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 component – even in the case of with extremely long tools – to be swiveled and machined within the work area without collision.

Large swivel range
Three linear and two rotary axes permit 5-sided machining, 5-axis simultaneous interpolation as well as GROB TRAORI turning. With a swivel range of 230 degrees in the A’-axis and 360 degrees in the B’-axis, these machines offer the greatest possible positioning flexibility.
