Thaum koj hnov 'siab precision machining', thawj yam uas tshwm sim rau ntau tus neeg lub taub hau yog tus lej. Peb tuaj yeem tuav qhov ntev rau ± 0.001 ntiv tes lossis Peb cov tshuab muaj peev xwm ua tau raws li qhov tseeb ntawm cov micron. Qhov ntawd yog daim ntawv qhia ci ntsa iab tham. Zaj dab neeg tiag tiag, qhov tseem ceeb ntawm lub khw hauv pem teb, pib tom qab koj tau yuav lub lab-duas tsib-axis CNC machining chaw. Qhov ntawd yog thaum koj kawm precision tsis yog hais txog lub tshuab spec ntawv; nws yog saw hlau. Cov saw hlau ntawm kev tswj qhov kub thiab txias, cov cuab yeej hnav, kev sib tw rigidity, cov khoom siv coj los siv, thiab, ncaj ncees, tus neeg teb xov tooj intuition. Ntau lub khw, tshwj xeeb tshaj yog cov dhia ntawm qhov dav mus rau 'siab-precision' ua haujlwm, nco qhov ntawd. Lawv xav tias lub tshuab ua txhua yam haujlwm. Qhov ntawd yog kev khiav ceev mus rau cov khoom kim heev.
Lub Foundation: Nws tsis yog CNC xwb
Kuv twb pom ntau zaus lawm. Lub khw tau txais qhov tshiab, high-end machining chaw, slaps ib qho thaiv ntawm 304 stainless ntawm lub rooj, thiab cia siab tias daim iav tiav thiab zoo meej bores. Tom qab ntawd lawv hu txog cov teeb meem kev vibration lossis thermal drift. Thawj lo lus nug uas kuv nug tam sim no tsis yog hais txog lawv cov pub thiab ceev; nws yog hais txog lawv lub hauv paus. Lus. Puas yog hauv pem teb monolithic slab cais los ntawm lwm cov nroj tsuag tsheb? Rau theem ntawm kev ua haujlwm peb ua ntawm peb qhov chaw, zoo li cov geometries complex rau valve Cheebtsam los ntawm tshwj xeeb alloys, txawm lub forklift tsav los ntawm 50 ko taw deb yuav qhia tau ib tug tshee uas tshwm sim raws li ib tug 0.0002 chatter cim. Koj ua tsis tau qhov program ntawd tawm.
Ces muaj huab cua. Khiav a high precision machining cell zoo li khiav lub ntsuas ntsuas ntsuas. Peb tuav ib puag ncig tswj, ± 2 ° F yog tias peb tuaj yeem pab tau. Aluminium thiab hlau nthuav dav thiab cog lus ntau dua li qhov koj xav tau hauv ib hnub. Yog tias koj pib ua haujlwm thaum sawv ntxov thaum nws yog 68 ° F thiab ua tiav qhov tseem ceeb thaum tav su thaum nws yog 74 ° F ze ntawm lub qhov rais, koj tau poob koj qhov tseeb. Rau peb cov peev casting prototypes uas xav tau qhov kawg machining, qhov no yog tsis-negotiable. Ib feem tau dhau los ntawm kev siv quav ciab, plhaub, thiab ncuav txheej txheem; screwing nws nyob rau hauv lub kawg CNC theem vim yog kub yog lub plab punch.
Thiab tooling. Qhov no yog qhov uas xav tau los hauv. Koj tuaj yeem muaj qhov zoo tshaj plaws Swiss-made spindle, tab sis yog tias koj siv lub tshuab kawg zeb los ntawm ntau lub thawv, tsis nco qab nws. Peb muab cov cuab yeej tshwj xeeb, coated rau cov khoom sib txawv. Machining nickel-based alloy zoo li Inconel yog cov tsiaj nyaum sib txawv piv rau cov hlau. Cov cuab yeej geometry, txheej txheej (AlTiN vs. TiAlN), lub tshuab raj suav-nws yog qhov tseem ceeb rau kev tshem tawm cov cua sov thiab nti tawm. Cov cuab yeej hnav tsis yog tsuas yog ua kom tiav qhov tsis zoo; nws siv ntau dua kub thiab siab, warping qhov microscopically. Tej zaum koj tseem yuav ua siab ntev, tab sis qhov kev ntxhov siab seem yuav tom koj tom qab thaum lub rooj sib txoos. Peb kawm qhov no txoj kev nyuaj ntawm ib pawg ntawm cobalt-chrome kho mob implant fixtures.
Material Memory thiab Machining Dance
Qhov no yog ib tug nuance uas cais ib feem-makers los ntawm precision engineers. Cov ntaub ntawv muaj kev nco. Castings, peb qhob cij thiab butter ntawm Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), yog cov piv txwv tseem ceeb. Lub plhaub pwm casting lossis peev casting tuaj rau hauv CNC department nrog qhov tseeb, kaw-hauv kev ntxhov siab los ntawm cov txheej txheem txias. Yog tias koj cia li clamp nws thiab pib hogging tawm cov khoom aggressively, koj tab tom tso qhov kev ntxhov siab tsis sib npaug. Ib feem yuav txav mus, qee zaum ua rau, txoj cai ntawm lub rooj.
Cov txheej txheem peb tau tsim, tom qab ob peb qhov ua tsis tau tiav thaum ntxov, yog kev seev cev ntawm lub teeb hla thiab kev sib tw zoo sib xws. Peb tuaj yeem muab cov casting, ua qhov roughing op kom tau nyob rau hauv 0.050, ces unclamp nws, stress-relieve nws nyob rau hauv lub qhov cub, thiab ces rov kho nws rau semi-tiav. Tsuas yog tom qab ntawd peb mus rau qhov kawg, high precision machining hla. Nws ntxiv cov kauj ruam, nws ntxiv sijhawm, tab sis nws yog tib txoj kev los lav kev ruaj ntseg. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov phab ntsa nyias nyias uas muaj nyob hauv cov khoom siv dav hlau peb qee zaum ua. Qhov yuam kev classic yog mus caum kev ua tiav hauv ib qho kev teeb tsa; Qee zaum, koj yuav tsum cia qhov chaw nyob ntawm qhov kev ua.
Fixturing yog nws daim duab kos duab. Rau ib qho nyuaj, asymmetrical peev-cam khwb cia ib feem, tsim lub fixture uas muab kev txhawb nqa nruj yam tsis muaj kev cuam tshuam clamping distortion yog ib qho kev sib tw. Peb feem ntau siv modular fixture systems thiab mos lub puab tsaig machined in-situ-lub ntsiab lus peb tshuab lub puab tsaig profiles ntawm tib lub tshuab uas yuav ua ib feem, guaranteeing zoo meej conformity. Nws yog lub sijhawm nqis peev ua ntej uas them tawm thoob plaws tag nrho cov kev tsim khoom. Kuv nco qab txog ib qhov project rau marine twj tso kua mis vaj tse nyob rau hauv duplex stainless hlau qhov twg thawj fixture tsim tshwm sim ib tug 0.0015 hneev. Nws tsuas yog pom ntawm CMM tom qab qhov tseeb. Peb redesigned los txhawb lub internal webbing thaum lub sij hawm machining, uas daws nws. Daim ntawv qhia tsis tau hais txog qhov ntawd; kev ua tau.
Metrology Feedback Loop
Koj tswj tsis tau qhov koj ntsuas tsis tau, tab sis koj kuj tsis tuaj yeem cia kev ntsuas ua rau koj tuag tes tuag taw. Lub hom phiaj tsis yog ntsuas txhua qhov tshwj xeeb ntawm txhua ntu - qhov ntawd tsis ruaj khov. Lub hom phiaj yog los tsim kom muaj kev txhawb nqa kev ntseeg siab ntawm lub tshuab thiab cov cuab yeej ntsuas. Peb CMM thiab laser scanners tsis yog rau kev soj ntsuam zaum kawg nkaus xwb; lawv yog cov txheej txheem kev txhim kho cov cuab yeej.
Thaum peb tau txais ib feem tshiab tsev neeg, hais ib tug tshiab series ntawm stainless hlau valve lub cev rau ib tug neeg, peb mam li khiav ib tug thawj-txoj kev txheej txheem uas yog hnyav instrumented. Tshuab tsib ntu. Tom qab txhua qhov haujlwm loj, ntsuas lawv. Tsis yog tsuas yog qhov tseem ceeb, tab sis kuj nrhiav cov qauv-yog txhua qhov chaw nyob hauv Z-axis los ntawm qhov sib npaug? Puas muaj lub taper nyob rau hauv ib lub bore uas qhia cov cuab yeej deflection? Cov ntaub ntawv ntawd rov qab mus rau CNC programmer. Peb tuaj yeem kho lub cuab yeej offset, hloov qhov kev txiav txim ntawm kev ua haujlwm, lossis ntxiv lub caij nplooj ntoos hlav hla. Lub voj no hloov lub tshuab los ntawm qhov muag tsis pom kev ua haujlwm rau hauv kev kawm. Cov CNC machining txheej txheem yuav ruaj khov thiab kwv yees.
Tab sis muaj qhov ntxiab ntawm no: dhau kev cia siab rau cov ntawv nyeem digital. Qee zaum, kev xav tseem ceeb. Ib tus kws paub txog kev siv tshuab ua tiav tiav ntawm titanium alloy tuaj yeem hnov qhov sib txawv ntawm kev txiav du thiab ib qho uas pib sib tham. Nws tuaj yeem pom cov xim nti thiab daim ntawv. Tias tactile tawm tswv yim yog tam sim ntawd. Tos CMM tshaj tawm ob teev tom qab ntawd lig dhau lawm. Yog li peb sib npaug. Tus neeg teb xov tooj lub tshuab muaj cov txheej txheem ntsuas micrometers thiab bore gages ntawm nws qhov chaw nres tsheb rau kev kuaj xyuas ntawm qhov tseem ceeb. Nws yog qhov sib xyaw ntawm digital precision thiab analog intuition uas ua kom zoo siab thiab seem qis.
Thaum Precision ntsib Cov Txheej Txheem Cai
Peb lub tuam txhab keeb kwm, tshaj 30 xyoo hauv kev tsim thiab tshuab, nthuav tawm qhov kev sib tw tshwj xeeb thiab kom zoo dua. Qhov kev sib tw yog kev koom ua ke niaj hnub high precision machining kev cia siab nrog cov txheej txheem tsim khoom qub. Kev nqis peev casting tej zaum yuav zoo nkauj, tab sis nws qhov chaw datum tej zaum yuav tsis haum rau CNC nqus chuck. Peb yuav tsum tau ua haujlwm rov qab qee zaum, koom tes nrog peb tus kheej cov neeg tsim khoom los hloov kho cov qauv tsim me ntsis-ntxiv cov cuab yeej me me, ua kom lub ntsej muag kom txaus rau clamping-kom nws tuaj yeem ua tau raws li niaj hnub zam. Nws yog kev sib tham sab hauv ntawm kev kos duab ntawm casting thiab kev tshawb fawb ntawm machining.
Qhov zoo dua, txawm li cas los xij, yog cov ntaub ntawv muaj txiaj ntsig zoo. Thaum tus neeg siv khoom xa peb daim duab kos rau ib feem hauv Monel lossis Hastelloy, peb tsis yog nyeem cov ntaub ntawv spec. Peb lub tuam txhab tau nchuav cov hlau tshwj xeeb no rau ntau xyoo lawm. Peb paub tias lawv coj li cas thaum lub sij hawm solidification, qhov twg porosity yuav nkaum, yuav ua li cas lawv hnov mob. Qhov no qhia peb lub tswv yim machining tam sim ntawd. Peb paub Hastelloy ua haujlwm nyuaj zoo li vwm, yog li peb yuav npaj rau cov cuab yeej ntse, kev koom tes tas li, thiab tsis txhob cia lub cuab yeej rub. Qhov kev pom zoo li ntawd tsis yog nyob rau hauv phau ntawv machining txheem; nws yog institutional memory. Nws tso cai rau peb hais thiab ua tiav ntawm txoj haujlwm nyuaj uas lub khw siv tshuab ntshiab yuav txaj muag ntawm.
Qhov kev sib koom ua ke no yog qhov peb siv zog ntawm QSY. Tus neeg siv khoom tuaj yeem tuaj nrog lub tswv yim, thiab peb tuaj yeem coj nws los ntawm kev xaiv cov khoom siv (los ntawm cov hlau cam khwb cia rau nickel-based alloys), rau hauv cov txheej txheem casting tsim nyog (plhaub pwm rau kev khiav loj, peev rau cov duab nyuaj), thiab thaum kawg los ntawm ib qho CNC machining txheej txheem tsim rau cov khoom tshwj xeeb thiab geometry. Lub precision tsis yog tom qab; nws tau tsim los rau hauv cov saw hlau tsim los ntawm qhov pib. Qhov ntawd yog lub ntsiab lus tiag tiag ntawm high precision machining nyob rau hauv cov ntsiab lus ntawm kev tsim khoom. Nws tsis yog chav haujlwm; nws yog ib lub tswv yim uas khiav ntawm qhov pib pwm mus rau qhov kawg deburring.
Tus nqi tiag tiag ntawm High Precision
Thaum kawg, qhov tseeb tsis tseeb. High precision yog kim, thiab nws yuav tsum yog. Nws yog kim nyob rau hauv peev (tshuab, kev tswj huab cua, metrology), nyob rau hauv consumables (tshwj xeeb tooling, high-zoo coolant), thiab feem ntau ntawm tag nrho cov, nyob rau hauv lub sij hawm thiab kev txawj ntse. Lub sij hawm voj voog rau ib feem precision yog ib txwm ntev dua. Muaj kev teeb tsa ntau dua, kev kuaj xyuas ntau dua, qeeb qeeb qeeb thiab nrawm kom tswj tau qhov chaw ruaj khov thiab qhov ntev.
Peb tau txais kev nug txhua lub sijhawm uas tus neeg yuav khoom xav tau aerospace-qib tolerances ntawm cov khoom muag. Nws yog kev tsis sib haum xeeb. Peb lub vev xaib, tsingtaocnc.com, nteg tawm peb lub peev xwm kom meej, tab sis kev sib tham hauv qab no yog hais txog kev kawm. Peb piav qhia vim li cas tuav 0.0002 txoj haujlwm tseeb ntawm peb qhov kev sib tshuam bores hauv 17-4 PH stainless hlau casting xav tau cov kauj ruam tshwj xeeb thiab, yog li ntawd, cov nqi tshwj xeeb. Qee lub sij hawm, peb txawm qhia tus neeg siv khoom kom ua siab ntev yog tias nws tsis ua haujlwm tseem ceeb - nws tuaj yeem txuag tau 30% ntawm tus nqi. Ua ib tus khub txhais tau tias qee zaum qhia lawv yam lawv tsis xav tau, uas ua rau muaj kev ntseeg ntau dua li kev cog lus rau qhov ua tsis tau.
Thaum kawg, high precision machining yog kev cog lus. Nws yog kev cog lus rau kev tswj hwm qhov sib txawv ntawm txhua tus neeg tsis quav ntsej, nqis peev hauv kev paub ntau npaum li hauv cov khoom siv kho vajtse, thiab nkag siab tias tus lej zoo meej ntawm lub vijtsam yog qhov tshwm sim ntawm ib puas yam tsis zoo, tib neeg kev txiav txim siab tau ua hauv khw hauv pem teb. Nws ntxhov siab, rov ua dua, thiab txaus siab heev thaum nws tag nrho los ua ke. Qhov ntawd yog qhov koj them nyiaj tiag tiag.
