Ib Daim Ntawv Qhia Tag Nrho Rau Tus Kheej Drilling Screws thiab Lawv Siv
Self-drilling screws yog ua los ntawm hardened steel hlau uas tau kho kom nws hardness. Ib qho nthuav qhov tseeb yog tias txhua tus kheej-drilling screws muaj tus kheej tapping khoom vim qhov xwm ntawm lawv ua haujlwm li cas. Kab lus no yog ib qho kev qhia ua tiav rau tus kheej-drilling screws thiab lawv siv.
Self-Drilling Screws vs. Self-Tapping Screws
Qhov twg yog qhov zoo dua rau lub fastener nyob ntawm qhov tsim nyog thiab siv cov fastener. Tsis muaj dab tsi zoo dua li tus kheej-drilling ntsia hlau thaum nws los txog rau txuag lub sij hawm raws li nws tshem tawm cov kauj ruam ntawm drilling thiab tapping ua ntej installation. Txawm li cas los xij, ob leeg muaj lawv cov kev siv, nws nyob ntawm qhov koj xav siv.
Dab tsi yog cov khoom siv laum?
Lub laum taub yog txuas nrog lub qhov ntawm tus kheej-drilling ntsia hlau. Feem ntau, nws yog ua los ntawm carbon steel, uas tsis tshua ruaj khov ntawm qhov kub thiab txias.
Lub zinc txheej yog siv rau cov hlau kom tiv thaiv corrosion thiab muab lub zog ntau dua.
Qhov kub stability ntawm lub laum taub yog proportional rau lub zog thov, hardness ntawm lub workpiece, thiab lub cev muaj zog ceev.
Kub kub ruaj ntseg ntawm tus kheej-drilling screws
Thaum tus kheej-drilling ntsia hlau tho rau hauv phab ntsa lossis ib qho khoom siv thiab nkag mus rau hauv nws tus kheej, lub laum taub ua kom sov thiab sib txhuam. Qhov no tuaj yeem tswj tau los ntawm tus nqi ntawm lub zog siv thaum drilling thiab RPM ntawm lub tshuab laum.
Drilling Temperature ntawm Self-Drilling Screws
Ntau yam cuam tshuam rau qhov drilling kub, uas tuaj yeem tswj tau thaum lub sijhawm ua ntawv thov. Koj tuaj yeem tswj hwm RPM los ntawm kev tswj hwm qee lub cev muaj zog. Ua ntej, koj yuav tsum tau kuaj xyuas qhov tseeb ntawm lub cev muaj zog rau hom khoom koj tab tom drilling thiab lub taub hau ntawm tus kheej-drilling ntsia hlau.
Cov neeg feem coob nyiam siv lub zog ntxiv los thawb lub hau ntswj mus rau hauv cov khoom siv, uas yog ib qho ntawm cov yuam kev tseem ceeb ntawm cov kev ua yuam kev. Kev siv quab yuam tsuas yog ua kom cov cua sov tsim los ntawm cov ntsia hlau.
