Kev txhim kho ntawm kev lag luam luam ntawv tau hloov zuj zus los ntawm kev hloov pauv ntawv yooj yim mus rau qhov dav siv ntau yam offset luam ntawv thiab cov ntawv luam tawm zoo dua qub. Kev ntseeg tom qab ntawm cov qauv kev txhim kho no yog qhov tseeb raws li cov tuam txhab xav tau kev txhim kho kom txuas ntxiv ntawm kev tsim khoom tsim thiab txhim kho cov khoom sib tw thiab cov txiaj ntsig zoo hauv kev ua lag luam.
Yog li no, luam ntawv thiab lwm yam ua tshuab thiab khoom siv ntawm ntau cov tswv yim' qhov ntsuas tsis tu ncua tau tshwm sim hauv kev ua lag luam ntawm lub nrawm nrawm, koom tes nrog thiab ua dhau ntawm qhov kev cia siab ntawm cov tuam ntxhab. Txawm li cas los xij, thaum cov tshuab siab heev no tau hloov mus rau cov hom phiaj kev tsim tawm nruab hnub thiab hmo ntuj, ntau cov haujlwm ua haujlwm ntsig txog" cov teeb meem me" tseem yuav tshwm sim, xws li kev tu tsev.
Thaum lub tshuab puas lawm, cov chaw tsim khoom lag luam feem ntau xav tias nws yog los ntawm kev ua haujlwm coj zoo li qub thiab tsim kua muag. Txawm li cas los xij, hnub no' s tshuab yog ua los ntawm high-quality alloy steel thiab yuav tsum siv tau ntev. Tom qab ntawd, tom qab cov tuam txhab tsim nqi them cov nqi kho tsev thiab cov kev mob siab ntawm ncua ntau lawm, lawv maj mam pib pom lub luag haujlwm tseem ceeb los ntawm pab pawg kho khoom siv los tswj cov haujlwm ntawm cov tshuab luam ntawv. Cov khoom lag luam tshuaj muaj feem xyuam nrog zoo li tsis zoo. Tej zaum vim tias qhov xaiv cov khoom siv tsis raug, nws yuav tsis ua rau muaj kev cuam tshuam phem tam sim ntawm cov khoom tiav tiav los ntawm cov tuam txhab tsim khoom. Cov cuab yeej siv tshuab feem ntau siv rau lub sijhawm ntev ua ntej pom tias muaj teeb meem.
