TNL-26K

CNC long turning machine with a maximum spindle opening of 32 mm. The machine has a modular design and up to four tools can be used simultaneously depending on the configuration level.

  • High production rates due to simultaneous machining with up to 4 tool carriers at the main and counter spindle; chip to chip time 0.55 sec.
  • Main and counter spindle with hollow shaft motors and synchronous drive technology
  • 2 tool carriers, used as multifunctional turrets with high speed indexing and 12 stations (individually or centrally driven)
  • Front attachment with 5 or 7 stations for fixed and driven tools
  • Backworking with tool drive for up to 5 tools
  • Minimal tool interference due to patented arrangement of all tool carriers in two intersecting working planes
  • Standard tooling and fast tool mounting as well as short setup times
  • Easily accessable work area from both sides
  • Compact footprint

The kinematics

The sliding headstock automatic TRAUB TNL26 is designed as a modular system. It can be suited exactly to the customers needs: a flexible turning center with two turrets for easy parts or with four tool systems for productive manufacturing of complex pieces. The decisive factor is not the multitude of variants, but the profit you make. You pay only for what you need.

View into the work area

The Z-axis on the upper tool carrier allows synchroneous machining with both turrets

The TNL26 has lots of highlights to offer. Thus, main and counter spindles have absolutely identical designs and have been constructed as liquid-cooled motor spindles in synchronous technology. Their motor powers of up to 10.7 kW are unique on the market and substantially exceed those of comparable drives. Increased power is also provided by the tool drives at 5. 5 kW. This is particularly advantageous for complete machining. Despite the highlights mentioned, the TNL26 has a very compact design and is readily accessible from both sides. The extremely fast TRAUB TX8i-s 64-bit control has the following standard features: visual control of the geometries, work sequence, collision (2D simulation) and user-oriented software for use, operation and optimization at the machine.
