Cov khoom siv granite ua lub luag haujlwm tseem ceeb hauv kev tsim khoom lag luam niaj hnub thiab kev ntsuas hauv chaw kuaj mob. Raws li cov chaw siv los ntsuas qhov tseeb, lawv siv rau kev ntsuas qhov tseeb, kev sib dhos, kev sib dhos tshuab, thiab kev tshuaj xyuas zoo. Lawv qhov ruaj khov, kev tiv thaiv corrosion, thiab cov khoom tsis muaj hlau nplaum ua rau granite zoo yog cov khoom siv zoo tshaj plaws rau cov twj paj nruag, cov hauv paus tshuab, thiab cov cuab yeej ua haujlwm raug. Txhawm rau kom ntseeg tau tias muaj qhov tseeb mus sij hawm ntev, cov qauv granite yuav tsum tau teeb tsa kom raug thiab rov qab kho dua tsis tu ncua thaum hnav, puas tsuaj, lossis puas tsuaj tsis tau xav txog. Kev nkag siab txog cov txheej txheem kho pab ua kom lub neej ua haujlwm ntev dua thiab tswj kev ntseeg siab ntawm cov khoom siv tseem ceeb.
Kev teeb tsa kom raug yog lub hauv paus ntawm qhov tseeb ntawm cov khoom granite. Thaum lub sijhawm teeb tsa, cov kws kho tshuab feem ntau siv cov qib hluav taws xob lossis cov ncej los teeb tsa qhov chaw ua haujlwm. Cov ntsia hlau txhawb nqa ntawm lub rooj sawv granite raug kho kom ua tiav kev ruaj khov kab rov tav, thaum lub rooj sawv nws tus kheej feem ntau yog welded los ntawm cov yeeb nkab plaub fab uas muaj zog kom txo qis kev co thaum siv. Tom qab lub platform raug tsa thiab muab tso rau ntawm lub rooj sawv, cov ceg leveling hauv qab lub thav duab raug kho kom zoo kom ntseeg tau tias tag nrho cov khoom sib dhos tseem ruaj khov thiab tsis txav mus los. Txhua qhov tsis ruaj khov ntawm theem no yuav cuam tshuam ncaj qha rau kev ntsuas kev ua tau zoo.
Dhau sijhawm, txawm tias cov granite zoo tuaj yeem qhia me ntsis hnav lossis poob qhov tiaj tiaj vim yog siv ntau, kev faib khoom tsis raug, lossis cov teebmeem ib puag ncig. Thaum qhov no tshwm sim, kev kho dua tshiab yog qhov tseem ceeb kom coj cov khoom rov qab mus rau nws qib qhov tseeb qub. Cov txheej txheem kho ua raws li cov txheej txheem tswj hwm thiab cov kauj ruam tes-lapping. Theem thawj zaug yog kev sib tsoo ntxhib, uas tshem tawm qhov deformation ntawm qhov chaw thiab rov tsim kom muaj qhov tuab sib npaug thiab qhov tiaj tiaj ua ntej. Kauj ruam no npaj lub pob zeb rau kev ua haujlwm kom meej dua.
Thaum qhov chaw tau kho los ntawm kev sib tsoo ntxhib, cov kws tshaj lij pib sib tsoo semi-fine kom tshem tawm cov khawb tob dua thiab ua kom zoo dua qhov geometry. Theem no yog qhov tseem ceeb rau kev ua tiav lub hauv paus ruaj khov thiab ruaj khov ua ntej nkag mus rau theem kawg ntawm qhov tseeb. Tom qab sib tsoo semi-fine, cov granite raug lapped manually siv cov cuab yeej tshwj xeeb thiab cov abrasives zoo heev. Cov kws txawj ua haujlwm - ntau tus nrog ntau xyoo ntawm kev paub - ua qhov kev ua haujlwm no los ntawm tes, maj mam coj qhov chaw mus rau nws qhov tseeb xav tau. Hauv cov ntawv thov siab, cov txheej txheem yuav rov ua dua ntau zaus kom ua tiav micrometer lossis txawm tias sub-micrometer flatness.
Thaum twg qhov kev ntsuas raug raws li qhov xav tau lawm, qhov chaw granite yuav raug txhuam. Kev txhuam yuav ua rau qhov chaw du, txo qhov roughness, ua rau tsis yooj yim hnav, thiab ua kom ruaj khov mus ntev. Thaum kawg ntawm cov txheej txheem, cov khoom yuav raug ntxuav, tshuaj xyuas, thiab kuaj xyuas raws li cov qauv thoob ntiaj teb. Qhov chaw granite uas tsim nyog yuav tsum tsis muaj qhov tsis zoo xws li qhov av, kab nrib pleb, xeb, khawb, lossis lwm yam tsis zoo uas yuav cuam tshuam rau kev ua haujlwm. Txhua qhov khoom tiav lawm yuav raug kuaj xyuas kom paub tseeb tias ua raws li qib xav tau.
Ntxiv rau kev kho dua tshiab, cov khoom siv granite lawv tus kheej raug kuaj xyuas hauv chaw kuaj mob ua ntej nkag mus rau hauv kev tsim khoom. Cov txheej txheem kuaj feem ntau suav nrog kev ntsuam xyuas kev tiv thaiv kev hnav, kev kuaj xyuas qhov ntev, kev ntsuas qhov hnyav thiab qhov ceev, thiab kev ntsuas dej nqus. Cov qauv raug txhuam, txiav rau qhov ntev tus qauv, thiab kuaj xyuas raws li cov xwm txheej tswj hwm. Lawv raug hnyav ua ntej thiab tom qab cov voj voog abrasive, muab tso rau hauv dej kom ntsuas qhov saturation, thiab ziab hauv qhov kub tas li lossis qhov chaw nqus tsev nyob ntawm seb lub pob zeb yog granite ntuj lossis pob zeb dag. Cov kev xeem no lees paub tias cov khoom siv ua tau raws li qhov yuav tsum tau ua kom ruaj khov thiab ruaj khov hauv kev tsim kho precision.
Cov khoom siv granite, txawm tias siv rau hauv cov chaw kuaj ntsuas lossis hauv cov tshuab kev lag luam siab heev, tseem ceeb heev rau hauv cov teb uas xav tau cov chaw ruaj khov. Nrog kev teeb tsa kom zoo, kev tshuaj xyuas tsis tu ncua, thiab kev kho dua tshiab, cov platform granite thiab cov qauv tuaj yeem tswj tau lawv qhov tseeb tau ntau xyoo. Lawv cov txiaj ntsig zoo - kev ruaj khov ntawm qhov ntev, kev tiv thaiv corrosion, thiab kev ntseeg tau mus sij hawm ntev - ua rau lawv yog cov cuab yeej tseem ceeb hauv kev tsim khoom raug, kev tshawb fawb, thiab cov chaw tsim khoom tsis siv neeg.
