Kev ncaj ncees ntawm txhua qhov kev tsim khoom los yog cov txheej txheem metrology pib nrog nws lub hauv paus. Ntawm ZHHIMG®, thaum peb lub koob npe nrov yog tsim los ntawm Ultra-Precision Granite cov kev daws teeb meem, peb paub txog lub luag haujlwm tseem ceeb uas Cast Iron Surface Phaj thiab Marking Phaj ua si thoob plaws ntiaj teb kev lag luam. Kev nkag siab yuav ua li cas rau nruab, tswj, thiab txheeb xyuas qhov tseeb ntawm cov cuab yeej siv no tsis yog qhov kev coj ua zoo tshaj plaws - nws yog qhov sib txawv ntawm kev ruaj ntseg zoo thiab cov khoom siv kim heev.
Yam yuavtsum tau kawm uantej: Txhim kho kom zoo thiab tsis muaj kev cuam tshuam
Ua ntej lub cam khwb cia hlau npav tuaj yeem xa nws cov ntaub ntawv raug, nws yuav tsum raug ntsia thiab kho kom raug. Qhov kev teeb tsa tseem ceeb no tsis yog txheej txheem xwb; nws ncaj qha cuam tshuam rau lub phaj txoj kev ncaj ncees thiab flatness. Kev teeb tsa tsis raug-xws li kev faib khoom tsis sib xws lossis tsis raug theem- tuaj yeem ua txhaum txoj cai kev lag luam thiab ua rau lub phaj tsis zoo, ua rau nws siv tsis tau. Yog li ntawd, tsuas yog tso cai, cov neeg ua haujlwm tau txais kev cob qhia yuav tsum ua txoj haujlwm no. Ua txhaum cov txheej txheem no tsis yog tsuas yog tsis ua raws cai tab sis kuj tuaj yeem cuam tshuam cov qauv ntawm cov cuab yeej precision.
Kos Daim Hlau hauv Kev Ua Haujlwm: Cov Ntaub Ntawv Siv
Hauv ib qho kev cob qhia, cov cuab yeej raug faib rau cov luag haujlwm tshwj xeeb: siv, ntsuas, kos duab ncaj qha, thiab clamping. Daim ntawv cim npe yog cov cuab yeej siv tseem ceeb rau kev sau ntawv. Scribing nws tus kheej yog qhov tseem ceeb ntawm kev txhais cov duab kos rau ntawm qhov khoob lossis ib nrab ua tiav workpiece, tsim kom muaj cov ciam teb ua tiav, cov ntsiab lus siv, thiab cov kab kho qhov tseem ceeb. Qhov no yog thawj zaug scribing raug, feem ntau xav kom nyob rau hauv 0.25 hli mus rau 0.5mm, muaj ib tug ncaj qha thiab muaj kev cuam tshuam rau qhov kawg khoom zoo.
Yuav kom tswj tau qhov kev ncaj ncees no, lub phaj yuav tsum tau muab tso rau hauv theem thiab ruaj ntseg, nrog rau cov khoom sib npaug sib npaug thoob plaws txhua qhov kev txhawb nqa kom tsis txhob muaj kev ntxhov siab. Cov neeg siv yuav tsum xyuas kom meej tias qhov hnyav ntawm lub workpiece yuav tsum tsis txhob dhau ntawm lub phaj qhov ntsuas kom tiv thaiv kev puas tsuaj, deformation, thiab txo qis hauv kev ua haujlwm zoo. Tsis tas li ntawd, qhov chaw ua haujlwm yuav tsum tau siv tsis tu ncua los tiv thaiv kev hnav thiab dents, ua kom lub neej ntev.
Tshawb xyuas Flatness: Science of Verification
Qhov tseeb ntsuas ntawm daim ntawv scribing yog qhov flatness ntawm nws ua hauj lwm nto. Thawj txoj hauv kev rau kev txheeb xyuas yog qhov Spot Method. Txoj kev no dictates qhov yuav tsum tau ceev ntawm kev sib cuag cov ntsiab lus nyob rau hauv ib tug 25mm square cheeb tsam:
- Qib 0 thiab 1 Phaj: Yam tsawg kawg 25 qhov chaw.
- Qib 2 Phaj: Yam tsawg kawg 20 qhov chaw.
- Qib 3 Phaj: Yam tsawg kawg 12 qhov chaw.
Thaum cov txheej txheem ib txwm siv ntawm "scraping ob daim hlau sib tw" yuav ua kom muaj kev sib haum xeeb thiab kev sib raug zoo ntawm qhov chaw, nws tsis tuaj yeem lav qhov flatness. Cov txheej txheem no tuaj yeem ua rau ob lub ntsej muag zoo kawg nkaus uas yog, qhov tseeb, spherically nkhaus. Qhov tseeb ncaj thiab flatness yuav tsum tau txheeb xyuas siv cov txheej txheem nruj dua. Straightness sib txawv tuaj yeem ntsuas tau los ntawm kev txav lub dial taw qhia thiab nws cov kev txhawb nqa sawv ntsug raws li kev paub ncaj nraim, xws li tus kav lub kaum sab xis, hla lub phaj saum npoo. Rau qhov xav tau tshaj plaws ntsuas daim phiaj, Optical Plane Method siv optical interferometry yog ua haujlwm los txheeb xyuas qhov tseeb ntawm qib sub-micron.
Kev kho qhov tsis zoo: Ua kom lub neej ntev thiab ua raws
Kev kos phaj zoo yog tswj hwm los ntawm kev tswj hwm nruj, xws li JB / T 7974-2000 tus qauv hauv kev lag luam tshuab. Thaum lub sij hawm casting txheej txheem, tsis xws luag xws li porosity, xuab zeb qhov, thiab shrinkage kab noj hniav tuaj yeem tshwm sim. Kev tuav tswj kom zoo ntawm cov kev tsis zoo no yog qhov tseem ceeb rau lub phaj lub neej ua haujlwm. Rau cov phaj uas muaj qhov tseeb qis dua "00", qee qhov kev kho tau tso cai:
- Me me tsis xws luag (xuab zeb hais nrog ib txoj kab uas hla tsawg tshaj li 15 hli) tuaj yeem txuas nrog tib yam khoom, muab lub ntsaws qhov hardness qis dua cov hlau ib puag ncig.
- Qhov chaw ua haujlwm yuav tsum tsis pub ntau tshaj plaub lub ntsiab lus txuas, sib cais los ntawm qhov deb tsawg kawg yog $ 80\text{mm}$.
Tshaj li qhov tsis zoo ntawm casting, qhov chaw ua hauj lwm yuav tsum tsis pub muaj kev siv los cuam tshuam xeb, khawb, lossis dents.
Kev Kho Kom Zoo Kawg Nkaus
Txawm hais tias cov cuab yeej siv yog Cast Iron Marking Plate lossis ZHHIMG® Granite Surface Phaj, kev saib xyuas yog qhov yooj yim tseem ceeb heev. Qhov saum npoo yuav tsum huv si; thaum tsis siv, nws yuav tsum tau muab ntxuav kom huv si thiab coated nrog cov roj tiv thaiv kev tiv thaiv xeb thiab npog nrog lub npog tiv thaiv. Kev siv yuav tsum tau ua nyob rau hauv ib puag ncig tswj, qhov zoo tshaj plaws ntawm qhov kub thiab txias ntawm (20 ± 5) ℃, thiab kev co yuav tsum nruj me ntsis zam. Los ntawm kev ua raws li cov lus qhia nruj me ntsis rau kev teeb tsa, siv, thiab kev saib xyuas, cov neeg tsim khoom tuaj yeem ua kom lawv cov dav hlau siv nyob hauv qhov tseeb, tiv thaiv qhov zoo thiab kev ncaj ncees ntawm lawv cov khoom kawg.
