4.Wanda Nut Tap Compare With Other Brand
(1).Comparison of shape: Wanda nut tap has a high degree of aliquot groove.other brand made nut tap groove aliquot uneven
(2).From the wear intensity after being processedThe surface finish of Wanda nut taps is as high as μmOhter company made the nut taps on the surface of a significant grinding shock
Cutting test-1 | |||
Brand | Size | Tapping Nuts Number | Taps operating status |
Wanda | M8 | Up to 50000 threads | As Shown in photo-unusual wear and tear |
Cutting Test-2 | |||
Brand | Size | Tapping Nuts Number | Taps operating status |
Wanda | M8 | Up to 100000 threads | <span color:#1d2129;background:white;"="" style="font-family: Arial;font-size: 14px">After normal wer and tear continue to work after grinding |
Other brand | M8 | Up to 50000 threads | Taps broken |
conclusion: Wanda nuts tap the cutting work life time more than other companies 2-3 times, has reached the international advanced level.
