Kev paub txog kev tungsten carbide machine riam khoom
Carbide cov khoom siv yog cov feem ntau ntawm kev siv cov cuab yeej kev kub ceev (HSM) cov cuab yeej siv, cov khoom siv no yog ua los ntawm hmoov hlau metallurgy txheej txheem, los ntawm cov tawv carbide (feem ntau yog tungsten carbide WC) cov khoom thiab qhov zoo ntawm cov khoom siv hlau daim ntawv cog lus. Tam sim no, muaj ntau pua hom tungsten steel hniav txawv txav ntawm WC cemented carbide, lawv feem ntau yog siv cobalt (C o) li pob, nickel (NI) thiab chromium (Cr) yog cov siv feem ntau siv, ntxiv rau koj kuj ntxiv tau lwm cov ntsiab lus.
Hardness thiab toughness
Cov ntaub ntawv WC-co thiab carbide cov tawv nqaij muaj qhov tshwj xeeb hauv kev mob siab thiab kev muaj zog. Tungsten carbide (WC) nws tus kheej muaj lub siab tawv (siab dua corundum los yog alumina), thiab nws qhov kev tsis tshua muaj zog thaum lub sijhawm kub ua haujlwm nce. Txawm li cas los, nws tsis muaj txaus toughness, uas yog qhov tseem ceeb rau kev txiav txim kev ua tau zoo. Cov zaub mov noj yog tsim los siv kev siv zog ntawm tungsten carbide thiab txhim kho nws lub zog. Cov neeg siv hlau daim ntawv cog lus rau tungsten carbide ua ke, yog li ntawd cov ntaub ntawv muaj ntau tshaj qhov nyuaj ntawm high speed steel, nyob rau tib lub sij hawm, rau withstand txiav quab yuam nyob rau hauv feem ntau machining.
Milling txheej txheem
Tungsten carbide hmoov yog tau los ntawm carburizing tungsten (W) hmoov. Cov khoom ntawm tungsten carbide hmoov (tshwj xeeb tshaj yog nws cov qoob loj) tsuas yog txiav txim siab los ntawm qhov loj ntawm cov hmoov tungsten hmoov thiab qhov kub thiab lub sij hawm ntawm kev saib xyuas. Tshuaj tiv thaiv kab mob kuj tseem ceeb, thiab cov ntsiab lus ntawm cov zaub yuav tsum nyob tas mus li (ze rau qhov kev piv txwv ntawm 6.13 feem pua ntawm qhov hnyav). Yuav kom tswj tau cov hmoov me me los ntawm cov txheej txheem tom ntej, ib qho me me ntawm vanadium thiab / los yog chromium yuav muab ntxiv ua ntej carburizing.
Hardness thiab toughness
WC-Co cemented carbide muaj qhov tshwj xeeb hauv kev mob siab thiab muaj zog. Tungsten carbide (WC) nws tus kheej muaj lub siab tawv (siab dua corundum los yog alumina), thiab nws qhov kev tsis tshua muaj zog thaum lub sijhawm kub ua haujlwm nce. Txawm li cas los, nws tsis muaj txaus toughness, uas yog qhov tseem ceeb rau kev txiav txim kev ua tau zoo. Carbide cov khoom siv kom siv tungsten carbide ntawm kev kub siab, thiab kom nws lub zog muaj zog, neeg yuav siv hlau nyiaj tungsten carbide ua ke, yog li ntawd cov ntaub ntawv muaj ntau tshaj qhov nyuaj ntawm kev kub ceev, tib lub sij hawm, rau withstand txiav quab yuam hauv feem ntau machining. Tsis tas li ntawd, nws muaj peev xwm tiv tau lub siab kub ua los ntawm kev kub ceev machining.
