The Traub TNL and TNL-K machine series offers both fixed and sliding headstock designs on the same machine platform for small turned parts. Four machines are available in this series. TNL offers long/sliding headstock Swiss-type turning, and TNL-K offers fixed headstock screw machine-type turning. The machines are available in two model sizes and both models are based on a building block concept, allowing the user to configure the machine exactly to his requirements.

The TNL12 is available with two six-station turrets (Y axis on one turret), a four-station endworking tool carrier, a counterspindle and a four-station back working tool carrier (y axis optional). The maximum Z-axis travel is 7" on the L version and 2" on the K version. The maximum number of fixed tools is 26, 18 of which can be live tools.

The TNL26 is available with two 12-station turrets (Y axis is optional on both turrets), a five-station endworking tool carrier, a counter spindle and a five-station back working tool carrier. The maximum Z-axis travel is 10" on the L version and 4" on the K version. Also, the maximum number of fixed tools is 58 and 32 of these can be live tools.

The company’s turret tool carrier concept offers a higher tool capacity in the machine. Since one live tool can be mounted in each turret station, then the total number of live tools is much higher. The high speed indexing system causes chips to be thrown away from the tools.

Both the main and the counterspindle offer the same high horsepower. The TNL12 has up to 4.0 Kw/5.2 hp and up to 10.7 kW/14.6 hp on the TNL26. Live tools go up to 1.5 Kw/2 hp on the TNL12 and 5.5 Kw/8 hp on the TNL26.
