CNC Bridge Saw FAQ
Your comprehensive guide to CNC bridge saws for stone fabrication
In modern stone fabrication, CNC bridge saws are essential for cutting marble, granite, quartz, and sintered stone with precision and efficiency. Whether you are a beginner or an experienced fabricator, this FAQ answers common questions about operation, selection, and maintenance.
1 What Is a CNC Bridge Saw?
A CNC bridge saw is a computer-controlled cutting machine designed to process stone slabs with high precision. The bridge design allows the cutting head to travel across large slabs while software automates accurate cuts.
Ideal for both mass production and custom projects, CNC bridge saws reduce human error and increase throughput.
2 What Materials Can a CNC Bridge Saw Cut?
Common materials include:
Marble
Used for countertops, tiles, and decorative pieces. CNC cutting preserves natural veining.
Granite
Durable option for kitchen/bathroom surfaces. CNC ensures clean cuts on hard granite.
Quartz
Engineered stone for interiors. CNC enables precise custom shapes.
Sintered Stone
Modern material for flooring/wall cladding. Requires stable CNC cutting.
3 What Is the Difference Between a 4 Axis and 5 Axis CNC Bridge Saw?
- 4 Axis: Straight and angle cutting, profiling and shaping. Great for countertops and standard fabrication.
- 4+1 Axis: Adds a rotational axis for mitre and compound-angle cuts—good balance of cost and capability.
- 5 Axis: Full 3D machining for complex shapes and curved surfaces—used for advanced projects.
4 How Accurate Are CNC Bridge Saws?
CNC bridge saws typically achieve millimeter-level accuracy (often ±0.1–0.3mm) depending on machine class and calibration.
Proper fixturing, calibration and maintenance are essential to keep accuracy over time.

5 What Software Do CNC Bridge Saws Use?
Common choices:
- Stone-focused CAM (TopSolid Stone, AlphaCAM Stone)
- General CAD/CAM (AutoCAD, Fusion 360 with stone plugins)
6 How Much Maintenance Does a CNC Bridge Saw Require?
Typical weekly checks (1–2 hours):
Check Water Cooling
Prevent overheating
Inspect Blades/Spindles
Ensure sharpness
Clean Dust Filters
Maintain air quality
Calibrate Axes
Preserve precision
7 Can CNC Bridge Saws Cut Sintered Stone?
Yes. Sintered stone needs stable, low-vibration cutting; advanced machines use high-torque spindles, damping structures and blades specialized for sintered materials.
- High-torque spindles
- Vibration damping
- Specialized blades
8 What Are the Benefits of Using a CNC Bridge Saw?
High Precision
Millimeter-level cuts reduce waste and ensure consistency.
Faster Production
Automation reduces project time significantly.
Reduced Waste
Precise toolpaths minimize scrap.
Complex Shapes
5-axis models enable advanced 3D designs.
