Thaum muas Inconel® 718 round bars (UNS N07718), machining kev ua tau zoo tsuas yog ib qho tseem ceeb ntawm cov khoom siv nqi thiab ntawv pov thawj. Vim nws lub zog siab, ua haujlwm- tawv tawv, thiab qis thermal conductivity, Inconel 718 yog suav tias yog ib qho nyuaj -rau- tshuab superalloy.
Tsab ntawv xov xwm no muab kev hloov pauv ceev thiab pub rau Inconel 718 puag ncig bar, piav qhia tias kev kho cua sov cuam tshuam li cas rau kev ua haujlwm, thiab pab pawg neeg yuav khoom xaiv cov khoom tsim nyog kom txo tau cov nqi ua haujlwm thiab lub sijhawm ua haujlwm.
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 tsis yog - optimized
4. Txhim kho kev cia siab rau kev xa khoom thiab kev tswj cov khoom seem zoo dua
Inconel 718 Rods Machining yam ntxwv
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, tsis tshua muaj thermal conductivity (kwv yees li 11 W / m siab ntawm cov hlau stainless) thiab cov cuab yeej kub. qis- alloy steel, cov yam ntxwv no yuav tsum tau txiav nrawm dua, kev ruaj ntseg pub ntau dua, thiab cov cuab yeej clamping muaj zog dua.

Puas yog txoj kab uas hla loj dua cuam tshuam rau kev ua haujlwm ceev?
Yog lawm. Loj txoj kab uas hla Inconel 718 tuav feem ntau yuav tsum tau qis machining speeds vim muaj cua sov ntau, kev koom tes, thiab txiav quab yuam; Piv txwv li, kev txiav ceev yuav tsum tau txo los ntawm 20-40% piv nrog me me - txoj kab uas hla los tswj cov cuab yeej hnav thiab tswj qhov tseeb qhov ntev.
Inconel 718 puas tuaj yeem ua haujlwm ntawm kev kub ceev?
Inconel 718 tsis haum rau siab - machining ceev hauv cov qauv teeb tsa vim nws ua haujlwm hnyav - hardening thiab thermal conductivity tsawg; Kev txiav ceev raug txwv rau 20–40 m / min rau cov cuab yeej carbide, txawm tias cov cuab yeej siv siab heev thiab siab - lub tshuab ua kom txias tuaj yeem txhim kho cov khoom tsim tau yam tsis muaj kev cuam tshuam lub neej ntawm cov cuab yeej.
Kuv puas yuav tau yuav Inconel 718 round bars nyob rau hauv lub annealed los yog hnub nyoog - mob hnyav?
Xaiv annealed Inconel 718 yog tias koj cov txheej txheem cuam tshuam nrog kev ua haujlwm ntau lossis kev tsim, vim nws muaj qhov hardness qis dua (~ 200-250 HB) thiab ua haujlwm zoo dua; xaiv hnub nyoog-hardened ( nag lossis daus-hardened) 718 thaum daim ntawv thov yuav tsum muaj lub zog siab tshaj plaws, qhov twg tensile lub zog tuaj yeem ncav cuag 1,200–1,400 MPa, feem ntau siv hauv aerospace shafts, fasteners, thiab siab -load Cheebtsam.
