Cov txheej txheem txiav nyiaj rau kwv yees li 90% ntawm kev ua haujlwm machining.Cov cuab yeej yog "cov hniav" ntawm cov cuab yeej siv tshuab, uas cuam tshuam ncaj qha rau kev ua haujlwm ntawm kev tsim khoom.Txiav yog hais txog kev txiav cov khoom siv ntau dhau los ntawm qhov chaw ua haujlwm, kom ntseeg tau tias lub workpiece geometry, qhov tseeb qhov tseeb, qhov zoo ntawm qhov chaw thiab lwm yam ntawm cov qauv tsim ntawm txoj kev machining, suav txog li 90% ntawm tag nrho cov machining workload.Txiav yog feem ntau ua tiav los ntawm cov cuab yeej siv tshuab txiav, thiab cov cuab yeej yog cov khoom siv tseem ceeb, raws li "cov hniav" ntawm cov cuab yeej siv tshuab, nws qhov zoo ncaj qha cuam tshuam rau kev tsim cov tshuab tsim tshuab, kev tsim khoom thiab cov khoom zoo.Txiav cov cuab yeej nce toj rau cov khoom siv raw khoom, cov khoom siv qis siv hauv kev lag luam loj.Siv cov cuab yeej tseem ceeb tshaj plaws carbide ua piv txwv, raws li cov ntaub ntawv ua tiav tuaj yeem muab faib ua: steel, stainless hlau, cam khwb cia hlau, tsis-ferrous hlau, tshav kub-resistant alloy, hardened steel, thiab lwm yam. Upstream rau cov ntaub ntawv raw ( tungsten carbide, cobalt hmoov, tantalum niobium khoom tov, thiab lwm yam) manufacturers, downstream daim ntawv thov teb yog concentrated nyob rau hauv kev tsim kev lag luam, mas siv nyob rau hauv tsheb thiab maus taus, tshuab cuab yeej, machinery, pwm, engineering machinery thiab lwm yam teb, aerospace, tub rog, kev kho mob machinery thiab lwm yam kev lag luam kuj muab kev siv dav dua thiab qhov chaw hloov pauv rau cov cuab yeej carbide.
Dab tsi yog cov yam ntxwv ntawm cov cuab yeej carbide?
1.high hardness: Carbide cuab yeej yog ua los ntawm carbide nrog siab hardness thiab melting point (paub tias yog ib theem nyuaj) thiab hlau binder (paub tias yog binding theem) los ntawm hmoov metallurgy txoj kev, nws hardness yog 89 ~ 93HRA, ntau dua siab ceev steel. , ntawm 5400C, qhov hardness tseem tuaj yeem ncav cuag 82 ~ 87HRA, thiab kev kub ceev steel chav kub hardness (83 ~ 86HRA) tib yam.
2. dabtsi yog khoov lub zog thiab toughness: lub zog dabtsi yog khoov ntawm zoo tib yam nyuaj alloy yog nyob rau hauv qhov ntau ntawm 900 ~ 1500MPa.Qhov siab dua cov ntsiab lus ntawm cov hlau binding theem, qhov siab dua qhov khoov lub zog.Thaum cov ntsiab lus binder zoo ib yam, YG (WC-Co).Lub zog ntawm cov hlau yog siab dua YT (WC-Tic-Co) alloy, thiab lub zog txo nrog qhov nce ntawm TiC cov ntsiab lus.Cov khoom siv tawv tawv yog ib yam khoom siv tawv tawv, nws qhov cuam tshuam toughness ntawm chav tsev kub tsuas yog 1/30 ~ 1/8 ntawm HSS.
3. Zoo hnav tsis kam.Kev txiav ceev ntawm cov cuab yeej carbide yog 4 ~ 7 npaug siab dua li cov hlau ceev ceev, thiab lub cuab yeej lub neej yog 5 ~ 80 npaug siab dua.Kev tsim pwm, ntsuas cov cuab yeej, lub neej tshaj cov cuab yeej hlau hlau 20 ~ 150 npaug siab dua.Muaj peev xwm txiav 50HRC lossis cov khoom siv nyuaj.
