Quality Control

Forging dimension testing:
Inspectors are inspecting forging dimensions in 100% to ensure subsequent machining process.

 
 
UT for forgings:
Inspector is doing forgings incoming inspection:(ultrasonic testing) to ensure the forgings without defect.
 
Traceability card:
 Mark identification forging number and make traceability card to ensure all forgings controlled and traceable.
 
 
Teeth hardening depth testing:
Inspector is testing the teeth hardening depth by use of hardening layer thickness gauge.
 
 
Hardness testing:
Inspector is testing the raceway hardness by hardness tester.
 
Surface roughness testing:
Teeth surface roughness gauge can test bearing teeth surface roughness with high precision.
