UGMIC's thread technology consultant recommends that the "core problem-solving approach" should be established as follows : 

Problem symptoms → Check working conditions → Judgment → Threading tool selection → Threading tool parameter optimization → Verification

rather than jumping directly from the "problem" to "tool replacement" and other trial-and-error methods.

UGMIC is a high-quality manufacturer providing (thread tool selection × thread tool parameter optimization).

5.1 Common thread problems

Mainly includes :

Thread quality issues

• Abnormal thread dimensions

•  Thread size accuracy fluctuates

•  Insufficient thread precision

•  Incomplete thread profile

•  Rough thread surface

•  Thread surface scratches

•  Thread exit burrs

•  Thread breakage at the outlet

•  Thread outlet tooth deformation

•  Unstable quality of thread outlet

•  Insufficient tap life (thread gauge failure)
•  Tap wears out quickly (inspection failure)
•  Silk tapping blade breakage
•  Tap thread wear
•  Tap chip entanglement
•  Tap chip clogging
•  Tap chips get stuck
•  Tap chips sticking
•  Poor chip removal in blind holes from taps
•  Tap chips scratch the threads
•  Chips adhere to the end of the tap thread

•  Thread gauge detected abnormality
•  Go gauge failure = unable to proceed to the end
•  Go gauge failure = can only enter 2-3 turns
•  NoGo gauge failure = can enter 2-3 turns
•  NoGo gauge failure = Can go all the way through
•  Go gauge and NoGo gauge failure
•  Difficulty in coordination
•  Threaded assembly failure
•  Thread torque test fracture
•  Thread tensile test fracture
•  Cracks in threaded ammonia fumigation test
•  Threaded dry seal test for air leakage
•  Threaded dry seal test for leaks
•  High-pressure test for leaks during thread assembly
