Cov cuab yeej cemented carbide feem ntau siv rau hauv cov cuab yeej CNC machining. Hauv qee lub tebchaws, ntau tshaj 90% ntawm cov cuab yeej tig thiab ntau tshaj 55% ntawm cov cuab yeej milling yog ua los ntawm cemented carbide. Tsis tas li ntawd, cemented carbide feem ntau siv los tsim cov cuab yeej dav dav xws li cov laum thiab cov tshuab txiav ntsej muag. Kev siv cemented carbide kuj tseem nce ntxiv hauv cov cuab yeej nyuaj xws li reamers, end mills, nruab nrab thiab loj modulus iav txiav rau kev ua cov hniav tawv, thiab broaches. Kev txiav zoo ntawm cov cuab yeej cemented carbide yog 5 txog 8 npaug ntawm cov cuab yeej hlau ceev ceev (HSS). Tus nqi ntawm cov hlau tshem tawm ib chav ntawm cov tungsten yog li 5 npaug ntau dua li HSS. Yog li ntawd, kev siv cemented carbide dav dav ua cov khoom siv cuab yeej yog ib txoj hauv kev zoo tshaj plaws los siv cov peev txheej kom zoo, txhim kho kev tsim khoom txiav, thiab txhim kho cov txiaj ntsig kev lag luam.
Kev faib tawm ntawm cov khoom siv cemented Carbide
Raws li cov tshuaj lom neeg tseem ceeb, cemented carbide tuaj yeem muab faib ua tungsten carbide-based cemented carbide thiab titanium carbonitride (Ti(C,N))-based cemented carbide, raws li qhia hauv Rooj 3-1.
Cov cemented carbide raws li tungsten carbide muaj xws li:
Tungsten-cobalt (YG)
Tungsten-cobalt-titanium (YT)
Nrog ntxiv cov carbides tsis tshua muaj (YW)
Txhua hom muaj nws tus kheej qhov zoo thiab qhov tsis zoo. Cov carbides ntxiv suav nrog tungsten carbide (WC), titanium carbide (TiC), tantalum carbide (TaC), niobium carbide (NbC), thiab lwm yam, nrog cobalt (Co) yog cov hlau binder feem ntau siv.
Cov cemented carbide uas yog titanium carbonitride feem ntau yog TiC (qee qhov nrog lwm cov carbides lossis nitrides ntxiv), nrog molybdenum (Mo) thiab nickel (Ni) ua cov hlau binder feem ntau siv.
Raws li qhov loj ntawm cov noob, cemented carbide tuaj yeem faib ua:
Cov cemented carbide ib txwm muaj
Cov cemented carbide zoo
Cov cemented carbide uas zoo heev
Raws li GB/T 2075—2007, cov cim ntawm tsab ntawv yog raws li nram no:
HW: Cov cemented carbide uas tsis tau coated feem ntau muaj cov tungsten carbide (WC) nrog cov noob loj ntawm ≥1μm
HF: Cov cemented carbide uas tsis tau coated feem ntau muaj cov tungsten carbide (WC) nrog cov noob me me ntawm <1μm
HT: Cov cemented carbide uas tsis tau coated feem ntau muaj titanium carbide (TiC) lossis titanium nitride (TiN) lossis ob qho tib si (tseem hu ua cermet)
HC: Cov cemented carbides uas tau hais los saum toj no nrog ib txheej
Lub Koom Haum Thoob Ntiaj Teb rau Kev Txheem (ISO) faib cov cemented carbides txiav ua peb pawg:
Chav Kawm K (K10 txog K40):
Sib npaug rau Suav teb YG chav kawm (feem ntau yog tsim los ntawm WC-Co)
P chav kawm (P01 txog P50):
Sib npaug rau Tuam Tshoj YT chav kawm (feem ntau yog tsim los ntawm WC-TiC-Co)
Chav Kawm M (M10 txog M40):
Sib npaug rau Suav teb YW chav kawm (feem ntau yog tsim los ntawm WC-TiC-TaC (NbC) -Co)
Cov qib ntawm txhua pawg yog sawv cev los ntawm tus lej ntawm 01 thiab 50, qhia txog cov hlau sib xyaw los ntawm qhov nyuaj tshaj plaws mus rau qhov tawv tshaj plaws, rau kev xaiv hauv ntau yam txheej txheem txiav thiab cov xwm txheej machining rau cov khoom siv sib txawv. Yog tias tsim nyog, ib tus lej nruab nrab tuaj yeem ntxig rau ntawm ob tus lej faib sib ze, xws li P15 ntawm P10 thiab P20, lossis K25 ntawm K20 thiab K30, tab sis tsis pub ntau tshaj ib. Hauv cov xwm txheej tshwj xeeb, tus lej faib P01 tuaj yeem faib ntxiv los ntawm kev ntxiv lwm tus lej sib cais los ntawm ib qho lej lej, xws li P01.1, P01.2, thiab lwm yam, kom paub qhov txawv ntawm kev hnav tsis kam thiab tawv ntawm cov khoom siv rau kev ua tiav.
Kev Ua Tau Zoo ntawm Cov Khoom Siv Cemented Carbide
1. Kev Nyuaj Siab: Cemented carbide muaj ntau cov carbides tawv (xws li WC, TiC), ua rau nws qhov nyuaj dua li cov khoom siv hlau ceev ceev. Qhov nyuaj dua ntawm cemented carbide, qhov zoo dua nws qhov kev tiv thaiv hnav, uas feem ntau siab dua li cov hlau ceev ceev.
Qhov siab dua cov cobalt binder theem cov ntsiab lus, qhov qis dua qhov hardness ntawm cov hlau.
Vim tias TiC nyuaj dua li WC, cov hlau WC-TiC-Co muaj qhov nyuaj dua li cov hlau WC-Co. Cov ntsiab lus TiC ntau dua, qhov nyuaj dua.
Ntxiv TaC rau hauv WC-Co alloys ua rau kom tawv ntxiv li ntawm 40 txog 100 HV; ntxiv NbC ua rau nws tawv ntxiv li ntawm 70 txog 150 HV.
2. Lub zog Lub zog flexural ntawm cemented carbide tsuas yog li 1/3 txog 1/2 ntawm cov khoom siv hlau ceev ceev.
Qhov siab dua cov cobalt cov ntsiab lus, qhov siab dua lub zog ntawm cov hlau.
Cov hlau uas muaj TiC muaj zog tsawg dua li cov uas tsis muaj TiC; qhov ntau TiC, qhov tsawg zog.
Ntxiv TaC rau hauv WC-TiC-Co cemented carbide ua rau nws lub zog flexural nce thiab ua rau cov ntug txiav tsis kam rau chipping thiab tawg. Thaum cov ntsiab lus TaC nce ntxiv, lub zog qaug zog kuj zoo dua.
Lub zog compressive ntawm cemented carbide yog 30% txog 50% siab dua li ntawm cov hlau ceev ceev.
