The Traub TNL32-11 sliding/fixed headstock automatic lathe has a headstock moving in the Z axis, an upper and identical lower turret with X, Y and Z-axes, and a counter-spindle movable in the X and Z directions. It offers a front-working attachment that sits on an additional cross-slide moving in the X and Z axes, providing the user with further, freely positionable tools and enables the use of as much as three tools, simultaneously and independently of each other. The 11-axis machine saves machining time, especially for components with a high proportion of drilling.

In addition to the two linear X and Z axes, the front-working attachment features a CNC circular axis. By the interpolation of the rotary axis with the X axis and the C axis of the main spindle, the front-working attachment can also be used in the Y direction, using an interpolated Y axis. When a drilling tool needs to be corrected to exact center, the necessary corrections can be simply performed via the CNC controller. That is helpful with small parts that react with sensitivity to even minimal offset errors.

The front-working attachment makes eight additional tool stations available. Four of them are used to mount fixed tools, the other four are for live tools.
