4-Axis Bridge Cutting Machine – Advanced Edition
Bus absolute-value servo, 0-360° head rotation, 85° table tilting – cut, chamfer, profile and mill in one cycle
1. Machine Overview
The Expand 450 Series is a 4-axis bridge-type CNC cutting centre built for high-precision, multi-angle processing of granite, marble and engineered stone.
Bus absolute-value servo, 0-360° cutting-head rotation, 85° table tilting and oil-immersed track let you cut, chamfer, profile and mill complex shapes in a single program – mirror-quality edges.
| Feature | Benefit |
| 4-axis linkage (X-Y-Z + C) | 360° head rotation → continuous arc, column, 3-D relief |
| 85° table tilting | Convenient loading |
| Bus absolute servo | Power-off memory, zero backlash |
| Oil-immersed track | Sealed against dust, longer rail life |
| Ø350-450 mm blade | Cuts 100 mm deep in one pass, 20-40 m/min feed |




| Model | Blade Ø | Table Size | Max Block | Tilt | Head Rotate | Foot-Print | Weight |
| Expand 450 | 350-450 mm | 3.2 × 2 m | 3.2 × 2 × 0.1 m | 45° | 0-360° | 5 × 3.1 × 2.7 m | ~4 t |
| Expand 450L | same | same | same | 0-60° | same | same | same |
| Expand 450-MC | same | same | same | 45° chamfer | same | same | same |
Same 4-axis system, oil-immersed track and permanent-magnet motor for all models.
2. Four-Axis Motion & Functions
-
X-axis – bridge longitudinal (3 200 mm)
-
Y-axis – cross beam transverse (2 000 mm)
-
Z-axis – head vertical (100 mm)
-
C-axis – 0-360° head rotation (continuous arc, column, 3-D relief)
Result: true 3-D sculpture, 360° column, under-cut or chamfer without blade change.
3. Application Gallery
-
360° columns – Ø100–1 000 mm, full or barrel
-
Arc slabs – curved wall cladding, column façades
-
45° chamfers – kerb edges, tombstone borders
-
3-D reliefs – letters, numerals, Chinese characters
-
Under-cuts – sink cut-outs, shadow grooves
Materials: granite, marble, quartzite, basalt, engineered stone.
4. Workflow (1 Operator)
-
Load slab onto tilting table (vacuum or mechanical clamp)
-
Import CAD file (.dxf, .stp) or use on-screen wizard
-
Select blade speed, tilt, rotation – click START
-
Machine auto-cuts – head rotates & table tilts as programmed
-
Unload finished piece – ready for polishing or direct install
