Precision granite txaj thiab hlau txaj yog ob hom ntawm txaj siv nyob rau hauv ntau yam lag luam xws li kev tsim, machining, thiab metrology. Ob leeg muaj lawv cov yam ntxwv tshwj xeeb, qhov zoo, thiab cov kev txwv, thiab lawv txoj kev siv yog nyob ntawm cov ntawv thov tshwj xeeb. Hauv tsab xov xwm no, peb yuav sib piv ob hom ntawm lub txaj txaj raws li ob peb yam tseem ceeb los pab kom nkag siab txog lawv qhov sib txawv thiab kev siv.
1. Khoom siv
Qhov sib txawv tseem ceeb ntawm precision granite txaj thiab hlau txaj yog cov khoom siv. Precision granite txaj yog ua los ntawm cov khoom siv ntuj granite, uas paub txog nws qhov kev ruaj ntseg, rigidity, thiab thermal stability. Ntawm qhov tod tes, lub txaj hlau yog ua los ntawm ntau yam hlau xws li hlau, cam khwb cia hlau, lossis txhuas.
2. Kev nruj
Precision granite txaj muaj qhov nruj dua piv rau lub txaj hlau, uas ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov siab xws li kev tsim kho qhov muag thiab hluav taws xob, calibration, thiab tshuaj xyuas. Granite cov khoom tawv tawv kom ntseeg tau tias lub txaj saum npoo tseem tiaj tus thiab ruaj khov txawm tias nyob rau hauv qhov hnyav hnyav lossis cuam tshuam tam sim ntawd, thiab kev vibrations xa mus rau qhov chaw ua haujlwm raug txo qis.
3. Flatness
Lub flatness ntawm lub txaj saum npoo yog ib qho tseem ceeb uas cuam tshuam rau qhov tseeb thiab qhov tseeb ntawm lub workpiece. Precision granite txaj tau zoo heev flatness, feem ntau nyob rau hauv ob peb microns, kom ntseeg tau tias zoo ib yam nyob rau hauv tag nrho cov saum npoo. Nyob rau hauv sib piv, lub txaj hlau tej zaum yuav muaj ib co irregularities thiab undulations, uas yuav cuam tshuam rau lub workpiece qhov seem ntawm qhov tseeb.
4. Thermal stability
Precision granite txaj muaj siab thermal stability thiab tsis tshua muaj coefficient ntawm thermal expansion, ua rau nws zoo tagnrho rau cov ntawv thov uas yuav tsum tau kub-tswj ib puag ncig. Lub txaj granite tseem tsis cuam tshuam los ntawm kev hloov pauv kub, ua kom cov khoom ua haujlwm qhov tseeb ntawm qhov sib txawv ntawm ib puag ncig. Nyob rau hauv sib piv, hlau txaj saum npoo muaj ntau dua coefficients ntawm thermal expansion, uas yuav cuam tshuam rau lub workpiece qhov ntev thaum lub sij hawm kub hloov.
5. Corrosion Resistance
Hlau txaj saum npoo yog feem ntau ua rau corrosion tshaj granite nto, uas yuav ua rau xeb thiab pitting ntawm lub txaj saum npoo. Qhov no tuaj yeem cuam tshuam qhov raug thiab precision ntawm lub workpiece. Nyob rau hauv sib piv, granite nto yog heev resistant rau corrosion, ua rau nws ib tug zoo tagnrho xaiv rau siv nyob rau hauv hnyav ib puag ncig.
6. Tus nqi
Precision granite txaj yog kim piv rau lub txaj hlau vim yog tus nqi siab ntawm cov khoom siv granite thiab nws cov kev cuam tshuam thiab kev ua tiav. Hlau txaj saum npoo yog tsis tshua kim thiab dav, ua rau lawv yog ib qho kev xaiv nrov rau kev siv dav dav.
Nyob rau hauv xaus, precision granite txaj thiab hlau txaj yog txawv nyob rau hauv cov nqe lus ntawm cov khoom, nruj, flatness, thermal stability, corrosion kuj, thiab nqi. Precision granite txaj yog qhov kev xaiv zoo tshaj plaws rau kev siv siab-precision thiab kub-rhiab heev vim nws qhov nruj nruj, flatness, thiab thermal stability, thaum hlau txaj saum npoo yog dav siv rau kev siv dav dav vim lawv cov kav ntev, muaj, thiab nqi- kev ua tau zoo. Qhov kev xaiv ntawm ob yog nyob ntawm qhov kev thov tshwj xeeb, thiab ob qho tib si muaj lawv qhov tshwj xeeb zoo thiab kev txwv.
