Lub raj zeb zeb yog ib qho tseem ceeb ntawm cov khoom siv hauv ntau yam lag luam. Nws yog feem ntau siv rau kev tsim cov seamless thiab welded raj.
Cov mills no ua haujlwm ntawm lub hauv paus ntsiab lus ntawm kev tsis tu ncua ntawm cov hlau ua haujlwm. Cov khoom siv raw, feem ntau yog nyob rau hauv daim ntawv ntawm ib puag ncig billet los yog lub plhaub hollow, yog dhau los ntawm cov chais thiab tuag. Raws li nws nce mus, cov khoom yog maj mam zoo li mus rau hauv ib tug tubular daim ntawv. Cov txheej txheem suav nrog kev tswj xyuas meej ntawm qhov tsis xws li qhov kub thiab txias, siab, thiab ceev kom ntseeg tau qhov zoo thiab qhov tseeb ntawm qhov kawg ntawm cov khoom.
Tube mills yog siv dav hauv kev tsim cov kav dej rau kev siv xws li roj thiab roj tsheb thauj mus los, kev tsim kho, thiab kev lag luam tsheb. Hauv kev lag luam roj thiab roj, cov raj zoo yog qhov tseem ceeb los tiv thaiv cov xwm txheej hnyav thiab kev kub ntxhov. Hauv kev tsim kho, lawv siv rau cov kav dej, kev txhawb nqa, thiab scaffolding. Kev lag luam automotive siv lub raj mills los tsim cov khoom xws li cov kav dej thiab cov roj.
Kev nce qib hauv tshuab raj tshuab tau ua rau muaj kev ua tau zoo thiab cov khoom zoo dua qub. Niaj hnub nimno tube mills tau nruab nrog lub tshuab computer tswj uas tuaj yeem saib xyuas thiab kho cov txheej txheem tsim khoom hauv lub sijhawm. Lawv kuj muab kev yooj yim dua nyob rau hauv cov nqe lus ntawm qhov loj thiab hom raj uas tuaj yeem tsim tau. Zuag qhia tag nrho, lub raj zeb zeb ua lub luag haujlwm tseem ceeb hauv kev ua kom tau raws li qhov xav tau ntawm kev lag luam sib txawv thiab pab txhawb rau lawv txoj kev loj hlob thiab kev loj hlob.
