Quality Considerations

When sourcing CNC parts from China, quality varies significantly. Key factors to verify:

• Brand of machines: Fanuc, Mitsubishi, Siemens controls vs. local controls
• Measurement equipment: CMM, micrometers, and go/no-go gauges on-site
• Material sourcing: Verify they use certified materials, not scrap
• Surface finishing: In-house or outsourced plating/anodizing/painting
• Inspection reports: CMM reports with every shipment is standard

Pricing Guide

CNC machining quotes from China are typically 30-50% lower than Western shops. Expect to pay for setup ($30-80 one-time) plus per-part cost that decreases with quantity. For a simple aluminum bracket: setup $50, per part at qty 100 is $3-5, at qty 1000 drops to $1.5-3.
