68% of CNC parts failures trace back to improper material choice. Fun fact: 6061 aluminum costs 30% less than 7075 but fails 4× faster in high-stress applications (ASM International, 2025). Our team salvaged a $25k aerospace order by switching to titanium-grade 5 mid-production.
Standard | Cost Impact | Application |
---|---|---|
±0.001″ | +$18/part | Medical devices |
±0.005″ | Base price | Automotive |
Never accept “mill-certified” materials without cross-checking. GD Weiting found 12% material certificate discrepancies in 2024 batches.
A leading CNC machining parts manufacturer reduced cycle time 35% using trochoidal milling. Counterintuitive: They increased feed rate 22% while decreasing RPM 15%.
Q: How to identify overpriced CNC parts?
A: Compare cost per cubic inch: $0.18-0.35 is typical for aluminum.
Q: Best surface treatment for food-grade parts?
A: Electropolishing outperforms anodizing by 7× in corrosion resistance.
