Granite thiab marble yog ob qho kev xaiv nrov rau cov khoom siv precision hauv ntau yam lag luam, tshwj xeeb tshaj yog hauv kev ntsuas precision thiab machining. Txawm li cas los xij, muaj qhov sib txawv tseem ceeb hauv lawv lub cev ruaj khov uas tuaj yeem cuam tshuam loj heev rau lawv siv hauv cov ntawv thov no.
Granite yog ib qho kev xaiv uas siv ntau rau cov khoom siv precision vim nws qhov ruaj khov zoo heev. Nws yog ib lub pob zeb igneous uas tuab thiab tawv uas tsim los ntawm kev sib xyaw ua ke qeeb ntawm magma hauv qab lub ntiaj teb. Cov txheej txheem txias qeeb no ua rau muaj cov qauv zoo sib xws, zoo nkauj uas muab granite nws lub zog thiab kev ruaj khov tshwj xeeb. Hauv kev sib piv, marble yog pob zeb metamorphic uas tsim los ntawm kev rov ua dua ntawm limestone hauv qab siab thiab kub. Thaum marble kuj yog cov khoom siv ruaj khov thiab pom tseeb, nws tsis muaj kev ruaj khov thiab lub zog ntawm granite.
Ib qho ntawm qhov sib txawv tseem ceeb hauv kev ruaj khov ntawm lub cev ntawm cov khoom siv granite precision thiab cov khoom siv marble precision yog lawv txoj kev tiv thaiv kev hloov pauv. Granite muaj cov coefficient qis heev ntawm kev nthuav dav thermal, txhais tau tias nws tiv taus kev hloov pauv hauv qhov kub thiab txias. Qhov no ua rau nws yog cov khoom siv zoo tagnrho rau cov khoom siv precision uas xav tau kev ruaj khov ntawm qhov ntau ntawm qhov kub thiab txias. Ntawm qhov tod tes, marble muaj cov coefficient siab dua ntawm kev nthuav dav thermal, ua rau nws yooj yim rau kev hloov pauv ntawm qhov ntev nrog kev hloov pauv ntawm qhov kub thiab txias. Qhov no tuaj yeem yog qhov tseem ceeb hauv kev ntsuas qhov tseeb thiab kev siv tshuab, qhov twg txawm tias qhov kev hloov pauv me me tuaj yeem ua rau tsis raug thiab yuam kev.
Lwm qhov txawv tseem ceeb yog lawv txoj kev tiv taus kev hnav thiab kev sib txhuam. Granite tiv taus kev hnav thiab kev sib txhuam heev, ua rau nws tsim nyog rau cov khoom siv precision uas raug kev sib txhuam thiab kev sib cuag tas li. Nws qhov nyuaj thiab kev ruaj khov ua kom nws tswj tau nws qhov tseeb ntawm qhov ntev dhau sijhawm, txawm tias siv hnyav. Marble, thaum tseem yog cov khoom siv ruaj khov, tsis tiv taus kev hnav thiab kev sib txhuam zoo li granite. Qhov no tuaj yeem yog qhov txhawj xeeb hauv kev siv precision machining qhov twg cov khoom sib cuag tas li nrog lwm cov ntaub ntawv, vim tias qhov muaj peev xwm hnav thiab deformation siab dua nrog cov khoom marble.
Hauv kev ntsuas thiab kev ua haujlwm kom raug, qhov sib txawv ntawm kev ruaj khov ntawm cov khoom granite thiab marble tuaj yeem muaj kev cuam tshuam loj rau qhov tseeb thiab kev ntseeg siab ntawm cov txheej txheem. Cov cuab yeej ntsuas kev tseeb, xws li cov tshuab ntsuas kev sib koom tes thiab cov phaj nto, vam khom kev ruaj khov thiab kev tiaj tus ntawm cov khoom kom ntseeg tau tias muaj kev ntsuas raug thiab rov ua dua. Granite qhov kev ruaj khov zoo dua ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov no, vim nws muab lub hauv paus ruaj khov thiab txhim khu kev qha rau kev ntsuas meej. Ntawm qhov tod tes, qhov kev ruaj khov qis dua ntawm cov khoom marble tuaj yeem ua rau muaj qhov tsis raug thiab tsis sib xws hauv kev ntsuas, ua rau qhov zoo ntawm cov txiaj ntsig tsis zoo.
Ib yam li ntawd, hauv kev ua haujlwm precision, qhov ruaj khov ntawm cov khoom yog qhov tseem ceeb rau kev ua tiav qhov kev kam rau siab thiab qhov ua tiav zoo. Granite feem ntau siv rau lub hauv paus tshuab, cov cuab yeej, thiab cov khoom siv hauv kev siv tshuab vim nws qhov kev ruaj khov tshwj xeeb thiab kev tiv thaiv kev co. Qhov kev ruaj khov no yog qhov tseem ceeb rau kev tswj hwm qhov tseeb ntawm cov txheej txheem machining thiab xyuas kom meej qhov zoo ntawm cov khoom tiav. Marble, nrog nws qhov kev ruaj khov qis dua, tej zaum yuav tsis haum rau cov ntawv thov no vim nws tuaj yeem ua rau muaj kev co tsis xav tau thiab kev hloov pauv qhov ntev uas cuam tshuam rau qhov tseeb thiab qhov zoo ntawm cov khoom siv tshuab.
Xaus lus, qhov sib txawv tseem ceeb ntawm kev ruaj khov ntawm cov khoom granite precision thiab cov khoom marble precision muaj qhov cuam tshuam ncaj qha rau lawv siv hauv kev ntsuas thiab machining. Granite qhov kev ruaj khov tshwj xeeb, kev tiv thaiv kev hloov pauv, thiab kev ruaj khov ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom precision hauv cov ntawv thov no. Nws lub peev xwm los tswj qhov tseeb thiab kev ruaj khov ntawm ntau qhov kub thiab nyob rau hauv kev hnav thiab kev puas tsuaj tas li ua rau nws yog cov khoom siv zoo tagnrho rau cov cuab yeej precision thiab cov khoom machining. Ntawm qhov tod tes, thaum marble yog cov khoom siv zoo nkauj thiab ruaj khov, nws qhov kev ruaj khov qis dua thiab kev tiv thaiv kev hnav thiab kev puas tsuaj ua rau nws tsis haum rau cov ntawv thov precision qhov twg qhov tseeb thiab kev ruaj khov yog qhov tseem ceeb. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau kev xaiv cov khoom siv zoo rau cov khoom precision kom ntseeg tau tias qhov tseeb, kev ntseeg siab, thiab qhov zoo ntawm kev ntsuas thiab machining cov txheej txheem.
