Stampings test methods
time2012/09/03
Touch test:
Outside the coverage of the surface with a clean gauze wipe. Inspectors should wear the touch gloves close to the surface of the stampings longitudinally along the stampings touch, this test method depends on the experience of the examiner. Whetstone grinding Discovery of suspicious areas can be used, when necessary, be verified, but this approach may well be an effective rapid test method.
Whetstone polished:
1, the first with a clean gauze to wipe the surface of the outer cover, and then grinding oil stone (20 × 20 × 100mm or larger), arc polished and hard-to-reach places with relatively small Whetstone (example: 8 × 100mm semicircular Whetstone)
Whetstone granularity selection depends on surface conditions (such as roughness, galvanized, etc.). Recommend using granular Whetstone. Whetstone grinding direction basically along the longitudinal direction, the surface lamination stampings and good, some special places can also add a horizontal grinding.
Flexible gauze polished:
Outside the coverage of the surface with a clean gauze wipe. Flexible sand network close to the surface of the stampings along the longitudinal polished to the entire surface, no pitting, indentation will easily be found.
Oiler test
Outside the coverage of the surface with a clean gauze wipe. Then clean brush evenly coated oil to the entire outer surface of the stamping member along the same direction. James finished oil stampings on the bright light test, the stampings vertical body position. This method can be easily found the stampings tiny pitting, deflated Tong, corrugated.
Visual Inspection:
Visual inspection for abnormal appearance of stampings and macro defect.
Submit a test
Stampings in the seizure, according to submit the manual operating requirements, detection of the stampings.
