# GROB G350

Hardware · `G350` · verification: source checked

The GROB G350 is a 5-axis universal machining center with three linear axes (X/Y/Z) and two rotary axes (A/B) for 5-sided machining and 5-axis simultaneous interpolation. Working travels are 600 mm in X, 855 mm in Y and 750 mm in Z, with a 570 mm diameter tilting rotary table and an HSK-A63 motorized spindle. It is intended for milling parts in aerospace, mechanical engineering, automotive, energy, medical, and die and mold work.

## Study notes

- Linear travels: X 600 mm, Y 855 mm, Z 750 mm.
- Maximum axis speeds: 70 m/min (X), 45 m/min (Y), 90 m/min (Z).
- Positioning accuracy in X/Y/Z is 0.006 mm.
- Chip-to-chip time t1 is 2.7 s according to VDI 2852, relative to spindle speed.
- Interference diameter is 720 mm.
- Table diameter is 570 mm; maximum table load is 400 kg without pallet and 340 kg with pallet.
- Total machine weight is 15,300 kg without pallet changer and 17,500 kg with pallet changer.
- Swivel range is 230 degrees in the A-axis and 360 degrees in the B-axis.
- Motorized spindle versions: HSK-A63 83 Nm at 12,000 rpm (standard), 206 Nm at 16,000 rpm, 47 Nm at 18,000 rpm, 47 Nm at 21,000 rpm, and 63 Nm at 30,000 rpm.
- Tool magazine options are single disk-type and double disk-type; maximum tool length is 365 mm for the single disk magazine and 365/180/550 mm for the double disk magazine (bottom/top/over both disks), HSK-A63.
- The horizontal spindle position is used to obtain a long Z travel and chip fall; the tunnel concept allows large components and long tools to be swivelled and machined in the work area.
- The GROB4Pilot machine control panel is available for the SIEMENS 840D sl and HEIDENHAIN TNC 640 control systems, which are not in the reference controller list.
