The benefits at a glance
Short payback period
High productivity
Modularly expandable
Round-the-clock service
Flexible applications
Best machining quality

Unique machine concept
Horizontal spindle position
The horizontal spindle position permits the longest possible Z-travel path and optimum chip fall.

Maximum stability
The unique arrangement of the three linear axes minimizes the distance between the guides and the machining point (TCP), lending the machine considerable stability.

Tunnel concept
The tunnel concept allows the largest possible part to be swiveled and machined within the work area without collision – even in the case of machining with extremely long tools.

Large swivel range
Three linear and two rotary axes permit 5-sided machining, as well as 5-axis simultaneous interpolation, with a swivel range of 230 degrees in the A'-axis and 360 degrees in the B'-axis.
