Thaum peb cuam tshuam nrog kev ua haujlwm txhua hnub, peb feem ntau hais txog cnc machining v850 qhov tseeb, tab sis koj puas yog qhov tseeb? Los yog nws nruj? Cia's mus saib ua ke!
Machining raug yog qhov kev sib haum xeeb ntawm qhov loj me, cov duab, thiab txoj hauj lwm ntawm qhov chaw ntawm qhov kev ua tiav nrog rau qhov zoo tshaj plaws geometric tsis xav tau los ntawm daim duab! Qhov zoo tshaj plaws geometric tsis yog qhov nruab nrab ntawm qhov loj me; nyob rau hauv cov nqe lus ntawm cov duab, lawv yog kiag li lub voj voog, lub tog raj kheej, dav hlau, cones, thiab cov kab ncaj; rau kev sib nrig sib txoj hauj lwm, lawv yog kiag li parallel, perpendicular, coaxial, thiab lwm yam. Symmetry thiab hais txog.
1. Dimensional raug
Lub degree ntawm conformity ntawm qhov loj me me ntawm qhov ua tiav thiab qhov nruab nrab ntawm qhov kam rau ua ib feem ntawm qhov loj.
2. Cov duab raug
Hais txog qhov kev sib haum xeeb ntawm qhov tseeb geometric duab ntawm qhov chaw ntawm qhov ua tiav thiab qhov zoo tshaj plaws geometric duab.
3. Qhov tseeb ntawm qhov chaw
Hais txog qhov tseeb qhov tseeb qhov sib txawv ntawm qhov chaw ntawm cov khoom tom qab ua tiav.
4. Kev sib raug zoo
Feem ntau, thaum tsim cov khoom siv tshuab thiab qhia txog qhov tseeb ntawm cov khoom, yuav tsum tau them nyiaj rau kev tswj xyuas qhov kev ua yuam kev nyob rau hauv txoj hauj lwm kam rau ua, thiab txoj hauj lwm yuam kev yuav tsum tsawg tshaj li qhov kam rau ua. Ntawd yog, qhov tseeb ntawm qhov chaw lossis qhov chaw tseem ceeb ntawm qhov chaw, qhov kev xav tau ntawm qhov raug yuav tsum siab dua li qhov yuav tsum tau ua ntawm txoj haujlwm raug, thiab qhov yuav tsum tau muaj qhov tseeb ntawm txoj haujlwm yuav tsum siab dua qhov yuav tsum tau muaj qhov tseeb.
Qhov sib txawv ntawm qhov tseeb geometric tsis ntawm ib feem los ntawm qhov zoo tagnrho geometric tsis yog hu ua machining yuam kev. Qhov loj ntawm machining yuam kev qhia txog qib ntawm machining raug. Qhov yuam kev ntau dua, qhov qis dua qhov tseeb ntawm machining, thiab qhov me me qhov yuam kev, qhov siab dua qhov machining raug.
1. Kev taw qhia luv luv ntawm machining raug
Machining raug yog tsuas yog siv rau qib ntawm cov khoom tsim. Machining raug thiab machining yuam kev yog ob nqe lus siv los soj ntsuam cov geometric tsis ntawm lub tshuab machined nto. Machining raug yog ntsuas los ntawm qib kam rau ua, qhov tsawg dua tus nqi qib, qhov raug siab dua; kev ua yuam kev yog qhia los ntawm tus lej tus nqi, qhov loj dua tus lej, qhov ntau dua qhov yuam kev. High machining raug txhais tau tias me me machining yuam kev, thiab vice versa.
Muaj 20 qib kam rau ntawm IT01, IT0, IT1, IT2, IT3 rau IT18. Yog hais tias IT01 qhia tias ib feem muaj qhov siab tshaj plaws machining raug, IT18 qhia tias ib feem muaj qhov qis tshaj machining raug. Feem ntau, IT7 thiab IT8 muaj qhov nruab nrab machining raug. qib.

Qhov tseeb tsis tau los ntawm txhua txoj kev machining yuav tsis raug kiag li. Los ntawm qhov kev xav ntawm kev ua haujlwm ntawm ib feem, tsuav yog qhov ua yuam kev machining nyob rau hauv qhov kev zam ntau yam uas yuav tsum tau ua los ntawm qhov kev kos duab, nws tau txiav txim siab tias qhov tseeb machining yog lav.
Qhov txawv ntawm qhov tseeb thiab qhov tseeb:
1. Qhov tseeb
Hais txog qhov sib ze ntawm qhov tau txais qhov ntsuas tau thiab tus nqi tseeb. Kev ntsuas qhov raug siab txhais tau hais tias qhov kev ua yuam kev yog me me. Lub sijhawm no, qhov nruab nrab tus nqi ntawm cov ntaub ntawv ntsuas deviates tsawg dua los ntawm tus nqi tseeb, tab sis cov ntaub ntawv tau tawg, uas yog, qhov loj ntawm qhov yuam kev yuam kev tsis meej.
2. Precision
Hais txog kev rov tsim dua tshiab thiab sib xws ntawm cov txiaj ntsig ntawm kev ntsuas rov qab siv tib yam ntawm cov qauv seem. Nws yog tau hais tias qhov precision yog siab, tab sis qhov precision tsis yog. Piv txwv li, peb qhov txiaj ntsig tau los ntawm kev ntsuas qhov ntev ntawm 1 hli yog 1.051 hli, 1.053, thiab 1.052, raws li. Txawm hais tias lawv cov precision siab, lawv tsis raug.
Qhov tseeb sawv cev rau qhov tseeb ntawm cov txiaj ntsig ntsuas, qhov tseeb sawv cev rau qhov rov ua dua thiab rov ua dua ntawm qhov ntsuas tau, thiab qhov tseeb yog qhov yuav tsum tau ua ua ntej rau qhov raug.
2. Cov txheej txheem los txhim kho machining raug
01
Kho cov txheej txheem txheej txheem
1) Kev sim txiav txoj kev hloov kho
Los ntawm kev sim txiav- ntsuas qhov loj-kho tus nqi ntawm cov cuab yeej txiav-txiav-sim txiav dua, thiab lwm yam kom txog thaum nws ncav cuag qhov loj me. Txoj kev no muaj kev ua haujlwm tsawg thiab feem ntau yog siv rau ib qho thiab cov khoom me me.
2) Txoj kev hloov kho
Qhov yuav tsum tau muaj yog tau los ntawm kev kho cov txheeb ze ntawm lub tshuab cuab yeej, fixture, workpiece thiab cuab tam ua ntej. Txoj kev no muaj cov khoom tsim tau siab thiab feem ntau yog siv rau kev tsim khoom loj.

Txo lub tshuab yuam kev
1) Txhim kho qhov raug ntawm cov khoom siv spindle
Kev sib hloov qhov tseeb ntawm cov kabmob yuav tsum tau txhim kho:
①Xaiv cov kabmob siab-precision dov bearings;
②Siv high-precision multi-roj wedge dynamic siab bearings;
③Siv high-precision hydrostatic bearings,
Yuav tsum txhim kho qhov tseeb ntawm cov khoom siv nrog cov kabmob:
① Txhim kho qhov tseeb machining ntawm lub thawv txhawb nqa qhov thiab cov ntawv xov xwm ntxaiv;
② Txhim kho qhov tseeb machining ntawm qhov chaw mating nrog cov kabmob;
③ Ntsuas thiab kho qhov radial runout ntau yam ntawm cov khoom sib thooj kom them lossis offset qhov yuam kev.
2) Preload lub dov bearing kom raug
① Qhov sib txawv tuaj yeem raug tshem tawm;
② Ua kom lub rigidity ntawm cov kabmob;
③ Kev sib npaug ntawm dov lub ntsiab lus yuam kev.
Txo qhov kev sib kis yuam kev ntawm cov saw hlau sib kis
1) Tus naj npawb ntawm cov kis tau tus mob me me, cov saw hlau kis tau luv luv, thiab qhov tseeb kis tau tus mob siab;
2) Kev siv kev txo qis kev sib kis yog ib txoj hauv kev tseem ceeb los xyuas kom meej qhov kev sib kis tau zoo, thiab qhov sib txuas sib txuas mus rau qhov kawg, qhov sib piv me me yuav tsum yog;
3) Qhov tseeb ntawm qhov kawg yuav tsum siab dua li ntawm lwm qhov sib kis.
Txo cov cuab yeej hnav
Ua ntej lub cuab tam loj hnav mus txog rau theem ntse hnav, lub cuab yeej yuav tsum tau rov ua dua.
