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.

Tilting rotary tables

Various tilting rotary table versions are available for the G350, 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 G350.

Other tilting rotary table versions

We offer a highly dynamic rotary table with pallet clamping system for the highly efficient machining of large parts with short tools. Long, narrow components are machined on Vario rotary table versions as the basic module, with steady rest and tailstock center or with steady rest and tandem drive.

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 G350 and have optimized quality features.

Motorized spindle versions
  • HSK-A63, 83 Nm, 12,000 rpm (standard)
  • HSK-A63, 206 Nm, 16,000 rpm
  • HSK-A63, 47 Nm, 18,000 rpm
  • HSK-A63, 47 Nm, 21,000 rpm
  • HSK-A63, 63 Nm, 30,000 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

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.
