How to CNC Engrave on Granite, Marble, or Any Stone (with a $5 V Bit)
Engraving on stone, particularly granite, is a beautiful and enduring craft. With the right tools and techniques, you can transform your CNC machine into a powerful tool for stone engraving. This guide will provide you with comprehensive insights into the process, technical features, and types of CNC machines suitable for stone work.
Understanding CNC Stone Engraving
CNC (Computer Numerical Control) machines have revolutionized the way we work with stone. They allow for precise cuts and intricate designs that would be difficult to achieve manually. Whether you’re engraving headstones, decorative stones, or countertops, understanding the basics of CNC stone engraving is essential.
Key Takeaways
- Stone Hardness: Choose a bit that is harder than the stone. Diamond or tungsten carbide bits are best.
- Cooling System: Use water to cool down the engraving area and prevent overheating and cracking.
- Machine Rigidity: Your CNC machine should be strong and stable enough to handle the force and resistance of stone.
- Feeds and Speeds: Adjust your feed rate and spindle speed based on your stone type, bit size, and machine power.
