Kev lag luam khawb av yog ib qho tseem ceeb tshaj plaws hauv kev lag luam thoob ntiaj teb, yog vim li cas nws thiaj li tseem ceeb heev uas yuav tsum xyuas kom meej tias txhua yam khoom siv siv hauv kev ua haujlwm khawb av yog qhov zoo tshaj plaws. Ib qho ntawm cov khoom tseem ceeb ntawm kev ua haujlwm khawb av yog lub tshuab xa khoom. Cov tshuab xa khoom hauv qhov av khawb av thiab cov tshuab xa khoom ntsej muag yuav tsum tau saib xyuas zoo kom cov txheej txheem khawb av khiav tau zoo thiab muaj kev nyab xeeb.
Hauv kev ua haujlwm khawb av, nws yog ib qho tseem ceeb uas yuav tsum siv cov saw hlau khawb av zoo uas ruaj khov thiab tuaj yeem tiv taus cov xwm txheej hnyav.DIN22252 thiab DIN22255 cov saw hlau khawb avyog ob txoj saw hlau uas siv dav tshaj plaws hauv kev lag luam khawb av. Paub txog lawv qhov zoo, cov saw hlau no tau tsim los ua kom tau raws li cov kev cai nruj ntawm kev lag luam khawb av.
Cov saw hlau DIN22252 thiab DIN22255 muaj ntau qhov loj me, nrog rau qhov loj me 18x64, 22x86, 30x108, 38x126 thiab 42x146 yog qhov siv ntau tshaj plaws. Cov saw hlau no feem ntau yog ua los ntawm cov hlau zoo thiab muaj zog txaus los tiv taus lub zog thiab kev ntxhov siab ntawm kev ua haujlwm hauv av. Cov saw hlau kuj tseem tsim los nrog cov txuas puag ncig kho cua sov thiab tawv, ua rau nws tsis yooj yim puas thiab rhuav.
Ib qho ntawm cov kev xeem tseem ceeb uas cov saw hlau khawb av yuav tsum dhau yog qhov kev xeem lub zog tawg. Qhov kev xeem no yog siv los txiav txim siab qhov siab tshaj plaws uas cov saw hlau tuaj yeem nqa tau ua ntej nws tawg. DIN22252 thiab DIN22255 cov saw hlau khawb av yog tsim los ua kom tau raws li qhov yuav tsum tau ua kom lub zog tawg uas kev lag luam khawb av tau teeb tsa rau kev siv nyab xeeb.
Cov txheej txheem tsim khoom ntawm DIN22252 thiab DIN22255 cov saw hlau khawb av siv cov hlau sib xyaw zoo xws li 23MnNiMoCr54. Kev siv cov khoom siv zoo no ua kom cov saw hlau muaj lub neej ua haujlwm ntev thiab tsim los siv rau hauv cov xwm txheej khawb av hnyav.
Thaum xaiv cov saw hlau khawb av, yuav tsum xav txog qib ntawm cov saw hlau. DIN22252 thiab DIN22255 Cov saw hlau khawb av yog qib C, uas txhais tau tias lawv tsim nyog rau cov chaw khawb av hnyav. Kev xaiv cov saw hlau qib siab xws li DIN22252 thiab DIN22255 yog qhov tseem ceeb vim tias lawv muaj qhov ruaj khov thiab lub zog uas xav tau rau kev ua haujlwm khawb av.
Xaus lus, kev xaiv cov saw hlau khawb av zoo yog qhov tseem ceeb heev kom ntseeg tau tias kev ua haujlwm khawb av khiav tau zoo thiab ua haujlwm tau zoo. DIN22252 thiab DIN22255 cov saw hlau khawb av yog cov saw hlau khawb av siv dav tshaj plaws hauv kev lag luam thiab tau tsim los ua kom tau raws li cov kev cai nruj ntawm kev lag luam khawb av. Thaum yuav cov saw hlau khawb av, qib thiab qhov loj ntawm cov saw hlau yuav tsum tau xav txog kom ntseeg tau tias lawv tsim nyog rau kev ua haujlwm khawb av.
