11-axis automatic lathe

The Traub TNL32-11 sliding/fixed automatic lathe headstock moves in the Z-axis, with identical upper and lower X-, Y-, and Z-axis turrets. A counter spindle is movable in the X- and Z-directions. A front working attachment sits on an additional cross-slide moving in the X- and Z-axis, providing freely positionable tools and enabling simultaneous and independent use of up to three tools – saving machining time for components with a high proportion of drilling.

To eliminate offset errors, the front working attachment features a CNC circular axis. By interpolating the rotary axis with the X- and C-axis of the main spindle, the front working attachment also can be used in the Y-direction to allow centering a drilling tool via the CNC controller for small parts that cannot tolerate offset errors.

A workpiece gripper station can unload a workpiece from the counter spindle while the next part can be machined with two tools at the main spindle. The headstock’s Z-travel lets the machine be used for sliding or fixed headstock turning in less than 15 minutes.

Tool turret indexing is performed using a NC rotary axis that controls movement via an internally meshing planetary gear. The turret can be indexed to any position without requiring a mechanical locking mechanism.

Two drive trains integrated within one turret reduces non-machining time. While one tool is in use, the tool for the next work step can be accelerated to the desired speed and is available at full speed after turret indexing.
