1. Superalloy tig cov cuab yeej
Thaum tig superalloys nrog zoo tib yam high-ceev steel, lub cuab tam durability yog tsawg heev. Yog tias siv cov vanadium siab, carbon siab, aluminium thiab cobalt high-speed steel siv, cov cuab yeej siv tau ntev yuav kuj siab. Cemented carbide yog cov khoom siv tseem ceeb rau kev xa cov superalloys. YG cemented carbide nrog cov khoom zoo lossis ultra-fine yuav tsum raug xaiv.
Lub kaum sab xis ntawm cov cuab yeej cemented carbide feem ntau yog kwv yees li 10 degree, thiab nws yog 0 degree - 5 degree thaum tig tiav. Vim hais tias lub machinability ntawm cam khwb cia superalloys yog phem, lub rake lub kaum sab xis yuav tsum me me, txog 0 degree. Daim ntawv ntawm lub ntsej muag rake feem ntau yog linear arc thiab arc. Txhawm rau kom muaj cov chip tawg zoo dua. Kev ua haujlwm hardening ntawm superalloy yog qhov hnyav, yog li cov hniav yuav tsum tau ceev nrooj, thiab tsis muaj qhov tsis xws luag xws li sawtooth raug tso cai. Feem ntau, qhov tsis zoo chamfering tsis raug tso cai. Yog tias tsim nyog, nws me dua li txiav cov hlau zoo tib yam.
2. Txiav tsis
Tig superalloys kuj muaj kev txiav ceev sib xws rau qhov zoo tshaj plaws txiav kub. Kev txiav ceev ntawm kev txiav superalloy nrog carbide tig lub cuab yeej yog ({{0}}) m / min. Cam khwb cia superalloys siv qis txiav ceev, thaum deformed superalloys siv lub txiav ceev dua. Qhov tob txiav yog (3-7) mm thaum lub sij hawm roughing thiab (0.2-0.5) mm thaum zoo tig. Txhawm rau kom tsis txhob txiav cov txheej tawv tawv, tus nqi pub yuav tsum siab dua 0.1mm / r.
3. Txiav kua
Thaum tig superalloys, txiav cov kua dej yuav tsum tau siv, uas tuaj yeem txo qhov kub ntawm li 25 feem pua. Kev daws dej yuav tsum tau siv rau cov cuab yeej siv high-speed steel, thiab emulsion lossis siab siab txiav roj yuav tsum tau siv rau cemented carbide tej cuab yeej. Kev kub siab txiav cov kua uas muaj leej faj yuav tsum tsis txhob siv rau cov nickel puag superalloys kom tsis txhob muaj kev ntxhov siab corrosion thiab txo qaug zog.
4. Cov teeb meem xav tau kev saib xyuas
Feem ntau, cemented carbide yuav tsum tau siv los tig superalloy ntau npaum li qhov ua tau, thiab yuav tsum tau them nyiaj rau kev sib tsoo zoo ntawm cov cuab yeej ua kom lub ntsej muag roughness ntawm txhua lub cuab yeej nto tsawg dua {{0}}.4 μ m. Cov hniav yuav tsum tsis muaj serration thiab lwm yam tsis xws luag; Txhawm rau kom tsis txhob txiav cov txheej tawv tawv, qhov txiav qhov tob yuav tsum siab dua 0.2mm, thiab tus nqi pub yuav tsum siab dua 0.1mm/r; Txhawm rau kom cov hniav ntse thiab txo kev ua haujlwm nyuaj, cov cuab yeej blunt tus qauv yuav tsum tsawg dua 0.2 hli; Thaum txiav nrog cov cuab yeej siv high-speed steel, cov cuab yeej yuav tsum zam kom tsis txhob nyob ntawm qhov chaw txiav kom tsis txhob muaj qhov tawv tawv ntawm qhov txiav los ntawm kev sib zog, uas yuav ua rau muaj kev nyuaj rau kev txiav tom ntej.
