Dab tsi yog cov txheej txheem rau CNC precision qhov chaw machining? Nyob rau hauv tus txheej txheem tus qauv tsim, kev xaiv kom raug ntawm cov ntaub ntawv tso tawm muaj qhov cuam tshuam tseem ceeb ntawm kev ua kom ntseeg tau qhov kev xav tau ntawm cov khoom thiab kev tsim nyog ntawm cov txheej txheem ua tiav.
Positioning datum muab faib ua nplua datum thiab coarse datum: coarse datum siv lub unmachined nto ntawm qhov dawb paug raws li qhov positioning datum. Lub fine datum siv lub tshuab nto raws li qhov positioning datum.
I. Cov lus qhia rau kev xaiv cov ntaub ntawv zoo
1. Lub hauv paus txheej txheem sib tshooj: Cov ntaub ntawv tsim cov txheej txheem saum npoo yuav tsum raug xaiv kom raug raws li qhov ua tau los tiv thaiv qhov chaw tsis raug los ntawm cov ntaub ntawv misalignment.
2. Cov txheej txheem hauv paus ntsiab lus: Txhawm rau kom ntseeg tau qhov tseeb qhov tseeb ntawm qhov chaw ntawm lub tshuab, ntau qhov chaw ntawm lub workpiece yuav tsum tau machined siv tib cov ntaub ntawv zoo.
3. Workpiece processing deg benchmark cov lus qhia rau ib leeg: cov txheej txheem rov ua dua ntawm ob qhov chaw ua haujlwm tuaj yeem siv los ua kev sib koom ua ke.
4. Txij li cov txheej txheem ntsuas kev ntsuas: qee qhov txheej txheem txheej txheej saum npoo yuav tsum muaj kev ua haujlwm me me thiab tsis sib xws, feem ntau ua rau saum npoo nws tus kheej raws li qhov raug ntsuas.
Cov txheej txheem hais saum toj no rau kev xaiv qhov kev ntsuas zoo tshaj plaws yog qee zaum ua tsis tau raws li tib lub sijhawm, yuav tsum tau txiav txim siab raws li qhov xwm txheej tiag tiag.
Qhov thib ob, kev xaiv ntawm cov lus qhia ntxhib ntawm cov qauv ntsuas
1. Thawj zaug cov txheej txheem ua haujlwm yuav tsum siv cov coarse datum, coarse datum xaiv yog qhov tseeb, tsis yog tsuas yog cuam tshuam rau thawj txheej txheem ntawm kev ua, tab sis kuj muaj kev cuam tshuam zoo rau tag nrho cov txheej txheem ntawm lub workpiece.
2. Tus qauv tsim nyog ntawm kev sib faib machining kam rau ua: lub machining pub ntawm workpiece nto yuav tsum tau khaws cia tusyees, nrog rau qhov tseem ceeb nto raws li cov ntxhib datum.
3. Ib qho yooj yim clamping txheem: Yuav kom lub workpiece positioning ruaj khov thiab clamping ruaj ntseg, kwv yees siv taw tes xaiv yog yuav tsum tau kom du thiab huv si li sai tau, tsis muaj xob laim tawm tsam, thiab forging txiav los yog lwm yam shortcomings raug tso cai kom muaj ib tug zoo meej. txaus siab txhawb cheeb tsam.
