G500

Modular machining center

The modular standard of the G500 machining center makes it the ideal solution for the flexible series production of automotive components such as cylinder blocks and cylinder crankcases.

With fast chip-to-chip times, ideal chip fall and horizontal machining, the G500 machine variant guarantees productive cutting in line with customers' specific requirements.

The benefits at a glance

Reduced machine width

Maximum tool length

Fast tool change

Broad range of applications

Modern machine design

Expandable tool pockets in the tool magazine

Intelligent power unit arrangement

Highly effective loading concept

Unique machine concept

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.

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.

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.
