· 3 min read
Key takeaways
- Use compression or diamond-cut end mills.
- Control dust with water or vacuum.
- Shallow passes avoid delamination.
Tooling
Carbide diamond-cut or compression bits keep both faces clean.
Settings
Use moderate spindle speed and several shallow passes. Hold the sheet firmly with tape or vacuum.
Safety
Carbon dust is fine and conductive — protect your lungs and your electronics.
Pro tip: Cover your CNC's electronics; carbon dust can short circuits.
