Index Corporation Sliding/Fixed Headstock Automatic Lathe

Index Corporation's Traub TNL18 sliding/fixed headstock automatic lathe features seven linear axes and 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°, highly complex parts, and complicated contour elements that also require additional operations such as milling, drilling, lateral drilling, or l-threading, may be machined at any angular position.
   
Previously, for parallel main spindle operations, angled tool holders were necessary with "normal" turret positioning – now the turret simply pivots. In addition, the 8-position turret with the double driven toolholder per position capability provides additional flexibility.

Higher workpiece quality is possible by the omission of angle-adjustable tool holders, creating more stable machining conditions in the machine system.

Tool turret indexing is carried out by an NC rotary axis without a mechanical lock. This permits free angle positioning of the turret. The lathe also comes with the new Traub compact shank system, improved for high-precision mounting of tool holders in the turret.
