Thaum cov neeg feem coob hnov 'precision ntsia hlau machining', lawv tam sim ntawd duab Swiss-type lathes churning tawm me me, complex qhov chaw. Qhov ntawd tsis yog qhov yuam kev, tab sis nws yog qhov pom ntawm qhov chaw. Qhov kev sib tw tiag tiag, qhov uas cais cov khw muag khoom, tsis yog hais txog kev tuav nruj nruj-nws yog hais txog kev tswj hwm tag nrho lub neej ntawm ib feem, los ntawm cov khoom siv coj mus rau kev ua haujlwm tom qab kev ntxhov siab, tshwj xeeb tshaj yog thaum koj tab tom cuam tshuam nrog cov khoom tawv zoo li nickel-based alloys. Kuv tau pom ntau tus qauv tsim los nyob rau hauv uas qhia meej tolerances nruj dua li qhov tsim nyog, tsav tus nqi tsis muaj txiaj ntsig zoo. Lub precision yog nyob rau hauv kev npaj, tsis yog txiav.
Cov khoom yog thawj daim ntawv qhia
Koj tsis tuaj yeem tham txog kev ua haujlwm precision yam tsis tau pib nrog cov Tshuag. Qhov no yog qhov uas ntau qhov kev xav tsis tiav. Ib lub tuam txhab zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nrog lawv peb xyoo caum hauv casting thiab machining, tau txais qhov no instinctively. Lawv tsis tsuas yog tau txais daim ntawv nyiaj xwb; lawv feem ntau pib nrog lawv tus kheej castings. Lub homogeneity, kev ntxhov siab nyob rau hauv lub xeev los ntawm lub plhaub pwm los yog peev casting txheej txheem - uas teev cov theem rau txhua yam uas los tom qab. Yog tias cov khoom siv hauv paus muaj qhov tsis sib xws, koj cov txheej txheem machining tsuas yog sau lawv, tsis tsim kom muaj qhov tseeb.
Ua hauj lwm nrog tshwj xeeb alloys, hais rau ib tug high-kub aerospace fastener, hloov qhov kev ua si kiag li. Cobalt-raws li alloys ua hauj lwm-harden sai heev. Koj lub cuab yeej txoj kev, pub, thiab nrawm dhau los ua kev sib tham nrog cov khoom, tsis yog lus txib. Ib qhov kev pab cuam precision uas tsis suav rau qhov no yuav tsim qhov zoo nkauj zoo nkauj uas yog tag nrho ntawm micro-cracks lossis muaj cov txheej txheem ua haujlwm tawv tawv uas yuav ua tsis tiav hauv kev pabcuam. Kev kam rau ntawm daim ntawv luam tawm yuav yog ± 0.0005, tab sis qhov tseeb spec yog kev ncaj ncees ntawm cov qauv nplej.
Kuv nco qab txog qhov project rau cov kua dej tswj valve qia. Cov ntawv luam tau hu rau 316 stainless, tab sis daim ntawv thov cuam tshuam nrog kev ntxhov siab. Peb pom zoo kom hloov mus rau lub tshuab nqus tsev-melted variant nrog kev tswj nruj dua ntawm kev suav nrog. Tus nqi ib qho dawb tau nce mus, tab sis qhov txo qis hauv cov cuab yeej hnav thiab tshem tawm cov kev ua tsis tiav thaum lub sijhawm kuaj pov thawj tau txais txiaj ntsig ntau dua. Cov precision ntsia hlau machining tau zoo ib yam ntawm daim ntawv, tab sis qhov tshwm sim txawv vim tias cov khoom raug kho raws li qhov sib txawv, tsis tas li.
Qhov twg Casting ntsib Machining: Qhov tseem ceeb Handoff
Qhov no yog cov kua ntses zais cia rau kev ua haujlwm vertically integrated. Ntawm qhov chaw uas ua ob qho tib si, zoo li QSY, pab pawg machining tsis ua haujlwm tawm tsam qhov tsis qhia npe. Lawv muaj keeb kwm nrog nws. Lawv paub txog qhov kev siv nyiaj shrinkage, qhov chaw ntawm lub rooj vag, lub peev xwm rau me ntsis porosity zones hauv qee qhov geometries. Qhov no tsis tau sau tseg rau txhua tus neeg taug kev; nws yog haiv neeg kev paub.
Rau ib tug complex peev-casted vaj tse uas xav tau meej threaded ports, machinist paub uas datums yog feem ntau txhim khu kev qha los ntawm lub casting. Tej zaum lawv yuav tawm ib nrab ib millimeter ntxiv rau ntawm phab ntsa tshwj xeeb, tsis yog vim tias cov ntawv luam yuav tsum tau, tab sis vim lawv paub tias cov phab ntsa hauv cov hlau no feem ntau cuam tshuam tsawg heev thaum kho cua sov, thiab lawv yuav ntaus qhov kawg spec tom qab cov kauj ruam ntawd. Qhov no yog precision ntsia hlau machining xav nyob rau hauv plaub qhov ntev, ntxiv lub sij hawm thiab cov txheej txheem ua ntu zus rau hauv pawg kam rau ua.
Hom kev ua tsis tiav uas kuv tau pom yog thaum machining yog siloed. Lawv tau txais ib qho casting, clamp nws, thiab pib txiav. Yog hais tias lub casting muaj ib tug me ntsis hneev los ntawm residual kev nyuaj siab, lawv yuav tshuab nws ncaj ... tsuas yog kom nws nkag tau rov qab tom qab lub clamps raug tso tawm. Qhov tam sim no seem, tab sis nws ntsuas zoo kawg nkaus ntawm CMM thaum kho. Kev koom ua ke tiv thaiv qhov no. Lub phiaj xwm machining yog ib feem ntawm kev tshuaj xyuas kev tsim qauv.
Tooling Philosophy: Tsis yog Hais Txog Cov Cuab Yeej
Tham nrog ib tus kws kho tshuab, thiab lawv yuav geek tawm ntawm cov cuab yeej geometry thiab txheej txheej. Qhov ntawd tseem ceeb heev. Tab sis lub tswv yim tom qab tooling lub tswv yim yog dab tsi txhais lub khw lub peev xwm. Rau high-precision, me-batch ua hauj lwm ntawm alloys, nws yog hais txog kev kwv yees, tsis yog lub ncov kev ua tau zoo.
Peb standardized ntawm ib lub npe tshwj xeeb ntawm micro-grain carbide inserts rau kev ua tiav ops ntawm steel alloys. Tsis yog vim tias lawv yog qhov nyuaj tshaj plaws, tab sis vim tias lawv qhov nkhaus hnav yog linear thiab kwv yees. Peb tuaj yeem khiav ib puas ntu, ntsuas cov cuab yeej hnav, thiab ntseeg tau tias yuav tsum tau hloov pauv cov khoom ua ntej kev ua siab ntev drift. Qhov no yog boring, unsexy precision. Nws tsis yeej qhov khoom plig ceev, tab sis nws tshem tawm cov khoom seem. Koj tuaj yeem pom qhov no pragmatic txoj hauv kev tau piav qhia hauv cov kev pabcuam hauv lub vev xaib xws li tsi.com, qhov chaw tsom mus rau cov txheej txheem kev ntseeg siab rau cov khoom tseem ceeb.
Coolant tsis yog ib lub roj nplua nyeem xwb; nws yog ib tug thermal tswj system. Thaum koj tuav feem kaum ntawm lub taub hau stainless, lub tshav kub ntawm kev txiav yuav tsum tau rub tawm tsis tu ncua. Ib qho 5-degree Celsius viav vias nyob rau hauv ib feem ntawm qhov kub tuaj yeem ua rau koj lub siab ntev. Peb muaj ib txoj hauj lwm qhov chaw ntsuas hauv-spec ntawm lub tshuab tab sis ua tsis tiav QA zaum kawg. Qhov teeb meem? CMM chav tsev yog 10 degrees txias dua. Cov khoom tau cog lus. Qhov tseeb tau ploj mus rau qhov yooj yim physics. Tam sim no, thermal equilibrium yog ib feem ntawm peb thawj tsab ntawv txheeb xyuas.
Lub Fixturing Fallacy
Txhua tus paub tias kev kho kom zoo yog qhov tseem ceeb. Lub fallacy yog xav complex, kev cai fixtures yeej ib txwm teb. Rau qhov tseeb precision ntsia hlau machining, tshwj xeeb tshaj yog nyob rau hauv legacy multi-spindle automatics los yog Swiss lathes, tej zaum qhov zoo tshaj plaws kev daws teeb meem yog ib tug hloov qauv collet los yog ua tib zoo muab tso rau nyob rau hauv lub center.
Kuv kawm qhov nyuaj no. Tsim kom muaj ib qho zoo nkauj, zoo siab fixture rau tsev neeg ntawm tooj dag connector qhov chaw. Nws tuav rau ntawm ib lub sij hawm, machined tag nrho cov nta hauv ib qho op. Hauv kev xav, zoo tag nrho. Nyob rau hauv kev xyaum, tej me me nti embedded nyob rau hauv lub fixture lub cev yuav qaij ib feem fractionally, scrapping tag nrho batch. Peb siv sijhawm ntau dua los ntxuav thiab txheeb xyuas cov khoom siv ntau dua li cov khoom siv khiav. Rov qab mus rau qhov yooj yim, ib feem ntawm kev ua haujlwm collet. Lub sij hawm voj voog ib feem yog ntev dua, tab sis tag nrho cov khoom siv thiab cov txiaj ntsig tau nce siab. Precision yog feem ntau hais txog kev txo qhov sib txawv, tsis ntxiv qhov nyuaj.
Rau ntev, nyias cov ntsia hlau-xav tias cov ntsia hlau lead lossis actuator shafts-cov khoom siv yog tag nrho cov txheej txheem. Koj tawm tsam deflection. Txoj kev ua kom yuam kev tsis yog ib txwm nyob ruaj khov. Qee lub sij hawm nws yog ib ntus ntawm kev ua haujlwm: tig, kev ntxhov siab, thiab ua tiav tig. Koj tshuab qhov thib ob zaug kom nws pom nws lub xeev ntuj nyob nruab nrab. Lub sijhawm tshuab ob npaug, tab sis qhov ua haujlwm. Qhov ntawd yog kev txheeb xyuas cov txiaj ntsig uas koj yuav tsis pom hauv phau ntawv.
Kev ntsuas yog txheej txheem, tsis yog kauj ruam
Kev tshuaj xyuas zaum kawg tsis yog kev tswj xyuas zoo; nws yog kev soj ntsuam. Qhov zoo tiag tiag yog tsim rau hauv cov txheej txheem. Rau cov ntsia hlau machining, qhov no txhais tau hais tias hauv kev ntsuas ntsuas, SPC cov ntaub ntawv sau rau ntawm qhov loj me, thiab - qhov tseem ceeb - nkag siab qhov koj ntsuas.
Ib tug threaded kho mob implant tivthaiv tej zaum yuav muaj ib tug zoo meej txoj kab uas hla thiab suab. Tab sis yog tias lub hauv paus xov muaj lub vojvoog me me los ntawm cov cuab yeej hnav, nws dhau los ua kev ntxhov siab. Ib tug qauv xov plug gauge yuav dhau nws. Ib tug optical piv los yog ib tug profileometer yuav ntes nws. Lub ntsiab txhais ntawm precision rau ib feem muaj xws li nto tiav spec nyob rau hauv lub hauv paus. Koj yuav tsum ntsuas qhov yog.
Peb ua ke ib qho yooj yim laser micrometer ntawm cov khoom noj khoom haus rau ib txoj hauj lwm siab pin. Nws tsis yog rau sorting; nws yog rau kev soj ntsuam. Pom txoj kab uas hla ntawm cov khoom lag luam tawm los ntawm ob peb microns tso cai rau peb los kho cov cuab yeej offsets ua ntej cov khoom tawm ntawm spec. Qhov no yog qhov kev xav: kev ntsuas raws li lub voj voog tawm tswv yim rau lub tshuab, tsis yog lub rooj vag dhau / poob ntawm qhov kawg. Nws ua raws li kev qhia dav dav uas koj pom los ntawm cov neeg tsim khoom tsim uas tswj cov saw hlau tag nrho, los ntawm kev xaiv alloy mus txog qhov kawg metrology.
Nqa tag nrho rov qab rau hauv pem teb
Yog li qhov no tso peb nyob qhov twg? Precision ntsia hlau machining tsis yog department; nws yog kab lis kev cai. Nws yog tus neeg siv khoom tham nrog pab pawg casting, uas tham nrog tus programmer, uas mloog tus kws kho tshuab ua haujlwm, uas pub cov ntaub ntawv rov qab mus rau tus kws ua haujlwm zoo. Nws yog hais txog kev txiav txim siab nrog rau tag nrho cov txheej txheem hauv siab.
Thaum koj saib lub tuam txhab muaj peev xwm, zoo li cov uas tau teev tseg rau QSY, qhov tseem ceeb tsis yog cov npe ntawm cov tshuab. Nws yog qhov tseeb tias lawv tau ua casting thiab machining nyob rau hauv ib lub ru tsev rau ntau tshaj 30 xyoo. Qhov kev ncua ntev qhia tias lawv tau daws cov teeb meem kev koom ua ke no. Lawv yuav tau kawm, los ntawm kev sim thiab ua yuam kev, yuav ua li cas tshuab ib tug casting tsis shocking nws, yuav ua li cas xaiv ib tug alloy uas yuav tshuab huv si thiab ua nyob rau hauv lub teb, thiab thaum lub sij hawm ib tug ± 0.001 kam rau ua yog zoo txaus.
Qhov kev xeem zaum kawg yog ib feem ntawm daim ntawv thov. Kuv twb pom exquisitely machined screws poob vim hais tias cov precision tsuas yog tawv-dav. Thiab kuv tau pom qhov chaw nrog ob peb qhov chaw ntxhib ntawm qhov chaw tsis tseem ceeb ua tau zoo rau ntau xyoo lawm vim tias cov yam ntxwv tseem ceeb tau ua nrog kev nkag siab tob txog cov khoom siv, txheej txheem, thiab kev ua haujlwm. Qhov ntawd yog lub hom phiaj tiag tiag. Nws yog ntxhov, rov hais dua, thiab tag nrho ntawm kev txiav txim hu. Thiab qhov ntawd yog qhov ua rau nws yog khoom siv tes ua tiag tiag, tsis yog ib txoj kab ntawm daim ntawv muaj peev xwm.
