Unique machine concept

Horizontal spindle position

The horizontal spindle position permits the longest possible Z-travel path and optimum chip fall.

Maximum stability

The unique arrangement of the three linear axes minimizes the distance between the guides and the machining point (TCP), lending the machine considerable stability.

Tunnel concept

The tunnel concept allows the largest possible component – even in the case of with extremely long tools – to be swiveled and machined within the work area without collision.

Large swivel range

Three linear and two rotary axes permit 5-sided machining, as well as 5-axis simultaneous interpolation, with a swivel range of 230 degrees in the A-axis and 360 degrees in the B-axis.

Pure technology in the smallest space

Tilting rotary tables

Various tilting rotary table versions are available for the G550, depending on the requirement. The powerful rotary tables are based on the latest torque motor technology and offer optimized dynamics.

Tilting rotary tables A-/B-axis

Choose between tilting rotary tables with T-grooves arranged in parallel (standard), as well as tilting rotary tables with pallet clamping system (option). In addition to the standard versions with an A- and B-axis, the "A-axis" (without B-axis) and "B-axis" (without A-axis) options are offered for the G550.

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 G550 and have optimized quality features.

HSK-A100, 344 Nm, 6,000 rpm

Motorized spindle with cross-feed

The GROB motorized spindle with cross-feed allows complex internal and external contours to be manufactured with controllable tools. This spindle offers convincing system rigidity, high cutting speeds for machining contours and low tool costs. There are no additional interference contours on the motorized spindle and no need for referencing.

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.

Additional tool magazine

Single disk-type tool magazine

Double disk-type tool magazine
