Hauv lub ntiaj teb ntawm kev tsim kho kom raug heev, "qhov tseeb" ntawm kev ntsuas tsuas yog ntseeg tau raws li qhov chaw uas nws nyob rau. Txawm tias koj tab tom tsim lub cuab yeej tshuaj xyuas semiconductor ceev ceev lossis teeb tsa lub chaw kuaj mob laser cuam tshuam, kev xaiv koj cov khoom siv hauv paus - granite ntuj, epoxy-granite (mineral casting), lossis lub rooj kho qhov muag honeycomb - yog qhov kev txiav txim siab tseem ceeb tshaj plaws hauv theem tsim.
Ntawm ZHHIMG, peb ntseeg tias kev nkag siab txog kev sib pauv khoom siv thiab thermal ntawm cov ntaub ntawv no yog qhov tseem ceeb rau cov engineers thoob ntiaj teb uas xav ua kom tiav qhov rov ua dua sub-micron. Phau ntawv qhia no muab kev piav qhia txog kev sib piv ntawm cov hauv paus no thiab yuav ua li cas cais lawv ntawm kev co ntawm lub hauv pem teb niaj hnub.
Granite Ntuj vs. Epoxy-Granite: Kev Sib Cav Txog Kev Damping
Qhov kev sib tshuam feem ntau rau cov neeg tsim tshuab yog kev txiav txim siab ntawm qhov ruaj khov ntawm cov pob zeb ntuj thiab qhov yooj ywm ntawm cov khoom sib xyaw.
Granite Ntuj (Tus Qauv Kub): Granite dub ntuj, xws li Jinan Dub, tsis muaj qhov sib piv hauv nws qhov ruaj khov ntev. Vim tias nws tau "seasoned" hauv ntiaj teb rau ntau lab xyoo, nws tsis muaj kev ntxhov siab sab hauv. Hauv cov ntawv thov siab, granite ntuj yog qhov nyiam rau nws lub peev xwm los lapped rau qhov siab heev (Qib 00 lossis zoo dua). Nws qhov zoo tshaj plaws yog nws txoj kev tiv thaiv rau "creep" - qhov qeeb deformation ntawm cov khoom siv hauv qab load - ua rau nws yog qhov kev xaiv tseem ceeb rau CMM bases thiab air-bearing guideways.
Epoxy-Granite (Tus Kws Tshwj Xeeb Txog Kev Ua Kom Ntswg): Kuj tseem hu ua cov khoom siv ua los ntawm cov pob zeb hauv av lossis cov pob zeb polymer, epoxy-granite yog cov khoom sib xyaw ua ke ntawm cov pob zeb granite thiab epoxy resin. Nws qhov tshwj xeeb tshaj plaws yog nws cov coefficient ua kom ntub dej, uas yog kwv yees li 3 txog 10 npaug ntau dua li cov granite ntuj thiab 30 npaug zoo dua li hlau.
Txawm hais tias epoxy-granite tsis tuaj yeem raug lapped rau tib qho kev kam rau siab zoo li pob zeb ntuj (nws feem ntau xav tau cov granite ntuj lossis hlau ntxig rau qhov tseeb precision nto), nws yog qhov kev xaiv zoo dua rau cov tshuab CNC ceev ceev qhov twg "chatter" thiab lub cev muaj zog ua rau resonance yuav tsum tau tshem tawm tam sim ntawd. Ntxiv mus, cov txheej txheem casting tso cai rau cov geometries sab hauv nyuaj, xws li cov dej txias thiab cov hlau conduits, kom koom ua ke ncaj qha rau hauv lub hauv paus.
Cov Rooj Teeb Pom Kev Zoo vs. Cov Hauv Paus Granite: Cov Khoom Siv Static vs. Kev Rho Tawm Dynamic
Ib qho kev nkag siab yuam kev hauv chav kuaj mob yog tias lub rooj teeb pom kev zoo thiab lub phaj granite saum npoo tuaj yeem sib pauv tau. Qhov tseeb, lawv tau tsim los daws ob qho teeb meem sib txawv.
Lub Tshuab Granite siv nws qhov hnyav loj (qhov hnyav siab) thiab qhov tawv tawv kom tiv taus kev txav mus los. Nws yog ib qho kev daws teeb meem "static". Nws zoo tagnrho rau kev teeb tsa cov khoom siv kho tshuab hnyav, xws li cov cav linear thiab cov gantries loj, qhov twg qhov tiaj tiaj ntawm qhov chaw yog qhov tseem ceeb datum.
Ib lub Rooj Optical, los ntawm qhov sib piv, feem ntau siv cov qauv sandwich honeycomb stainless-steel. Nws yog tsim los kom sib dua tab sis khov kho, nrog lub hom phiaj tshwj xeeb ntawm kev tswj hwm kev co dynamic. Cov rooj Optical tau ua kom zoo rau kev rho tawm zaus siab thiab kev sib npaug thermal. Vim tias lawv muaj peev xwm cua sov qis dua li lub pob zeb loj, lawv mus txog qhov sib npaug thermal nrog chav sai dua - qhov tseem ceeb rau kev sim laser qhov twg 0.1 ° C hloov pauv tuaj yeem ua rau lub teeb poob.
Txawm li cas los xij, rau kev ntsuas kev lag luam, lub rooj teeb pom kev feem ntau tsis muaj qhov tawv ntawm qhov chaw thiab qhov tiaj tiaj ntev uas xav tau los txhawb cov khoom siv txav mus los. Yog tias koj daim ntawv thov cuam tshuam nrog tus choj txav mus los hnyav, qhov ruaj khov ntawm ZHHIMG granite puag tseem yog qhov kev xaiv thawj zaug ntawm kev lag luam.
Kev Tshawb Fawb Txog Kev Ntshai: Hom Kev Rho Tawm Kev Co
Txawm tias lub hauv paus granite zoo tshaj plaws los kuj tseem raug cuam tshuam los ntawm lub suab nrov ntawm av qeeg ntawm lub Hoobkas - forklifts, HVAC systems, thiab cov tshuab hnyav nyob ze. Txhawm rau tiv thaiv koj qhov kev ua haujlwm raug, koj yuav tsum xaiv lub kaw lus cais tawm uas tsim nyog.
1. Cov Khoom Siv Elastomeric Passive: Cov kev daws teeb meem yooj yim tshaj plaws thiab pheej yig tshaj plaws, cov no yog cov roj hmab zoo lossis silicone mounts muab tso rau hauv qab lub hauv paus granite. Lawv zoo heev rau kev co zaus siab tab sis muaj teeb meem nrog lub suab nrov qis. Lawv feem ntau siv rau cov chaw soj ntsuam txheem.
2. Kev Rho Tawm Cua Tsis Siv Neeg (Pneumatic): Cov kab ke no siv "cov cua caij nplooj ntoos hlav" los ua kom lub hauv paus granite ntab rau ntawm lub hauv ncoo cua. Los ntawm kev sib cais lub hauv paus ntawm hauv pem teb, cov kab ke pneumatic tuaj yeem ua tiav qhov zaus ntuj tsawg li 2Hz. Qhov no yog qhov kev teeb tsa tus qauv rau Coordinate Measuring Machines (CMMs) thiab optical microscopes.
3. Kev Tshem Tawm Kev Cob Qhia: Rau cov ntawv thov uas xav tau ntau tshaj plaws, xws li kev luam theej duab lossis kev tshawb fawb nanotechnological, cov txheej txheem passive tsis txaus. Cov txheej txheem nquag siv cov sensors (accelerometers) thiab actuators los "tawm tsam" kev co tuaj rau lub sijhawm tiag tiag. Yog tias hauv pem teb txav mus rau saum toj, tus actuator txav lub hauv paus nrog lub zog sib npaug, ua rau "khov" lub granite hauv qhov chaw.
Tsim Koj Lub Hauv Paus nrog ZHHIMG
Kev xaiv cov khoom siv zoo yog qhov sib npaug ntawm qhov tseeb, kev ntub dej, thiab cov yam ntxwv ib puag ncig. Ntawm ZHHIMG, peb tshwj xeeb hauv kev txuas qhov sib txawv ntawm pob zeb ntuj thiab kev tsim kho tshuab niaj hnub.
Peb muab cov hauv paus granite ntuj tsim tshwj xeeb rau cov neeg uas xav tau qhov tseeb tshaj plaws, thiab peb muab cov kev daws teeb meem sib xyaw ua ke uas sib xyaw cov txiaj ntsig ntawm kev co thiab damping ntawm cov mineral casting qhov twg tsim nyog. Los ntawm kev sib txuas cov hauv paus no nrog cov thev naus laus zis cais tawm kom raug, peb xyuas kom meej tias koj lub tshuab ua haujlwm tsuas yog txwv los ntawm nws tus qauv tsim, tsis yog nws ib puag ncig.
Thaum qhov kev xav tau ntawm qhov tseeb txav mus rau qhov ntsuas nanometer, koj lub hauv paus tsis yog tsuas yog kev txhawb nqa xwb - nws yog ib feem tseem ceeb ntawm txoj saw ntsuas.
