Dab tsi yog rab tswvyim laum me ntsis?
Jun 06, 2025| Twist laum cov khoom me yog cov khoom siv ntau tshaj plaws thiab ntau yam siv hauv kev siv drilling. Txawm hais tias nyob rau hauv kev ua haujlwm ua haujlwm, kev tsim ua pas dej, lossis kev tsim kho dav dav, cov khoom no yog qhov tseem ceeb rau kev tsim qhov hauv ntau yam khoom. Lawv tus qauv tsim, ua haujlwm, thiab muaj dav ua rau lawv ib qho staple nyob rau hauv cov kev cob qhia kev ua haujlwm thiab cov khoom lag luam DIY.
Anatomy ntawm Twist laum me ntsis
Lub twist laum me ntsis muaj ntau qhov tseem ceeb:
Taw tes (qhia): tus ntse kawg uas tau pib lub qhov. Nws feem ntau yog av rau 118-degree lossis 135-degree kaum sab xis, nyob ntawm cov khoom siv drilled.
Flutes: cov kauv grooves uas khiav raws qhov ntev ntawm me ntsis. Cov channel no pab tshem cov chips (txiav cov khoom siv) los ntawm lub sijhawm thaum tso cai coolant lossis roj nplua nyeem kom ncav cuag cov npoo txiav.
Lub cev: Qhov feem tseem ceeb ntawm cov nplaim taws, uas suav nrog cov nplaim taws thiab npoo (nqaim nqaim raws cov npoo uas coj qhia me ntsis hauv lub qhov).
Shank: Qhov tsis -} l} txiav xaus uas tau clamped rau hauv lub laum chuck. Shanks tuaj yeem ncaj ncees (rau feem ntau cov kav hlau feem ntau) lossis tapered (ib txwm muaj machinery machinery).
Yuav ua li cas jatist laum kev ua haujlwm
Thaum ib tug twist laum lub rotates, nws txiav cov npoo shear deb cov khoom, tsim ib lub qhov. Cov nplaim dej khiav tawm lub khib nyiab, tiv thaiv kev txhaws thiab kub siab. Lub kaum sab xis ntawm lub ntsiab lus cuam tshuam rau kev txiav tawm me ntsis {{degree) yog qhov zoo dua rau cov softer zoo li ntoo (135 degree) yog qhov zoo dua rau cov hlau nyuaj.
Hom Twist Laum Khoom
Ntswj laum cov khoom lag luam tuaj hauv kev sib txawv kom haum cov kev xav tau tshwj xeeb:
High - Ceev Hlau (HSS): Feem ntau hom, haum rau drilling ntoo, yas, thiab softer me me.
Cobalt alloy: muaj cobalt rau cov tshav kub nce ntxiv, ua rau nws zoo tagnrho rau kev drilling stainless hlau thiab lwm yam nyhav me me.
Carbide - tipped: nta tus carbide txiav ntug rau huab durability, feem ntau siv nyob rau hauv masonry thiab cov khoom muaj abrasive.
Titanium {-} coated: coated nrog titanium nitride (tin) kom txo qis kev sib txhuam thiab txuas ntxiv lub neej.
Cov Kev Siv Cov Ntawv Siv
Twist laum cov khoom me yog siv thoob plaws ntau kev lag luam:
Hlau ua haujlwm: Drilling ncaj qhov hauv cov hlau, txhuas, thiab lwm yam hlau.
Woodworking: Tsim cov qhov huv si hauv moswood, hardwood, thiab plywood.
Cov ntaub ntawv yas & Composites: Tiv thaiv kev tawg lossis yaj nrog cov khoom ntse, cov av kom zoo.
Kev Kho Vaj Tse & kev tsim kho: Muaj txiaj ntsig rau kev txhim kho vaj tse hauv tsev, los ntawm dai txee rau kev sib sau tog.
Xaiv txoj cai twist laum me ntsis
Xaiv qhov tseeb yog nyob ntawm:
Cov khoom siv: phim me ntsis hom (hss, cobalt, thiab lwm yam) rau lub workpiece.
Qhov loj me: Cov qauv ntau thiab tsawg ntawm cov micro - tho (qis dua 25 hli).
Kev nrawm & Pub tus nqi: Cov ntaub ntawv Harder xav tau qeeb qeeb nrawm kom tsis txhob muaj kev kub siab.
Txij Nkawm & Hliav
Kom ntev ntswj laum me ntsis lub neej:
Siv cov kua dej thaum drilling hlau los txo cov cua sov.
Cov khw muag khoom loj kom tiv thaiv kev puas tsuaj rau cov txiav cov npoo.
Cov khoom npub npub uas siv lub rooj sib tsoo lossis tshwj xeeb cov cuab yeej ntse.
