If you need high-quality, precision-machined parts in brass, copper, or titanium, CNC turning and milling services are your best bet. Whether it’s for aerospace, medical devices, or industrial machinery, getting the right fit, finish, and durability matters.
Why CNC Machining for Brass, Copper & Titanium?
These metals aren’t just chosen at random—they each bring unique benefits (and challenges) to precision machining:
1. Brass – The Machinist’s Best Friend
- Easy to Machine – Cuts cleanly, minimal tool wear.
- Corrosion-Resistant – Great for marine and plumbing parts.
- Aesthetic Appeal – Polishes to a brilliant gold-like finish.
- Common Uses: Electrical connectors, valves, decorative hardware.
2. Copper – The Conductive Powerhouse
- Superb Electrical & Thermal Conductivity – Ideal for electronics and heat exchangers.
- Antimicrobial – Used in medical and food-grade applications.
- Challenge: Soft and sticky—requires sharp tools and proper chip control.
- Common Uses: Busbars, RF shielding, cooling components.
3. Titanium – The Strong, Lightweight Performer
- High Strength-to-Weight Ratio – Lighter than steel but just as tough.
- Biocompatible – Perfect for surgical implants and aerospace.
- Challenge: Harder to machine—needs specialized tooling and slower speeds.
- Common Uses: Aircraft fasteners, medical screws, high-performance automotive parts.
CNC Turning vs. Milling: Which One Do You Need?
Both processes are essential, but they serve different purposes:
1.CNC Turning (Lathe Work) – Best For:
- Cylindrical parts (rods, bushings, screws).
- High-speed production of rotationally symmetric components.
- Threading, grooving, and boring operations.
2.CNC Milling – Best For:
- Complex 3D shapes (brackets, enclosures, prototypes).
- Flat surfaces, pockets, and intricate contours.
- Multi-axis machining for advanced geometries.
Key Factors for Precision CNC Machining Success
1. Tolerances Matter (±0.01mm or Tighter?)
- Medical and aerospace parts often demand ultra-tight tolerances.
- Standard industrial parts may only need ±0.05mm.
2. Surface Finish Options
- As-Machined – Good for functional parts.
- Bead Blasting – Uniform matte texture.
- Polished – For decorative or low-friction applications.
3. Material Grades Matter
- Brass: C360 (free-machining) vs. C260 (cartridge brass).
- Copper: C101 (pure) vs. C110 (electrolytic tough pitch).
- Titanium: Grade 2 (commercial pure) vs. Grade 5 (Ti-6Al-4V).
Real-World Applications
- Brass: Precision nozzles, instrument components.
- Copper: Laser parts, semiconductor fixtures.
- Titanium: Orthopedic implants, drone frames.
