Thaum engineers qhia a Machining Service Hoobkas rau lub hom phiaj tseem ceeb hydraulic li qub lossis cobalt-alloy twj tso kua mis, lawv tsis yog tsuas yog xaj hlau-lawv tab tom twv ntawm qhov ruaj khov nyob rau hauv 300 bar, microstructure kev ncaj ncees tom qab kev kho cua sov, thiab xoom batch-rau-batch drift hauv corrosion kuj. Tias yog vim li cas qhov tseeb tsis yog ib chav haujlwm ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.—nws yog qhov kev ua haujlwm.
Lub ntiaj teb tiag tiag pib qhov kev ua siab ntev nruj-thiab cov ntaub ntawv rov qab
Peb tau pom ntau zaus: tus neeg siv khoom xa GD&T-nplua nuj daim duab rau AMS 5387 cobalt alloy nozzle, cia siab tias ± 0.01 hli roundness ntawm 12 hli sab hauv. Standard CNC khw tsis kam nws. Lwm cov lus hais - ces ncua peb zaug thaum reprogramming toolpaths lossis regrinding inserts. Ntawm peb qhov chaw ua haujlwm ISO-raws li hauv Qingdao, qhov chaw nkoj hauv 14 hnub vim tias peb tshuab nws ntawm 5-axis kab rov tav nrog cov txheej txheem CMM pov thawj - tsis yog qhov chaw kuaj zaum kawg, tab sis raws li cov lus pom nyob rau lub sijhawm roughing. Tsis xav tsis thoob. Tsis muaj rework. Tsuas yog rov ua tau qhov tseeb ntawm cov alloys uas hnav cov cuab yeej carbide 3 × sai dua 304 stainless.
Qhov no tsis yog theoretical. Nws tau tsim rau hauv peb li cas T800-raws li cov khoom siv: ua ntej tshav kub kho kev ntxhov siab ua ntej kev ua haujlwm ntxhib, tom qab ntawd tuav cov duab kos los ntawm kev txiav tiav kawg ntawm kev tswj cov ntxaiv ceev thiab cov dej txias ntws. Peb tsis "hloov" rau cov ntaub ntawv nyuaj - peb ua haujlwm nyob ib puag ncig lawv cov thermal expansion coefficient, kev ua haujlwm hnyav, thiab tus cwj pwm tawg. Tias yog vim li cas piston twj tso kua mis lub tog raj kheej vaj tse rau offshore roj & roj cov neeg tau txais kev pab raws li API 6A Annex F yuav tsum tsis muaj kev sib tsoo thib ob.
Kev sib koom ua ke ntsug tsis yog lo lus buzz-nws yog koj qhov kev lees paub xa khoom
Qee tus neeg muag khoom outsource casting. Lwm tus outsource tiav. Ob peb txawm ua liaj ua teb tawm tshuaj xyuas. Qhov kev sib cais ua rau kev ua siab ntev ntawm cov khoom sib txawv, cov khoom siv traceability, thiab ntiv tes taw thaum lub siab valve tawm ntawm 250 ° C.
Ntawm QINGDAO QIANGSENYUAN, ib pab neeg muaj cov saw hlau tag nrho: peev casting ntawm cov hlau vaj tsev → CNC tig thiab milling ntawm sealing nto → nqus cua sov kho → tua peening → CMM-mapped nto tiav validation. Thaum lub winch center ncej cov menyuam xav tau HRC 58-62 nto hardness * thiab * Ra ≤ 0.4 µm ntawm bearing journals, peb tswj tus nqi quench * thiab * qhov kawg dhau qhov tob - tsis yog ob tus neeg muag khoom hla cov ntaub ntawv hla email.
Qhov no tshem tawm cov "black box" ntawm casting porosity thiab machined nto kev ncaj ncees. Peb tau lees paub cov ntaub ntawv pov thawj raw khoom los ntawm Tier-1 cov chaw muag khoom * ua ntej * nchuav - taug qab cov cua sov rau ib tus neeg castings, tom qab ntawd kos cov cua sov tib yam rau qhov kawg IDs. Yog tias tus neeg siv khoom nug txog kev taug qab tag nrho mus rau lub cav yaj, peb xa nws hauv PDF thiab Excel - tsis muaj kev hu xov tooj ntxiv.
Koj xav tau qhov chaw ua haujlwm - tsis yog qhov tseeb qhov tseeb xwb
"Nws haum rau daim duab" tsis txhais hais tias nws ua haujlwm. Peb tau tshuaj xyuas ntau pua lub twj tso kua mis lub hauv paus tsim qhov chaw ntsia liaj qhov rooj qhov chaw zoo tshaj plaws - tab sis lub mounting nto flatness tso cai rau 0.08 hli deflection nyob rau hauv torque, ua rau lub foob extrusion hauv kev pabcuam. Yog vim li cas peb qhov kev tshuaj xyuas engineering mus dhau GD&T kuaj xyuas.
Peb chij manufacturability pheej hmoo ntxov: nyias-walled cobalt alloy plugs nquag chatter-induced micro-cracks? Peb hais kom hloov kho toolpath ua ntu zus thiab paub meej nrog kev soj ntsuam kev vibration. Non-standard steel castings nrog cov cua txias sab hauv? Peb txheeb xyuas cov txheej txheem luam tawm ua ntej * ua ntej * pwm sib dhos - tsis yog tom qab thawj tsab ntawv tshuaj ntsuam tsis ua tiav.
Peb cov ntaub ntawv qhia txog qhov ua kom pom tseeb: lub siab li qub uas tswj lub rooj sib txig tom qab 50,000 lub voj voog; twj tso kua mis tsim engineered rau dynamic load faib; AMS 5387 twj tso kua mis validated tiv thaiv ASTM E112 grain loj thiab ASTM E1268 suav nrog cov qauv. Cov no tsis yog cov khoom catalog. Lawv yog cov kev daws teeb meem nyuaj los ntawm kev siv thaj chaw - tsis yog cov qauv kuaj.
Kev ntseeg tau txhais tau tias cov txiaj ntsig tau tshwm sim-tsis yog cov lus cog tseg xwb
Kev xa khoom tsis yog hais txog daim ntawv qhia hnub. Nws yog hais txog lub suab. Peb cov kev ua haujlwm lean siv takt lub sij hawm npaj-tsis yog Gantt kab kos-rau nruab nrab-ntim xaj. Prototype khiav tau mob siab rau lub sijhawm teem sijhawm; ntau lawm batches xauv hauv cov khoom faib ua ntej tso tawm. Thaum ib tug European OEM xav tau 120 cobalt-nickel nozzles rau ib tug qauv xeem rig - nrog tag nrho cov ntaub ntawv pov thawj thiab nto roughness qhia - peb xa nyob rau hauv 10 hnub ua hauj lwm. Tsis yog "kom sai li sai tau." Tsis yog "muaj peev xwm." Hnub 10.
Qhov kev sib raug zoo no yog los ntawm cov ntaub ntawv soj ntsuam cov txheej txheem - tsis yog cov ntawv txheeb xyuas uas tau theej los ntawm ISO 9001 cov qauv, tab sis cov txheej txheem sau los ntawm cov kws kho tshuab uas tau ntsuas 2,000 + T800 qhov chaw. Txhua qhov khoom cobalt alloy bar tau txais spectrographic pov thawj. Txhua lub twj tso kua mis ua tiav nyob rau hauv kev tshuaj ntsuam dye penetrant * thiab * hydrostatic siab tuav ntawm 1.5 × ua hauj lwm siab. Tsis muaj dab tsi hla dhau.
Yog tias koj tab tom nrhiav cov khoom siv hlau ua haujlwm siab uas tsis ua haujlwm txhais tau hais tias lub sijhawm poob qis, kev pheej hmoo ntawm kev nyab xeeb, lossis kev tswj hwm tsis ua raws cai - ces kev ntseeg siab tsis yog kev lag luam. Nws yog ntsuas tau repeatability. Nws yog cov khoom siv traceable. Nws yog kev tshaj lij machining pov thawj ntawm alloys uas thawb cov cuab yeej mus rau nws qhov txwv. Qhov ntawd yog tus qauv muaj tseeb Machining Service Hoobkas xa - tsis yog qee zaus, tab sis txhua lub sijhawm.
