Nyob rau hauv lub ntiaj teb no ntawm hnyav manufacturing, qhov twg Cheebtsam yuav hnyav ob peb tons thiab dimensional kam rau ua yog ntsuas nyob rau hauv microns, lub hauv paus ntawm machining thiab soj ntsuam ua hauj lwm yog ib qho tseem ceeb raws li lub tshuab nws tus kheej. Cam khwb cia hlau nto platforms tau tshwm sim raws li tus qauv kev lag luam rau precision workholding, muab ib tug tshwj xeeb ua ke ntawm cov khoom siv uas ncaj qha daws cov teeb meem tsis tu ncua nyob rau hauv hnyav machining ua hauj lwm. Los ntawm kev tsim hluav taws xob hauv tsheb mus rau kev tsim cov khoom siv dav hlau, cov precision- engineering platforms muab qhov chaw ruaj khov, tiaj tus siv qhov chaw tseem ceeb rau kev tswj xyuas qhov tseeb tshaj qhov xav tau ntawm kev lag luam niaj hnub no.
Cov Kev Sib Tw Tshwj Xeeb ntawm Heavy Machining Ib puag ncig
Heavy machining kev ua haujlwm nthuav tawm cov txheej txheem tshwj xeeb ntawm cov kev sib tw uas sib txawv ntawm cov khoom siv niaj hnub. Thaum ua hauj lwm nrog loj castings, forged Cheebtsam, los yog welded lug hnyav los ntawm pua pua mus rau phav phav kilograms, txawm me me deflections nyob rau hauv lub chaw ua hauj lwm nto tuaj yeem qhia qhov loj me me yuam kev. Cov rog tsim tawm thaum lub sij hawm milling, tho txawv, thiab sib tsoo ua haujlwm- feem ntau ntsuas hauv tons ntawm txiav quab yuam- tsim kev vibrations uas yuav tsum tau absorbed thiab dissipated kom tswj tau txiav precision. Tsis tas li ntawd, qhov sib txawv ntawm qhov kub thiab txias ntawm cov chaw tsim khoom, xws li kev hloov pauv raws caij nyoog mus rau cov cua sov tsim los ntawm cov txheej txheem machining nws tus kheej, ua rau thermal expansion uas tuaj yeem cuam tshuam qhov ntsuas qhov tseeb.
Cov tsoos hlau lossis granite ua haujlwm qhov chaw, thaum tsim nyog rau ntau daim ntawv thov, ntsib kev txwv nyob rau hauv qhov hnyav machining scenarios. Cov rooj hlau, txawm tias lawv lub zog, muaj kev tiv thaiv corrosion thiab yuav tsum tau saib xyuas tas li los tiv thaiv qhov degradation. Granite nto muaj kev ruaj ntseg zoo heev tab sis tuaj yeem nkig thiab tuaj yeem tawg hauv kev poob siab lossis tsis sib npaug ntawm qhov hnyav. Tsis tas li ntawd, granite qhov qis thermal conductivity txhais tau hais tias nws teb qeeb dua rau kev hloov pauv kub, uas ua rau muaj kev ntsuas tsis meej thaum lub sijhawm hloov ntawm ib puag ncig. Cov kev cov nyom no tau nthuav dav hauv qhov chaw tsim khoom uas 24/7 kev ua haujlwm thiab kev thauj mus los tsis tu ncua yog tus qauv, ua rau kev xaiv cov khoom siv thiab lub platform tsim cov ntsiab lus tseem ceeb hauv kev tswj xyuas lub sijhawm ntev -.
Cov khoom zoo ntawm Cast Iron Precision Platforms
High - zoo cam khwb cia hlau nto platforms, feem ntau yog tsim los ntawm HT200 rau HT300 qib grey hlau raws li GB/T 9439 tus qauv, muab ib tug txaus kev daws rau cov teeb meem machining hnyav. Cov khoom siv graphite microstructure muab cov khoom muaj txiaj ntsig zoo uas nqus thiab dissipate vibration generated thaum lub sij hawm machining, txo kev sib tham thiab txhim kho nto tiav. Kev soj ntsuam ywj pheej tau pom tias cov hlau cam khwb cia hlau tuaj yeem txo qis kev sib kis tau txog li 40% piv rau cov qauv hlau sib npaug, txhais ncaj qha rau kev txhim kho lub neej thiab qhov sib xws.
Cov qauv tsim ntawm niaj hnub cam khwb cia hlau platforms ntxiv txhim khu lawv kev ua tau zoo nyob rau hauv hnyav load scenarios.

Lub 16 lossis ntau dua cov ntsiab lus sib cuag ntawm 200mm square thiab nto roughness ntawm Ra 1.6μm muab cov ntaub ntawv raug tsim nyog rau kev ntsuas qhov tseem ceeb thiab siab -kev ua haujlwm sib dhos.
Rau kev siv hauv pem teb ntau lawm, Qib 1 platforms muaj qhov sib npaug zoo ntawm qhov tseeb thiab kav ntev. Nrog flatness kam rau ua ntawm kwv yees li 0.03mm rau 1000mm × 1000mm platform thiab yam tsawg kawg nkaus 12 lub ntsiab lus ntawm ib 200mm square, cov platforms no feem ntau soj ntsuam, layout, thiab sib dhos ua hauj lwm nyob rau hauv dav machinery manufacturing, tsim khoom siv, thiab ua liaj ua teb machinery chaw. Lub zog ntawm Qib 1 platforms ua rau lawv zoo tshwj xeeb tshaj yog- haum rau ib puag ncig uas cov platforms pom kev siv niaj hnub txuas ntxiv hla ntau qhov kev hloov pauv ntau lawm.
Qib 2 thiab 3 platforms tsom rau kev thauj khoom muaj peev xwm thiab cov qauv rigidity thaum tswj xyuas qhov tseeb qhov tseeb rau kev sib dhos hnyav thiab kev ua haujlwm tsis zoo. Qib 2 platforms, nrog flatness kam rau ua nyob ib ncig ntawm 0.06mm rau cov qauv ntau thiab tsawg, ua hauj lwm raws li cov chaw ua hauj lwm rau kev sib koom ua ke, vuam fixturing, thiab dav layout ua hauj lwm. Qib 3 platforms, qhov kev xaiv muaj zog tshaj plaws nrog kev ua siab ntev ntawm kwv yees li 0.12mm, muab qhov hnyav - lub hauv paus tsim nyog rau cov qauv hlau loj sib dhos, cov khoom siv hnyav disassembly thiab rov sib sau ua ke, thiab raws li qib hauv paus rau cov tshuab tsim khoom loj.
Nto Npaj Technology
Lub precision ua tiav los ntawm cam khwb cia hlau platforms nyob ntawm qhov chaw npaj cov txheej txheem ua haujlwm thaum tsim khoom. Tes scraping, cov txheej txheem ib txwm tseem nyiam rau cov ntawv thov precision siab tshaj plaws, suav nrog kev tshem tawm cov khoom siv cov cuab yeej siv tes los tsim cov yam ntxwv ntawm cov ntsiab lus sib cuag thoob plaws lub platform. Rau Qib 0 thiab Qib 1 platforms, cov txheej txheem no tsim qhov tsawg kawg nkaus ntawm 25 cov ntsiab lus tiv tauj ib 25mm square, muab cov khoom zoo tshaj plaws wringing thiab qhov ruaj khov ntawm qhov ntsuas qhov ntsuas qhov tseeb.
Cov txheej txheem kev tsim khoom niaj hnub ua kom tiav tes scraping nrog precision npaj thiab kev sib tsoo ua haujlwm uas ua tiav qhov roughness qhov tseem ceeb tsawg li Ra 3.2μm rau kev tsim khoom- qib platforms. Cov txheej txheem mechanized no, thaum tswj tau zoo, xa cov khoom zoo ib yam thoob plaws lub platform loj txog li 8000mm × 3000mm thiab tshaj. Kev sib xyaw ua ke ntawm precision machining thiab cov kws tshaj lij tes ua tiav tsim cov hybrid nto uas sib npaug ntawm kev ua haujlwm zoo nrog kev ua haujlwm metrological, ua rau niaj hnub cam khwb cia hlau platforms haum rau cov kev xav tau tshaj plaws hauv kev lag luam.
Ntau lub platforms tseem muaj cov kev hloov kho saum npoo tshwj xeeb raws li kev thov tshwj xeeb. T-slots, V-grooves, tapped qhov, thiab nrhiav daim phiaj tuaj yeem sib xyaw ncaj qha rau hauv lub platform qauv, muab ntau yam kev ua haujlwm muaj peev xwm yam tsis muaj kev cuam tshuam rau qhov kev ntseeg ntawm qhov chaw. Cov kev sib xyaw ua ke no tshem tawm qhov xav tau ntawm cov khoom sib cais uas tuaj yeem ua kom paub cov kev sib raug zoo, ua kom cov txheej txheem ntau lawm thiab txo lub sijhawm teeb tsa rau kev rov ua haujlwm machining.
Kev siv cov txiaj ntsig hauv kev tsim khoom hnyav
Kev txais yuav ntawm precision cam khwb cia hlau platforms muab ntsuas kev ua haujlwm thiab cov txiaj ntsig zoo thoob plaws kev tsim khoom hnyav. Cov cuab yeej txuas ntxiv lub neej, ua rau txo qis kev vibration thiab txhim kho kev ruaj ntseg, ncaj qha txo cov nqi tsim khoom thiab txhim kho machining sib xws. Ib lub tuam txhab tsim khoom loj tshaj plaws tau tshaj tawm txog 22% txo cov nqi siv nyob rau hauv rau lub hlis ntawm kev txhim kho lawv cov chaw ua haujlwm machining 'chaw ua hauj lwm platforms rau precision cam khwb cia hlau units, attributing qhov kev txhim kho kom txo chatter thiab txhim kho tej yam kev mob.
Cov kev pabcuam kev lees paub zoo kuj tau txais txiaj ntsig zoo los ntawm kev siv ruaj khov los ntawm cov hlau cam khwb cia. Cov ntaub ntawv zoo sib xws txo qis kev ntsuas qhov tsis paub tseeb thaum lub sijhawm kuaj xyuas, hauv - kev txheeb xyuas cov txheej txheem, thiab kev kuaj xyuas zaum kawg, ua rau tsawg dua qhov tsis lees paub thiab txo nqi rov ua haujlwm dua. Hauv kev tsim lub cav tsheb, qhov twg lub tog raj kheej bore alignment thiab crankshaft bore concentricity yog qhov tseem ceeb ntawm kev ua tau zoo, cov chaw siv qib 0 cam khwb cia hlau tshuaj xyuas platforms tau tshaj tawm txog li 18% txo qis hauv qhov tsis sib xws - piv rau cov chaw siv lwm qhov chaw ua haujlwm.
Qhov ntev - lub sij hawm ua haujlwm ntev ntawm cov hlau cam khwb cia yog lwm qhov txiaj ntsig kev lag luam. Tsis zoo li cov chaw uas degrade dhau kev kho tom qab siv ntau xyoo, cam khwb cia hlau platforms tuaj yeem rov ua dua thiab rov ua dua -calibrated ntau zaus, ua haujlwm tau zoo rau lawv lub neej kev pab mus tas li nrog kev saib xyuas kom raug. Qhov kev kho dua tshiab no ua rau cov hlau cam khwb cia ntev - lub sij hawm peev peev ntau dua li cov cuab yeej siv tau, muab ntau xyoo ntawm kev pabcuam txhim khu kev qha nrog kev saib xyuas kev ua haujlwm ntev.
Xaus
