Inspection

Every part measured before it ships. PREC60 gear measuring center, CMM, hardness, surface.

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 gear lot ships with a one-page dimensional summary plus the raw inspection-center output. For high-precision customers (medical, semiconductor), we ship the full CMM trace plus the gear-inspection report. EN 10204 3.1 material certificates ship by default on every part lot.

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.
