Thaum tib neeg tham txog 'hom precision machining', lawv feem ntau tsuas yog sau cov txheej txheem xws li milling, tig, sib tsoo. Qhov ntawd tsis yog lawm, tab sis nws nco lub ntsiab lus. Zaj dab neeg tiag tiag yog hais txog kev xaiv cov txheej txheem tsim nyog rau cov khoom siv hauv koj txhais tes thiab kev ua siab ntev ntawm cov duab kos, thiab cov txheej txheem no feem ntau yuav tsum ua haujlwm li cas. Kuv tau pom ntau tus qauv tsim uas qhia meej qhov chaw tiav tsuas yog ua tiav los ntawm kev sib tsoo, tab sis qhov geometry ua rau clamping rau kev sib tsoo yuav luag tsis yooj yim sua. Qhov ntawd yog qhov tiag 'hom' tuaj rau hauv kev ua si - tsis yog cov tshuab xwb, tab sis qhov sib lawv liag thiab lub hom phiaj.
Nws pib nrog Casting: Lub Foundation rau Machining
Qhov no yuav zoo li pom tseeb, tab sis koj tsis tuaj yeem tham txog precision machining hauv peb cov ntsiab lus yam tsis tau pib nrog lub casting. Ib tug phem casting guarantees ib tug machined ib feem ntawm lub taub hau. Kuv tau ua haujlwm nrog cov neeg muag khoom uas kho cov casting thiab machining raws li lub ntiaj teb sib cais, thiab qhov tshwm sim yog ib txwm muaj nqi ntxiv thiab sijhawm. Ib lub tuam txhab uas tau txais txoj cai no, xws li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ua haujlwm txawv. Nrog rau ntau tshaj 30 xyoo nyob rau hauv ob qho tib si casting thiab machining, lawv to taub hais tias ib tug zoo plhaub pwm los yog peev casting tsis yog hais txog cov duab; nws yog hais txog kev muab qhov zoo ib yam, lub hauv paus suab nrog qhov kev ntxhov siab tsawg kawg nkaus. Machining ib feem ntawm lawv cov cobalt-raws li alloy peev casting yog ib qho kev sib txawv dua li pib nrog lub wrought bar Tshuag - cov machining tsis, cov cuab yeej hnav, txhua yam hloov.
Lawv txoj hauv kev nrog cov ntaub ntawv zoo li cov hlau tsis zoo lossis 316 stainless hlau yog xav txog kev ua haujlwm los ntawm cov qauv theem. Cov kaum sab xis, cov kab sib faib, lawv txhua tus tau muab tso nrog tus kws kho qhov muag. Qhov no tsis yog theoretical; nws yog hais txog kev zam qhov xwm txheej uas koj tab tom sim ua kom hnyav txiav ntawm cov phab ntsa nyias nyias, ua rau muaj kev vibration thiab ua kom tiav. Kuv nco qab txog lub twj tso kua mis vaj tsev qhov project qhov pib casting tsim muaj qhov tseem ceeb sealing nto nyob rau hauv ib qho chaw uas yuav luag unmachinable. Nws tsuas yog vim lub foundry (ib qho nrog kev sib xyaw ua ke zoo li koj xav pom ntawm tsi.com) tau koom nrog thaum ntxov uas peb rov tsim kho lub hauv paus kom tso cai rau cov cuab yeej siv tau zoo.
Kev sib koom ua ke yog qhov tseem ceeb. Lawv qhov tshwj xeeb hauv ob lub plhaub pwm casting thiab CNC machining nyob rau hauv ib lub ru tsev txhais tau tias cov txheej txheem kev npaj yog kev koom ua ke. Lub casting tsis yog ib qho khoob xwb; nws yog thawj, cov kauj ruam tseem ceeb hauv precision machining sequence. Qhov no tshem tawm ntau qhov kev kwv yees thiab kev thuam-hloov uas tshwm sim thaum nrhiav los ntawm cov neeg muag khoom sib cais.
CNC Machining: Cov neeg ua haujlwm thiab nws cov nuances
Tam sim no, mus rau qhov kev tshwm sim tseem ceeb. Thaum peb hais CNC machining, nws yog lub tsev teev ntuj dav. Rau cov ntim siab, qhov yooj yim dua los ntawm lawv cov castings, multi-axis milling chaw yog qhov mus-rau. Tab sis lo lus 'precision' ntawm no yog txheeb ze. Tuav ± 0.05mm ntawm lub steel bracket yog ib yam; ua tiav ± 0.005mm ntawm lub rooj zaum valve rau ib qho tshwj xeeb alloy yog lwm tus tsiaj nyaum nkaus.
Kev xaiv ntawm 3-axis, 4-axis, lossis 5-axis tsis yog hais txog qhov nyuaj; nws feem ntau hais txog kev txo kev teeb tsa. Txhua zaus koj rov kho ib feem, koj qhia txog qhov yuam kev. Rau ib txoj kev peev-cam khwb cia turbine tivthaiv hauv npib tsib xee-raws li alloy, peb ib txwm xaiv rau lub tshuab 5-axis kom tiav qhov chaw tseem ceeb hauv ib qho kev teeb tsa. Tus nqi ib teev yog siab dua, tab sis qhov kawg qhov tseeb thiab qhov sib xws yog qhov zoo dua. Kuv tau ua qhov yuam kev ntawm kev sim txuag nyiaj los ntawm kev sib faib cov haujlwm ntawm 3-axis tshuab, thiab qhov kev ua siab ntev sib sau ua ke yog npau suav phem los kho.
Ces muaj tig. Rau kev sib hloov qhov chaw los ntawm lawv cov cam khwb cia hlau lossis steel Tshuag, CNC tig nrog cov cuab yeej nyob yog qhov tseem ceeb. Tab sis precision tig rau stainless hlau, tshwj xeeb tshaj yog cov qib nyuaj, yog ib qho kev seev cev ntawm kev ceev, pub, thiab coolant. Kev sib xyaw ua ke tsis raug ua rau kev ua haujlwm nyuaj, uas tom qab ntawd rhuav tshem koj lub cuab yeej thiab rhuav tshem qhov kev ncaj ncees ntawm qhov chaw. Nws yog kev paub tactile - mloog kev txiav, saib cov xim nti thiab daim ntawv. Tsis muaj phau ntawv qhia programming tuaj yeem qhia qhov ntawd.
Qhov Kev Sib Tw Ua tiav: Qhov tseeb Precision tshwm sim
Qhov no yog qhov twg ntau qhov kev sib tham ntawm hom precision machining poob luv. Lawv kho milling / tig raws li qhov kawg. Hauv kev muaj tiag, rau cov khoom uas xav tau qhov tseeb tiag-xav tias hydraulic manifolds, bearing seats, lossis sealing nto-uas tsuas yog theem ib nrab tiav. Kev sib tsoo yog qhov ua khawv koob tshwm sim. Tab sis txawm tias kev sib tsoo muaj nws hom: nto sib tsoo, cylindrical sib tsoo, tsis muaj kev sib tsoo.
Peb muaj ib qhov project rau ib tug ncej los ntawm hardened steel. Txoj kev tig tau los ze, tab sis cov kabmob haum yuav tsum tau ua tiav Ra 0.2μm thiab qhov siab ntev ntawm ob peb microns. Qhov ntawd yog cylindrical sib tsoo thaj chaw. Qhov kev ua kom yuam kev yog qhov sib lawv liag: ntxhib tig, kho cua sov, ua tiav tig, ces grind. Yog tias koj sim zom cov khoom siv ntau dhau tom qab kev kho cua sov, koj tsim kom muaj cua sov ntau dhau thiab muaj kev pheej hmoo rau tempering ntawm qhov chaw. Nws yog ib qho kev sib npaug.
Qee zaum, txawm tias kev sib tsoo tsis txaus. Rau qhov chaw zoo nkauj heev lossis tshem tawm cov pob txha pob txha sab laug los ntawm kev sib tsoo, honing lossis lapping tuaj. Kuv nco qab lub valve spool peb tau ua uas khaws cia tom qab sib tsoo. Qhov teeb meem yog me ntsis, sub-micron-theem waviness ntawm lub cylindrical nto. Txoj kev daws yog ib tug ceev honing txheej txheem. Nws tsis hloov qhov ntev npaum li cas, tab sis nws hloov qhov kev ntxhib los mos txaus rau kev ua haujlwm zoo. Qhov no yog qhov nuance: precision tsis yog tus lej xwb; nws yog tus yam ntxwv zoo rau daim ntawv thov.
Cov khoom yog tus Dictator
Koj tsis tuaj yeem cais hom machining ntawm cov khoom. Ua haujlwm nrog QSYcov ntaub ntawv zoo li cam khwb cia hlau yog zam txim; nws tshuab zoo nkauj, tsim cov chips luv luv, thiab zoo rau cov cuab yeej. Hlau yog tawv dua tab sis kwv yees. Stainless hlau, tshwj xeeb tshaj yog cov qib austenitic, yog gummy thiab nquag ua-up ntug. Koj xav tau cov cuab yeej ntse, cov kaum sab xis zoo, thiab tej zaum muaj txheej txheej sib txawv.
Tab sis qhov kev sib tw tiag tiag yog lawv qhov tshwj xeeb: cobalt-based thiab nickel-based alloys. Cov no yog cov khoom npau suav phem rau ib tus kws kho tshuab tsis tau npaj. Lawv ua hauj lwm-harden sai heev, yog heev abrasive, thiab lawv thermal conductivity yog tsis zoo, yog li tshav kub concentrates ntawm tej ntug. Rau cov no, txhua yam hloov pauv. Kev nrawm qis dua, cov khoom noj yuav siab dua kom tau raws li cov txheej txheem ua haujlwm hnyav, thiab kev xaiv qib carbide yog qhov tseem ceeb. Peb kawm txog txoj kev nyuaj uas siv tus qauv TiAlN coated kawg zeb ntawm ib feem ntawm Stellite tsuas yog ua rau cov cuab yeej yaj thiab cov khoom pov tseg. Hloov mus rau qib tshwj xeeb nrog cov ntsiab lus cobalt siab thiab sib txawv geometry yog tib txoj kev. Qhov no yog qhov chaw muab khoom siv, zoo li 30 xyoo tau sau tseg Qingdao Qiangsenyuan Technology Co., Ltd., ua tangible-lawv tej zaum yuav hlawv los ntawm cov cuab yeej txaus kom paub tias ua haujlwm li cas.
Coolant tswv yim ua qhov tseem ceeb ntawm no. High-pressure, los ntawm cov cuab yeej coolant tsis yog khoom kim heev; Nws yog ib qho tsim nyog los rhuav tshem cov chips thiab nqa cov cua sov mus. Qee lub sij hawm, rau kev ua tiav ntawm cov superalloys no, peb tseem yuav siv qhov tsawg kawg nkaus kom muaj nuj nqis lubrication (MQL) kom ua tiav qhov zoo dua qhov tiav yam tsis muaj thermal shock. Tsis muaj ib qho loj-haum-tag nrho.
Muab Tag Nrho Ua Ke: Lub Ntiaj Teb Tiag Tiag
Yog li, tus txheej txheem precision machining zoo li cas rau qhov nyuaj? Cia peb ua ib tug hypothetical tab sis tiag tiag twj tso kua mis impeller nyob rau hauv duplex stainless hlau, los ntawm ib tug peev casting. Ua ntej, lub casting los ntawm lub foundry yuav tsum tau soj ntsuam. Tej zaum yuav tua blasting ceev los ntxuav nws. Tom qab ntawd, nws mus rau CNC tshuab dhos rau tig lub bore thiab lub ntsej muag rov qab - qhov no tsim cov thawj datum. Tom ntej no, nws tau tsiv mus rau 4 los yog 5-axis zeb. Ntawm no, cov hniav, lub hauv ntej shroud, thiab tej ports yog machined. Qhov no hnyav, cuam tshuam kev txiav, yog li cov cuab yeej ruaj ntseg yog qhov tseem ceeb.
Tom qab ntawd, tej zaum yuav muaj kev ntxhov siab rau cov kauj ruam yog tias lub machining tau nruj heev. Tom qab ntawd, rov qab mus rau lub tshuab dhos lossis lub tshuab sib tsoo kom tiav qhov tseem ceeb sealing nto thiab lub bore mus rau qhov kawg siab ntev. Thaum kawg, deburring, tu, thiab tej zaum ib tug passivation txheej txheem rau stainless hlau. Nyob rau hauv tas li ntawd, kev soj ntsuam yog interleaved - tom qab thawj op, tom qab roughing, tom qab ua tiav. Koj tsis tuaj yeem tshawb xyuas qhov zoo rau hauv ib feem ntawm qhov kawg.
Lub ntsiab lus yog, 'hom' ntawm precision machining yog cov theem no, txhua tus xaiv vim li cas. Nws yog qhov ntws. Lub khw uas tsuas yog milling yuav tsim ib feem, tab sis lub khw uas nkag siab txog tag nrho cov saw hlau, los ntawm txoj kev casting mus rau qhov kawg honing, zoo li kev ua haujlwm sib xyaw ua ke, tsim cov khoom siv txhim khu kev qha. Qhov kev ua tsis tiav uas kuv tau pom feem ntau yog los ntawm kev sib txuas hauv cov saw hlau no-tus machinist thawb cov khoom hnyav heev kom txuag tau lub sijhawm, ua rau lub subsurface rau cov kauj ruam tom ntej sib tsoo, lossis cov txheej txheem kho cua sov uas tsis suav rau hauv cov nyiaj siv ua haujlwm.
Thaum kawg, categorizing los ntawm hom tshuab yog pib. Tab sis kev txawj ntse muaj tseeb nyob rau hauv kev nkag siab tias cov txheej txheem no cuam tshuam li cas, cov ntaub ntawv hais txog lawv cov cai, thiab lub hauv paus-kev ua kom zoo-ua rau txhua qhov kev txiav txim tom ntej tsis yog ua tau, tab sis kev lag luam. Qhov ntawd yog qhov kev xav uas koj tau txais los ntawm kev nyob hauv khw, tsis yog nyeem phau ntawv teev npe xwb.
