Tsim los rau Kev Ua Siab Ntev: Yuav Ua Li Cas Kev Nqus Dej Qis Qis lav qhov ruaj khov ntawm Precision Granite Platforms

Qhov xav tau kev ruaj khov ntawm qhov ntev hauv kev ntsuas qhov tseeb yog qhov tseem ceeb heev. Txawm hais tias granite tau txais kev qhuas thoob ntiaj teb rau nws qhov kev ruaj khov thermal thiab kev co damping, ib lo lus nug feem ntau tshwm sim los ntawm cov engineers hauv cov huab cua noo: Cov dej noo cuam tshuam li cas rau lub platform granite precision?

Nws yog ib qho kev txhawj xeeb uas muaj tseeb, vim tias txhua yam khoom siv ua lub dav hlau siv rau micrometers lossis CMMs yuav tsum tiv taus kev cuam tshuam ntawm ib puag ncig. Cov lus teb luv luv yog: vim yog cov khoom siv thiab kev ua tiav uas tau xaiv zoo, cov granite zoo precision yog qhov tiv taus cov dej noo.

Lub Luag Haujlwm ntawm Kev Nqus Dej Tsawg hauv Metrology

Granite, ua ib lub pob zeb ntuj, muaj qee qhov porosity. Txawm li cas los xij, cov hom granite dub tshwj xeeb uas ZHHIMG siv rau kev siv metrology raug xaiv tshwj xeeb rau lawv cov qauv ntom ntom, zoo, uas ua rau muaj qhov nqus dej tsawg kawg nkaus.

Cov granite metrology-qib feem ntau muaj qhov nqus dej tsawg dua 0.13% (ntau hom hwm zoo dua, feem ntau ze rau 0.07% lossis tsawg dua). Tus cwj pwm no tseem ceeb heev rau kev tswj hwm qhov tseeb mus sij hawm ntev:

• Txo Qhov Hygroscopic Expansion: Txawm hais tias qee cov ntaub ntawv tuaj yeem o lossis cog lus ntau thaum lawv nqus lossis tso cov dej noo (hygroscopic expansion), qhov porosity qis heev ntawm precision granite ua rau qhov no txwv tsis pub muaj. Tus nqi ntawm cov dej uas lub pob zeb nqus tau yog qhov tsis tseem ceeb, tiv thaiv txhua qhov kev hloov pauv loj uas yuav cuam tshuam rau qhov chaw tiaj tus.
• Kev Tiv Thaiv Xeb: Tej zaum qhov zoo dua yog qhov kev tiv thaiv uas nws muab rau koj cov cuab yeej muaj nqis. Yog tias lub phaj saum npoo muaj porosity siab, nws yuav khaws cov dej noo ze ntawm qhov chaw. Cov dej noo no tuaj yeem ua rau xeb thiab xeb ntawm cov hlau ntsuas, cov khoom siv, thiab cov khoom tso rau ntawm granite, ua rau hnav ua ntej thiab ntsuas cov kab mob. Qhov porosity qis ntawm peb cov Cheebtsam Dub Granite txo qhov kev pheej hmoo no, txhawb nqa ib puag ncig tsis muaj xeb.

Av noo vs. Qhov tseeb: Nkag siab txog qhov kev hem thawj tiag tiag

Txawm hais tias granite nws tus kheej tiv taus qhov kev hloov pauv ntawm qhov chaw noo noo, peb yuav tsum piav qhia qhov sib txawv ntawm cov khoom siv ruaj khov thiab kev tswj hwm ib puag ncig hauv chav kuaj mob:

Ua cov kws tshaj lij hauv Ultra-Precision Platforms, peb xav kom cov neeg siv khoom tswj hwm qhov chaw uas muaj av noo, zoo tshaj plaws yog nruab nrab ntawm 50% thiab 60% Relative Humidity (RH). Qhov kev tswj hwm no tsis yog hais txog kev tiv thaiv lub granite slab tab sis yog hais txog kev tiv thaiv tag nrho lub metrology system (CMMs, gauges, optics) thiab xyuas kom meej tias huab cua ruaj khov.

ZHHIMG qhov Kev Lav Paub Txog Kev Ruaj Ntseg Mus Ib Txhis

Cov granite uas peb xaiv—uas paub zoo txog nws qhov ceev thiab cov noob zoo—muab lub hauv paus ruaj khov tiv thaiv tau ob qho tib si qhov kub thiab dej noo hloov pauv. Peb txoj kev cog lus siv granite nrog lub zog tshwj xeeb siab ua kom koj tau txais lub rooj tshuaj xyuas ruaj khov, tiv taus xeb uas yuav khaws nws qhov tiaj tiaj thiab kev ncaj ncees rau ntau xyoo, tsuas yog xav tau kev kho dua tshiab los ntawm cov kws tshaj lij vim yog kev hnav, tsis yog kev puas tsuaj ntawm ib puag ncig.

Thaum koj nqis peev rau hauv ZHHIMG Precision Granite puag, koj tab tom nqis peev rau hauv lub hauv paus tsim los rau qhov kev ntsuas siab ntawm txhua qhov chaw ntsuas siab.
