[Q] Kev siv thiab kev faib tawm ntawm kev sib tw ncaj nraim?
[A] Kev xyaum twist dub yog qhov ntse. Nws yog siv los laum ntoo thiab hlau, uas yog, qhov cuam tshuam nyiaj laum me ntsis ntawm kev xyaum ua haujlwm yog dull, uas yog siv los laum qhov hauv cov cement thiab cib ntsa, uas yog, kev tsim kho drilling. Thaum drilling, lub laum hluav taws xob yuav tsum tau kho kom haum rau qhov cuam tshuam.
[Q] Dab tsi yog qhov sib txawv ntawm qhov sib tsoo ntawm qhov sib tsoo thiab qhov sib tw?
[Q] Cov hlau laum me ntsis yog hais txog cov khoom me me uas ua los ntawm cov cemented carbide (xws li cov hlau alloy uas muaj tungsten), uas qhia txog cov khoom ntawm lub laum me ntsis; qhov twisted laum me ntsis qhia tau hais tias cov duab ntawm lub laum me ntsis yog twisted zoo li twisted, thiab nws xav qhia cov duab ntawm lub laum ntsis. Los ntawm txoj kev, feem ntau siv laum khoom yog twist xyaum, tab sis lawv tsis tas alloy.
[Q] Vim li cas ntswj kom txiav thaum drilling qhov?
[A] Lub kaum sab xis ntawm ntug ntawm lub laum me ntsis tsis phim cov khoom ntawm lub workpiece. Qhov teeb meem ntawm twist drilling tsis tuaj yeem daws tau (lub kaum sab xis ntawm ntug ntawm qhov sib tw twist tsis tuaj yeem hloov kho). Thaum drilling, cov laum chips tas li cuam tshuam nrog qhov xwm txheej ntawm cov khoom drilled. Feem ntau, cov ntaub ntawv softer thiab nplaum yuav tsis tawg cov chips los ntawm lawv tus kheej thaum drilling qhov, thiab lub laum me ntsis yuav tsum tau nqa ntau zaus thaum drilling. Tuaj tawm los ntxuav cov laum crumbs kom tiv thaiv lub laum me ntsis kom tsis txhob raug overwounded thiab cuam tshuam rau cov khib nyiab tshem tawm.
[Q] Lub ces kaum twg yog lub kaum sab xis ntawm lub pob zeb diamond twist?
[Cov lus teb] Lub kaum sab xis pem hauv ntej (piv txwv li lub kaum sab saum toj) ntawm tus qauv twist xyaum yog 120 degree ± 2 degree . Qhov hla-ntug bevel ntawm tus qauv twist xyaum yog li 50 degree ~ 55 degree. Lub kaum sab xis pem hauv ntej ntawm tus ntoo khaub lig yog -50 degree ~ -60 degree . Lub kaum sab xis ntawm tus qauv twist xyaum yog hais txog 30 degree ntawm lub ntsis ntawm 18 degree ~ 38 degree, thiab txog -30 degree nyob ze ntawm tus ntoo khaub lig-ntug. Lub kaum sab nraub qaum ntawm lub voj voog sab nraud ntawm qhov sib tw yog feem ntau 8 degree ~ 10 degree, thiab lub nraub qaum ntawm tus ntoo khaub lig yog 20 degree ~ 25 degree.
[Q] Cov cuab yeej siv tshuab dab tsi yog ua tiav rau lub taub hau ntawm qhov sib tw?
[Cov lus teb] Lub taub hau ntawm qhov sib tw yog ua tiav los ntawm lub tshuab milling. Mahua laum yog ib qho cuab yeej rau machining qhov los ntawm cov khoom siv, thiab nws kuj yog cov cuab yeej siv dav tshaj plaws hauv cov cuab yeej siv lub qhov. Lub twist laum yog ib qho cuab yeej rau drilling qhov puag ncig ntawm lub workpiece los ntawm kev txiav cov rotary ntawm nws cov txheeb ze ruaj axis. Nws yog lub npe vim hais tias cov nti zawj yog kauv thiab zoo li tus twist. Spiral slots muaj 2 qhov, 3 qhov los yog ntau dua, tab sis 2 qhov ntau tshaj plaws. Hemp drills tuaj yeem clamped ntawm phau ntawv thiab hluav taws xob txhais tes, twist drilling cov cuab yeej lossis cov tshuab drilling, milling tshuab, tshuab dhos thiab txawm tias cov chaw ua haujlwm. Cov khoom siv tho me ntsis feem ntau yog cov cuab yeej siab ceev hlau lossis cemented carbide.
