The benefits at a glance

High productivity

Optimized availability

High visibility

Flexible applications

Maintainable

Compact design

Optimized access

Round-the-clock service

Unique machine concept

Horizontal spindle position

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

Axis arrangement

Three linear and two rotary axes permit 5-sided machining as well as 5-axis simultaneous interpolation.

Overhead machining

The machine's unique axis arrangement permits overhead machining, offering you an optimum accessibility to the part and almost limitless possibilities for part machining.

Drive concept

The basis of the drive concept are two symmetrically arranged ball screws and a weight compensation function in the Y-axis. Torque motors in the A- and B-axes ensure dynamic and wear-free machining of parts.

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.

Large swivel range

The unique axis arrangement permits an extremely large swivel range of 230° in the A-axis.

Tunnel concept

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

Tilting rotary tables

Various tilting rotary table versions are available for the G150, 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 G150.

Compact rotary table versions

An optimum swivel range is achieved thanks to the compact designs of the compact rotary table and the motorized spindle contour. Consequently, it is possible to use significantly shorter tools with smaller Z-travel paths for greater stability, accuracy and more efficient part machining.

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.

Motorized spindle versions

HSK-E40, 17,4 Nm, 42,000 rpm
HSK-A63, 82,8 Nm, 12,000 rpm
HSK-A63, 206 Nm, 16,000 rpm
HSK-A63, 46,6 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.
