G550T
The horizontal spindle position permits the longest possible Z-travel path and optimum chip fall.
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 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.
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.
Fast tool change through an intelligent magazine to motorized spindle arrangement
For meeting the toughest cutting requirements
Almost limitless machining potentials thanks to the largest possible swivel range
Uninterrupted part machining with chip disposal by a slat band conveyor
Intrinsically stiff welded design for optimum machine rigidity

Mill-turn tables
To provide you with the best possible support for meeting the requirements of your mill-turn operations, GROB offers tables, optimized specifically for mill-turn operations, with significantly higher maximum speeds than pure universal milling machining centers.
Spindle versions
To optimize the process design of your mill-turn operations, GROB offers mill-turn motorized spindles developed specifically for this purpose.
Tool magazine
GROB tool magazine technology is set apart by fast chip-to-chip times, a smaller space requirement and optimized accessibility. Choose the right solution for you.
Machine control panel

GROB4Pilot is your powerful machine control panel. A multi-functional user interface offers the machine operator a convenient working environment. The entire production process – from the CAD model through to the NC simulation – is digitally mapped on the GROB4Pilot control itself. GROB4Pilot is available for the control systems SIEMENS 840D sl and HEIDENHAIN TNC 640.
Features:
- 3D display of parts and their clampings
- Read out of dimensions or product characteristics (PMI) on the 3D model itself
- Touch keyboard within the display
- HTML5-compliant web browser
- Custom user interfaces
- Activation of remote maintenance via switch
Advantages:
- Enhanced user comfort with simplified and intuitive machine operation
- CAD/CAM programming on the machine itself
- Access to the GROB-NET4Industry platform
- Extended applications for increased efficiency
- Paperless production facility
- Time saving by use of applications parallel to machine operation
