Hauv cov roj teeb lithium kev tsim tawm, kev xaiv ntawm lub tshuab siv lub tshuab nqa khoom ua si lub luag haujlwm tseem ceeb hauv kev ua haujlwm, precision, thiab thiav ntawm cov txheej txheem ntau lawm. Ob cov ntaub ntawv sib txawv rau cov roj teeb lithium tshuab hluav taws xob yog granite thiab hlau. Txhua cov ntaub ntawv muaj nws tus kheej zoo thiab qhov tsis zoo, yog li cov tuam ntxhab yuav tsum muab lawv.
Granite lub hauv paus yog paub rau lawv qhov kev ruaj khov ruaj khov thiab poob siab-nqus cov khoom. Granite lub ntuj ntom ua rau nws ua kom muaj kev nqus tau zoo, uas yog qhov tseem ceeb rau cov txheej txheem uas yuav tsum muaj qhov ntsuas siab. Cov cuab yeej no me me rau kev pheej hmoo ntawm kev tsis xws luag nyob rau hauv lub roj teeb hlwb, ua kom cov khoom lag luam siab dua. Tsis tas li ntawd, cov granite yog resistant rau thermal expansion, tswj qhov tseeb ntawm qhov tseeb txawm tias nyob hauv kev sib txawv. Txawm li cas los xij, cov pob zeb granite tuaj yeem kim dua thiab muab cov khoom siv tsawg dua hauv cov ntsiab lus hloov kho.
Ntawm qhov tod tes, cov hauv paus hlau yog qhov kev nyiam rau lawv lub zog thiab lub zog. Cov hlau yog cov khoom siv muaj peev xwm tiv thaiv cov nra hnyav thiab tsis tshua tau tawg kom tawg dua li granite. Qhov no ua rau cov hauv paus steel haum rau lub ntim ntau ib puag ncig cov tshuab cov khoom yuav muaj kev hnav hnyav thiab ntuag. Tsis tas li ntawd, cov hauv paus hlau tuaj yeem hloov kho yooj yim lossis kho, muab cov chaw tsim khoom lag luam nrog kev hloov pauv ntau dua. Txawm li cas los xij, cov hlau muaj kev cuam tshuam ntau dua los ntawm kev co thiab thermal nthuav dav, uas tuaj yeem ua rau tsis muaj tseeb nyob rau hauv kev tsim khoom lag luam.
Hauv cov ntsiab lus, kev xaiv ntawm granite thiab steel puag hauv lithium roj teeb machinery tiag tiag nyob ntawm cov kev xav tau tshwj xeeb ntawm cov chaw tsim khoom. Granite muaj qhov ua poob siab zoo heev thiab thermal stability, uas yog qhov zoo tagnrho rau cov ntawv thov precision. Hauv kev sib piv, steel muaj lub zog thiab kev yoog tau, uas haum rau cov neeg muaj haujlwm ntau lawm. Cov neeg tsim khoom lag luam yuav tsum ua kom zoo rau qhov tsim nyog tshaj plaws substrate rau lawv cov roj teeb lithium roj teeb.
