Daim ntawv thov CBN / PCD cov cuab yeej nyob rau hauv thaj chaw ntawm lub nplai txoj hlua
Nyob rau hauv xyoo tsis ntev los no, nrog lub acceleration ntawm urbanization thiab nce ntawm khiav ceev, lub disc nres ntaus ntawv yog ntau dua siv. Raws li ib qho tseem ceeb hauv lub tshuab ntaus disk, lub hlwb tawg yog los xyuas kom muaj kev nyab xeeb thiab txhim khu kev txhuam ntawm txoj kev tsheb ciav hlau. ** Tshab, tshwj xeeb tshaj yog rau cov tsheb nrog luv luv qhov chaw nres tsheb nrug thiab luv luv kev sib tsoo, qhov uas yuav tsum tau ua rau cov pa disk ntau dua.
Tam sim no, cov khoom siv ntawm lub nplai txoj hlua yog muab faib ua ob pawg: hlau raws li cov ntaub ntawv hlau thiab cov ntaub ntawv sib xyaw, thiab cov hlau hlau raws li cov hlau nrig thiab steel tshuab. Cam khwb cia hlau cov ntaub ntawv tsuas yog grey cam khwb cia hlau, vermicular cam khwb cia hlau thiab hlau luam; steel yeem hlau cov ntaub ntawv yog cov hlau, hlau hlau casting hlau thiab hlau alloy steel.
Cov khoom sib xyaw nrog cov txheej txheem aluminium-based khoom thiab cov khoom siv carbon-carbon, thiab yog cov khoom tshiab uas muaj cov khoom zoo heev, uas yog cov khoom sib xyaw ntawm cov khoom matrix (hlau, tej hub) thiab lub zog (fiber, whisker, particle), thiab muaj suab nrov. Qhov kev vibration me me thiab cov khoom ua tau zoo tshaj plaws yog siab, tab sis cov txheej txheem ntau lawm yog demanding thiab kim.
Valin Super pom zoo siv cov cubic nitrite (BNK30 thiab BN-S300 qib) thiab pob zeb diamond cutters, uas tsuas tsis tau yooj yim ua kom pom qhov zoo ntawm lub pob tawg, tiam sis tsis zoo xwb kuj ua kom zoo dua qub. kev ua tau zoo.
Raws li ib tug pioneer hauv cov chaw ua haujlwm ntawm cov cuab yeej superhard, Valin tau ua haujlwm ntawm cubic boron nitride cov cuab yeej thiab cov qib high-diamonds rau cov khoom ntawm cov ntaub ntawv nyuab thiab cov khoom nyuab nyuab. Nyob rau hauv xyoo tas los, lub cubic boron nitride cov cuab yeej thiab cov pob zeb diamonds tau raug tsim los. Cov cuab yeej siv dav siv nyob rau hauv kev lag luam ntawm lub tsheb kev sib tsoo, kev kub nyhiab ultra-siab thiab kev txiav txim hnyav, kev kub ceev, thiab cov khoom siv tsis yooj yim. Ntawm lawv, BN-S300 qib thiab BNK30 qib raug siv los ua cov khoom siv rau kev ua haujlwm grey cam khwb cia hlau khiav nres cov discs. Kev ua tiav zoo.
BN-S300 qib yog ib lub cuab yeej CBN monolithic uas ua los ntawm kev ua kom pom tseeb, muaj ntaub qhwv huv siab tom qab kub thiab kub siab sintering. CBN cov ntsiab lus yog siab li 97%, thiab lub **** muaj qhov sib xyuam zoo li qub nrog Hualing ** yam ntxwv. Cov ntaub ntawv siv tshuab, cov hniav muaj lub siab ceev thiab uniformity, thiab cov hardness yog tusyees HV3600. Nws muaj zoo heev hnyav thiab ntug zog, uas ua rau nws muaj lub cuab tam ntev hauv kev nruam thiab cuam tshuam txiav.
BNK30 qib txais cov sib xyaw ntawm cov khoom nano-nplua thiab cov khoom purity-nano CBN, thiab CBN polycrystals tsis muaj kev pabcuam (tsis muaj cemented carbide) (substrate) sintered hauv kub thiab siab; nws cov hardness siab dua, CBN particle loj yog finer. Nws yog ib qho tshwj xeeb tshaj yog tsim rau kev kub ceev, uas tuaj yeem nrhiav tau zoo thiab ruaj khov ua haujlwm zoo. Nyob rau tib lub sijhawm, qhov CBN polycrystalline block yuav kho nrog rau tej yam nyuaj alloy substrate los ntawm lub tshuab nqus cov tshuab nqus tsev kom tsim tau cov cuab yeej ntawm ntau yam qauv.
Rau cov choj brake discs, Valin super zog pom cov pob zeb diamond tool CDW010 thiab cov ntaub ntawv CDW025. Qhov saum toj ob cov ntaub ntawv yog sintered los ntawm cov khoom cua pob zeb diamond microcrystals hauv siab thiab siab siab. Vim yog qhov sib ntxiv ntawm cov txheej txheem sintering, lub pob zeb diamond muaj kev ua siab tawv thiab muaj zog, thiab khoov lub zog, uas muab cov txheej txheem tshiab coj los ua kev sib xyaw nres kev ua haujlwm.
