Yuav ua li cas xaiv cemented carbide hniav?

Carbide insert yog cov cuab yeej siv dav siv rau kev ua haujlwm siab ceev. Cov khoom siv no yog tsim los ntawm cov hmoov hlau metallurgy thiab muaj cov tawv carbide thiab cov nplaum hlau mos. Tam sim no, muaj ntau pua qhov sib txawv ntawm WC-raws li cemented carbide, feem ntau siv cobalt ua cov ntawv khi, npib tsib xee thiab chromium kuj tseem muaj cov ntsiab lus sib txuas, thiab lwm cov ntsiab lus hlau kuj tuaj yeem ntxiv.

Kev xaiv ntawm cemented carbide hniav: Tig ntawm cemented carbide hniav yog cov txheej txheem tseem ceeb ntawm cemented carbide processing technology, tshwj xeeb tshaj yog nyob rau hauv kev lag luam machinery hnyav, kev xaiv cov cuab yeej tseem ceeb tshwj xeeb. Raws li cov khoom siv sib txawv, piv nrog cov machining zoo tib yam, hnyav tig muaj cov yam ntxwv ntawm kev txiav qhov tob, qis txiav ceev thiab qeeb pub ceev. Qhov nyiaj pub rau machining ntawm ib sab tuaj yeem ncav cuag 35-50 mm. Tsis tas li ntawd, vim qhov tsis zoo ntawm cov khoom ua haujlwm, kev faib tsis sib npaug ntawm cov khoom siv tshuab thiab qhov tsis sib xws ntawm cov khoom thiab lwm yam, qhov kev vibration ntawm machining nyiaj pab ua rau cov txheej txheem dynamic ntsuas kom noj ntau lub sij hawm txawb. thiab lub sijhawm pabcuam. Yog li ntawd, txhawm rau ua cov khoom hnyav thiab txhim kho kev tsim khoom lossis kev siv tus nqi ntawm cov cuab yeej siv tshuab, peb yuav tsum pib nrog nce lub thickness thiab pub tus nqi ntawm cov txheej txiav. Peb yuav tsum xyuam xim rau cov kev xaiv ntawm kev txiav tsis thiab cov hniav, txhim kho cov qauv thiab geometry ntawm cov hniav, thiab xav txog cov khoom ntawm cov hniav. Cov yam ntxwv muaj zog, yog li ua rau kev txiav tsis zoo thiab txo lub sijhawm ua haujlwm.

Cov ntaub ntawv siv hniav siv feem ntau suav nrog kev kub ceev steel, cemented carbide, ceramics, thiab lwm yam. Qhov loj txiav qhov tob feem ntau ncav cuag 30-50mm, thiab qhov nyiaj pub dawb tsis sib xws. Muaj ib txheej hardened rau ntawm qhov chaw ntawm lub workpiece. Nyob rau hauv qhov ntxhib machining theem, hniav hnav feem ntau tshwm sim nyob rau hauv daim ntawv ntawm abrasive hnav Lub txiav ceev yog feem ntau 15-20 m / min. Txawm hais tias tus nqi nrawm yog agglomeration ntawm cov nti, qhov kub siab ntawm kev txiav ua rau qhov chaw sib cuag ntawm cov nti thiab cov cuab yeej pem hauv ntej hauv cov kua hauv lub xeev, yog li txo kev sib txhuam thiab inhibiting agglomeration ntawm thawj tiam ntawm chips. Cov khoom siv hniav yuav tsum hnav-resistant thiab cuam tshuam resistant. Cov hniav ceramic muaj siab hardness, tab sis tsis tshua muaj zog dabtsi yog khoov thiab tsis tshua muaj kev cuam tshuam toughness. Nws tsis haum rau kev tig loj thiab muaj qhov tsis sib xws. Cemented carbide muaj ntau qhov zoo xws li "siab hnav tsis kam, siab dabtsi yog khoov lub zog, zoo cuam tshuam toughness thiab siab hardness", thaum cov kev sib txhuam coefficient ntawm cemented carbide yog tsawg, uas tuaj yeem txo qhov txiav quab yuam thiab txiav kub, thiab txhim kho cov kav ntev. ntawm cov hniav. Haum rau ntxhib machining ntawm cov ntaub ntawv siab hardness thiab hnyav tig. Nws yog qhov kev xaiv zoo tshaj plaws rau kev tig cov ntaub ntawv hniav.

Txhim kho txoj kev sib hloov ceev ntawm cemented carbide inserts hauv cov tshuab hnyav yog ib qho tseem ceeb los txhim kho kev tsim khoom thiab ua kom luv luv. Nyob rau hauv cov txheej txheem no, ib tug loj npaum li cas ntawm cov nyiaj seem yog txiav mus rau hauv ob peb strokes, thiab qhov tob ntawm txhua stroke yog heev me me. Qhov kev ua tau zoo ntawm cov hniav tuaj yeem txhim kho kev txiav ceev, yog li txhim kho kev tsim khoom, ncua kev pab cuam lub neej, thiab txo cov nqi thiab cov txiaj ntsig.
