Inspection Process
How We Verify Precision
Every part undergoes rigorous inspection before shipping.
CMM verification (via our group's shared metrology center)
First-article and sampling inspections use coordinate measuring machines (CMM) per AQL 2.5 sampling standards.
Surface Measurement
Roughness verified by profilometer. We can provide Ra readings for critical surfaces on request.
Dimensional Reports
Every order ships with a dimensional inspection report. Key characteristics measured and documented.
Tight Tolerance Capability
With 5-axis machining and temperature-controlled environment, we hold ±0.005mm on critical features.
Inspection Equipment
Precision measurement you can trust.
