Vim hais tias lub qhov tob tob yog nqa tawm nyob rau hauv kev kaw lossis ib nrab kaw, nws tsis tuaj yeem pom ncaj qha qhov drilling ntawm CNC inserts. Yog li ntawd, qhov ua tau zoo thiab tsim nyog ntawm cov cuab yeej CNC yog qhov tseem ceeb heev rau kev ua haujlwm tsis zoo ntawm qhov drilling. Feem ntau, txoj cai tsim qauv ntawm kev siv lub qhov tob tob yuav tsum muaj peb tus qauv hauv qab no:
1. Cov qauv rau kev teev tseg thiab cov qauv ntawm cov hniav txiav
Lub hauv paus ntawm cutter hniav specifications thiab qauv yog los txais yuav cov kev mob ntawm txoj kev thauj khoom thauj los ntawm txhua cov hniav cutter nyob rau hauv tag nrho cov txheej txheem ntawm qhov drilling. Lub nruas load muaj feem xyuam rau tag nrho cov dav ntawm cov hniav txiav. Tag nrho cov dav ntawm cov hniav cutter yuav tsum tau muab faib raws li kev mob ntawm txhua tus hniav cutter thiab txoj kab uas hla ntawm me ntsis. Peb tus qauv yuav tsum raug xam rau kev xa tawm ntawm tag nrho cov dav ntawm cov hniav txiav:
A. lav lub eccentricity e=(0.1-0.2) d0 ntawm kev tho qhov taw tes. Tus nqi e yog cuam tshuam nrog cov khoom siv tau ua tiav thiab txoj kab uas hla ntawm lub laum ntsis. Nws loj los txiav txim seb qhov loj thiab cov kev taw qhia ntawm radial resultant quab yuam ntawm lub laum ntsis. Kev tsim nyog eccentricity ua rau qhov tsim nyog radial quab yuam xovxwm rau machined lub phab ntsa, uas ua si lub luag haujlwm ntawm lub twj ywm ruaj khov, txhim kho kev taw qhia thiab txhim kho qhov zoo ntawm lub qhov. Nyob rau tib lub sijhawm, xoom kev txiav ntawm laum taw tes zam, thiab qhov kev txiav tsis zoo ntawm qhov tseem ceeb yog kho tau.
B, A {{0}} C {{1}} e {{2}} F> d0 / 2 + (1 ~ 2) hli, uas yog, yuav tsum muaj qee qhov nqi ntawm kev sib tshooj ntawm cov hniav txiav;
C, A + CeF> (1-3) hli, uas tuaj yeem ua rau cov txiav radial quab yuam ib txwm nias ntawm phau ntawv qhia block, phau ntawv qhia thaiv thawb mus tom ntej ze rau ntawm cov phab ntsa ntawm lub qhov machined, ua tag nrho kev siv lub luag haujlwm ntawm cov lus qhia thaiv kom paub tseeb tias qhov drilling ncaj. Cov.
2. Cov Txheej Txheem rau Cov Khoom Raw ntawm Cutter Hniav
Cov ntaub ntawv nyoos ntawm cov hniav cutter yuav tsum tau xaiv raws li cov thauj khoom ntawm txhua tus hniav thiab kev mob. Lub hauv paus hniav yog raug rau cov quab yuam loj axial, loj dhau los ntawm kev sib txhuam thiab txhuam cov qauv tsis zoo. Yog li no, YG lossis YW cemented carbide cutter nrog lub siab flexural zog thiab kev cuam tshuam tiv thaiv yuav tsum tau txiav txim siab, thaum YT hom aluminium alloy nrog cov txiav ceev nrawm, zoo daim ntawv thov hardness thiab siab hnav kuj yuav tsum tau saws rau sab nrauv thiab nruab nrab cov hniav, thiab phau ntawv qhia thaiv yuav tsum ua kom ruaj khov. YT raw cov ntaub ntawv nrog kev sib tsoo siab. Rau kev ua cov hlau alloy, txhua qhov kev txiav cov hniav cov ntaub ntawv yuav tsum xaiv cov khoom siv zoo ntawm cov khoom siv raw, thiab YT798 yuav tsum tau xaiv nyob rau theem no.
3. Tus qauv rau Angle of NC Hniav
Lub kaum sab xis ntawm CNC twj rau qhov tob machining yog nyob ntawm cov khoom siv raw. Tsim nyog NC hniav tawg lub kaum sab xis yog qhov pab tau zoo heev kom ntseeg tau ruaj khov ntawm tag nrho cov txheej txheem ntawm laum rab koob, nti tawg thiab txhim kho cov cuab tam kom ruaj khov. Sab pem hauv ntej thiab nram qab lub kaum ntawm NC blades yog cov qhov tseem ceeb tshaj plaws lub ces kaum. Feem ntau ntawm cov ces kaum pem hauv ntej ntawm txhua qhov ntug drilling yog 0=00, cov txheej txheem nyuaj ntawm cov khoom nyoos yog 0=1 ~ 30, cov khoom siv nrog cov thev naus laus zis zoo yog 0=3 ~ 60, cov khoom siv thawb thiab txias-tawv tuaj yeem tuaj yeem tsis zoo; lub kaum sab xis ntawm lub kaum npoo sab nraud feem ntau yog 8 ~ 120, thiab lub kaum sab hauv yuav tsum loj dua, noj alpha 0=12 ~ 150.
