Inspection

Every part measured before it ships.

Wolfer performs gear-accuracy inspection — tooth profile, tooth lead and runout included — alongside CMM measurement, hardness testing and surface-quality inspection. Inspection is the last gate before a part leaves Foshan, and the only place we never compromise. Wolfer owns the inspection equipment that most contract gear shops outsource — so the inspection happens immediately after cutting / grinding, in the same building, on the same shift.

Inside the inspection center

Gear inspection center and CMM capability

The gear inspection center, CMM and in-process inspection at work — quality closed loop inside the factory.

Coordinate measuring machine
Gear inspection center at work

Standard practice: every part lot ships with an EN 10204 3.1 material certificate by default, supporting material traceability and quality audits. Dimensional and gear-inspection-center raw data are archived in-plant by lot code as the shipment-release basis.

Capabilities

Inspection equipment

PREC60 gear measuring center (Klingelnberg-type)

Single-setup check of pitch error, profile error, lead error, and runout. Class-5 verification possible on this machine alone.

CMM

Ø 0–800 mm work envelope. For gear blanks, bores, concentricity, and general dimensional verification.

Optical profile projector

Tooth-form / thread-form / chamfer / radius — quick optical verification.

Surface-roughness tester (Mitutoyo SJ-410)

Ra · Rz · Rmax · waviness — checked on every ground surface.

Hardness testers — Rockwell + Vickers + Brinell

Full coverage 20–70 HRC, plus HV / HB for niche cases.

Magnetic-particle / dye-penetrant

Available on request for crack detection on high-load parts.
