Qhia txog tus ntoo laum me ntsis

Khoom

Ntau cov ntaub ntawv sib txawv tau siv rau kev xyaum laum, nyob ntawm qhov yuav tsum tau ua.

Tungsten carbide: Tungsten carbide thiab lwm tus carbides yog qhov nyuaj heev thiab tuaj yeem tho zoo txhua cov ntaub ntawv, thaum tuav ib qho ntev dua li lwm cov khoom me me. Cov khoom kim heev thiab ntau ntau dua li nkig dua li cov hlau; Thiaj li lawv tsuas yog siv rau cov lus qhia tho-ntsis, cov khoom me me ntawm cov khoom tawv tawv tawv los yog brazed mus rau qhov taub ntawm me ntsis ua los ntawm cov hlau nyuaj.

Txawm li cas los xij, nws tau dhau los ua cov khw ua haujlwm kom siv cov khoom carbide tawv. Hauv cov me me me me nws yog qhov nyuaj kom haum carbide cov lus qhia; Hauv qee qhov kev lag luam, feem ntau cov cim npe tshaj tawm cov tuam txhab kev tsim khoom, xav tau ntau lub qhov nrog diameters tsawg dua 1 hli, khoom carbide me me yog siv.

PCD: Polycrystalline Pob Zeb Diamond (PCD) yog ntawm qhov nyuaj tshaj plaws ntawm txhua cov ntaub ntawv twj thiab yog li ntawd tsis muaj kev tiv thaiv tsis muaj zog hnav. Nws muaj txheej txheej ntawm daim pob zeb diamond ntawm pob zeb diamond, feem ntau txog 0.5 hli (0.020 hauv) tuab, sib koom ua ke raws li ib qho kev txhawb nqa tungsten-carbide.

Cov khoom lag luam uas siv cov khoom siv me me no los ntawm kev nkag mus rau cov lus qhia lossis ntawm Sintering PCD rau hauv lub pob txha caj qaum nyob rau hauv lub tungsten-carbide "nib". NIB tau tom qab yuav raug ntsia mus rau tus ncej carbide; Nws tuaj yeem yog hauv av los ua av rau cov geometies uas yuav cuam tshuam li cas thiaj tsis ua tiav qhov "ntu me".

PCD cov khoom lag luam yog feem ntau siv nyob rau hauv lub tsheb, aerospace, thiab lwm yam ntaub ntawv muaj fiber ntau, thiab siv cov khoom siv abbon monoxative, thiab lwm yam khoom siv hauv qab yog tsim nyog tus nqi tshwj xeeb. PCD tsis siv rau ntawm cov hlau ferrous vim qhov dhau los ntawm cov tshuaj tiv thaiv ntawm cov pa roj carbon hauv PCD thiab hlau nyob hauv cov hlau.

Hlau

Mos Tsawg-Carbon Steel Khoomyog pheej yig, tab sis tsis txhob tuav ib qho ntug zoo thiab yuav tsum tau ua ntau dua. Lawv tsuas yog siv rau cov ntoo drilling; Txawm ua haujlwm nrog hardwoods es tsis yog softwoods tuaj yeem pom tau lawv li kev ua phem.

Cov khoom lag luam ua los ntawmHigh-carbon steelmuaj ntau ruaj duaTsawg-cov roj carbon steelVim tias cov khoom muaj conferened los ntawm tawv tawv thiab tempering cov khoom siv. Yog tias lawv tau overheated (piv txwv li, los ntawm kev sib txhuam cua kub thaum ua haujlwm drilling) lawv poob lawv txoj kev npau taws, ua rau muaj qhov muag txiav. Cov khoom no tuaj yeem siv rau ntawm cov ntoo lossis hlau.

High-ceev steel (hss) yog ib daim ntawv ntawm cov cuab yeej hlau; HSS cov khoom me me yog qhov nyuaj thiab ntau dua kev tiv taus rau cov cua sov dua li cov pa roj carbon. Lawv tuaj yeem siv coj mus laum hlau, tawv ntoo, thiab lwm cov ntaub ntawv ntawm ntau dua cov txheej txheem ntau dua carbon-steel cov hlau, thiab muaj cov roj carbon hlau loj.

Cobalt steel alloysmuaj kev hloov pauv ntawm cov hlau ceev ceev uas muaj ntau dua cobalt. Lawv tuav lawv lub hardness ntawm ntau ntau dua qhov kub thiab yog siv los tho stainless hlau thiab lwm cov ntaub ntawv nyuaj. Lub ntsiab tseem ceeb ntawm kev cob tus hlau loj yog tias lawv muaj ntau nkev dua li cov qauv hss.

Daim plhaub

Black Oxide

Black oxide yog cov pheej yig dub txheej. Ib lub oxide oxide coating muab cov kub tiv hluav taws xob thiab cov yas, nrog rau corrosion tsis kam. Cov txheej nce lub neej ntawm cov hlau loj-hlau loj

Titanium nitride

Titanium nitride (tin) yog ib qho nyuaj heev metallic cov khoom uas tuaj yeem siv los ua kom muaj lub zog loj dua (feem ntau yog lub neej sib txawv los ntawm peb lossis ntau zaus. Txawm tias tom qab hliav, tus thawj coj ntawm txheej tseem muab kev txhim kho kom txiav thiab lub neej.

Cov yam ntxwv

taw tes kaum ntse ntse

Lub ntsiab lus kaum sab xis, lossis lub kaum sab xis tsim ntawm qhov taub ntawm me ntsis, yog txiav txim siab los ntawm cov khoom siv nyuaj, thiab cov khoom so softer yuav tsum muaj lub kaum ntse ntse. Qhov tseeb lub ntsiab lus rau lub hardness ntawm cov khoom cuam tshuam kev cuam tshuam wandering, chatter, lub qhov zoo, thiab coj tus nqi.

qho ntev

Lub luag haujlwm ntev ntawm kev txiav txim siab me ntsis li cas lub qhov tuaj yeem driffing, thiab kuj txiav txim siab txhav txhav ntawm me ntsis thiab qhov tseeb ntawm cov restime lub qhov. Thaum lub sij hawm ntev tuaj yeem tho qhov tob tob, lawv tau yoog tau ntau lub qhov lawv laum yuav muaj qhov chaw tsis raug lossis tab tom laij ntawm cov axis tsis raug. Twist drill bits are available in standard lengths, referred to as Stub-length or Screw-Machine-length (short), the extremely common Jobber-length (medium), and Taper-length or Long-Series (long).

Feem ntau lub laum cov khoom rau cov neeg siv khoom siv muaj cov shanks ncaj. Rau kev ua haujlwm hnyav drilling hauv kev lag luam, cov menyuam yaus nrog lub ntsej muag shanks yog qee zaum siv. Lwm Hom Shank siv suav nrog Hex-puab, thiab ntau cov tswv yim tawm ceev ceev.

Txoj kev hla-rau-ntev piv ntawm laum me ntsis feem ntau yog 1: 1 thiab 1:10. Ntau cov lus sib piv tau yog ua tau (piv txwv li, "dav hlau-ntev"), tab sis qhov ntau dua qhov kev sib tw ua haujlwm zoo.

Hom ntawm tho cov khoom:

Pom hniav yog tias tsis siv tam sim ntawd, nws yuav tsum tau tiaj tus lossis siv lub qhov los dai rau ntawm ko taw tiaj, thiab noo noo thiab kev tiv thaiv corrosion yuav tsum tau txiav txim siab.

Brad spin point (dowel laum me ntsis):

Lub Brad poink laum me ntsis (tseem hu ua di ncauj thiab dowel laum me ntsis) yog qhov sib txawv ntawm twist laum me ntsis uas yog qhov zoo rau kev drilling hauv ntoo.

Siv lub tsev tiaj tus laum me ntsis lossis ib tus kauv laum me ntsis, haum rau cov haujlwm uas bolts lossis txiv ntoo yuav tsum tau muab zais.

Brad ntsiab lus laum tawm yog ib txwm muaj nyob rau hauv diameters los ntawm 3-16 hli (0.12-0.63 hauv).

Los ntawm cov laum me ntsis

Ib lub qhov ntawm lub qhov yog qhov uas mus dhau tag nrho cov haujlwm ua haujlwm.

Siv tus kauv laum me ntsis rau kev nkag nrawm, haum rau kev ua haujlwm drilling.

Pob khawm Tog

Lub pob khawm xaws lub zog yog ib qho piv txwv ntawm kev cai laum qoj tsim qauv rau ib daim ntawv thov.
Tus kws tshaj lij pob khawm tshwj xeeb tau tsim kho uas siv cov phab ntsa ntawm 35 hli (1.4 hauv) boardle board, rau kev txhawb nqa.

FYSTner Bit

Cov khoom lag luam forstner, muaj npe tom qab lawv cov tswv cuab, ris ntsej muag meej, tiaj-hauv qab qhov ntawm cov ntoo, hauv ib qho kev taw qhia nrog kev hwm ntoo. Lawv tuaj yeem txiav ntawm ntug ntawm ib thaiv ntawm ntoo, thiab tuaj yeem txiav cov qhov; Rau cov ntawv thov zoo li lawv ib txwm siv hauv tho presses lossis lathes es tsis yog siv hluav taws xob siv hluav taws xob.
