Cov saw hlau yog ib feem tseem ceeb ntawm ntau yam kev siv hauv kev lag luam xws li cov tshuab xa hluav taws xob mus rau cov khoom siv thauj khoom. Ntawm ntau hom sib txawv muaj nyob hauv kev ua lag luam, Hom A thiab Hom B saw hlau yog cov siv ntau tshaj plaws. Txawm hais tias lawv zoo li zoo sib xws thaum xub thawj siab, muaj qhov sib txawv loj ntawm ob qho no. Hauv tsab blog no, peb yuav tshawb nrhiav cov yam ntxwv sib txawv thiab kev siv ntawm Hom A thiab Hom B saw hlau, qhia meej tias cov saw hlau twg zoo tshaj plaws rau cov kev xav tau tshwj xeeb.
Hom A cov saw hlau:
Cov saw hlau hom A feem ntau paub txog lawv qhov yooj yim thiab tsim qauv sib npaug. Hom saw hlau no muaj cov menyuam sib npaug zos. Cov menyuam xa hluav taws xob tau zoo thiab txo qhov kev sib txhuam thaum lub sijhawm ua haujlwm. Ua tsaug rau nws txoj kev tsim qauv sib npaug, A-saw hlau tuaj yeem xa hluav taws xob mus rau ob qho kev taw qhia, muab kev ywj pheej thiab yooj yim.
Hais txog kev siv, A-chains siv dav hauv cov tshuab xa khoom, cov khoom siv tuav khoom thiab cov tshuab tsim khoom. Vim nws muaj ntau yam ua tau, A-chains yog qhov tsim nyog rau cov chaw uas muaj cov khoom thauj nruab nrab thiab qhov ceev. Thaum saib xyuas kom zoo, cov saw hlau no muaj kev ruaj khov thiab kev ntseeg tau zoo, ua rau lawv yog qhov kev xaiv nrov thoob plaws ntau yam lag luam.
Hom B cov saw hlau:
Tsis zoo li Hom A saw hlau, Hom B roller saw hlau tau tsim los nrog cov yam ntxwv ntxiv los txhim kho lawv cov kev ua tau zoo hauv cov ntawv thov uas xav tau ntau. Hom B saw hlau muaj cov phaj txuas ntev dua me ntsis, uas ua rau lawv tiv taus cov khoom hnyav thiab kev kub ceev dua. Lub zog ntxiv no yog qhov tshwj xeeb tshaj yog rau cov ntawv thov uas cuam tshuam nrog kev thauj cov khoom hnyav lossis cov khoom siv uas muaj inertia siab.
Cov saw hlau hom B tej zaum yuav txawv me ntsis ntawm cov saw hlau hom A, nrog rau cov saw hlau qub muaj lub suab loj dua lossis lub taub hau loj dua. Cov kev hloov pauv no tso cai rau cov saw hlau B kom tiv taus cov kev ntxhov siab los ntawm cov khoom hnyav dua thiab muab kev ruaj khov ntxiv.
Cov saw hlau hom B siv dav hauv cov tshuab thiab cov khoom siv ua haujlwm hauv cov xwm txheej hnyav xws li kev khawb av, kev tsim kho thiab kev lag luam tuav cov khoom hnyav. Kev tsim qauv ruaj khov ntawm cov saw hlau hom B thiab lawv lub peev xwm los tiv taus qhov chaw ua haujlwm hnyav ua rau lawv tseem ceeb rau kev ua haujlwm zoo ntawm cov tshuab hnyav.
Txawm hais tias Hom A thiab Hom B cov saw hlau yuav zoo sib xws, lawv tau tsim txawv kom ua tau raws li cov kev xav tau ntawm daim ntawv thov sib txawv. Cov saw hlau A-ncej yog qhov siv tau ntau yam, txhim khu kev qha, thiab haum rau cov khoom thauj nruab nrab thiab qhov ceev. Ntawm qhov tod tes, B-chains muab qhov tseem ceeb rau lub zog thiab kev ruaj khov, ua rau lawv zoo tagnrho rau cov ntawv thov hnyav uas muaj cov khoom thauj siab thiab qhov ceev.
Txawm koj tab tom tsim ib lub tshuab tshiab lossis nrhiav kev hloov koj cov saw hlau uas twb muaj lawm, kev txiav txim siab hom kom raug yog qhov tseem ceeb rau kev ua tiav qhov zoo tshaj plaws. Los ntawm kev nkag siab txog cov yam ntxwv tshwj xeeb thiab kev siv ntawm Hom A thiab Hom B saw hlau, koj tuaj yeem txiav txim siab tau zoo kom ua tau raws li koj cov kev xav tau tshwj xeeb.
Nco ntsoov tias kev saib xyuas thiab kev siv roj tsis tu ncua ua lub luag haujlwm tseem ceeb hauv kev ua kom koj lub saw hlau siv tau ntev thiab ua haujlwm tau zoo. Kev xaiv hom kom raug thiab kev tuav nws kom zoo yuav ua rau koj lub tshuab ua haujlwm tau zoo thiab ua haujlwm tau zoo.
