Cemented carbide cov cuab yeej tseem ceeb hauv CNC machining cov cuab yeej. Hauv qee lub tebchaws, ntau dua 90% ntawm cov cuab yeej tig thiab ntau dua 55% ntawm cov cuab yeej milling yog ua los ntawm cov cemented carbide. Tsis tas li ntawd, cemented carbide feem ntau yog siv los tsim cov cuab yeej siv dav dav xws li kev xyaum thiab lub ntsej muag milling cutters. Kev siv cov cemented carbide tseem nce ntxiv hauv cov cuab yeej nyuaj xws li reamers, kawg mills, nruab nrab thiab loj modulus iav cutters rau machining hardened hniav nto, thiab broaches. Qhov kev ua tau zoo ntawm cov cuab yeej cemented carbide yog 5 mus rau 8 npaug ntawm cov cuab yeej siv high-speed steel (HSS). Tus nqi ntawm cov hlau tshem tawm ib chav tsev ntawm cov ntsiab lus tungsten yog li 5 npaug ntau dua li ntawm HSS. Yog li ntawd, dav siv cemented carbide ua cov khoom siv yog ib txoj hauv kev zoo tshaj plaws los siv cov peev txheej zoo, txhim kho kev tsim khoom, thiab txhim kho cov txiaj ntsig kev lag luam.
Kev faib tawm ntawm Cemented Carbide Tool Materials
Raws li cov tshuaj lom neeg muaj pes tsawg leeg, cemented carbide tuaj yeem muab faib ua tungsten carbide-based cemented carbide thiab titanium carbonitride (Ti(C, N))-raws li cemented carbide, raws li qhia hauv Table 3-1.
Tungsten carbide-based cemented carbide suav nrog:
Tungsten-cobalt (YG)
Tungsten-cobalt-titanium (YT)
Nrog ntxiv tsawg carbides (YW)
Txhua hom muaj nws qhov zoo thiab qhov tsis zoo. Cov carbides ntxiv muaj xws li tungsten carbide (WC), titanium carbide (TiC), tantalum carbide (TaC), niobium carbide (NbC), thiab lwm yam, nrog cobalt (Co) yog cov feem ntau siv hlau binder theem.
Titanium carbonitride-raws li cemented carbide feem ntau muaj TiC (qee nrog lwm cov carbides lossis nitrides ntxiv), nrog molybdenum (Mo) thiab npib tsib xee (Ni) raws li cov txheej txheem siv hlau binder.
Raws li cov nplej loj, cemented carbide tuaj yeem faib ua:
Ordinary cemented carbide
Fine-grained cemented carbide
Ultrafine-grained cemented carbide
Raws li GB / T 2075-2007, cov ntawv cim yog raws li nram no:
HW: Uncoated cemented carbide feem ntau muaj tungsten carbide (WC) nrog cov nplej loj ntawm ≥1μm
HF: Uncoated cemented carbide feem ntau muaj tungsten carbide (WC) nrog cov nplej loj ntawm <1μm
HT: Uncoated cemented carbide feem ntau muaj titanium carbide (TiC) lossis titanium nitride (TiN) lossis ob qho tib si (tseem hu ua cermet)
HC: Cov cemented carbide tau hais los saum toj no nrog txheej txheej
Lub koom haum International rau Standardization (ISO) faib cov cemented carbides rau hauv peb pawg:
Qib K (K10 txog K40):
Sib npaug rau Tuam Tshoj cov chav kawm YG (tsuas yog tsim los ntawm WC-Co)
Qib P (P01 txog P50):
Sib npaug rau Tuam Tshoj cov chav kawm YT (tsuas yog tsim los ntawm WC-TiC-Co)
Chav Kawm M (M10 txog M40):
Sib npaug rau Tuam Tshoj YW chav kawm (tsuas yog tsim los ntawm WC-TiC-TaC(NbC)-Co)
Txhua pawg qib yog sawv cev los ntawm tus lej ntawm 01 thiab 50, qhia txog cov khoom sib txawv ntawm qhov nyuaj tshaj plaws mus rau qhov nyuaj tshaj plaws, rau kev xaiv hauv ntau cov txheej txheem txiav thiab kev ua haujlwm rau cov khoom sib txawv. Yog tias tsim nyog, tus lej nruab nrab tuaj yeem muab tso rau ntawm ob qhov kev faib cov lej sib txuas, xws li P15 ntawm P10 thiab P20, lossis K25 ntawm K20 thiab K30, tab sis tsis pub ntau tshaj ib qho. Hauv cov xwm txheej tshwj xeeb, P01 kev faib cov lej tuaj yeem muab faib ntxiv los ntawm kev ntxiv lwm tus lej sib cais los ntawm tus lej lej, xws li P01.1, P01.2, thiab lwm yam, txhawm rau paub qhov txawv ntawm qhov hnav tsis kam thiab tawv ntawm cov khoom siv rau kev ua tiav.
Kev ua tau zoo ntawm Cemented Carbide Tool Materials
1. HardnessCemented carbide muaj ntau qhov nyuaj carbide (xws li WC, TiC), ua rau nws hardness ntau dua li cov khoom siv hlau ceev. Qhov siab dua qhov hardness ntawm cemented carbide, qhov zoo dua nws hnav tsis kam, uas feem ntau yog siab dua li ntawm high-speed steel.
Qhov siab dua ntawm cobalt binder theem cov ntsiab lus, qhov qis hardness ntawm alloy.
Txij li TiC nyuaj dua WC, WC-TiC-Co alloys muaj zog dua li WC-Co alloys. Cov ntsiab lus TiC ntau dua, qhov nyuaj dua.
Ntxiv TaC rau WC-Co alloys nce hardness li ntawm 40 txog 100 HV; Ntxiv NbC nce nws los ntawm 70 rau 150 HV.
2. Lub zog flexural zog ntawm cemented carbide tsuas yog hais txog 1/3 txog 1/2 ntawm cov khoom siv high-speed steel.
Qhov siab dua cov ntsiab lus cobalt, qhov siab dua lub zog ntawm cov hlau.
Alloys uas muaj TiC muaj zog qis dua cov uas tsis muaj TiC; TiC cov ntsiab lus ntau dua, qhov qis zog.
Ntxiv TaC rau WC-TiC-Co cemented carbide tsub kom nws lub zog flexural thiab txhim khu kev txiav ntug kev tiv thaiv rau chipping thiab tawg. Raws li TaC cov ntsiab lus nce, qaug zog lub zog kuj txhim kho.
Lub zog compressive ntawm cemented carbide yog 30% mus rau 50% siab dua li ntawm high-speed steel.
3. ToughnessThe toughness ntawm cemented carbide yog qis dua li ntawm high-speed steel.
Alloys uas muaj TiC muaj zog dua li cov uas tsis muaj TiC; Raws li TiC cov ntsiab lus nce, toughness txo.
Hauv WC-TiC-Co alloys, ntxiv qhov tsim nyog ntawm TaC tuaj yeem ua kom tawv tawv li ntawm 10% thaum tuav cov cua sov thiab hnav tsis kam.
Vim nws qhov qis zog, cemented carbide tsis haum rau cov xwm txheej uas muaj kev cuam tshuam los yog kev vibrations, tshwj xeeb tshaj yog nyob rau hauv qis txiav ceev uas adhesion thiab chipping yog hnyav dua.
4. Thermal Physical PropertiesThermal conductivity ntawm cemented carbide yog kwv yees li 2 mus rau 3 npaug ntau dua li cov hlau ceev ceev.
Txij li cov thermal conductivity ntawm TiC qis dua li ntawm WC, WC-TiC-Co alloys muaj qis thermal conductivity tshaj WC-Co alloys. Cov ntsiab lus TiC ntau dua, cov thermal conductivity tsawg dua.
5. Thaum tshav kub kub ResistanceCemented carbide muaj cua sov ntau dua li cov hlau kub ceev thiab tuaj yeem ua kev txiav ntawm 800 mus rau 1000 ° C nrog kev ua haujlwm zoo rau cov yas deformation ntawm qhov kub thiab txias.
Ntxiv TiC nce qhov kub thiab txias hardness. Txij li TiC lub softening kub yog siab tshaj WC's, lub hardness ntawm WC-TiC-Co alloys txo qeeb qeeb nrog kub dua WC-Co alloys. Qhov ntau TiC thiab cobalt tsawg, qhov tsawg dua.
Ntxiv TaC los yog NbC (nrog kub softening ntau dua li TiC) ntxiv kom kub-kub hardness thiab lub zog.
6. Anti-Adhesion PropertiesThe adhesion kub ntawm cemented carbide yog siab dua li ntawm high-speed steel, muab nws zoo dua tiv thaiv adhesion hnav.
Cobalt qhov adhesion kub nrog hlau yog qis dua WC's; Raws li cov ntsiab lus cobalt nce, adhesion kub txo.
TiC's adhesion kub yog siab tshaj WC's, yog li WC-TiC-Co alloys muaj adhesion kub (kwv yees li 100 ° C siab dua) tshaj WC-Co alloys. TiO2 tsim ntawm qhov kub thiab txias thaum txiav txo adhesion.
TaC thiab NbC muaj qhov kub adhesion ntau dua li TiC, txhim kho cov khoom tiv thaiv adhesion. TaC's affinity nrog workpiece cov ntaub ntawv tsuas yog ib feem rau ob peb feem kaum ntawm WC's.
7. Chemical StabilityThe hnav tsis kam ntawm cov cuab yeej cemented carbide yog ze rau lawv lub cev thiab tshuaj lom neeg ruaj khov ntawm kev ua haujlwm kub.
Qhov kub ntawm oxidation ntawm cemented carbide yog siab dua li ntawm high-speed steel.
TiC qhov kub ntawm oxidation yog ntau dua li WC's, yog li WC-TiC-Co alloys nce oxidation tsawg dua ntawm qhov kub siab tshaj WC-Co alloys; TiC ntau dua, muaj zog oxidation tsis kam.
TaC's oxidation kub kuj tseem siab dua WC's, thiab alloys nrog TaC thiab NbC tau txhim kho tsis kam mus rau high-kub oxidation. Txawm li cas los xij, cov ntsiab lus cobalt ntau dua ua rau oxidation yooj yim dua.
