Hauv kev tsim khoom kom raug, qhov kev ncaj ncees thiab qhov tseeb ntawm cov cuab yeej ntsuas yog qhov tseem ceeb rau kev ua kom zoo ntawm cov khoom kawg. Cov platform granite, feem ntau siv ua lub hauv paus rau cov tshuab ntsuas sib koom ua ke (CMMs), cov cuab yeej tshuaj xyuas, thiab ntau yam kev teeb tsa machining, yuav tsum tswj lawv qhov tseeb nyob rau hauv ntau yam kev mob hnyav. Lub peev xwm thauj khoom ntawm cov platforms no tsis yog ib qho loj-haum-txhua qhov kev qhia tshwj xeeb, vim tias cov platforms tau tsim los ua kom tau raws li cov kev cai tshwj xeeb raws li qhov hnyav uas lawv xav tias yuav dais. Los ntawm cov qauv sib dua mus rau cov kev daws teeb meem hnyav, kev nkag siab txog qhov sib txawv ntawm kev tsim qauv hauv cov platforms granite yog qhov tseem ceeb rau kev ua kom lawv ua tau zoo tshaj plaws hauv cov ntawv thov kev lag luam sib txawv.
Cov platform granite yog qhov tseem ceeb rau kev muab qhov chaw ruaj khov, thiab lawv lub peev xwm thauj khoom yog qhov tseem ceeb hauv kev tswj kom tiaj tus thiab txo qhov deformation thaum siv. Cov platform no yuav tsum tau tsim thiab tsim nrog cov ntaub ntawv, cov qauv, thiab cov txheej txheem ua haujlwm uas phim nrog lawv cov ntawv thov. Txawm hais tias lub platform txhawb nqa cov khoom sib dua lossis cov tshuab hnyav, nws yog qhov tseem ceeb rau kev xaiv tus qauv tsim kom ntseeg tau tias muaj qhov tseeb mus sij hawm ntev.
Rau cov platform granite uas tsis hnyav heev, feem ntau yog cov uas tsis hnyav tshaj 500 kg, tus qauv no siv qhov sib npaug ntawm qhov raug siab thiab qhov sib npaug ntawm kev tsim kho uas tsis hnyav heev. Cov platform no feem ntau siv rau hauv cov chaw uas xav tau qhov raug siab, tab sis qhov hnyav ntawm lub platform yuav tsum tau txo qis. Cov ntaub ntawv zoo li cov pob zeb dub mica zoo, nrog cov ntsiab lus quartz ntawm 30% lossis ntau dua, feem ntau siv. Cov khoom siv no muaj qhov ceev zoo tshaj plaws ntawm 2.6–2.7g/cm², ua kom muaj kev ruaj khov thaum txo qhov hnyav. Lub platform qhov tuab feem ntau yog ntawm 50 thiab 80 hli rau tus qauv 1m × 1m, thiab tus qauv no muaj cov qauv ribbed hollow nyob rau hauv qab. Nrog cov ribs sib nrug 200–300mm thiab muaj qhov dav ntawm 30mm thiab qhov siab ntawm 40mm, tus qauv no muab qhov sib npaug zoo tagnrho ntawm lub zog thiab qhov hnyav txo qis, ua rau nws sib dua 30% dua li cov qauv khov kho. Tsis tas li ntawd, lub platform qhov zaus resonance yog siab dua 50Hz, uas pab tiv thaiv kev cuam tshuam los ntawm kev co.
Qhov kev tsim qauv meej rau cov platforms no kuj yog qhov tseem ceeb. Qhov tiaj tiaj ntawm qhov chaw ua haujlwm feem ntau raug tswj kom tsawg dua 0.005mm / 100mm, ua kom muaj kev hloov pauv tsawg kawg nkaus txawm tias nyob rau hauv cov khoom thauj nruab nrab.cov platform granitefeem ntau siv rau kev sib dhos cov cuab yeej kho qhov muag, kev ntsuas cov cuab yeej me me, thiab cov ntawv thov zoo sib xws uas kev sib cuag nrog lub platform suav rau ntau dua 60% ntawm tag nrho thaj chaw bearing, tiv thaiv kev siab dhau ntawm cov ntsiab lus hauv zos.
Cov platforms nruab nrab, txij li 500 kg txog 5000 kg, yog tsim los nrog ntau yam kev xav tau sib txawv. Thaum tswj hwm qib siab ntawm kev raug, cov platforms no yuav tsum tau txais cov khoom loj dua. Rau cov platforms no, cov granite nruab nrab yog qhov zoo dua, feem ntau nrog cov ntsiab lus feldspar ntawm 40% -50%. Qhov ceev tau nce mus txog 2.7-2.8g / cm³, thiab lub platform qhov tuab tau tsa mus txog 100-150mm rau tus qauv 1m × 2m. Sab hauv qab muaj cov qauv grid-reinforced, qhov twg cov tav tseem ceeb yog 50mm dav, thiab cov tav hla yog 30mm dav, tsim ib daim phiaj 100 × 100mm. Cov ntsiab lus ntxhov siab tau puag ncig ntawm cov ces kaum kom txo qhov concentration. Cov qauv grid no ua kom lub platform tswj hwm nws lub zog thiab txo qis kev khoov.
Rau qhov tseeb ntxiv, cov platforms no feem ntau muaj T-slots (12–16mm dav) rau kev teeb tsa fixture, nrog rau qhov sib nrug ntawm 100mm txog 150mm. Cov qhov tau teeb tsa kom tiv thaiv kev ua kom lub platform lub zog tsis muaj zog, nrog qhov tsawg kawg nkaus ntawm 30mm ntawm sab hauv qab. Thaum lub sijhawm teeb tsa, cov kev txhawb nqa kho tau siv los faib cov khoom thauj kom sib npaug, nrog plaub qhov chaw txhawb nqa ib square meter, kom ntseeg tau tias qhov sib txawv ntawm cov khoom thauj tseem nyob hauv 5%. Cov platforms no feem ntau siv rau hauv cov tshuab ntsuas kev sib koom tes, kev tshuaj xyuas pwm nruab nrab, thiab cov ntawv thov zoo sib xws, qhov twg qhov siab tshaj plaws tso cai deflection yog ≤ L / 10000 (L yog qhov ntev ntawm lub platform).
Cov platforms hnyav, tsim los rau cov khoom thauj ntau tshaj 5000 kg, yog tsim los tiv thaiv kev hloov pauv hauv qab qhov hnyav loj. Cov platforms no yog ua los ntawm cov granite ntxhib, nrog cov siv lead ua quartz loj dua 2 hli, thiab muaj qhov ceev tshaj 2.8g / cm³. Lub zog compressive ntawm cov khoom siv no feem ntau yog tshaj 200 MPa, thiab qhov tuab ntawm cov platforms no yog txij li 200 txog 300 hli rau tus qauv 2m × 3m. Cov qauv yog khov kho, nrog lub hauv paus tuab (tuab 50 hli) uas txuas rau lub platform tseem ceeb los ntawm lub hauv paus zoo li qe nrog cov epoxy resin bonding (nrog lub zog shear ≥ 15 MPa).
Rau cov platforms hnyav, kev teeb tsa yuav tsum tau npaj av tshwj xeeb. Lub hauv paus pob zeb yuav tsum muaj tsawg kawg yog 300 hli tuab, nrog rau cov hlau phaj ua los ntawm cov khoom siv Q235. Nruab nrab ntawm lub hauv paus thiab lub platform, ib txheej roj hmab chloroprene tuab 3 hli siv los xyuas kom meej tias muaj kev faib tawm kev ntxhov siab sib npaug. Lub hauv paus yuav tsum muaj peev xwm nqa khoom tsawg kawg yog 0.3 MPa. Cov platforms no yog siv rau hauv cov ntawv thov xws li kev tshuaj xyuas cov cuab yeej siv tshuab hnyav thiab kev teeb tsa casting loj, qhov twg kev hloov pauv mus sij hawm ntev yuav tsum nyob qis dua 0.002 hli ib xyoos.
Cov qauv kev xeem rau cov platform granite sib txawv uas muaj peev xwm thauj khoom kuj sib txawv heev. Cov platform sib dua raug kuaj kev co (10-500Hz sweep frequency, amplitude 0.1mm) kom paub tseeb tias tsis muaj resonance tshwm sim. Cov platforms nruab nrab raug kuaj xyuas qhov static load ntawm 1.2 npaug ntawm lawv lub peev xwm ntsuas, nrog rau deformation tsis pub tshaj 0.001mm tom qab 24 teev ntawm kev siv thiab tshem tawm. Cov platforms hnyav raug kuaj xyuas rau kev tiv thaiv kev qaug zog, nrog 1000 lub voj voog thauj khoom-tso tawm ntawm 80% ntawm lawv cov khoom ntsuas kom paub tseeb tias tsis muaj kab nrib pleb tshwm sim, txheeb xyuas los ntawm kev kuaj pom qhov tsis zoo nkag mus.
Thaum xaiv lub platform granite zoo, nws yog ib qho tseem ceeb kom phim tus qauv tsim rau cov kev xav tau tshwj xeeb ntawm daim ntawv thov. Rau cov lag luam uas xav tau kev ua haujlwm siab thiab muaj peev xwm thauj khoom hnyav, kev xaiv tus qauv tsim platform kom raug ua kom muaj kev ua haujlwm ntev thiab kev ntseeg siab. ZHHIMG nkag siab txog qhov tseem ceeb ntawm cov kev daws teeb meem tshwj xeeb uas tsim los ua kom tau raws li cov kev xav tau tshwj xeeb ntawm txhua tus neeg siv khoom, muab ntau yam granite platforms uas muab kev ua haujlwm zoo dua, kev ruaj khov, thiab kev ua haujlwm ntev hauv ntau yam kev thauj khoom.
