Axes decoupling

To improve dynamics and rigidity and to achieve a compact configuration according to the modular concept, the motion axes of the G-modules have been divided into tool and part side.

Modular configuration

The standardized basic principle of the G-series permits a modularized manufacturing process with shorter throughput times and minimized part costs. This effectively reduces the number of assemblies while permitting a broad range of combinations.

Optimum flexibility

The G-module ensures a fast and flexible response to part modifications and to type changes. This modular principle also makes for easy reusability.

Extremely economic

The G-modules are designed for both wet and dry machining. In the system overall, they require only a very small footprint and are optimized for short throughput times. Thanks to constant further development, energy-saving measures are already offered as standard.

Completely future-proof

The G-series considers increasingly shorter innovation cycles and fast product changes. Its reduced footprint and commissioning effort makes it a flexible partner for all manufacturing tasks and any process modification.

Tilting rotary tables

Various tilting rotary table versions are available for the G720, depending on the requirement. The powerful rotary tables are based on the latest torque motor technology and offer optimized dynamics.

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 G720 and have optimized quality features.

Motorized spindle versions
  • HSK-A100, 340 Nm, 6,000 rpm
  • HSK-A100, 340 Nm, 10,000 rpm
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 the latest and most powerful CNC control systems from market leaders for the G720.
