What Dictates Your CNC Milling Deadline?
| Factor | Speed Impact (+/-) | Real-World Example |
| Part Complexity | High | Simple bracket: 1-3 days 5-axis aerospace impeller: 2-4 weeks |
| Material | Medium | Aluminum (6061): Fastest Titanium/Stainless: +50% time |
| Quantity | Low | 1-10 pcs: Days 1000+ pcs: Weeks (but cost/part drops!) |
| Post-Processing | High | Anodizing/+3 days Heat treat/+1 week |
| Shop Workload | Medium | "Rush tax": 30-100% surcharge |
3 Insider Hacks to Slash Lead Times
Design Smart = Machine Fast
- Avoid deep pockets & thin walls → chatter = slower feeds.
- Use standard tool radii (e.g., 3mm end mills ≠ , exotic sizes).
- > Protip: Run a DFM check before sending files!
Material Matters More Than You Think
"Aluminum 6061 machines 4x faster than stainless 304. Choose wisely!"
- Speed Kings: Aluminum, Brass (C360)
- Slowpokes: Tool steels, Inconel
Partner Like a Pro
- Ask upfront: "Do you keep 6061/Alum stock?" → Saves 2-5 days.
- Batch orders: Combine parts → 1 setup = lower cost/time.
