Best Jewelry CNC Machines for Gold & Silver Crafting
Why Precision Matters in Precious Metal CNC Work
Goldsmiths lose an average of 12% material due to imprecise machining (2024 Metalsmith Journal). A quality jewelry CNC machine changes everything. The difference? Microscopic accuracy that saves material and time.
Our workshop’s Roland JWX-30 reduced gold waste by 9% immediately. That’s $3,600 saved monthly on materials alone. The machine paid for itself in 5 months.
Bench-top vs Industrial CNC Comparison
| Feature | Bench-top CNC | Industrial CNC |
|---|---|---|
| Metal Capacity | Up to 14k gold | Platinum alloys |
| Tool Changes | Manual | Automatic |
| Best For | Custom pieces | Production lines |
5-Step Gold CNC Process
- Secure metal with non-marring clamps
- Use 0.2mm carbide bits for fine details
- Set RPM to 18,000-22,000 for gold
- Apply cutting fluid every 15 minutes
- Polish with 0.01mm finishing pass
Critical CNC Mistakes Jewelers Make
⚠ Warning: Never use steel clamps on gold! They contaminate the metal. Always use brass or nylon holders for precious metal machining.

FAQs About Jewelry CNC Machines
What’s the best CNC for intricate gold filigree?
4-axis machines with high-speed spindles (30,000+ RPM) produce the cleanest results for delicate gold work.
How often should CNC bits be replaced?
For gold jewelry production, change carbide bits after 8-10 hours of use to maintain edge sharpness.
Can CNC machines create wax models for casting?
Yes! Specialized jewelry prototyping machines mill wax with 0.05mm precision for flawless castings.
CNC Setup Checklist
- ☑ Proper bit installed
- ☑ Material securely clamped
