Cov yam ntxwv ua tau zoo tshaj plaws ntawm PCBN Composite Inserts

1. Kev Nyuaj Siab thiab Kev Tiv Thaiv Zoo Tshaj Plaws

Pcbn Composite Cov ntxig qhia txog qhov microhardness ntawm 2700–5000 HV, thib ob tsuas yog pob zeb diamond thiab siab dua li silicon carbide thiab txhuas oxide. Lawv qhov kev tiv thaiv kev hnav yog 50 npaug ntau dua li cov cuab yeej carbide, 30 npaug ntau dua li cov cuab yeej carbide coated, thiab 25 npaug ntau dua li cov cuab yeej ceramic. Qhov no ua rau lawv tsim nyog rau kev siv cov khoom ua haujlwm siab-hardness, ua rau muaj qhov zoo ntawm qhov chaw thiab ua kom yooj yim rau cov txheej txheem kho cua sov.

2. Kev Ruaj Ntseg Tshuaj Zoo heev

PCBN Cov cuab yeej ua tau zoo heev nyob rau hauv qhov kub ntawm 1200–1300 ° C, tiv taus cov tshuaj tiv thaiv acid thiab alkali, ua rau lawv zoo tagnrho rau kev siv cov hlau ferrous.

3. Kev Ruaj Ntseg Kub Siab Tshaj Plaws

PCBN Cov cuab yeej tuaj yeem tiv taus qhov kub ntawm 1400–1500 ° C, yuav luag ob npaug ntawm qhov kub ntawm pob zeb diamond. Lawv zoo meej rau kev siv tshuab ceev ceev ntawm superalloys thiab cov hlau tawv, nrog rau kev txiav ceev 4 txog 6 npaug sai dua li cov cuab yeej carbide.

4. Kev Ua Haujlwm Thermal Siab

Vim tias CBN muaj peev xwm ua kom sov tau zoo dua li carbide, nws thiaj li ua tau zoo dua li pob zeb diamond. Qhov kev ua kom sov zoo dua no ua rau qhov kub hauv thaj chaw txiav tsawg dua, ua rau lub cuab yeej siv tau ntev dua.

5. Kev Sib Txhuam Qis

Qhov sib txhuam coefficient ntawm PCBN thiab ntau yam khoom siv qis dua li ntawm carbide, txo qis thaum qhov ceev txiav nce ntxiv. Qhov no ua rau lub zog txiav tsawg dua thiab txo qhov lo rau ntawm cov chips.

Cov Kev Siv Dav Dav ntawm PCBN Composite Inserts

Cov yam ntxwv tshwj xeeb ntawm PCBN ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv cov khoom siv nyuaj, tshwj xeeb tshaj yog rau kev txiav ceev ceev. Nws daim ntawv thov npog ntau yam lag luam, suav nrog kev tsim tsheb, aerospace, thiab cov tshuab hnyav.

• Kev Faib Khoom Lag LuamKev lag luam tsheb suav txog 50.37%, tshuab hnyav rau 20.74%, thiab kev tsim twj tso kua mis rau 8.89%.
• Kev Faib Khoom SivCov hlau uas tau quenched muaj li ntawm 65%, thaum cov hlau cam khwb cia muaj li ntawm 28%.
• Kev Ua Haujlwm MachiningKev ua haujlwm tig yog 60%, nrog rau kev puab ntawm 32.5%.
• Cov Ntawv Thov Hloov50% ntawm PCBN siv yog rau kev hloov cov cuab yeej sib tsoo, 30% rau kev hloov cov cuab yeej carbide.

Piv txwv li, txij li thaum qhia txog Cov Ntawv Txuas Pcbn Xyoo 2005 rau kev siv tshuab ua cov discs nres hlau cam khwb cia, Beijing West Industries tau pom qhov ceev ntawm kev txiav ob npaug ntawm cov cuab yeej ceramic, nrog rau lub neej ntawm cov cuab yeej ntev dua 3 txog 4 npaug, ua rau muaj kev ua haujlwm ntau ntxiv thiab txo cov nqi.

Kev Xaiv thiab Kev Tsim Qauv

PCBN Cov cuab yeej siv no yog cov cuab yeej tshwj xeeb heev, xav tau cov qauv sib txawv raws li cov ntaub ntawv siv thiab cov txheej txheem ua haujlwm. Qhov muaj CBN ntau npaum li cas, qhov nyuaj ntawm cov cuab yeej, kev tiv taus kev hnav, thiab kev ua kom sov tau zoo dua. Feem ntau muab faib ua cov ntsiab lus CBN siab, nruab nrab, thiab qis, cov ntxig no yog tsim los ua kom tau raws li ntau yam kev xav tau ntawm kev siv tshuab.

• Cov Ntsiab Lus Siab (80%–95%): Zoo tagnrho rau cov hlau cam khwb cia, hmoov metallurgy, thiab superalloys.
• Cov Ntsiab Lus Nruab Nrab (60%–80%): Haum rau kev ua haujlwm hnyav ntawm cov hlau quenched.
• Cov Ntsiab Lus Tsawg (40%–60%): Zoo tshaj plaws rau kev ua haujlwm tas mus li nrog lub teeb thiab ceev ceev.

Raws li qhov yuav tsum tau ua kom raug thiab qhov zoo ntawm qhov chaw, CBN cov khoom muaj nyob rau hauv qhov loj me, nruab nrab, thiab me me kom ua tau raws li ntau yam kev xav tau ua tiav.

Nrog nws cov yam ntxwv ua tau zoo tshaj plaws, Boreas' PCBN Cov ntawv sib xyaw ua ke sawv tawm ua qhov kev xaiv zoo tshaj plaws rau kev ua cov ntaub ntawv nyuaj.
