Hauv kev tsim khoom lag luam, cov cuab yeej siv tshuab yog cov cuab yeej siv tseem ceeb uas ua kom cov khoom tsim tau cov khoom siv thiab cov khoom.Ib qho tseem ceeb ntawm cov cuab yeej siv tshuab yog spindle, uas nqa cov cuab yeej txiav thiab tig ntawm kev kub ceev los ua haujlwm machining.Lub spindle yuav tsum tau mounted rau bearings uas yuav pab tau nws qhov hnyav thiab tiv taus lub zog generated thaum lub sij hawm machining.
Kev lig kev cai, pob bearings thiab cov menyuam bearings tau siv ntau hom kabmob hauv cov cuab yeej siv tshuab.Txawm li cas los xij, nrog rau kev thov ntau dua rau kev ua haujlwm siab dua thiab kev ua tau zoo, hom tshiab ntawm bearings tau tsim, xws li roj bearings.Gas bearings yog cov kabmob uas tsis muaj kev sib cuag uas siv cov yeeb yaj kiab nyias ntawm cov pa, feem ntau yog cua lossis nitrogen, los txhawb lub zog tig.Lawv muab ntau qhov zoo dua li cov kabmob ib txwm muaj, xws li kev sib txhuam qis, muaj peev xwm ua kom nrawm dua, thiab ua kom zoo dua qub.
Ib qho khoom siv uas tau siv tiav ua cov khoom siv roj hauv cov cuab yeej siv tshuab yog granite.Granite gas bearings muaj ntau yam khoom tshwj xeeb uas ua rau lawv muaj kev xaiv zoo rau kev ua haujlwm siab.Granite yog cov khoom siv ntuj tsim los ntawm cov magma txias, thiab nws muaj cov qauv zoo heev thiab zoo ib yam.Qhov no ua rau nws muaj zog heev rau hnav thiab deformation, txawm tias nyob rau hauv hnyav loads thiab high speeds.
Granite gas bearings kuj muaj qhov sib zog-rau-hnyav heev, uas txhais tau hais tias lawv tuaj yeem txhawb nqa qhov hnyav nrog tsawg deflection.Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov cuab yeej siv tshuab, qhov twg cov ntxaiv tuaj yeem hnyav ntau pua kilograms thiab yuav tsum tau mounted nrog high precision.Tsis tas li ntawd, granite muaj cov coefficient tsawg heev ntawm thermal expansion, uas txhais tau hais tias nws tsis tshua muaj peev xwm deform vim qhov hloov pauv ntawm qhov kub thiab txias.Qhov no yog qhov tseem ceeb hauv cov cuab yeej siv tshuab, qhov twg qhov kub hloov pauv tuaj yeem ua rau muaj kev hloov pauv loj hauv qhov ntev ntawm cov khoom siv machined.
Lub peev xwm ntawm granite roj bearings nyob ntawm ntau yam, xws li qhov loj thiab cov duab ntawm cov kabmob, kev ua haujlwm (ceev, kub, siab), thiab cov khoom siv ntawm granite.Feem ntau, granite roj bearings tuaj yeem txhawb nqa qhov hnyav ntawm ob peb Newtons mus rau ob peb kilo-Newtons, nyob ntawm qhov loj thiab tsim ntawm cov kabmob.Lawv kuj tuaj yeem ua haujlwm ntawm qhov nrawm mus txog ntau txhiab txhiab tus kiv puag ncig ib feeb, uas yog siab dua li cov pob ib txwm muaj lossis cov menyuam bearings.
Hauv kev xaus, granite gas bearings yog ib qho kev cog lus thev naus laus zis rau kev siv high-speed thiab high-precision hauv cov cuab yeej siv tshuab.Lawv muab ntau qhov zoo dua li cov kabmob ib txwm muaj, xws li kev sib txhuam qis, muaj peev xwm ceev dua, thiab ua kom zoo dua qub.Cov kabmob muaj peev xwm ntawm granite gas bearings nyob ntawm ntau yam, tab sis lawv tuaj yeem txhawb nqa siab thiab ua haujlwm ntawm kev kub ceev.Nrog rau kev tshawb nrhiav thiab kev txhim kho txuas ntxiv, granite gas bearings yuav dhau los ua tus qauv hauv cov cuab yeej siv tshuab yav tom ntej.
