Why Precision Matters in CNC Machined Components?
In 2025, our team encountered a medical device project where 0.01mm tolerance decided product viability. This experience taught us that parts CNC machining isn’t just about cutting metal – it’s engineering artistry.

The 5-Step CNC Programming Protocol
- 3D Model Validation (Check wall thickness & radii)
- Toolpath Simulation
- Cutting Parameter Optimization
- Dry-run Verification
- First-Article Inspection
Warning: Never skip step 4! A 2023 NIST report shows 37% of machining errors originate from untested toolpaths.
Cost-Saving Secrets in Custom CNC Parts
Interestingly, material selection impacts costs more than machine time. For example, using 6061 aluminum instead of titanium can reduce expenses by 65% while maintaining adequate strength for most industrial applications.
FAQs: CNC Machining Essentials
- Q: How tight can machining tolerances be?
- A: Standard ±0.025mm, precision ±0.005mm
- Q: What’s the minimum order quantity?
- A: Many suppliers now offer 1-piece prototyping
