Thaum xaiv cov khoom siv rau lub tshuab ua haujlwm siab heev, qhov kev xaiv tsis yog hais txog qhov tawv xwb. Nws yog hais txog kev ruaj khov ntawm thermal, kev co, kev ruaj khov mus sij hawm ntev, thiab tag nrho tus nqi ntawm kev muaj. Peb yam khoom siv tseem ceeb hauv kev sib tham: granite ntuj, engineered ceramics, thiab mineral casting. Txhua yam muaj nws qhov chaw. Tab sis kev nkag siab qhov twg txhua yam zoo tshaj plaws - thiab qhov twg nws tsis zoo - yog qhov sib txawv ntawm lub tshuab uas tuav kaum feem pua ntawm ib micron thiab ib qho uas ploj ntawm qhov spec hauv ib xyoos.
Cov Lus Nug Txog Kev Ruaj Ntseg Thermal
Kev hloov pauv ntawm qhov kub thiab txias yog qhov ua rau tsis muaj kev ua haujlwm tseeb. Lub hauv paus tshuab uas nthuav dav lossis cog txawm tias ob peb microns ib 'meter' ib degree Celsius tuaj yeem ua rau $ 500,000 CMM tsis muaj txiaj ntsig rau kev ua haujlwm siab.
Cov pob zeb granite ntuj muaj ib qho ntawm cov coefficients qis tshaj plaws thiab kwv yees tau zoo tshaj plaws ntawm kev nthuav dav thermal (CTE) ntawm cov ntaub ntawv qauv - feem ntau nyob rau hauv qhov ntau ntawm 4.6 txog 9 × 10⁻⁶ / ° C. Nws cov thermal inertia yog qhov tshwj xeeb: granite yog cov khoom siv "qeeb" uas teb tsawg kawg nkaus rau kev hloov pauv kub ambient, ua rau nws yog tus qauv kub raucov tshuab ntsuas sib koom testhiab cov platform metrology.Ntawm ZHHIMG®, peb cov granite dub ZHHIMG® ua tiav qhov ceev ntawm ≈3100 kg / m³ - siab dua li feem ntau cov granites dub European thiab Asmeskas - uas ua rau nws cov thermal mass thiab kev ruaj khov ntxiv.
Cov khoom siv ua los ntawm cov khoom siv av nplaum, tshwj xeeb yog silicon carbide (SiC) thiab aluminium oxide (Al₂O₃), muab cov nqi CTE qis dua (3–5 × 10⁻⁶/°C) thiab kev ua kom sov zoo dua (10–30 W/mK piv rau granite 1–3 W/mK). Qhov no txhais tau tias cov khoom siv av nplaum tuaj yeem tso cua sov sai dua, tab sis lawv nyuaj dua rau kev siv tshuab thiab kim dua los tsim cov qauv loj.
Kev ua cov ntxhia (qee zaum hu ua polymer concrete lossis epoxy granite) muaj CTE kwv yees li 8–12 × 10⁻⁶/°C—siab dua li granite ntuj thiab tsis paub tseeb vim muaj cov epoxy resin. Txawm li cas los xij, kev ua cov ntxhia muaj kev kub siab, tiv taus kev hloov pauv sai thiab muab ib puag ncig ruaj khov rau kev ua haujlwm CNC siab uas cov motors tsim cua sov tseem ceeb.
Qhov Damping Factor
Kev co yog tus yeeb ncuab ntawm qhov tiav ntawm qhov chaw thiab kev ntsuas qhov tseeb. Hauv kev ua haujlwm ceev ceev CNC milling, nws ua rau muaj kev sib tham. Hauv kev tshuaj xyuas semiconductor, txawm tias qhov kev co me me tuaj yeem ua rau muaj qhov yuam kev ntsuas. Granite ntuj tsim tshem tawm kev co 5-10 npaug zoo dua li hlau cam khwb cia. Nws cov qauv crystalline muab kev co uas txo qhov kev sib tham ntawm lub tshuab thiab ncaj qha txhim kho qhov tiav ntawm qhov chaw thiab lub neej ntawm cov cuab yeej. Txawm li cas los xij, kev casting minerals coj kev co ntxiv mus. Lub epoxy resin matrix hauv kev casting minerals nqus kev co zoo dua li cov qauv pob zeb crystalline. Qee qhov chaw tshaj tawm tias qhov piv ntawm kev co 5 txog 10 npaug siab dua li granite ntuj, nyob ntawm qhov piv ntawm resin-rau-aggregate.
Los ntawm qhov sib piv, cov khoom siv av nplaum muaj qhov tsis zoo ntawm kev co - feem ntau tsuas yog 0.01-0.02 qhov piv ntawm kev co, piv rau granite 0.03-0.05 thiab cov khoom siv hauv av 0.04-0.08.
Cov ntsiab lus tseem ceeb: Yog tias koj daim ntawv thov cuam tshuam nrog cov pawg sib pauv ceev ceev - zoo li lub tshuab hluav taws xob linear-driven PCB lossis semiconductor bonder - mineral casting tej zaum yuav yog qhov kev xaiv zoo tshaj plaws rau kev txo lub sijhawm settling. Yog tias koj tab tom tsim cov khoom siv kuaj mob ultra-precision, CMMs, lossis optical measurement platforms qhov twg dimensional stability dhau xyoo tseem ceeb dua li damping thaum txiav, solid granite tseem yog cov khoom siv nyiam.
Kev Yooj Yim Rau Kev Tsim Khoom Thiab Kev Tsim Qauv
Qhov no yog qhov uas peb yam khoom sib txawv tshaj plaws.
Granite raug rho tawm thiab tom qab ntawd zom kom zoo. Txawm hais tias nws ua tiav qhov tiaj tiaj siab tshaj plaws - ZHHIMG® ua granite mus rau nanometer-level flatness - nws nyuaj rau kev koom ua ke cov yam ntxwv sab hauv nyuaj. Ntxiv cov threaded inserts lossis coolant channels xav tau kev siv zog ntau thiab kev sib txuas. Peb lub peev xwm los ua cov khoom ib daim txog li 20 meters ntev, 4000mm dav, thiab 1000mm tuab - siv plaub lub tshuab sib tsoo Nantec loj heev, txhua tus nqi ntau dua $ 500,000 USD - qhia txog qhov ntsuas uas ua tau nrog granite ntuj.
Kev ua cov pob zeb hauv av yog ib txoj kev ua cov pob zeb. Qhov no tso cai rau "kev tsim ua ke": cov xov hlau, cov kav dej, thiab cov kav dej cable tuaj yeem raug pov ncaj qha rau hauv cov qauv. Cov neeg tsim qauv tuaj yeem tsim cov qauv khoob lossis cov khoom siv ribbed uas tsis yooj yim sua kom siv cov pob zeb khov kho. Los ntawm kev ua ntau qhov rau hauv ib lub hauv paus monolithic, koj txo cov lej ntawm cov pob qij txha bolted - ntxiv kev txhim kho tag nrho cov tshuab rigidity.
Cov khoom siv ua los ntawm av nplaum muaj qhov nyuaj tshaj plaws (Mohs 8–9.5) thiab tiv taus kev hnav, tab sis kev tsim khoom xav tau kev sib tsoo pob zeb diamond tshwj xeeb thiab kev sib xyaw ua ke kub siab tshaj 1200 ° C. Cov khoom siv ua los ntawm av nplaum feem ntau muaj qhov loj me thiab kim dua.
Qhov Kev Txiav Txim
Tsis muaj ib lo lus teb uas haum rau txhua tus. Cov chaw tsim khoom siv loj feem ntau siv tag nrho peb yam khoom, phim rau daim ntawv thov es tsis xaiv ib qho ua tus qauv dav dav:
- Xaiv cov granite ntuj rau cov platforms metrology, CMM bases, air-bearing surfaces, thiab optical benches qhov twg microns ntawm drift tshaj kaum xyoo yog qhov koj tab tom sim tiv thaiv.
- Xaiv cov khoom siv hlau casting rau cov thav duab cuab yeej tshuab thiab cov qauv uas yuav tsum tau muab pov rau hauv cov duab nyuaj thiab nqus tau qhov kev co ntawm kev txiav.
- Xaiv cov khoom siv ceramic rau cov ntawv thov uas xav tau qhov nyuaj heev, tiv taus kev hnav, lossis kev faib tawm sai sai hauv cov qauv me me.
Ntawm ZHHIMG®, peb tsim peb yam khoom - granite precision, ceramic precision, thiab mineral casting - vim peb tsis ntseeg tias yuav muaj ib qho kev daws teeb meem uas haum rau txhua yam. Peb cov granite dub ZHHIMG®, nrog nws qhov ceev 3100 kg / m³ thiab cov khoom zoo dua, tseem yog qhov ntsuas rau cov ntawv thov uas qhov kev ruaj khov tag nrho tsis tuaj yeem sib tham tau. Tab sis peb kuj paub tias mineral casting thiab ceramics muaj lawv qhov chaw hauv lub ecosystem precision. Qhov tseem ceeb yog paub tias cov khoom siv twg daws koj qhov teeb meem tshwj xeeb.
