CBN txiav cuab yeejsbelongs rau ib hom superhard tej cuab yeej, uas yog tsim los siv ultra-siab kub thiab siab siab technology siv CBN hmoov raws li raw khoom thiab ib tug me me npaum li cas ntawm binder.Vim lub siab hardness ntawm CBN tej cuab yeej, nws yog heev haum rau ua cov ntaub ntawv uas hardness ntau tshaj HRC50 thiab muaj zog hnav tsis kam.
Cov khoom siv twg yog CBN?
CBN (cubic boron nitride) yog cov khoom siv superhard tsim tom qab pob zeb diamond, uas tau hloov los ntawm hexagonal boron nitride (dawb graphite) nyob rau hauv qhov kub thiab txias.CBN yog ib qho uas tsis yog-hlau boride, thiab nws hardness yog thib ob tsuas yog pob zeb diamond, deb tshaj li high-speed steel thiab hard alloy.Yog li ntawd, tom qab tau ua rau hauv cov cuab yeej, CBN yog qhov tsim nyog rau kev ua haujlwm ruaj khov nrog cov cuab yeej carbide.
Cov ntaub ntawv dab tsi yogCBN txiav cuab yeejhaum rau kev ua?
CBN tej cuab yeej siv tau los txiav cov ntaub ntawv xws li hardened steel (cov kabmob steel, pwm steel, thiab lwm yam), cam khwb cia hlau (grey cam khwb cia hlau, ductile hlau, siab chromium cam khwb cia hlau, alloy hnav-resistant cam khwb cia hlau, thiab lwm yam), high-speed steel, nyuaj alloy, high-temperature alloy, thiab lwm yam, thiab muaj zoo zoo nyob rau hauv ferrous hlau ua.
Nws yuav tsum raug sau tseg tias yog tias cov khoom siv yog hlau mos lossis tsis yog xim hlau, CBN cov cuab yeej txiav tsis haum rau kev ua.CBN tej cuab yeej raug pom zoo tsuas yog thaum cov khoom hardness mus txog ib theem (HRC> 50).
Feem ntauCBN daim kab xev Cov qauv tsim
Feem ntau hais lus, feem ntau siv cov cuab yeej txiav hauv kev tig machining feem ntau muaj cov qauv hauv qab no: ib qho CBN ntxig thiab welded CBN insert, ntawm cov welded CBN insert suav nrog ib qho welded insert thiab sib txuas welded insert.
(1) Integrated CBN insert.Tag nrho cov hniav yog sintered los ntawm CBN micro hmoov, nrog ntau yam txiav.Ob lub tswv yim sab sauv thiab sab qis tuaj yeem siv rau kev txiav, ua rau kev siv siab ntawm cov hniav dawb paug.Thiab cov hniav muaj zog dabtsi yog khoov siab thiab tuaj yeem tiv taus kev kub ceev nrog txiav qhov tob, haum rau kev nruam, tsis muaj zog sib cuam tshuam, thiab muaj zog sib cuam tshuam qhov chaw.Nws muaj kev siv dav thiab tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm ntxhib, semi precision, thiab precision machining.
(2) Integral welded CBN ntxig.Tag nrho lub cev nkag mus rau vuam daim ntawv muaj lub zog vuam siab thiab qhov nruab nrab qhov chaw, uas tuaj yeem hloov ncaj qha rau txheej txheej.Haum rau machining tej yam kev mob nrog ib tug tob ntawm <2 hli, tsis muaj zog intermittent thiab nruam machining ib puag ncig, ua tau raws li cov kev xav tau ntawm semi precision thiab precision machining.
(3) Composite welded CBN ntxig.Tom qab txiav, me me CBN sib xyaw blocks yog welded mus rau ib qho nyuaj alloy substrate los tsim ntau yam tig thiab tho hniav.Feem ntau, tsuas yog ib ntug yog muaj, feem ntau yog siv rau precision machining tej yam kev mob.
Tam sim no, CBN cov cuab yeej txiav tau siv dav hauv tsev thiab txawv teb chaws, tshwj xeeb tshaj yog rau kev txiav nyuaj rau cov khoom siv hauv kev lag luam xws li kev tsim tsheb (lub cav, crankshafts, nres discs, nres nruas, thiab lwm yam), mining machinery kev lag luam (rolling mortar phab ntsa, slurry twj, thiab lwm yam), bearing iav kev lag luam (hub bearings, slewing bearings, cua zog bearings, zog, thiab lwm yam), thiab kev lag luam rau cov menyuam (cam khwb cia hlau rollers, high-speed steel rollers, thiab lwm yam).
