Quality Control

CNC Turning Quality Standards

Turned parts require concentricity and surface finish precision at every stage.

CMM verification (via our group's shared metrology center)

Critical turned dimensions can be CMM-verified via our group's shared metrology center on request. Full reports included.

Surface Finish Ra

Ground and polished surfaces verified by profilometer. Ra 0.2–1.6 achievable on cylindrical surfaces.

Tolerance Compliance

ISO 2768-m tolerance standards applied. GD&T callouts confirmed on first-article inspection (FAI) on request.

Final QC

Thread gauge inspection, surface finish verification, and visual inspection before shipment.
