G700F

Machining center for frame structure and chassis parts

Thanks to its extra large working area, the G700F is ideal for large structural components and allows machining of parts up to a size of 1,500 x 900 mm.

Furthermore, a narrow bridge ensures the best possible accessibility to the underside of the part for optimal 6-sided machining.

Spindle versions

Besides the broad range of spindles, the motorized spindles designed and produced by GROB itself are the preferred choice for optimized process design. These are optimally matched to the G700F and have optimized quality features.

Motorized spindle versions

HSK-A63, 47 Nm, 12,000 rpm (standard)
HSK-A63, 47 Nm, 18,000 rpm (option)
HSK-A63, 83 Nm, 12,000 rpm (option)
HSK-A100, 186 Nm, 12,000 rpm (option)
HSK-A100, 340 Nm, 10,000 rpm (option)

GROB-Spindle Diagnostics (GSD)

GROB spindle diagnostics is a system that automatically monitors the condition of the motorized spindle. Benefits are a prolonged motorized spindle useful life, reduced tool wear and scheduled maintenance.

GROB Chip-in-Spindle Detection System (SiS)

This system is able to detect at an early stage tool clamping faults caused by chips between the plain surface and the spindle nose from 10 μm. So the machining process is optimized and rejects and damage are avoided.

Control systems

Choose between modern and powerful CNC control systems from market leaders for the G700F.

Automation solutions

Loading systems

The G700F is designed for efficient work area loading. All loading devices are GROB proprietary developments, and so the individual components are guaranteed to be optimally matched.

Loading systems

Top or front loading

Robots

Top loading

Cartesian linear gantry
Cartesian linear gantry with telescope

Front loading
