Vertical-Horizontal Conversion

One of the defining features of the GMCu/t Series is the ability to combine vertical and horizontal machining within the same machine platform.

This provides access to:

• Top faces

• Side faces

• Angular features

• Internal features

• Complex hole systems

• Curved surfaces


The machine can therefore reduce the number of separate setups required for complex components.


45° Tilting Swing Head

The standard configuration uses a:

• 45° tilting swing head

with:

• B-axis travel from -30° to +185°

• Continuous C-axis rotation

The head provides substantial angular access around the workpiece and supports both vertical and horizontal machining orientations.


B-Axis Performance

The standard 45° head provides:

• B-axis drive torque: 2500 Nm

• B-axis clamping torque: 5500 Nm

This provides substantial rigidity for:

• Five-axis milling

• Angular drilling

• Boring

• Heavy positioning work

• Complex multi-face machining


High-Capacity Rotary Worktable

The rotary worktable forms an important part of the GMCu/t concept.

Across the series:

• Worktable diameter:
Ø1000–Ø2000 mm

• Workpiece load:
1500–8000 kg

• C-axis milling torque:
2900–10,000 Nm

• Worktable clamping torque:
5500–15,000 Nm


As machine size increases, both workpiece capacity and C-axis torque increase substantially.


Optional Turn-Milling Configuration

Selected GMCu/t machines can be configured for turn-milling applications.

The turn-milling version may use:

• HSK-T100 spindle interface

• Turn-milling worktable

• Matching turn-milling spindle/head configuration

This can allow selected rotary components to combine:

• Turning

• Milling

• Drilling

• Boring

• Five-axis machining

in one machine setup.

Final turn-milling capability should be confirmed against the selected model and workpiece.


Single-Column Structure – GMC100u/t / GMC125u/t / GMC150u/t
