work spindle

The work spindle runs in high precision, life-lubricated and play-free preloaded rolling bearings. The spindle head with short taper mounting is suitable for installing all common clamping devices.

The disk turret

The disk turret is equipped with 12 tool mountings according to DIN 69880-30. Internal coolant supply and orientation logic are of course included. It does not lift off when indexing, resulting in excellent chip-to-chip times.
