Granite yog ib qho kev xaiv nrov rau kev sib dhos cov khoom siv tau ntau xyoo. Txawm hais tias hlau yuav zoo li lwm txoj hauv kev rau cov khoom lag luam siab, muaj ntau qhov laj thawj vim li cas granite yog cov khoom nyiam.
Ua ntej, granite muaj qib siab ntawm qhov ruaj khov. Qhov no txhais tau hais tias nws tsis tshua muaj kev sib tw lossis flex thaum thauj lossis hloov pauv kub. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm precision los ua ke pab kiag li lawm, raws li ib tug me ntsis warp los yog flex yuav ua rau ua yuam kev nyob rau hauv lub sib dhos txheej txheem. Hlau, ntawm qhov tod tes, paub txog kev nthuav dav thiab cog lus nyob rau hauv cov cua sov uas tuaj yeem muaj kev cuam tshuam tsis zoo rau kev sib dhos qhov tseeb.
Thib ob, granite muaj cov coefficient tsawg ntawm thermal expansion. Qhov no txhais tau hais tias txawm tias muaj qhov kub thiab txias, granite yuav tsis nthuav lossis cog lus loj - kom ntseeg tau qhov tseeb. Qhov no yog qhov tseem ceeb rau cov khoom siv sib dhos precision, vim tias kev hloov pauv ntawm qhov loj lossis qhov loj tuaj yeem ua rau tsis raug.
Thirdly, granite muaj zoo damping zog. Qhov no txhais tau hais tias kev vibrations yog absorbed thiab dissipated sai, uas ua rau ib tug ntau ruaj khov chaw ua hauj lwm rau cov precision sib dhos li. Qhov tseem ceeb no ib leeg yog txaus los ua pov thawj qhov nyiam ntawm granite tshaj hlau, qhov twg kev vibrations tuaj yeem ua rau muaj kev ua yuam kev hauv cov txheej txheem sib dhos.
Thaum kawg, granite yog cov khoom siv tawv heev thiab ruaj khov. Nws yog resistant rau hnav thiab tsis cuam tshuam rau corrosion, ua rau nws yog ib tug nqi-zoo xaiv nyob rau hauv lub sij hawm ntev. Nws kuj yuav tsum tau saib xyuas me ntsis thiab tuaj yeem siv tau ntau xyoo, ua rau nws yog qhov kev nqis peev zoo tshaj plaws rau cov khoom siv sib dhos precision.
Hauv kev xaus, thaum hlau yuav zoo li ib qho kev xaiv siv tau rau cov khoom siv sib dhos, granite tseem yog cov khoom nyiam. Nws qhov ruaj khov qhov ntev, qis coefficient ntawm thermal expansion, zoo heev damping zog thiab durability ua rau nws yog ib qho zoo tagnrho xaiv rau high-precision daim ntaub ntawv. Nws kuj tseem raug nqi zoo nyob rau lub sijhawm ntev, ua rau nws muaj peev txheej tsim nyog.
