Vim li cas thiaj txiav ceev thiab pub tus nqi tseem ceeb heev thaum yuav Inconel 718 bar Tshuag?
Rau kev yuav cov kws tshaj lij, machinability yog ib qho tseem ceeb raws li cov khoom siv kho tshuab. Thaum machining Inconel 718 bar Tshuag, tsis raug txiav ceev thiab pub tus nqi tuaj yeem ua rau 30% mus rau 50% nce hauv cov cuab yeej hnav, ntev machining cycles, thiab ntau dua tag nrho cov nqi.
Kev nkag siab txog kev txiav txim siab pom zoo pab cov neeg yuav khoom mus rau:
1. Xaiv cov khoom tsim nyog bar (kev daws teeb meem annealed lossis hnub nyoog-hardened)
2. Kwv yees cov nqi machining tiag
3. Zam cov neeg muag khoom uas muab cov ntaub ntawv uas tsis yog - optimized
4. Txhim kho kev cia siab rau kev xa khoom thiab kev tswj cov khoom seem zoo dua
Machining Yam ntxwv ntawm Inconel 718 Rods
Inconel 718 (UNS N07718) yog nag lossis daus-nickel hardened-raws li superalloy yam ntxwv los ntawm: siab yield zog (Ntau tshaj los yog sib npaug rau 1,000 MPa tom qab kev laus kho), tseem ceeb ua hauj lwm hardening, thermal conductivity tsawg (kwv yees li 11 W / m siab concentration ntawm cov cuab yeej), thiab tej cuab yeej.
Tus neeg yuav khoom ceeb toom:
Muab piv rau cov hlau tsis muaj steel lossis qis- alloy steel, cov yam ntxwv no yuav tsum tau txiav nrawm dua, ntau dua kev ruaj ntseg, thiab cov cuab yeej clamping muaj zog dua.

Puas yog Inconel 718 nyuaj rau tshuab?
Yog lawm, Inconel 718 yog qhov tsis zoo rau lub tshuab vim nws lub zog siab, ua haujlwm ceev- cov khoom siv tawv tawv, thiab cov thermal conductivity tsawg, uas ua rau muaj kev txiav txim siab, hnav cov cuab yeej ceev, thiab cov cua sov tsim, xav tau cov tshuab muaj zog, cov cuab yeej tshwj xeeb, qeeb nrawm, thiab txiav hnyav.
Dab tsi txiav ceev yog pom zoo rau tig Inconel 718 bar?
Rau txoj kev tig Inconel 718, pom zoo txiav ceev sib txawv nrog cov cuab yeej, feem ntau yog li ntawm 40-55 m/min (130-180 SFM) nrog coated carbides rau cov qauv kev ua haujlwm, tab sis tuaj yeem ncav cuag 400-600 m / min nrog cov cuab yeej siab heev xws li cBN rau kev ua haujlwm siab, qis dua (30 m / min).
Kuv puas yuav tau yuav cov tshuaj -annealed lossis hnub nyoog Inconel 718 bar?
Koj yuav tsum yuav cov hnub nyoog Inconel 718 ( nag lossis daus hardened ) yog tias koj xav tau lub zog siab tshaj plaws thiab hardness rau koj qhov ua tiav, zam kev tshaj tawm -machining tshav kub kho; xaiv txoj kev daws teeb meem-annealed 718 yog tias koj xav tau kev ua kom yooj yim dua thiab npaj ua lub hnub nyoog- kho koj tus kheej tom qab, tab sis cia siab tias yuav muaj zog dua zaum kawg tom qab kev laus.
