• Outstanding technology in a confined space The G350 machining center is characterized by its compact, rigid design with optimal machine accessibility to the work area.

• Horizontal spindle The machine design with its unique axis configuration allows optimal chip flow. Compared with similar machines, the G350 has the longest z axis stroke. The horizontal spindle orientation provides the machine with the highest stability.

• Base • The machine base as well as most of the supporting

components are made of heavy rigid welded constructions.

• The Y axis slide, the rotary table housing and the spindle housing are cast iron constructions.

• The machine is placed and adjusted on three leveling elements. Two more leveling elements provide the machine with additional stability.

• Axis control The 3 linear and 2 rotary axes allow 5-side machining as well as 5-axis simultaneous interpolation.

The machine allows a maximum axis rotation of: 240º in the a axis, 360º in the B axis

• Modern GROB technology As in all GROB machining centers, the G350 is a highly dynamic machine with the highest rigidity.

• Optimal flexibility The G350 is a universal machining center that can be configured to your required application.

• Controls The G350 uses convenient and user-friendly controls of the newest generation: • Siemens 840D sl • Heidenhain iTNC 530 • FANUC 31i • BOSCH MTX

• High efficiency The G350 has been designed, as all machines of the G-Series, for optimum wet and dry machining. The compact machine design requires only a small footprint.

• Optional automation There is a pallet changer and/or a pallet storage options available for automatic workpiece exchanges. The tool magazine can be extended to 133 or 205 holders.

• Service GROB G350 customers have 24/7 access to our worldwide service group.

• Hydraulic free machine Due to substituting of all hydraulic components with electromechanical components the machine operates hydraulic free. You have the choice – the G350 also available with hydraulics.

You have a part with the following requirements: • 5-side machining• Multi-angled holes and surfaces• Forms and profiles• Precision parts

We have the solution: The G350 – the 5-axis universal machining center from GROB.
