Kev Hloov Pauv Kev Ua Haujlwm Zoo ntawm Kev Txiav: Polycrystalline Cubic Boron Nitride (PCBN)
Cov phaj sib xyaw ua ke Polycrystalline cubic boron nitride (PCBN) yog cov khoom siv txiav ua haujlwm siab uas paub txog lawv qhov nyuaj tshwj xeeb, tiv taus kev hnav zoo heev, thiab ua kom muaj cua sov zoo heev. Cov yam ntxwv no ua rau PCBN zoo tagnrho rau kev ua haujlwm raug ntawm cov ntaub ntawv nyuaj xws li ceramics, cov hlau tawv, thiab cov hlau tawv. Piv rau cov cuab yeej txiav ib txwm muaj, Cov Cuab Yeej Pcbn muab kev txiav txim siab dua thiab kev ua haujlwm zoo dua, txhim kho kev tsim khoom thiab ua ib qho khoom muaj nqis tseem ceeb hauv kev lag luam tsim khoom.
Pcbn Composite PhajCov khoom siv no yog ua los ntawm cov hlau nplaum uas muaj zog, muab cubic boron nitride (CBN) micro-hmoov sib xyaw ua ke, thiab sintered nyob rau hauv qhov kub thiab txias siab. CBN muaj qhov nyuaj thib ob tsuas yog pob zeb diamond xwb, nrog rau kev ruaj khov thermal thiab kev tiv thaiv tshuaj lom neeg uas ntau dua li pob zeb diamond, ua rau nws yog tus neeg sib tw loj hauv kev siv cov hlau ua los ntawm hlau. Qhov no ua rau PCBN yog qhov kev xaiv tseem ceeb hauv kev siv cov cuab yeej abrasive thiab cov cuab yeej txiav.
Tus qauv tsim tshwj xeeb ntawm PCBN composite plates tsis yog tsuas yog muab qhov nyuaj thiab thermal stability zoo xwb tab sis kuj ua rau muaj kev tawv los ntawm cov hlau nplaum tawv, ua rau kev ua tiav ntxiv. Lawv qhov kev siv dav dav, suav nrog cov tshuab CNC siab heev, cov cuab yeej siv tshuab ua haujlwm tag nrho, thiab cov kab ua haujlwm ceev ceev. PCBN siv dav hauv kev ua cov hlau tawv, hlau cam khwb cia txias, cov hlau cuab yeej, thiab cov khoom forged tawv, maj mam hloov cov hlau nplaum tawv ib txwm muaj thiab cov cuab yeej ceramic thiab tshwm sim ua tus qauv tseem ceeb hauv kev lag luam cuab yeej txiav.
1. Qhov Xwm Txheej Kev Txhim Kho Tam Sim No ntawm PCBN Composite Phaj
Kev tsim cov cuab yeej PCBN tau nce qib ntau dua hauv thaj chaw xws li Tebchaws Europe, North America, thiab Nyiv Pooj, qhov twg lub kaw lus kev paub tab tau tsim. Cov khoom lag luam tau nce ntxiv los ntawm kev sib txawv, kev ua kom zoo dua, thiab kev ua haujlwm sib xws. PCBN composite plates los ntawm txawv teb chaws feem ntau ruaj khov ntawm cov kab uas hla tshaj 50 hli, nrog Element Six muab cov khoom lag luam nrog cov kab uas hla ntawm 57 hli thiab 101.6 hli ntawm cov CBN sintered lub cev ntshiab (AMB90), tswj kev hnav thiab kev ua haujlwm thermal sib txawv hauv 30% rau kev sib xws tshwj xeeb. DI thiab Sumitomo muab cov lus qhia ntawm 50.8 hli, 58 hli, thiab 64 hli, feem.
Boreas tau ua tiav tsim cov phaj PCBN sib xyaw ua ke uas muaj txoj kab uas hla 64 hli tom qab ntau xyoo ntawm kev tshawb fawb, nrog rau qhov loj me ntawm 2μm txog 15μm. Peb muab ntau dua 20 pawg sib txawv ntawm cov kev daws teeb meem tshwj xeeb kom tau raws li cov kev xav tau tshwj xeeb. Los ntawm kev xaiv Boreas 'PCBN composite plates, koj yuav muaj kev nce qib tseem ceeb hauv kev txiav ua haujlwm zoo thiab zoo!
