GROB G500F

G500F

Machining center for frame structure and chassis parts
With optimized chip fall, high dynamics and short chip-to-chip times, the G500F is the ideal solution for complete and highly precise 5-axis machining of frame structure parts and battery housings.
Use the space-saving machine variant for your dry, MQL or wet machining and integrate the G500F into your automated manufacturing line either as a stand-alone solution or linked to other machines.

Machine concept
Axis arrangement

The axis combination is based on the tried and proven G-series GROB machine concept with horizontal spindle position and guarantees free chip fall and optimized heat dissipation.

Modular configuration

The modular and standardized machine components guarantee the best possible GROB product quality.

Individual automation

Available with manual or automatic front loading or automatic top loading, and optionally with integrated pallet changer.

Interference diameter

Interference diameter up to 1,550 mm (with restricted A-/B-axis swivel range), up to 1,070 mm in the B-axis and 1,120 mm in the A-axis (no restriction).

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 G500F and have optimized quality features.

Motorized spindle versions
  • HSK-A63, 47 Nm, 12,000 rpm 
  • HSK-A63, 47 Nm, 18,000 rpm 
  • HSK-A63, 83 Nm, 12,000 rpm 
  • HSK-A63, 86 Nm, 17,000 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.

Tool magazine

The single-disk magazine of the G500F achieves fast chip-to-chip times, requires only a small footprint and allows optimum access.

Control systems

Choose between modern and powerful CNC control systems from market leaders for the G500F.

Automation solutions

Draw on the experience we have garnered over several decades and benefit from the automation technology we tailor to meet your needs.

2-way pallet changer system
2-way pallet changer system

Use the GROB pallet changer system to increase your productivity by retooling during machining time.

 

Pallets are interchanged between setup station and work area by means of a rotating pallet changer. A high degree of process reliability during the pallet change sequence is guaranteed by an integrated seating check system and by flushing the zero point system.

2-way pallet changer system

Benefits:

  • Loading and unloading of the parts to the machine setup station during the machining operation
  • Double pallet changer system compactly integrated into the machine
  • Optimum accessibility to the setup station
  • Fast exchange of pallets between work area and setup station
  • Integrated seating check system for the pallets
  • Wide-opening setup station doors with crane loading capability
Loading systems
Loading systems

The G500F 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.
