The Traub TNL18 sliding/fixed headstock automatic lathe with seven linear axes now is available from Index with an extra B axis, expanding its applicability to particularly challenging machining tasks. With the additional B axis in the upper tool carrier, which can pivot 100 degrees, highly complex parts and complicated contour elements that also require additional operations such as milling, drilling, lateral drilling or threading may be machined at any angular position by the TNL18-7B, the company says.
 
Previously, for parallel main-spindle operations, angled toolholders were necessary with "normal" turret positioning—now the turret simply pivots. In addition, the eight-position turret with the double-driven toolholder per position capability provides additional flexibility.
 
Setting up angle-adjustable toolholders is no longer necessary; there’s no need for using expensive angle-adjustable toolholders. The omission of angle-adjustable toolholders creates more stable machining conditions in the machine system, and because of additional operations in any angle positions, highly complex workpieces can be produced more flexibly and efficiently in a single setup, the company says.
 
Tool turret indexing is carried out by an NC rotary axis without a mechanical lock. All turret stations can be equipped with fixed or live toolholders. The number of tools in the machine can be increased to as many as 54 tool stations through dual- and multi-toolholders. Also, there is less setup effort for the operator, resulting in more productive time. High-precision, fast turret indexing enables a very fast chip-to-chip time, which is closely comparable with that of a linear tool carrier.
 
The machine also comes with the Traub compact shank system--an improved system for high-precision mounting of toolholders in the turret.
 

Toolholders are seated deeper in the turret, which results in less leverage effect and, thus, higher stiffness. For live toolholders, the large shank diameter enables insertion of roller bearings with large diameters. A quick-change system permits a high precision and fast tool change without removing the toolholder. The compact shank system increases tool life and also contributes to improved surface quality.
