Thaum cov kws tshaj lij qhia cov khoom siv rau cov twj hydraulic, cov dej tawm sab nraud, lossis cov tshuab ua haujlwm hnyav, lawv tsis yog xav tau "ze txaus." Lawv xav tau precision mechanical qhov chaw Hoobkas tso zis qhov twg ± 0.01 mm kam rau ua tsis yog ib qho ntxiv - nws yog lub hauv paus. Peb tau pom cov neeg siv khoom xa rov qab peb lub voj voog ntawm cov qauv vim tias qhov loj me me hauv cov cobalt alloy nozzles ua rau lub rooj zaum ntxov ntxov. Peb tau saib lub sij hawm xa khoom tawg thaum casting shrinkage tsis them nyiaj rau hauv CNC teeb. Tias yog vim li cas peb tsom mus rau qhov ua haujlwm tiag tiag - tsis yog daim ntawv qhia, tab sis lub ntiaj teb rov ua dua nyob rau hauv lub siab, cua sov, thiab lub voj voog.
Real-World Precision pib nrog kev tswj cov khoom-tsis yog Machining xwb
Cov khw feem ntau kho cov khoom raws li qhov pib. Peb kho nws raws li tus txheej txheem thawj kauj ruam. Cobalt-nickel alloys zoo li AMS 5387 thiab T800 tsis yog nyuaj rau tshuab-lawv yog metallurgically rhiab heev. Qhov sib txawv ntawm 5 ° C thaum lub sij hawm kev daws teeb meem annealing hloov pauv cov ciam teb carbide faib. Qhov ntawd hloov pauv kev hnav tsis kam hauv lub tog raj kheej lub tog raj kheej los ntawm 37%, raws li peb qhov kev ntsuas sab hauv coj mus txog 12,000 lub voj voog. Yog li peb koom tes nrog cov ntawv pov thawj daim ntawv pov thawj nrog cov neeg muag khoom uas muab tag nrho cov cua sov traceability-down rau lub cub tawg batch ID thiab txias tus nqi cav-tsis yog tsuas yog daim ntawv pov thawj zeb. Thaum ib tus neeg siv khoom xa tuaj rau peb kos duab rau qhov tsis yog-tus qauv cobalt alloy plug, peb tau teeb tsa lub hardness ntau yam tiv thaiv qhov tseeb tensile zog nkhaus rau qhov kub ntawd. Qhov tshwm sim? Kev kho cua sov hloov kho lub voj voog uas xa HRC 42-44 * thiab * khaws cov kev cuam tshuam toughness saum 28 J ntawm -20 ° C. Tsis muaj rework. Tsis ncua.
Vertical Integration tsis yog Buzzword-Nws yog li cas koj tuav kev zam dhau ntawm cov txheej txheem
Casting + machining + tiav hauv ib lub ru tsev hloov txhua yam. Xav txog lub tshuab hluav taws xob winch center ncej cov menyuam: xuab zeb-cam khwb cia hlau (ASTM A536 Qib), tom qab ntawd tiav-machined rau ± 0.008 hli ntawm cov ntaub ntawv xov xwm, ces induction-hardened rau 58-62 HRC. Yog tias cov kauj ruam no tshwm sim thoob plaws peb tus neeg muag khoom, thermal distortion los ntawm kev tshem tawm kev ntxhov siab tau raug kaw ua ntej machining pib - thiab koj caum geometry es tsis txhob tuav nws. Ntawm peb lub chaw Qingdao, peb tshuab tsis pub dhau 48 teev ntawm casting shakeout. Peb siv cov txheej txheem CMM kuaj tom qab roughing, semi-tiav, thiab tiav-txhua qhov khi rau GD&T callouts, tsis yog qhov nominal qhov ntev. Rau piston twj tso kua mis lub tog raj kheej vaj tse, peb txheeb xyuas bore cylindricity * ua ntej * zaum kawg honing, tsis yog tom qab. Qhov ntawd catches fixture-induced distortion thaum ntxov. Xyoo tas los, qhov no tau ntes tau 0.015 hli taper hloov hauv 17% ntawm thawj pawg thawj zaug - tiv thaiv 220 kg ntawm seem thiab rau lub lim tiam rov tsim dua.
Qhov Zoo Tsis Tshuaj Xyuas Hauv - Nws Ua Hauv, Ib kauj ruam los ntawm kauj ruam
Peb tsis ua "kev tshuaj ntsuam zaum kawg." Peb ua theem-gated pov thawj. Cov khoom siv raw tau txais kev soj ntsuam spectrographic * thiab * kuaj ultrasonic rau subsurface porosity-tshwj xeeb tshaj yog qhov tseem ceeb rau AMS 5387 twj tso kua mis qhov chaw raug pulsating high-pressure kua. Thaum lub sij hawm CNC, cov neeg ua haujlwm tau teev cov cuab yeej siv ib qho dhau los siv laser ntsuas qhov txiaj ntsig offset - tsis yog lub sijhawm kwv yees. Tom qab kev kho cua sov, txhua qhov ntau dhau los ntawm microhardness daim ntawv qhia hla peb ntu ntu. Qhov kawg tau txais kev sim ua haujlwm: lub siab li qub yog ntsuas-kuaj ntawm 1.5 × ntsuas siab; cobalt alloy nozzles dhau kev yaig simulation nrog 80-micron alumina slurry ntawm 30 m / s tshaj tawm. Thiab yog - peb khaws tag nrho cov ntaub ntawv. Tsis yog qhia xwb. Raw CMM cov ntaub ntawv, thermal imaging cav, hardness printouts. Traceability tsis yog hais txog kev ua raws cai. Nws yog hais txog kev paub * tseeb * yog vim li cas qhov #W-8823 tuav 0.005 hli roundness thaum #W-8824 drifted 0.012 hli - thiab kho nws ua ntej cua sov tom ntej.
Qhov no txhais li cas rau koj qhov project tom ntej
Yog tias koj daim ntawv thov xav tau kev zam nruj ntawm superalloys, complex contours, los yog lub hom phiaj tseem ceeb - tsis txhob pib nrog ib daim ntawv thov. Pib nrog kev tshuaj xyuas manufacturability. Xa koj pob GD&T. Peb yuav chij qhov twg cov kaum sab xis tsis sib haum xeeb nrog kev ua tau zoo, qhov uas cov phab ntsa nyias nyias muaj feem cuam tshuam rau hauv kev kho cua sov, los yog qhov chaw ua tiav qhov tshwj xeeb tshaj qhov ua tiav yam tsis muaj kev sib tsoo thib ob. Peb tau pab North American oilfield cov neeg muas zaub txiav lub sij hawm ua txhuas los ntawm 30% los ntawm kev hloov los ntawm peev-cam khwb cia-tsuas yog mus rau hybrid cam khwb cia-machined designs - tuav lub zog thaum tshem tawm tsib theem ob ua hauj lwm. Rau European hydraulics OEMs, peb tau tsim nyog T800 alloy Cheebtsam rau EN 10204 3.2 certification - tsis ntxiv tus nqi lossis sijhawm pheej hmoo. Precision mechanical qhov chaw Hoobkas muaj peev xwm tsis ntsuas nyob rau hauv spindle suav los yog pem teb chaw. Nws ntsuas nyob rau hauv pes tsawg qhov sib txawv koj tswj - thiab tsawg npaum li cas surprises ua rau nws los ua ke. Nov yog tus qauv peb tuav. Txhua lub sijhawm.
