Frequently Asked Questions
How Do Stone CNC Routers Work?
Stone CNC routers are specialized machines designed to cut, engrave, and shape hard materials like granite, marble, quartz, and slate. They use high-power spindles, durable cutting tools, and precise computer-controlled motion to automate stone fabrication processes. Here’s how they work:
- Computer-Controlled Motion (CNC): Stone CNC routers follow G-code instructions generated from CAD/CAM software. This code directs the machine’s movements along the X, Y, and Z axes to cut or engrave stone surfaces with high accuracy.
- High-Power Spindle and Diamond Tools: Unlike wood or metal CNC routers, stone CNC machines use high-torque spindles (often 5.5kW to 9.0kW or more) paired with diamond-coated tools. These bits are strong enough to grind through dense and abrasive materials without breaking or dulling quickly.
- Water Cooling and Dust Suppression: Routing stone generates high heat and dust. Most stone CNC routers use a water-cooled spindle and water jets or sprayers at the cutting point to cool the drill, suppress dust, extend tool life, and improve routing quality.
- Heavy-Duty Frame and Table: Stone CNC routers are built with rigid steel or cast-iron frames and a reinforced table to support the weight and vibration of stone slabs. Many have vacuum tables or clamps to secure the workpiece during machining.
- Toolpath Programming and Simulation: Operators use CAM software (like ArtCAM, Fusion 360, or AlphaCAM) to create toolpaths and simulate jobs before running them. This helps prevent crashes and ensures clean, accurate results.
