Hauv kev tsim khoom siab heev, XYZ precision gantry platform muaj cov kev cai nruj heev rau kev ua tau zoo ntawm cov ntaub ntawv. Cov granite ntuj, nrog rau ntau yam khoom zoo heev, tau dhau los ua qhov kev xaiv zoo dua li marble.
I. Kev Sib Piv ntawm Cov Khoom Siv Kho Tshuab
Kev tawv thiab kev hnav tsis kam
Granite feem ntau yog ua los ntawm cov zaub mov xws li quartz thiab feldspar, nrog Mohs hardness ntawm 6 txog 7. Nws tuaj yeem tiv taus kev hnav thiab tswj qhov tseeb ntawm lub platform thaum siv ntev thiab kev txav mus los ntau zaus. Qhov sib piv, cov khoom tseem ceeb ntawm marble, calcium carbonate, muaj qhov nyuaj tsawg, nrog Mohs hardness ntawm tsuas yog 3 txog 5. Nyob rau hauv tib qho kev sib txhuam thiab siab, nws yooj yim khawb thiab hnav, uas cuam tshuam rau qhov tseeb thiab lub neej kev pabcuam ntawm lub platform.
Kev Rigidity thiab Stability
Granite muaj cov qauv ntom ntom, nrog rau cov khoom hauv cov pob zeb sab hauv sib txuas ua ke, ua rau nws muaj kev ruaj khov zoo heev. Thaum raug kev thauj khoom hnyav thiab kev ntxhov siab ntawm lub tshuab, nws tuaj yeem tswj tau qhov ruaj khov ntawm cov qauv thiab tsis yooj yim rau kev hloov pauv. Txawm li cas los xij, marble muaj ntau cov qauv thiab cov kab nrib pleb me me sab hauv, thiab nws qhov kev ruaj khov tsis muaj zog. Thaum lub sijhawm thauj khoom ntau lossis siv ntev, nws yuav tsim cov kab nrib pleb lossis kev hloov pauv vim muaj kev ntxhov siab, cuam tshuam rau kev ruaj khov thiab qhov tseeb ntawm lub platform.
II. Qhov sib txawv ntawm kev ua haujlwm thermal
Coefficient ntawm thermal expansion
Granite muaj qhov coefficient qis heev ntawm kev nthuav dav thermal, kwv yees li 4-8 × 10⁻⁶ / ℃, thiab nws qhov loj me hloov me ntsis thaum qhov kub hloov pauv. Qhov no yog qhov tseem ceeb rau cov platforms gantry XYZ precision siab, uas tuaj yeem tiv thaiv kev hloov pauv thermal los ntawm kev hloov pauv kub thiab xyuas kom meej tias qhov tseeb ntawm lub platform tsis cuam tshuam. Qhov coefficient ntawm kev nthuav dav thermal ntawm marble yog qhov siab heev. Hauv ib puag ncig nrog kev hloov pauv kub loj, nws yooj yim rau kev nthuav dav thermal thiab kev cog lus, uas tuaj yeem ua rau muaj kev hloov pauv ntawm qhov loj me thiab qhov tseeb ntawm lub platform.
Kev ua kom sov tau zoo
Granite muaj cov thermal conductivity qis. Thaum cua sov hauv zos, cov cua sov maj mam diffuses, uas tuaj yeem txo qhov tshwm sim ntawm thermal deformation. Marble muaj cov thermal conductivity siab. Hauv cov xwm txheej thov xws li laser processing uas tsim cov cua sov ntau, cov cua sov yuav raug coj thiab diffuses, ua rau cov thermal deformation tsis sib xws ntawm lub platform thiab cuam tshuam rau qhov tseeb ntawm kev ua.
Iii. Qhov sib txawv ntawm cov yam ntxwv ntawm kev ntub dej
Granite muaj cov khoom zoo heev rau kev co, thiab nws cov qauv sab hauv tuaj yeem nqus thiab txo qhov kev co zog. Thaum lub sijhawm ua haujlwm ntawm lub platform gantry, kev co tuaj yeem raug txo kom sai, txo qhov cuam tshuam ntawm kev co rau kev ua tiav thiab lub neej ntawm cov khoom siv. Kev ua haujlwm ntawm marble tsis muaj zog heev, ua rau nws nyuaj rau txo qhov kev co zoo li granite, uas tsis zoo rau kev ua haujlwm raug.
Iv. Kev Xav Txog Kev Ruaj Ntseg Tshuaj
Granite muaj kev ruaj khov tshuaj lom neeg zoo thiab tiv taus acid thiab alkali corrosion. Hauv qee qhov chaw ua haujlwm tshwj xeeb, xws li cov tshuaj reagents lossis cov pa roj corrosive, granite platforms tuaj yeem tswj tau qhov ruaj khov ntawm cov khoom siv thiab tiv thaiv kev xeb. Lub ntsiab lus tseem ceeb ntawm marble, calcium carbonate, yog qhov yooj yim rau cov tshuaj lom neeg tshuaj lom neeg nrog cov kua qaub thiab yooj yim corroded hauv cov chaw acidic, ua rau puas tsuaj rau lub platform nto thiab txo qis qhov tseeb.
V. Lub Neej Pabcuam thiab Tus Nqi Txij Nkawm
Vim yog qhov zoo ntawm granite hais txog qhov nyuaj, hnav tsis kam thiab thermal stability, nws lub neej ua haujlwm feem ntau ntev dua li marble. Ntxiv mus, granite tsis yooj yim hnav thiab rhuav, muaj qhov deformation tsawg kawg nkaus, lub voj voog txij nkawm ntev, thiab tus nqi txij nkawm qis. Vim yog cov teeb meem xws li yooj yim hnav thiab thermal stability tsis zoo, marble xav tau kev kho dua tshiab, kho thiab hloov pauv ntau zaus, ua rau tus nqi txij nkawm siab dua.
Xaus lus, granite ntuj ua tau zoo dua marble hauv ntau yam xws li cov khoom siv kho tshuab, cov khoom siv thermal, cov yam ntxwv damping, kev ruaj khov tshuaj lom neeg, lub neej ua haujlwm thiab cov nqi txij nkawm. Yog li ntawd, nws tau dhau los ua cov khoom siv zoo tshaj plaws rau XYZ precision gantry platforms.
