Muaj ob series ntawm A thiab B hauv tus lej saw. A series yog qhov loj me uas ua raws li tus qauv saw Asmeskas: B series yog qhov loj me uas ua tau raws li tus qauv saw European (feem ntau yog UK). Tsuas yog tib lub suab xwb, lawv muaj lawv tus kheej cov yam ntxwv hauv lwm yam. Qhov sib txawv tseem ceeb yog:
1) Lub thickness ntawm lub phaj sab hauv thiab lub phaj sab nraud ntawm cov khoom A series yog sib npaug, thiab qhov sib npaug zog ntawm lub zog zoo li qub tau txais los ntawm kev hloov kho sib txawv. Lub phaj sab hauv thiab lub phaj sab nraud ntawm cov khoom B series tau hloov kho kom sib npaug, thiab qhov sib npaug zog ntawm lub zog zoo li qub tau txais los ntawm Baidu sib txawv.
2) Qhov loj me ntawm txhua qhov ntawm A series muaj qee qhov sib piv rau qhov suab. Xws li: lub taub hau pin = (5/16) P, lub taub hau roller = (5/8) P, lub phaj saw hlau tuab = (1/8) P (P yog lub suab saw hlau), thiab lwm yam. Txawm li cas los xij, tsis muaj qhov sib piv pom tseeb ntawm qhov loj me thiab suab ntawm B series qhov chaw.
3) Piv rau qhov tawg ntawm cov saw hlau ntawm tib qib, tsuas yog tias 12B qhov tshwj xeeb ntawm B series qis dua li ntawm A series, lwm cov lus qhia zoo ib yam li cov khoom A series ntawm tib qib.
Tus qauv khoom lag luam yog sib npaug rau tus qauv thoob ntiaj teb ISO9606: 1994, thiab nws cov khoom lag luam, qhov loj me thiab tus nqi tensile load yog sib xws nrog tus qauv thoob ntiaj teb.
Cov yam ntxwv ntawm cov qauv: Cov saw hlau yog tsim los ntawm cov phaj sab hauv, cov menyuam thiab cov tes tsho, uas tau hloov pauv nrog cov txuas sab nraud, uas yog tsim los ntawm cov phaj sab nraud thiab cov ncej pin.
Rau kev xaiv khoom, cov lus qhia tshwj xeeb ntawm cov saw hlau yuav tsum tau xaiv raws li cov kab hluav taws xob. Yog tias xaiv raws li kev xam, qhov kev nyab xeeb yuav tsum ntau dua 3.
