Cov neeg siv khoom Turkish uas yuav pebCNC yeeb nkab threading tshuab dhostsis tuaj yeem ua tiav lawv cov kev xav tau rau kev kho xov tooj vim lawv xaiv Fanuc 5 pob CNC system.Yog li ntawd, nws tau txiav txim siab los hloov qhov system dua, uas ua rau kev ua haujlwm tsis yooj yim rau cov neeg siv khoom.Kev ua ntawm ntau yam threads yog kiag li nyob ntawmCNC tshuab cuab yeej, thiab kev xaiv ntawm CNC system kuj tseem ceeb tshwj xeeb.
Muaj pes tsawg hom threads muaj?
NPT yog lub npe luv ntawm National (American)Cov yeeb nkab xov, uas belongs rau American standard 60 -degree tapered yeeb nkab xov thiab yog siv nyob rau hauv North America.Cov qauv hauv tebchaws tuaj yeem pom nyob rau hauv lub teb chaws tus qauv GB / T12716-1991.
PT yog lub npe luv ntawm Pipe Thread.Nws yog 55-degree kaw tapered yeeb nkab xov.Nws belongs rau Wyeth xov tsev neeg thiab feem ntau yog siv nyob rau hauv cov teb chaws Europe thiab lub tebchaws United Nations.Feem ntau siv hauv dej thiab rojkev lag luam yeeb nkab, lub taper yog teev li 1:16.Cov qauv hauv tebchaws tuaj yeem pom hauv GB / T7306-2000.
G yog 55-degree tsis-xov sealing yeeb nkab xov, uas belongs rau Wyeth xov tsev neeg.Lub cim G sawv cev rau cylindrical xov.Cov qauv hauv tebchaws tuaj yeem pom hauv GB / T7307-2001.
Tsis tas li ntawd, 1/4, 1/2, 1/8 cov cim hauv xov xa mus rau txoj kab uas hla ntawm cov xov loj, thiab chav tsev yog nti.Cov neeg sab hauv feem ntau siv cov ntsiab lus xa mus rau cov xov loj, ib nti sib npaug 8 ntsiab lus, 1/4 nti sib npaug 2 ntsiab lus, thiab lwm yam.G yog lub npe dav dav ntawmcev xov(Guan).Kev faib tawm ntawm 55 thiab 60 degrees yog kev ua haujlwm, feem ntau hu ua yeeb nkab voj voog.Ntawd yog, cov xov yog ua tiav los ntawm cylindrical nto.
ZG feem ntau hu uacev con, uas yog, cov xov yog tiav los ntawm ib tug conical nto.Cov dej dav davlub cev sib txuaszoo li no.Lub teb chaws tus qauv yog cim raws li Rc metric xov los qhia nrog lub suab, thiab cov xov American thiab British tau qhia los ntawm cov xov tooj ntawm ib nti.Nws yog qhov sib txawv loj tshaj ntawm lawv.Metric xov yog 60 degree sib npaug profile, British xov yog isosceles 55 degree profile, thiab American xov yog 60 degrees.
Metric units yog siv rau metric threads, thiab imperial units yog siv rau US thiab British threads.
