1. Cov khoom siv dav siv rau kev txiav cov khoom txiav
Kev kub ceev steel thiab cemented carbide feem ntau yog siv los ua cov ntaub ntawv txiav. Tsis tas li ntawd, cov ntaub ntawv superhard ceramic, cubic boron nitride thiab pob zeb diamond kuj tseem siv. Nyob rau hauv xyoo tas los no, cov cuab yeej txheej tshuab tau siv dav thiab ua tiav cov txiaj ntsig zoo.
(1) Kev kub ceev steel: kev kub ceev steel yog cov cuab yeej txiav cov khoom siv ntau yam xws li tungsten, chromium, molybdenum thiab vanadium ntxiv rau cov hlau alloy. W18Cr4V yog dav siv. Cov hlau no muaj cov khoom zoo thiab tuaj yeem tsim ntau yam cuab yeej txiav. Nws yog dav siv nyob rau hauv Suav teb. W6Mo5Cr4V2 yog cov hlau kub ceev nrog molybdenum ntxiv thiab tungsten txo. Nws lub zog dabtsi yog khoov thiab cuam tshuam lub zog yog siab dua W18Cr4V, thiab muaj cov khoom siv thermoplastic zoo thiab sib tsoo, uas yog tsim los ua cov cuab yeej tiv thaiv kev cuam tshuam.Tsis tas li ntawd, qee cov khoom siv high-speed steel tau tsim rau qee qhov tshwj xeeb uas yuav tsum tau ua.
(2) Cemented carbide: cemented carbide yog cov khoom siv ua haujlwm siab sintered los ntawm hmoov metallurgy nrog hlau carbides thiab hlau binders nrog siab hardness thiab melting point. Cov khoom siv cemented carbide feem ntau suav nrog tungsten cobalt, tungsten cobalt titanium thiab cov cemented carbide, sib xws rau K, P thiab M cemented carbide ntawm ISO tus qauv. TG hom cemented carbide yog tsim rau kev ua cov hlau cam khwb cia thiab cov ntaub ntawv tsis-ferrous hlau, YT hom cemented carbide yog tsim rau kev ua cov pa roj carbon steel los yog hlau alloy steel cov ntaub ntawv, thaum YW hom cemented carbide tuaj yeem ua cov hlau cam khwb cia, cov hlau tsis muaj hlau thiab cov ntaub ntawv hlau.
(3) Superhard cov ntaub ntawv: nrog rau kev txhim kho ntawm kev siv tshuab, ntau yam khoom siv superhard tau tsim, xws li ceramics, cubic boron nitride (CBN), polycrystalline cubic boron nitride (PCBN) thiab pob zeb diamond. Cov ntaub ntawv txiav cov cuab yeej no feem ntau yog siv rau lub sijhawm tshwj xeeb, xws li kev kub ceev txiav, txiav qhuav, txiav cov khoom siv tshuab nyuaj, tig es tsis txhob sib tsoo, thiab lwm yam. Tus nqi ntawm cov ntaub ntawv no feem ntau yog siab, thiab cov kev txiav thiab cov txheej txheem. tsis yooj yim rau tus tswv. Muaj qee qhov yuav tsum tau ua rau lub rigidity thiab txiav ceev ntawm cov cuab yeej siv tshuab thiab txawm tias cov cuab yeej sib tsoo, uas tsis yog siv dav hauv kev ua cov pa.
(4) Cov cuab yeej txheej: cov cuab yeej nto txheej yog ib txoj hauv kev tseem ceeb los txhim kho cov cuab yeej ua haujlwm, uas tau siv dav hauv xyoo tas los no.
Cov khoom siv feem ntau yog titanium carbide tic, titanium nitride tin thiab aluminium oxide Al2O3. Ib txheej txheej hniav yog tsis tshua muaj siv. Feem ntau, cov thev naus laus zis ntawm TiC tin ob txheej txheej txheej txheej lossis tic-al2o3- tin peb-txheej txheej txheej tau txais yuav. Lub neej kev pab cuam ntawm cemented carbide hniav tuaj yeem nce ntau zaus tom qab txheej txheej txheej. Cov txheej txheem txheej tsis yog tsuas yog siv rau cemented carbide hniav, tab sis kuj rau kev txiav ib feem ntawm high-speed steel ib feem milling cutter los yog laum ntsis.
2. Kev txawj xaiv
(1) Cov cuab yeej indexable ntawm lub tshuab clamp yog cov cuab yeej nyiam rau NC machining. Yog li ntawd, cov khoom siv feem ntau muab qhov tseem ceeb rau cov khoom siv cemented carbide, thiab yog tias ua tau, sim xaiv cov hniav coated.
(2) Rau cov cuab yeej uas yuav cuam tshuam nrog kev sib tsoo tus kheej, cov khoom siv hlau ceev ceev feem ntau yog xaiv.
(3) Yog tias muaj kev xav tau tshwj xeeb, cov ntaub ntawv txiav cov cuab yeej superhard tuaj yeem txiav txim siab. Yog tias tsim nyog, cov txheej txheem yuav tsum tau ua ua ntej.
(4) Sim xaiv cov cuab yeej txiav nrog qee yam kev cuam tshuam hauv kev lag luam, thiab sim siv qee hom, uas yuav pab tau zoo rau kev ua haujlwm ntawm cov khoom siv txiav thiab muab kev ua si tag nrho rau kev ua haujlwm ntawm cov khoom siv txiav.
