Feem ntau, xyaum xyaum nrog lub cheeb ntawm ntau tshaj 1 hli yog hu ua me qhov xyaum xyaum, thiab xyaum xyaum nrog ib tug txoj kab uas hla ntawm tsawg tshaj li 1 hli yog hu ua micro-qhov xyaum. Kev ua haujlwm ntawm micro-qhov yog qhov nyuaj heev, uas yog qhov kev lees paub ua teeb meem hauv tsev thiab txawv teb chaws. Raws li cov txheej txheem ua tiav, cov txheej txheem ua haujlwm ntawm micro-qhov drilling tuaj yeem muab faib ua ob pawg: kev ua tshuab thiab kev ua haujlwm tshwj xeeb. Raws li kev txheeb cais, raws li cov txheej txheem yooj yim xws li cov micro-qhov sib txawv yuav tsum tau ua, precision, nto roughness, qhov loj thiab cov duab, muaj txog 50 hom. Ib txoj kev ntawm machining microholes, xws li tshuaj lom neeg, laser, twist laum, plasma beam thiab abrasive.
1. Kev txawj xaiv cuab yeej
(1) Cov duab geometric ntawm micro laum feem ntau yog ib qho kev xyaum ua haujlwm, uas tuaj yeem ua kom lub zog ntawm cov cuab yeej zoo, tiv thaiv qhov txiav ntawm viav vias, thiab pab txhawb kev tsim khoom thiab clamping.
(2) Qhov yuav tsum tau ua ntawm cov cuab yeej tuav thiab chuck yog siab, vim tias txhua qhov kev ua yuam kev radial yuav muaj kev cuam tshuam zoo rau lub laum micro.
(3) Cov khoom siv matrix ntawm micro-drill feem ntau yog cobalt-muaj hmoov high-speed steel thiab cemented carbide, thiab qee qhov muaj cov qauv sib xyaw, xws li ntxiv pob zeb diamond thiab cubic boron oxide rau pem hauv ntej ntawm lub laum, thiab txheej txheej. sab nraum lub cuab yeej nrog TiC thiab PCD txheej.
(4) Qhov dav dav drilling qhov tob ntawm micro-drills yog 10 mus rau 15 npaug ntawm txoj kab uas hla, thiab qhov yuam kev roundness ntawm lub aperture tuaj yeem tswj tau hauv 0.0025mm.
2. Yuav siv cov cuab yeej li cas
(1) Thaum lub sij hawm micro-qhov drilling, vim cov chips tsim me me los sis txawm hmoov, txiav cov cua sov nkag mus rau hauv cov chips tsis ntau, thiab cov roj pos huab thiab compressed cua tuaj yeem siv los pab tshem tawm cov nti thiab txias ntawm cov laum me ntsis. .
(2) Thaum lub micro-qhov laum yog drilling lub workpiece, tus nqi pub ntawm qhov pib ntawm kev txiav yog qis dua li qhov qub pub tus nqi ntawm kev txiav tom ntej rau hauv lub workpiece. Piv txwv li, thaum ua cov titanium alloys thiab high-temperature alloys, tus nqi pib pib yog 0.002mm. Tus nqi noj ib txwm yog 0.005mm.
(3) Thaum micro-drilling qhov chaw, nws yog qhov zoo tshaj plaws los txiav rau hauv workpiece ntawm lub kaum sab xis.
(4) Lub axis pub ntawm lub tshuab cuab yeej yuav tsum muaj qhov rhiab heev thiab kev daws teeb meem me me. Lub spindle muaj siab precision, zoo rigidity, zoo stability, thiab tsis tshua muaj kev co. Dynamic tshuav nyiaj li cas yuav tsum tau ua ua ntej ua.
5) Thaum drilling nrog micro-drills, txoj kev "pecking" drilling feem ntau yog siv.
6) Lub micro-drill yuav tsum raug xaiv kom haum rau cov khoom yuav tsum tau ua, geometry ntawm lub laum taub yuav tsum tau xaiv raws li cov khoom yuav tsum tau ua, thiab tsim nyog txiav tsis yuav tsum tau tsim nyob rau hauv thiaj li yuav muab tag nrho cov kev ua si mus rau qhov siab tshaj plaws. kev ua tau zoo ntawm micro laum.
