5-axis universal machining center
The G150 is the smallest universal machining center in the G-module concept of GROB and enables customers from various industries to machine with the highest precision. With direct and absolute position encoders in all axes, the 5-axis machining center guarantees maximum accuracy for complex components and features an innovative calibration and cooling concept.
Machine highlights:
The horizontal spindle position permits the longest possible Z-travel path in the machine class and optimum chip fall.
Three linear and two rotary axes permit 5-sided machining as well as 5-axis simultaneous interpolation.
The machine's unique axis arrangement permits overhead machining, offering you an optimum accessibility to the part and almost limitless possibilities for part machining.
The basis of the drive concept are two symmetrically arranged ball screws and a weight compensation function in the Y'-axis. Torque motors in the A'- and B'-axes ensure dynamic and wear-free machining of parts.
The unique arrangement of the three linear axes minimizes the distance between the guides and the machining point (TCP), lending the machine considerable stability.
The unique axis arrangement permits an extremely large swivel range of 230° in the A'-axis.
The tunnel concept allows the largest possible component – even in the case of with extremely long tools – to be machined within the work area without collision.
