Ukuqonda Umehluko Phakathi Kwama-self-tapping kanye nezikulufi ezijwayelekile

1. Izinhlobo zochungechunge: Mechanical vs. Self-Tapping
Izikulufu ziza ngezinhlobo ezimbili zochungechunge oluyinhloko: okomshini nokuzithepha.Amazinyo emishini, avame ukufushaniswa ngokuthi “M” embonini, asetshenziselwa ukuthepha amantongomane noma izintambo zangaphakathi.Ngokujwayelekile iqonde ngomsila oyisicaba, inhloso yabo eyinhloko ukubopha insimbi noma izingxenye zomshini wokuvikela.Ngakolunye uhlangothi, izikulufu ezizithephayo zifaka amazinyo angunxantathu noma awunxantathu oyindilinga oyindilinga.Ezaziwa njengezikulufu ezizikhiyayo, idizayini yazo yochungechunge ethuthukisiwe ivumela ukungena kalula ngaphandle kokudinga imbobo ebhojwe ngaphambili.

2. Idizayini Yekhanda kanye Nomehluko Wephrofayili
Umehluko ogqame kakhulu phakathi kwezikulufu ezizithephayo nezikulufi ezijwayelekile usekuklameni kwazo kwekhanda kanye nephrofayili yomucu.Izikulufu ezijwayelekile zinekhanda eliyisicaba, kuyilapho izikulufo ezizithephayo zifaka ikhanda elicijile.Ukwengeza, ububanzi bezikulufu ezizishayayo bushintsha kancane kancane ukusuka ekugcineni ukuya endaweni evamile yobubanzi, kuyilapho izikulufi ezijwayelekile zigcina ububanzi obungaguquki, ngokuvamile ziba ne-chamfer encane ekugcineni.

Ngaphezu kwalokho, i-engeli yephrofayili yezinyo idlala indima ebalulekile.Izikulufu ezijwayelekile zine-engeli yephrofayela yezinyo engu-60°, enikeza amandla okubamba amangalisayo nokuzinza.Ngokuphambene, izikulufu ezizithephayo zine-engeli yephrofayela yezinyo engaphansi kuka-60°, okuzivumela ukuthi zikhiqize imicu yazo njengoba zingena ezintweni ezifana nokhuni, ipulasitiki, noma izinsimbi ezincane.

3. Ukusebenziseka Nokucatshangelwa Kokusetshenziswa
Umehluko phakathi kwezikulufu ezizithephayo nezikulufi ezijwayelekile zinquma izinhlelo zazo eziqondile kanye nokucatshangelwa kokusetshenziswa.Izikulufu ezijwayelekile zivame ukusetshenziswa ezimeni lapho ukuqondanisa okunembayo nokuzinza kubalulekile, njengokuhlanganisa amadivaysi kagesi athambile noma ukuvikela izingxenye zemishini.

Izikulufu zokuzishaya, ngakolunye uhlangothi, zenzelwe ngokukhethekile ukudala imicu yazo yokukhwelana njengoba ishayelwa ezintweni ezithambile, ezisusa isidingo sezimbobo ezimbozwe ngaphambili.Basetshenziswa kakhulu emisebenzini yokwenza ngokhuni, ukunamathisela izinto odongeni olomisiwe, ukuhlanganisa ifenisha, nokufaka izinsimbi zokufulela.

Kubalulekile ukuqaphela ukuthi izikulufi zokuzithepha zingase zingalungeli zonke izinhlelo zokusebenza.Uma usebenza ngezinto eziqinile njengensimbi engagqwali noma ama-alloys, izimbobo ezimbozwe ngaphambilini ngokuvamile ziyadingeka ukuze kuqinisekiswe ukufakwa ngempumelelo ngaphandle kokulimaza isikulufu noma into.
