Unique press concept

Horizontal spindle position
The horizontal spindle position allows the longest Z-travel in this machine class as well as optimum chip fall.

Axis arrangement
Three linear and two rotary axes enable 5-sided machining and 5-axis simultaneous interpolation.

Overhead machining
The unique axis arrangement of the machine enables, among other things, overhead machining for optimum accessibility to the workpiece as well as almost unlimited possibilities in workpiece machining.

Drive concept
The drive concept is based on two symmetrically arranged ball screws and weight compensation in the Y'-axis. Torque motors in the A 'and B' axes ensure that the workpieces are machined without wear.

Maximum stability
The arrangement of the three linear axes results in a small distance between the guides and the working point (TCP) and a particularly high rigidity of the machine.

Large swivel range
The unique axis arrangement enables an extremely large swivel range of 230 ° in the A'-axis.

Tunnel concept
The tunnel concept enables the largest possible component to be machined without collision even with the longest tools within the work area in any axis setting.
