Nyob rau hauv lub teb ntawm precision manufacturing, xyuas kom meej qhov zoo thiab precision ntawm ob -sab hauv av machining ntawm lub Cheebtsam relies hnyav rau systematic thiab kev ua tiav cov qauv.Cov qauv no tsis tsuas yog tswj cov cuab yeej kev ua tau zoo thiab cov txheej txheem tsis tab sis kuj qhia meej qhov ntev, geometric tolerances, nto zoo, thiab kev soj ntsuam cov txheej txheem ntawm lub hauv paus, muab cov txheej txheem kev ua tau zoo thiab cov txheej txheem. kev sib nrig kev paub. Raws li siab- cov cuab yeej kawg txuas ntxiv nce nws qhov yuav tsum tau ua rau qhov tseeb ntawm qhov tseeb thiab qhov tseeb ntawm qhov chaw, cov qauv kev ua tiav rau ob - cov khoom siv sab hauv av tau hloov zuj zus mus rau kev ua kom zoo dua qub, ua kom tiav, thiab ua haujlwm tau zoo.
Cov qauv kev ua haujlwm ua ntej npog cov kev xav tau ntawm cov khoom siv nws tus kheej. Cov txheej txheem cuam tshuam tau hais meej meej meej ntawm kev sib tsoo disc, radial thiab axial runout ntawm spindle, qhov tseeb ntawm cov lus tsa suab, thiab kev tswj qhov kub thiab txias ntawm ob -sab sib tsoo tshuab kom paub meej tias cov cuab yeej muaj cov txheej txheem yooj yim rau kev ua tiav micron - theem thiab txawm tias sub-}micron Piv txwv li, hais txog qhov flatness ntawm kev sib tsoo disc, siab - cov qauv precision yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm tag nrho cov lus qhia (TIR) tsis pub tshaj ob peb micrometers nyob rau hauv txoj kab uas hla zoo; spindle runout yuav tsum tau tswj nyob rau hauv ib qho me me ntau yam los tiv thaiv qhov kev taw qhia ntawm lub sij hawm yuam kev thaum lub sij hawm machining. Cov ntsuas no muab ntau lub hauv paus rau kev xaiv cov khoom siv, kev lees paub, thiab kev ntsuas lub sijhawm.
Hais txog qhov ua tau zoo ntawm cov khoom siv ua haujlwm, cov qauv qhia cov ncauj lus kom ntxaws txog qhov ntev ntev, flatness, parallelism, thiab nto roughness. Rau ntau hom ntawm cov khoom sib txawv, cov qauv faib cov kev zam raws li lawv daim ntawv thov thiab ib puag ncig kev pabcuam. Piv txwv li, valve daim hlau siv rau hydraulic seals muaj qhov yuav tsum tau muaj siab heev rau flatness thiab deg roughness, thaum cov txheej txheem kev txhawb nqa cov khoom tso cai rau cov xoob kam rau ua ntau yam. Kev cim thiab kev tshuaj xyuas ntawm cov khoom lag luam geometrical specifications (GPS) yuav tsum ua raws li cov txheej txheem los xyuas kom meej qhov sib piv thiab txoj cai ntawm kev ntsuas ntsuas. Nto roughness feem ntau yog tus cwj pwm los ntawm qhov tsis xws li Ra thiab Rz, thiab cov qauv qhia cov qauv ntsuas thiab ntsuas qhov ntev hauv qhov ntsuas qhov ntev kom tsis txhob muaj qhov yuam kev cuam tshuam rau qhov kev txiav txim.
Cov txheej txheem tswj cov txheej txheem yog sib npaug indispensable. Cov qauv muab kev pom zoo rau kev sib tsoo siab, kev sib hloov ceev (nrog rau kev sib hloov thiab kev hloov pauv ntawm cov phaj siab thiab qis), lub sijhawm ua haujlwm, thiab kev sib tsoo cov kua dej, thiab yuav tsum tau ua pov thawj raws li cov khoom siv thiab cov hom phiaj raug. Cov qauv tseem qhia meej meej txog qhov concentration, pH tus nqi, pom qhov tseeb, thiab hloov lub voj voog ntawm cov dej sib tsoo kom ua kom txias, lubrication, thiab nti tshem tawm cov teebmeem, thiab tiv thaiv kev sib kis thib ob thiab abrasive particle embedding. Qee qhov kev lag luam- cov qauv tshwj xeeb kuj tseem qhia txog cov kev xav tau ntawm kev ua haujlwm ib puag ncig (xws li kev hloov pauv kub, kev co txwv, thiab qib kev huv) kom txo tau qhov tsis zoo ntawm kev cuam tshuam sab nraud ntawm qhov raug.
Kev xeem thiab kev lees paub cov qauv yog ib feem tseem ceeb ntawm kev ua haujlwm. Cov qauv qhia meej txog cov kev cai metrological thiab calibration cycles rau cov khoom siv kuaj, qhia qhov feem pua thiab cov khoom rau thawj-txoj kev soj ntsuam, soj ntsuam xyuas, thiab tag nrho -cov khoom tiav, thiab pom zoo kom siv high- cov cuab yeej precision xws li kev sib koom tes ntsuas tshuab, flatness interferometers. They specify the format and time limits for recording, storing, and tracing testing data to facilitate traceability analysis in quality disputes or continuous improvement. Rau huab hwm coj- cov khoom tsim, cov qauv tseem tuaj yeem qhia txog kev tswj xyuas cov txheej txheem kev txheeb cais (SPC) los saib xyuas cov kev hloov pauv ntawm cov ntsiab lus tseem ceeb los ntawm kev tswj cov kab kos, ua tiav kev tiv thaiv zoo.
Nyob rau theem kev siv tus qauv, kev lag luam feem ntau siv cov txheej txheem hierarchical uas muaj cov qauv thoob ntiaj teb (xws li ISO series), cov qauv hauv tebchaws, thiab cov qauv kev lag luam / kev lag luam. Cov qauv thoob ntiaj teb muab ib hom lus rau kev lag luam thoob ntiaj teb thiab kev sib pauv thev naus laus zis, cov qauv hauv tebchaws tau ua kom zoo dua qub thiab ntxiv raws li cov yam ntxwv ntawm lawv cov kev lag luam kev lag luam, thiab kev lag luam thiab cov qauv kev lag luam ntxiv tob zuj zus cov khoom tshwj xeeb lossis cov txheej txheem, tsim cov txheej txheem dav dav los ntawm qhov tshwj xeeb. Thaum siv, nws yog ib qho tseem ceeb uas yuav tsum tau hais txog kev sib koom tes thiab kev hloov kho cov qauv, tam sim ntawd koom nrog kev ua tiav ntawm cov thev naus laus zis tshiab, cov khoom siv, thiab cov txheej txheem los tiv thaiv cov qauv qub los ntawm kev cuam tshuam kev txhim kho kom zoo.
Zuag qhia tag nrho, kev siv cov qauv rau ob npaug -sab sib tsoo machined qhov chaw ua tiav cov txheej txheem kev ua haujlwm suav nrog cov cuab yeej ua haujlwm, kev ua haujlwm zoo, kev tswj cov txheej txheem, thiab kev sim thiab kev lees paub. Kev nruj me ntsis rau thiab kev txhim kho txuas ntxiv ntawm cov qauv no tsis yog tsuas yog ua kom muaj kev sib tw siab thiab sib xws ntawm cov khoom tab sis kuj txhim kho kev ruaj ntseg thiab kev taug qab ntawm cov txheej txheem tsim khoom, muab kev txhawb nqa zoo rau kev sib tw zoo ntawm siab -kev tsim khoom.
