Thaum koj hnov 'alloy precision machining', feem ntau lub siab dhia ncaj nraim mus rau lub tshuab-qhov tseeb 5-axis CNC, lub sub-micron tolerances. Qhov ntawd yog ib feem ntawm nws, paub meej, tab sis nws yog qhov yooj yim. Zaj dab neeg tiag tiag pib ntev ua ntej lub toolpath, nrog rau cov khoom nws tus kheej. Kuv tau pom ntau txoj haujlwm stumble vim tias ib tus neeg tau xaj ib qho thaiv ntawm Inconel 718 lossis Hastelloy C-276 xav tias nws tsuas yog 'nyuaj hlau' xwb. Tsis yog. Nws yog ib tug tsiaj nyaum sib txawv kiag li, thiab machining nws yog kev sib tham, tsis yog ib qho lus txib.
Lub Foundation: Nws pib nrog Casting
Koj tsis tuaj yeem tham txog machining kab txawv alloys yam tsis tau tham txog yuav ua li cas koj tau txais cov Tshuag. Ib tug zoo meej billet los ntawm ib lub zeb yog ib yam, tab sis ntau complex Cheebtsam, tshwj xeeb tshaj yog rau kev lag luam xws li li qub los yog turbo machinery, pib li castings. Qhov no yog qhov uas kev sib raug zoo ntawm cov foundry thiab lub tshuab khw tau txais qhov tseem ceeb. Kev ua haujlwm tsis zoo, nrog cov qauv nplej tsis sib xws lossis zais micro-porosity, yuav ua rau koj cov cuab yeej puas thiab koj lub sijhawm txawm tias koj lub tshuab ua haujlwm zoo npaum li cas.
Kuv nco qab ib txoj hauj lwm ob peb xyoos dhau los, cov twj tso kua mis nyob hauv duplex stainless. Cov ntawv luam tau hu rau alloy precision machining ntawm txhua lub ntsej muag sealing. Cov castings tuaj ntawm tus neeg muag khoom tsom rau tus nqi, tsis yog txheej txheem. Visually, lawv tau zoo. Tab sis thaum lub sij hawm thawj hnyav roughing dhau, peb ntaus ib tug xuab zeb inclusion. Ces lwm. Cov inserts tau chipping zoo li vwm. Peb tau siv sijhawm ntau los tshuaj xyuas thiab vuam / kho cov castings dua li qhov ua tau zoo. Zaj lus qhia yog lim hiam: koj lub peev xwm machining yog capped los ntawm koj cov khoom zoo. Qhov no yog vim li cas kev ua haujlwm sib xyaw ua ke muaj ntug. Lub tuam txhab uas tswj ob qho tib si casting thiab machining, zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), tuaj yeem kho cov txheej txheem los ntawm qhov pib. Lawv peb lub xyoos nyob rau hauv lub plhaub thiab peev casting txhais tau tias lawv tab tom tsim ib feem rau manufacturability los ntawm cov qauv theem, uas yog lub taub hau loj pib rau lub tshuab.
Qhov kev sib koom ua ke no tsis yog sib tham rau tshwj xeeb alloys. Nrog cobalt los yog npib tsib xee-raws li alloys, uas feem ntau cam khwb cia rau hauv cov duab nyob ze-net kom txuag tau tus nqi txaus ntshai ntawm cov khoom siv khib nyiab, qhov kev ncaj ncees casting yog txhua yam. Ib qho kev puas tsuaj sab hauv dhau los ua qhov av mines rau $ 200 kawg zeb.
Lub Tooling Dance: Tsis muaj Universal Solution
Tsis muaj khawv koob 'super-alloy' ntxig qib. Leej twg hais tias yog muag ib yam dab tsi. Machining nickel-based alloy zoo li Inconel 625 yog lub ntiaj teb sib txawv los ntawm tackling ib tug cobalt-chrome alloy zoo li Stellite 6. Cov qub ua hauj lwm-hardens zoo li vwm, xav tau tas li, aggressive kev koom tes nyob rau hauv lub hardened txheej. Cov tom kawg yog ntau ntxiv txog abrasive hnav; nws mam li maj mam zom koj cov ntug txiav mus rau ib nub.
Peb kawm qhov no los ntawm kev sim siab thiab ua yuam kev. Rau ib pawg ntawm lub rooj zaum hauv Stellite, peb pib nrog peb cov qauv kev ua haujlwm siab carbide rau cov nickel alloys. Cov cuab yeej siv sijhawm li 15 feeb. Hloov mus rau qib nrog ib qho nyuaj, ntau dua abrasion-resistant substrate thiab ib tug sharper ntug npaj. Lub neej tripled. Nws suab yooj yim hauv kev rov qab los, tab sis qhov kev hloov ntawd yuav tsum muaj kev hloov pauv hauv kev xav: peb tsis tau txiav, peb zoo li kev tswj fracturing. Coolant siab thiab xa khoom yog qhov tseem ceeb ntawm no thiab. Ib tug dhau-spindle system tsis yog khoom kim heev; Nws yog tib txoj hauv kev los tiv thaiv kev kub ntxhov thiab ntxuav cov chips abrasive.
Kev teeb tsa tseem ceeb npaum li lub cuab yeej. Rigidity tsis yog ib qho kev pom zoo xwb; nws yog txoj cai. Ib qho kev sib tham nyob rau hauv ib tug cobalt alloy yuav tsis tsuas yog ua kom tiav, nws yuav pib tawg uas yuav propagate. Peb siv cov cuab yeej monolithic nkaus xwb rau kev ua tiav, tsis muaj chucks. Tus nqi ntxiv yog tsis cuam tshuam piv rau scrapping ib feem uas twb muaj 20 teev ntawm machining sunk rau hauv nws.
Speed vs. Stability: Kev Ua Lag Luam Nyob Mus Ib Txhis
Cov phau ntawv pub thiab ceev rau cov ntaub ntawv no feem ntau... optimistic. Los yog lawv nyob nraum rau cov xwm txheej zoo tagnrho, zoo meej clamping, cov cuab yeej siv tshuab tshiab. Hauv pem teb khw, koj hu nws rov qab. Kuv xav khiav ntawm 70% ntawm qhov theoretical SFM thiab tau txais kev kwv yees, txhim khu kev qha 8-teev cov cuab yeej lub neej tshaj li thawb rau qhov siab tshaj plaws tshem tawm hlau thiab muaj lub cuab yeej ua tsis zoo thaum 3 AM. Consistency trumps raw ceev hauv precision machining. Lub hom phiaj yog txhawm rau ntaus qhov thib kaum (.0001) kev ua siab ntev rau ntawm lub bore, tsis yog kom yeej kev sib tw ceev.
Human Factor: Data and Instinct
CNC machining yog automated, tab sis khiav alloys tsis yog. Tus programmer yuav tsum nkag siab txog cov khoom siv tus cwj pwm, tsis yog G-code xwb. Tus neeg teb xov tooj yuav tsum tau mloog qhov kev txiav-lub suab ntawm cov nickel alloy pib ua hauj lwm-harden muaj ib qho tshwj xeeb, lub suab nrov nrov uas txhais tau tias koj yuav tsum tau kho, tam sim no. Koj saib cov xim nti thiab daim ntawv. Blue chips ntawm stainless? Kub dhau lawm. Ntev, stringy chips ntawm Inconel? Koj lub chip breaker tsis ua haujlwm; npaj rau noog lub zes thiab rov txiav.
Qhov no yog qhov uas kev paub los ntawm cov khoom siv dav dav them tawm. Lub khw uas tau ua txhua yam los ntawm cam khwb cia hlau mus rau superalloys tsim lub tsev qiv ntawv ntawm instincts. Lawv paub tias 316L stainless muaj qhov nyiam 'cov pos hniav' ntawm lub cuab yeej, xav tau lub kaum sab xis sib txawv. Lawv paub tias ua ntej cua sov lub titanium alloy casting ua ntej machining tuaj yeem txo cov kev ntxhov siab thiab tiv thaiv kev cuam tshuam tom qab ua haujlwm. Qhov no tsis yog ib txwm nyob hauv phau ntawv; nws yog nyob rau hauv kev sib koom kev paub nyob rau hauv pem teb. Lub tuam txhab zoo li QSY, nrog nws keeb kwm hauv cam khwb cia hlau, hlau, stainless hlau, thiab tshwj xeeb alloys, tej zaum yuav muaj qhov tob ntawm pab pawg neeg kev paub tau tsim dua 30 xyoo. Nws yog hom khoom uas koj tsis tuaj yeem yuav nrog lub tshuab tshiab.
Cov ntaub ntawv yog qhov tseem ceeb, tab sis nws yog tus kheej. Peb khaws cov ntawv ua haujlwm rau txhua txoj haujlwm alloy - tsis yog qhov kev ua tiav kawg nkaus xwb, tab sis kev sim ua tsis tiav ib yam nkaus. Sim ntxig qib XYZ, ua tsis tiav ntawm 0.015 DOC vim chipping. Daim ntawv ntawd txuag tus txiv neej tom ntej ib txhiab nyiaj hauv kev siv cuab yeej thiab plaub teev ntawm lub sijhawm poob.
Precision nyob rau hauv cov ntsiab lus: Koj Yuav Ua Li Cas Tiag?
Precision tsis yog tus lej paub daws teeb. Nws yog txhais los ntawm qhov ua haujlwm. Lub turbine hniav tej zaum yuav muaj ib tug kam rau ua stack-up ntawm nws airfoil profile uas yog insane, tab sis lub mounting flange tej zaum yuav kuj xoob. Lub valve tivthaiv lub precision yog tag nrho hais txog cov sealing nto thiab lub bore concentricity; lwm yam nta tej zaum yuav tsis tshua tseem ceeb. Koj faib koj lub tswv yim machining thiab nyiaj txiag kam rau ua raws li.
Kuv tau ua haujlwm ntawm cov khoom siv rau lub twj tso kua mis tshuaj, lub impeller loj hauv Hastelloy C-22. Lub qhov ntev ntev ntawm lub vanes tau nruj, tab sis qhov kev sib tw tiag tiag yog qhov ua tiav ntawm cov kab hauv sab hauv. Ib qho micro-pitting los ntawm kev tswj cov cuab yeej tsis zoo yuav dhau los ua qhov chaw rau corrosion thiab tawg pib. Peb siv sij hawm ntau dua rau kev ua kom zoo dua rau kev ua tiav dhau los ntawm tag nrho cov voj voog roughing. Cov CNC machining lub tswv yim tau tsim rov qab los ntawm qhov kawg ntawm qhov yuav tsum tau muaj kev ncaj ncees.
Qhov no yog qhov uas kev koom ua ke ntawm casting thiab machining qhia nws tus nqi dua. Yog hais tias lub foundry tuaj yeem nrum smoother nto nyob rau hauv cov txheej txheem sab hauv, lub tshuab ua haujlwm yuav ua tiav. Yog tias lawv ua tsis tau, tej zaum koj yuav tau saib EDM lossis tes polishing, uas ua rau tus nqi thiab ncua sij hawm sib nrug. Nws yog qhov teeb meem systems.
Kab hauv qab: Tswj qhov sib txawv
Thaum kawg ntawm hnub, ua tiav alloy precision machining yog hais txog kev tswj ntau qhov sib txawv raws li koj tuaj yeem ua tau. Koj pib los ntawm kev tswj xyuas qhov zoo thiab qhov sib xws ntawm cov khoom siv raw-txawm nws yog ib qho khoom lag luam lossis ib qho kev ua haujlwm nyuaj. Koj tswj cov txheej txheem los ntawm kev xaiv cov cuab yeej thiab cov kev ntsuas raws li cov kev coj ua tshwj xeeb, tsis yog cov ntsiab lus dav dav. Koj tswj tau ib puag ncig nrog kev teeb tsa nruj thiab ua kom txias zoo. Thiab koj tswj tau qhov tshwm sim nrog cov neeg paub txog uas tuaj yeem txhais cov ntaub ntawv thiab hnov mob.
Nws yeej tsis muaj teeb meem-thiab-tsis nco qab-nws ua haujlwm. Muaj ib txwm muaj qhov sib txawv ntawm cov alloy tshiab, ntau qhov geometry, kev ua siab ntev dua. Cov khw muag khoom kawg, cov uas tuaj yeem ntseeg tau xa cov khoom siv los ntawm cov ntawv luam tawm rau cov khoom siv cobalt, yog cov uas hwm tag nrho cov saw hlau, los ntawm cov yaj mus rau qhov kawg tshuaj ntsuam xyuas. Lawv tsis yog cov tshuab xwb; lawv muaj tus txheej txheem. Thiab cov txheej txheem ntawd, hais ncaj ncees, yog qhov koj them nyiaj tiag tiag.
