Qhia txog Wood Drill Bit

Khoom siv

Ntau cov ntaub ntawv sib txawv yog siv rau lossis rau cov khoom siv tho, nyob ntawm seb yuav tsum tau thov.

Tungsten Carbide： Tungsten carbide thiab lwm yam carbides yog qhov nyuaj heev thiab tuaj yeem xyaum siv txhua yam ntaub ntawv, thaum tuav lub ntug ntev dua lwm cov khoom.Cov khoom siv yog kim thiab nkig ntau dua li cov hlau;yog li ntawd lawv tsuas yog siv rau kev xyaum-ntsis cov lus qhia, me me ntawm cov khoom siv tawv ruaj ruaj los yog brazed mus rau qhov kawg ntawm me ntsis ua los ntawm cov hlau tsis tshua muaj zog.

Txawm li cas los xij, nws tau dhau los ua ntau hauv cov khw muag khoom siv cov khoom carbide khoom.Hauv qhov me me heev nws yog qhov nyuaj kom haum cov lus qhia carbide;Hauv qee qhov kev lag luam, tshwj xeeb tshaj yog cov ntawv luam tawm Circuit Board tsim, xav tau ntau qhov nrog cov kab uas hla tsawg dua 1 hli, cov khoom siv carbide khoom siv.

PCD： Polycrystalline pob zeb diamond (PCD) yog ib qho nyuaj tshaj plaws ntawm tag nrho cov cuab yeej siv thiab yog li ntawd tsis tshua muaj siab hnav.Nws muaj ib txheej ntawm pob zeb diamond hais, feem ntau txog 0.5 hli (0.020 nyob rau hauv) tuab, sib koom ua ib pawg sintered rau kev txhawb nqa tungsten-carbide.

Cov khoom siv yog tsim los ntawm kev siv cov khoom siv no los ntawm kev sib tsoo me me mus rau qhov kawg ntawm lub cuab yeej los ua cov npoo txiav los yog los ntawm sintering PCD rau hauv cov hlab ntsha hauv tungsten-carbide "nib".Lub nib tuaj yeem tom qab tau brazed rau carbide ncej;Nws tuaj yeem ua rau hauv av rau cov geometry nyuaj uas yuav ua rau tsis ua haujlwm braze hauv cov "segment" me me.

PCD cov khoom siv feem ntau yog siv rau hauv tsheb, aerospace, thiab lwm yam kev lag luam los laum abrasive aluminium alloys, carbon-fiber reinforced plastics, thiab lwm yam ntaub ntawv abrasive, thiab nyob rau hauv daim ntawv thov uas lub tshuab downtime los hloov los yog sharpen hnav cov khoom yog tshwj xeeb tshaj yog kim.PCD tsis siv rau cov hlau ferrous vim kev hnav ntau dhau los ntawm cov tshuaj tiv thaiv ntawm cov pa roj carbon hauv PCD thiab cov hlau hauv cov hlau.

Hlau

Mos low-carbon steel khoomyog pheej yig, tab sis tsis tuav ib tug ntug zoo thiab yuav tsum tau nquag sharpening.Lawv tsuas yog siv rau drilling ntoo;Txawm tias ua hauj lwm nrog hardwoods es tsis softwoods tuaj yeem pom lawv lub neej luv.

Cov khoom ua los ntawmhigh-carbon hlauyog ruaj dualow-carbon steel khoomvim cov khoom sib tham los ntawm hardening thiab tempering cov khoom.Yog hais tias lawv overheated (xws li, los ntawm kev sib txhuam cua sov thaum drilling) lawv poob lawv temper, uas ua rau ib tug mos txiav ntug.Cov khoom no tuaj yeem siv rau ntawm ntoo lossis hlau.

High-speed steel (HSS) yog ib daim ntawv ntawm cov cuab yeej steel;HSS cov khoom yog qhov nyuaj thiab tiv taus cua sov ntau dua li cov pa roj carbon siab.Lawv tuaj yeem siv los laum hlau, ntoo tawv, thiab lwm yam khoom siv feem ntau ntawm kev txiav nrawm dua li cov khoom siv hlau, thiab tau hloov cov pa roj carbon ntau.

Cobalt hlau alloysyog variations ntawm high-speed steel uas muaj ntau cobalt.Lawv tuav lawv cov hardness ntawm qhov kub thiab txias ntau dua thiab siv los laum stainless hlau thiab lwm yam ntaub ntawv nyuaj.Lub ntsiab tsis zoo ntawm cobalt steels yog tias lawv nkig ntau dua li cov qauv HSS.

Txheej

Dub oxide

Dub oxide yog ib qho pheej yig dub txheej.Lub oxide dub txheej muab cov cua sov ua haujlwm thiab lubricity, nrog rau kev tiv thaiv corrosion.Cov txheej ua kom lub neej ntawm high-speed steel khoom

Titanium nitride

Titanium nitride (TiN) yog cov khoom siv hlau hnyav heev uas tuaj yeem siv los npog lub siab ceev steel me ntsis (feem ntau yog twist me ntsis), txuas lub neej txiav los ntawm peb lossis ntau dua.Txawm tias tom qab sharpening, cov ntug ntawm txheej tseem muab kev txhim kho kev txiav thiab lub neej ntev.

Yam ntxwv

taw tes kaum

Lub kaum sab xis, los yog lub kaum sab xis tsim ntawm lub ntsis, yog txiav txim los ntawm cov khoom uas lub ntsis yuav ua hauj lwm.Qhov tseeb taw tes lub kaum sab xis rau qhov hardness ntawm cov khoom cuam tshuam rau wandering, chatter, qhov zoo, thiab hnav tus nqi.

ntev

Qhov kev ua haujlwm ntev ntawm me ntsis txiav txim siab seb qhov tob npaum li cas tuaj yeem drilled, thiab tseem txiav txim siab qhov nruj ntawm qhov me ntsis thiab qhov tseeb ntawm qhov tshwm sim.Thaum cov khoom siv ntev ntev tuaj yeem xyaum qhov tob dua, lawv hloov tau ntau lub ntsiab lus tias lub qhov lawv xyaum yuav muaj qhov tsis raug lossis txav mus los ntawm qhov xav tau.Twist laum cov khoom muaj nyob rau hauv cov qauv ntev, hu ua Stub-ntev lossis Screw-Machine-ntev (luv), feem ntau Cov Haujlwm-ntev (nruab nrab), thiab Taper-ntev lossis Ntev-Series (ntev).

Feem ntau cov laum me me rau cov neeg siv khoom siv tau ncaj shanks.Rau lub luag haujlwm hnyav drilling hauv kev lag luam, cov khoom siv nrog tapered shanks qee zaum siv.Lwm hom shank siv suav nrog hex-puab, thiab ntau yam kev tso tawm sai sai.

Qhov sib piv ntawm txoj kab uas hla-rau-ntev ntawm qhov xyaum yog feem ntau ntawm 1: 1 thiab 1: 10.Qhov sib piv ntau dua tuaj yeem ua tau (piv txwv li, "aircraft-ntev" twist bits, pressured-roj rab phom xyaum, thiab lwm yam), tab sis qhov sib piv ntau dua, qhov kev sib tw ntau dua ntawm kev ua haujlwm zoo.

Hom Drill Bits:

Pom hniav Yog tsis siv tam sim ntawd, nws yuav tsum tiaj tus los yog siv lub qhov rau dai, los yog lwm yam khoom tsis tuaj yeem muab tso rau ntawm lub tiaj tus taw pom cov hniav, thiab cov dej noo thiab kev tiv thaiv corrosion yuav tsum tau txiav txim siab.

Brad point ntsis (Dowel Drill Bit):

Lub brad point laum ntsis (tseem hu ua di ncauj thiab spur laum me ntsis, thiab dowel laum me ntsis) yog ib qho kev hloov ntawm twist laum me ntsis uas yog optimized rau drilling hauv ntoo.

Siv lub tiaj tus ntoo laum me ntsis los yog ib lub tshuab spiral laum me ntsis, haum rau cov hauj lwm qhov twg bolts los yog txiv ntseej yuav tsum tau muab zais.

Brad taw tes laum khoom feem ntau muaj nyob rau hauv txoj kab uas hla ntawm 3-16 hli (0.12-0.63 nyob rau hauv).

Los ntawm qhov Drill Bit

Ib lub qhov los ntawm lub qhov yog ib lub qhov uas mus los ntawm tag nrho cov workpiece.

Siv lub tshuab laum me me rau kev nkag mus sai, haum rau kev ua haujlwm dav dav.

Pob khawm sinker me ntsis

Lub pob khawm sinker ntsis yog ib qho piv txwv ntawm kev cai xyaum me ntsis tsim rau ib daim ntawv thov tshwj xeeb.
Cov pob khawm tshwj xeeb tau tsim los siv cov phab ntsa ntawm lub qhov taub 35 hli (1.4 nyob rau hauv) txoj kab uas hla, dhuav nyob rau hauv particle board, rau kev txhawb nqa.

Forstner ntsis

Forstner cov khoom, muaj npe tom qab lawv tus neeg tsim khoom, tho qhov tseeb, lub qhov hauv qab ntawm cov ntoo, hauv txhua qhov kev taw qhia txog kev hwm ntoo.Lawv tuaj yeem txiav ntawm ntug ntawm ib qho thaiv ntoo, thiab tuaj yeem txiav qhov sib tshooj;rau cov ntawv thov no feem ntau yog siv rau hauv cov xovxwm lathes lossis lathes es tsis yog hauv tes tuav hluav taws xob xyaum.

Cov Lus Qhia me me rau Kev Siv Ntoo Drill Bits
