Thaum koj hnov 'Co 21', yog tias koj lub siab dhia ncaj nraim mus rau ib qho, rigidly txhais cov mis alloy, koj twb khiav tawm. Nyob rau hauv trenches ntawm peev casting thiab CNC machining, qhov kev xaiv no feem ntau ua rau muaj kev sib cav ntau dua li qhov tseeb. Nws tsis zoo li hu rau 304 stainless; nws yog shorthand, ib tug pib taw tes rau kev sib tham uas muaj cua sov ntau, kab kawm, thiab thaum kawg, kev ua tau zoo nyob rau hauv lub teeb los yog lub cuab tam. Kuv tau pom ntau RFQs qhov twg ib tug neeg tsuas yog nplawm 'Co 21' ntawm kev kos duab thiab xav kom muaj khawv koob, tsis nco qab tias cov khawv koob - lossis mob taub hau loj - yog nyob rau hauv cov ntsiab lus tshwj xeeb thiab lub peev xwm los txhais lawv.
Lub Spec yog ib kab pib, Tsis yog kab tiav
Wb tau qhob. Hauv peb txoj haujlwm ntawm Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), thov a Koj 21 feem ntau yog thaj av nrog kev siv rau qee yam xws li Haynes 21 lossis zoo ib yam li cobalt-chromium-molybdenum-tungsten nickel alloy. Thawj qhov peb ua tsis yog los hais; nws yog mus dissect. Qhov chaw ua haujlwm yog dab tsi? Puas yog rau cov roj turbine foob, lub hauv caug pob qij txha, lossis cov khoom siv siab hnav hauv kev ua tshuaj? Lub hauv paus chemistry tej zaum yuav yog ballpark, tab sis dab ntxwg nyoog - qhov txawv ntawm ib feem uas kav rau lub hlis thiab ib tug uas kav rau xyoo - yog nyob rau hauv lub thib ob txheej txheem thiab machining lub tswv yim.
Kuv nco qab txog qhov project ob peb xyoos rov qab rau aerospace MRO tus neeg siv khoom. Lawv xav tau ib tug hloov stator vane shroud, specifications Koj 21 sib npaug. Peb tau txais cov khoom kub-resistant cobalt alloy haum rau cov lus piav qhia dav. Lub plhaub pwm casting mus zoo, qhov tseeb qhov tseeb ntawm qhov taw tes. Tab sis tom qab-casting, thaum lub sij hawm kho cua sov kho, peb ntaus ib tug snag. Lub voj voog kev ntxhov siab peb tau siv, raws li tus qauv txheej txheem rau cov alloys zoo sib xws, tsis tau ua tiav qhov kev pom zoo carbide faib rau lawv qhov tshwj xeeb lub voj voog qaug zog. Ib feem dhau QA, tab sis hauv lawv lub rooj zaum sim, lub neej qaug zog yog li 15% qis dua lawv lub hom phiaj. Puas yog qhov ua tsis tiav? Tsis heev. Nws yog ib zaj lus qhia. Cov khoom yog technically Koj 21, tab sis daim ntawv thov thov a Koj 21 ntxiv rau hyper-specific thermal keeb kwm. Peb rov khiav lub batch nrog hloov kho, ntev stabilization anneal, thiab nws ntaus lub cim. Daim ntawv spec tsis hloov; peb cov txheej txheem tau ua.
Qhov no yog qhov uas lub khw qhov kev suav suav. Txhua tus tuaj yeem yuav cov khoom siv alloy. Tsis yog txhua tus muaj 30-khoom xyoo ntawm kev tsim qauv, pwm engineering, thiab kev kho cua sov tom qab uas lub chaw tsim khoom zoo li QSY accumulates. Koj kawm tau tias nrog cov superalloys no, cov machining tsis koj yuav siv rau cov hlau yuav cia li hlawv li inserts thiab ua hauj lwm-harden nto rau hauv oblivion. Koj xav tau kev txiav qis qis, tus nqi pub noj siab, kev teeb tsa nruj, thiab cov dej txias uas muaj ntau dua txog kev tswj qhov kub thiab txias dua li cov dej nyab xwb. Nws yog ib qho kev seev cev sib txawv.
Cov khoom siv thiab cov cuab yeej sib npaug
Lwm qhov kev mob taub hau yog cov khoom siv raw nws tus kheej. Hais Koj 21 tsis tau lees tias koj tau txais cov khoom siv los ntawm tib lub zeb, nrog tib lub impurity tswj, raws li qhov OEM. Peb ua hauj lwm nrog tshwj xeeb alloys xws li cobalt-based, thiab peb tau tsim kev sib raug zoo nrog mills peb ntseeg. Tab sis qee zaum tus neeg siv nyiaj txiag tau tsav lawv mus nrhiav cov khoom sib npaug los ntawm lwm qhov chaw. Qhov no yog ib qho kev pheej hmoo loj.
Peb tau muaj qhov xwm txheej nrog lub tshuab nqus tsev tsim khoom. Lawv xa lawv tus kheej los rau peb Koj 21 bar Tshuag rau CNC machining ntawm ib co hnyav-kev pab coj daim hlau. Cov ntawv pov thawj pom zoo rau ntawm daim ntawv. Tab sis thaum lub sij hawm machining, peb cov neeg ua hauj lwm pom cov chips tau coj txawv txawv - ntau stringy, tsawg nkig tshaj qhov xav tau. Cov cuab yeej hnav kuj txawv txav. Peb nres thiab khiav peb tus kheej spectrometry check. Cov chromium thiab molybdenum nyob rau hauv ntau yam, tab sis cov kab silicon thiab manganese tau tawm. Nws tsis yog qhov phem alloy, tab sis nws tsis yog qhov tseeb variant lawv lub twj tso kua mis tsim tau siv tau rau. Kev siv nws tuaj yeem ua rau qhov tsis tuaj yeem ua rau muaj kev cuam tshuam los yog xeb hauv thaj teb. Peb tau tshaj tawm nws, sib tham txog kev ua lag luam tawm, thiab lawv tau xaiv kom peb muab cov khoom siv los ntawm peb cov channel. Nws raug nqi ntau dua ua ntej tab sis tau txais kev cawmdim ntawm qhov ua tsis tiav.
Qhov no yog vim li cas ntawm peb lub xaib, tsi.com, peb hais txog kev sib koom ua ke ntawm casting thiab machining. Thaum peb tswj cov txheej txheem los ntawm cov hlau molten mus rau qhov tiav machined, peb tshem tawm qhov sib txawv loj. Cov Koj 21 (los yog xijpeem alloy) yog melted, cam khwb cia, tshav kub-kho, thiab machined nyob rau hauv ib lub ru tsev, nrog ib tug nruam xov ntawm cov txheej txheem tswj thiab lav. Cov ntaub ntawv los ntawm lub cub tawg casting qhia txog lub sijhawm kho cua sov, uas nyob rau hauv lem dictates lub tswv yim machining. Koj tsis tuaj yeem tau txais qhov ntawd los ntawm lub khw muag khoom uas tsuas yog cov tshuab yuav khoom.
CNC Machining: Qhov Kev Xav Tau Raws Li Txoj Cai
Machining cov alloys no yog qhov twg cov roj hmab ua tau raws li txoj kev. Nws tsis yog rau lub plawv. Koj tsis tuaj yeem cuam tshuam tus qauv kawg zeb ntawm nws. Peb tab tom tham txog cov cuab yeej carbide, cov geometries tshwj xeeb rau cov hlau kub kub, thiab qee zaum txawm tias CBN (cubic boron nitride) rau kev ua tiav. Lub teeb rigidity yog qhov tseem ceeb; ib qho kev sib tham yuav rhuav tshem qhov kev ncaj ncees ntawm qhov chaw uas yog qhov tseem ceeb rau kev qaug zog.
Ib qho kev nthuav dav uas feem ntau tau saib tsis pom yog lub xeev ntawm cov khoom ua ntej nws tsoo lub tshuab CNC. Rau Koj 21 castings, lawv puas nyob rau hauv lub xeev as-cam khwb cia, tshuaj kho, los yog tag nrho cov hnub nyoog? Lub hardness thiab ductility txawv heev. Peb ib zaug machined ib batch ntawm as-cam khwb cia Koj 21 vaj tse. Lub geometry yog complex, nrog nyias phab ntsa. Hauv qhov xwm txheej zoo li-cam khwb cia, cov khoom siv muaj qee qhov kev ntxhov siab seem thiab yog me ntsis softer. Machining mus zoo, tab sis tom qab peb tau ua qhov yuav tsum tau ua tom qab lub hnub nyoog ntawm kev ua kom tawv tawv, qee qhov ntawm cov ntu nyias tau nthuav tawm me ntsis kev cuam tshuam - ob peb txhiab ntawm ib nti, tab sis txaus kom tsis kam ua rau lub mating nto. Peb kawm. Tam sim no, rau qhov tseem ceeb-dimension qhov chaw, peb feem ntau ua ib tug ntxhib machining ua hauj lwm nyob rau hauv lub softer lub xeev, ces siv qhov kawg thaum tshav kub kub kev kho mob, ua raws li los ntawm ib tug lub teeb finishing pass mus rau lub geometry. Nws ntxiv ib kauj ruam, tab sis nws guarantees qhov tshwm sim.
Coolant tswv yim yog lwm lub ntsiab lus. Nrog rau cov alloys no, cua sov tsim ntawm qhov txiav ntug yog khaus. Koj yuav tsum tswj nws, tab sis kuj xav txog chemistry. Qee qhov kev ua tau zoo cobalt alloys tuaj yeem nkag siab rau qee yam sulfur lossis chlorine additives hauv cov coolants, uas yuav ua rau muaj kev ntxhov siab corrosion tawg tom qab. Peb siv nruab nrab pH, semi-synthetic coolants thiab tswj lawv meticulously. Nws yog ib qho me me hauv cov tswv yim loj, tab sis hauv kev lag luam no, cov ntsiab lus me me yog cov tswv yim loj.
Qhov zoo ntawm kev sib xyaw ua ke: Los ntawm Plhaub Pwm mus rau qhov kawg
Qhov no coj kuv rov qab mus rau lub hauv paus ntawm yuav ua li cas ib qho kev sib koom ua ke zoo li QSY tuav cov khoom zoo li Koj 21. Lub plhaub pwm casting txheej txheem peb siv yog qhov zoo rau kev ua tiav txoj hauv kev, ze-net-shaped geometries no cov khoom muaj nqis feem ntau xav tau. Thaum koj tab tom nrum ib qho kev sib txuam turbine los yog kev kho mob cog qauv hauv Koj 21, koj xav tau tsawg kawg machining Tshuag - tej zaum tsuas yog 0.5mm ib lub ntsej muag. Qhov no txuag lub sijhawm machining siab phem thiab cov khoom siv kim kim.
Tab sis kev koom ua ke yog ntau tshaj li kev txuag cov kauj ruam. Nws yog hais txog kev paub ntws. Pab pawg foundry paub tias Koj 21 casting rau ib tug tej phab ntsa thickness yuav muaj ib tug grain qauv. Lawv sib txuas lus nrog rau pab pawg CNC programming, leej twg tuaj yeem npaj lawv txoj hauv kev thiab clamping ua haujlwm nrog cov qauv ntawd, tsis tawm tsam nws. Pab neeg kho cua sov tau txais cov ntaub ntawv los ntawm ob sab kom zoo kho cov voj voog. Nws yog lub voj voog tawm tswv yim uas koj tsuas yog tau txais los ntawm kaum xyoo hauv ib lub ru tsev, ua haujlwm ntawm txhua yam los ntawm cam khwb cia hlau mus rau npib tsib xee-based alloys thiab, ntawm chav kawm, tsev neeg cobalt.
Kuv tau pom tej yaam num ua tsis tiav nyob rau hauv disjointed mov chains. Ib lub tuam txhab ua cov casting, lwm qhov kev kho cua sov, ib feem peb ntawm machining. Cov ntaub ntawv tau ploj. Tus machinist tau ib tug hardened, laus Koj 21 ib feem uas yog npau suav phem txiav thiab tsis paub yog vim li cas nws nyuaj heev. Lawv liam cov khoom. Tej zaum tus kws kho cua sov hnub nyoog nws ntawm qhov kub tsis raug rau tus kws kho tshuab qhov kev npaj cuab yeej. Thaum nws tag nrho cov kev sib txuas, cov teeb meem no yog tsim tawm ua ntej thawj pwm tseem nchuav.
Tshaj Tawm Txoj Cai: Ib Txoj Kev Pom Zoo
Yog li, dab tsi yog qhov takeaway ntawm Koj 21? Kho nws raws li qeb ua haujlwm, tsis yog khoom muag. Nws tus nqi tsis yog thaum koj xaj nws, tab sis thaum koj txhais tau tias nws yuav ua li cas, kho, thiab ua tiav. Kev vam meej ntawm ib feem hinges ntawm kev kho cov hlau alloy raws li txoj kab qhib hauv kev sib sib zog nqus kev sib tham txog kev ua tau zoo, ib puag ncig, thiab kev tsim khoom.
Rau cov engineers thiab cov neeg yuav khoom, kuv cov lus qhia yog saib dhau ntawm cov khoom siv ntawm cov duab kos. Koom nrog koj tus neeg muag khoom ntawm qhov txheej txheem. Nug: Dab tsi yog koj qhov kev paub dhau los nrog kev kho cua sov tom qab rau daim ntawv thov no? Koj ua li cas daws kev ntxhov siab ua ntej machining? Koj tus qauv machining parameter yog dab tsi rau tus mob no? Cov lus teb yuav qhia koj ntau tshaj li daim ntawv pov thawj zeb puas tau.
Thaum kawg, Koj 21 yog ib qho cuab yeej. Qhov zoo tshaj plaws muaj peev xwm rau hnav, kub, thiab corrosion kuj. Tab sis zoo li txhua yam cuab yeej precision, nws txoj kev ua tau zoo nyob ntawm qhov kev txawj ntawm tes, thiab qhov tob ntawm kev nkag siab, coj nws siv los ntawm cov khoom siv raw mus rau cov khoom tiav. Qhov ntawd yog cov alloy tiag tiag - ib qho kev sib xyaw ntawm cov tshuaj chemistry thiab cov khoom siv, cov khoom siv tswv yim.
