Expand 450 / 450L / 450-MC 4-Axis Bridge Cutting Machine – Advanced Edition
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
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.

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.
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.
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
