Carbide hniav yog tsim los ntawm cov hlau alloy, high-speed steel, edged steel, tag nrho cov hlau, tungsten steel thiab lwm yam ntaub ntawv. Siv cov txheej txheem kev kho cua sov tshwj xeeb thiab cov cuab yeej siv kho tshuab tuaj txawv teb chaws, ntau yam kev ua tau zoo ntawm cov hniav hlau ua rau cov tshuab slitting ncav cuag cov qauv kev lag luam hauv tebchaws.
Carbide inserts yog ib hom high-speed machining txiav inserts dav siv nyob rau hauv machinery ntau lawm kev lag luam. Carbide yog tsim los ntawm cov hmoov metallurgy txheej txheem thiab muaj cov tawv carbide (feem ntau tungsten carbide WC) hais thiab softer hlau binders. Kev sib xyaw ua ke, siv cov khoom siv carbide tuaj yeem ua kom zoo dua qhov roughness rau cov neeg siv. Cov hniav hlau muaj zog tiv thaiv thiab cov hniav yuav tsis tawg sai sai, ua rau nws muaj kev nyab xeeb rau kev siv.
Tam sim no, muaj ntau pua ntawm cov hniav hlau nrog cov sib txawv, feem ntau siv cobalt ua tus neeg sawv cev sib txuas. Nickel thiab chromium kuj tseem siv cov khoom sib txuas, thiab qee qhov lwm yam alloying tseem tuaj yeem ntxiv. Vim li cas thiaj muaj ntau lub horns nyuaj? Yuav ua li cas alloy insert manufacturers xaiv txoj cai insert cov ntaub ntawv rau ib tug tej kev lag luam?
Cov khoom siv ntawm cov cemented carbide inserts yog cov yam tseem ceeb uas cuam tshuam rau qhov zoo ntawm qhov chaw, txiav efficiency thiab ntxig cov kev pab cuam lub neej. Thaum txiav, txiav ib feem ntawm cov hniav yog lub luag haujlwm ncaj qha rau kev txiav ua haujlwm. Qhov kev ua tau zoo ntawm cov hniav hlau feem ntau yog nyob ntawm cov khoom siv uas ua rau txiav ib feem ntawm cov hniav, qhov ntsuas geometric ntawm qhov txiav thiab xaiv thiab tsim cov qauv ntawm cov hniav.
Kev tsim khoom thiab cov hniav durability ntawm carbide hniav thaum txiav, hniav noj thiab cov nqi ua haujlwm, kev ua tiav thiab qhov zoo ntawm qhov chaw, thiab lwm yam, txhua yam nyob ntawm qhov loj ntawm cov khoom tsim nyog ntawm cov hniav. Xaiv cov ntaub ntawv alloy hniav yog ib qho tseem ceeb ntawm kev tsim thiab xaiv cov hniav.
Hardness yog cov yam ntxwv tseem ceeb uas cov khoom siv carbide yuav tsum muaj. Rau cov khoom siv carbide kom tshem tawm cov chips los ntawm cov khoom ua haujlwm, nws qhov hardness yuav tsum siab dua qhov hardness ntawm cov khoom ua haujlwm. Qhov thib ob yog qhov kub tsis kam ntawm carbide insert. Thaum tshav kub kub tsis kam yog qhov taw qhia tseem ceeb ntawm kev txiav kev ua haujlwm ntawm cov khoom siv ntxig. Nws yog hais txog kev ua haujlwm ntawm cov khoom siv hniav kom muaj qee qhov hardness, hnav tsis kam, lub zog thiab toughness nyob rau hauv qhov kub thiab txias. Nyob rau hauv ntau zaus, tiav workpieces yuav tsum tau txheej. Cov txheej muab lubricity thiab hardness ntawm carbide insert, thiab muab ib tug diffusion barrier rau lub substrate los tiv thaiv oxidation thaum raug kub. Lub alloy ntxig substrate yog qhov tseem ceeb rau kev ua haujlwm ntawm txheej txheej.
