Hauv kev lag luam kev lag luam, lub tshuab ntsuas peb-coordinate (CMM) yog ib qho cuab yeej tseem ceeb rau kev ua tiav kev tshuaj xyuas qhov ntev thiab daim ntawv thiab qhov chaw ntsuas kev kam rau siab, thiab nws qhov kev ntsuas raug cuam tshuam ncaj qha rau qhov zoo ntawm cov khoom. Granite precision platforms, nrog lawv cov kev ua tau zoo tshaj plaws, tau dhau los ua qhov kev xaiv zoo tshaj plaws rau cov tshuab ntsuas peb-coordinate, muab kev lees paub txhim khu kev qha rau kev kuaj pom tseeb.
1. Kev ua kom raug thiab ruaj khov heev
Cov platform granite precision muaj kev ruaj khov zoo heev thiab qhov coefficient qis heev ntawm thermal expansion, uas tsuas yog (4-8) × 10⁻⁶ / ℃. Hauv qhov chaw ua lag luam nyuaj thiab hloov pauv tau, txawm tias qhov kub hloov pauv, qhov kev hloov pauv ntawm lub platform tsis tseem ceeb, ua kom tsis txhob muaj qhov yuam kev ntsuas los ntawm thermal deformation. Lub caij no, cov qauv siv lead ua sab hauv ntawm granite yog ntom. Tom qab ntau txhiab xyoo ntawm kev ua haujlwm geological, kev ntxhov siab sab hauv tau raug tshem tawm ntuj, thiab yuav tsis muaj kev laus deformation. Qhov no ua kom ntseeg tau tias muaj kev ruaj khov mus sij hawm ntev ntawm qhov ntsuas thiab khaws qhov tseeb ntawm qhov chaw thiab rov ua qhov tseeb ntawm lub tshuab ntsuas peb-coordinate ntawm qib siab txhua lub sijhawm.
Qhov thib ob, kev tiv thaiv kev co thiab kev ua kom tsis muaj zog zoo heev
Qhov kev co uas tsim los ntawm kev ua haujlwm ntawm cov cuab yeej siv tshuab thiab qhov pib thiab nres ntawm cov khoom siv hauv lub chaw ua haujlwm ntau lawm tuaj yeem cuam tshuam rau qhov tseeb ntawm lub tshuab ntsuas peb-coordinate. Granite muaj cov khoom zoo heev damping, nrog rau qhov piv damping txog li 0.05-0.1, uas tuaj yeem ua rau lub zog ntawm kev co sab nraud sai sai. Thaum cov kev co sab nraud raug xa mus rau lub platform, granite tuaj yeem tswj cov kev co hauv lub sijhawm luv luv, txo qhov cuam tshuam kev co thaum lub sijhawm ntsuas, ua kom ntseeg tau tias qhov tseeb ntawm kev sib cuag ntawm qhov ntsuas thiab qhov chaw ua haujlwm, thiab ua rau cov ntaub ntawv ntsuas raug thiab txhim khu kev qha dua.
Peb. Kev ua kom tawv thiab hnav tsis kam
Granite muaj qhov nyuaj ntawm 6 txog 7 ntawm Mohs scale, qhov ceev ntawm 2.7 txog 3.1g/cm³, thiab zoo heev rau kev hnav ntawm qhov chaw. Thaum siv lub tshuab ntsuas peb-coordinate ntev, kev thauj khoom thiab tshem tawm cov khoom ua haujlwm ntau zaus thiab kev txav ntawm cov ntsuas probes yuav tsis ua rau hnav ntawm qhov chaw ntawm lub platform granite. Txawm tias tom qab siv ntau xyoo, qhov chaw ntawm lub platform tseem tuaj yeem tswj tau qhov tiaj tus thiab du, ua kom lub neej ua haujlwm ntawm lub tshuab ntsuas peb-coordinate ntev dua thiab txo cov nqi kho khoom siv.
Qhov thib plaub, kev ruaj khov tshuaj lom neeg muaj zog
Hauv cov chaw tsim khoom lag luam, feem ntau muaj cov tshuaj lom neeg xws li cov kua txiav thiab cov roj lubricating, thiab qee qhov kuj tseem yuav muaj cov pa roj corrosive nrog. Granite muaj cov khoom siv tshuaj ruaj khov, ntau qhov pH kam rau siab (1-14), tuaj yeem tiv taus kev yaig ntawm cov tshuaj lom neeg, thiab tsis yooj yim xeb lossis xeb. Qhov no tsis yog tsuas yog tiv thaiv lub platform nws tus kheej xwb tab sis kuj ua kom muaj ib puag ncig ua haujlwm huv si rau lub tshuab ntsuas peb-coordinate, tiv thaiv kev ntsuas qhov tseeb thiab lub neej ua haujlwm ntawm cov khoom siv los ntawm kev cuam tshuam los ntawm cov tshuaj lom neeg.
Cov platform granite precision, nrog lawv qhov zoo ntawm kev ua haujlwm siab, kev ruaj khov siab, kev tiv thaiv kev co, kev hnav tsis kam thiab kev ruaj khov tshuaj lom neeg, muab lub hauv paus ruaj khov rau kev kuaj pom tseeb ntawm peb-kev ntsuas kev sib koom tes thiab ua lub luag haujlwm tseem ceeb hauv kev tswj hwm zoo ntawm kev tsim khoom niaj hnub.
