Thaum engineers qhia precision casting qhov chaw chaw tsim tshuaj paus Hoobkas Hauv cov ntaub ntawv kev yuav khoom, lawv tsis yog xaj hlau xwb-lawv xav tau qhov ntev ntawm qhov rov ua dua hauv qab 0.02 hli, microstructure sib xws nyob rau hauv cov khoom siv kho cua sov, thiab kev ntseeg tau ua haujlwm tom qab 10,000 teev hauv hydraulic valve manifolds lossis offshore twj tso kua mis. Peb tau pom ntau txoj haujlwm kaw vim tias tus neeg muag khoom tau kho cobalt-nickel alloy casting li "tsuas yog lwm txoj haujlwm hlau." Tsis yog.
Vim li cas cov khoom coj tus cwj pwm dictates txheej txheem tsim-tsis yog lwm txoj kev nyob ib ncig ntawm
Cobalt-raws li alloys xws li AMS 5387 lossis T800 tsis tshuab zoo li stainless hlau. Lawv ua hauj lwm-hardening npaum li cas spikes tom qab 0.1 hli ntawm txiav qhov tob. Lawv cov thermal conductivity yog ib nrab ntawm 304 stainless - yog li cov cuab yeej lub neej poob 60% yog tias coolant siab poob qis dua 70 bar. Hauv peb lub khw, peb tsis pib nrog CNC program. Peb pib nrog cov ntaub ntawv metallurgical: grain loj faib los ntawm cov foundry, carbide nag lossis daus maps tom qab kev daws teeb meem annealing, thiab tensile nkhaus ntawm ob chav thiab 400 ° C. Tsuas yog tom qab ntawd peb kaw hauv spindle ceev, pub ib tus hniav, thiab stepover.
Qhov kev qhuab qhia no cais qhov tseeb precision casting peev xwm los ntawm qhov chaw-theem quoting. Ib lub twj tso kua mis North American OEM xa tuaj rau peb kos duab rau lub piston twj tso kua mis lub tog raj kheej vaj tse - nruj GD&T ntawm concentricity (Ø0.015 hli), qhov tseem ceeb sealing nto hauv av rau Ra 0.4 µm, thiab hardness yuav tsum tau ntawm 38-42 HRC tom qab laus. Lawv cov neeg muag khoom ua ntej siv cov xuab zeb casting + tiav machining. Qhov tshwm sim? 37% seem tus nqi vim subsurface porosity nyob ze ntawm lub siab bore. Peb hloov mus rau peev casting nrog lub tshuab nqus tsev-pab pouring, ntxiv ultrasonic kuaj ua ntej machining, thiab kev ntxhov siab-relief ntawm ntxhib thiab tiav txiav. Yield dhia mus rau 94%. Ib feem dhau qhov kev sim hydrostatic ntawm 1.5 × rated siab-tsis muaj qhov xau, tsis muaj kev cuam tshuam.
Plaub Yam Khoom—Txhua Ua rau Kev Ua Haujlwm Tsis Ua Haujlwm
Peb tsom tsuas yog rau cov khoom uas tsis ua haujlwm ua haujlwm lossis kev nyab xeeb. Tsis muaj hniav castings. Tsis tshua muaj siab ntev brackets. Tsuas yog lub hom phiaj tseem ceeb hlau:
- CNC machined qhov chaw: Multi-axis contouring ntawm hardened cobalt plugs thiab nozzles, nrog nyob rau hauv-txoj kev soj ntsuam xyuas cov phab ntsa thickness nyob rau hauv ± 0.05 hli ntawm 2-mm-thin seem
- Cobalt-nickel alloy Cheebtsam: AMS 5387 twj tso kua mis fabricated los ntawm ntawv pov thawj T800 billet, nrog tag nrho batch traceability rov qab rau yaj cav thiab ESR remelt daim ntawv pov thawj
- Hlau castingsASTM A48 Chav Kawm 35 grey hlau twj tso kua mis-tsim rau kev vibration damping, tsis yog load zoo li qub
- Hlau & stainless hlau castingsAISI 4140 thiab 17-4PH vaj tse rau engineering tsheb winch chaw ncej ncej chais, cua sov kho kom haum rau lub cev qaug zog specs
Txhua yam khoom xa tuaj nrog daim ntawv qhia txog cov khoom siv (MTR), daim ntawv soj ntsuam qhov loj me uas tau kos npe los ntawm CMM-tsim tus neeg teb xov tooj, thiab cov ntawv tsis pom kev pom nrog ISO 13919-1 weld txais cov qauv - txawm tias tsis muaj vuam tshwm sim. Vim li cas? Vim tias cov neeg siv khoom qhia peb lawv cov neeg soj ntsuam tam sim no xav tau nws rau Tier 1 oilfield cov chaw muag khoom.
Qhov Zoo Tsis Tshuaj Ntsuam Xyuas Hauv - Nws yog Engineered Hauv, Ib kauj ruam los ntawm kauj ruam
Qee lub tuam txhab ua haujlwm tshawb xyuas zaum kawg ntawm cov khoom tiav. Peb tshuaj xyuas ntawm tsib lub chaw kuaj xyuas tsis sib tham:
- Cov ntaub ntawv raw khoom pov thawj: Spectrometric tsom xam + ultrasonic bulk kuaj ntawm txhua kauj / daim ntawv ua ntej txiav
- Raws li-cam khwb cia geometry: Optical contour scanner xyuas cov kaum sab xis thiab cov tub ntxhais hloov ua ntej kev kho cua sov
- Tom qab tshav kub-kho hardness daim ntawv qhia: 9-point Rockwell C daim phiaj ntawm thaj chaw tseem ceeb, tsis yog ib qho chaw xwb
- Nyob rau hauv-txheej txheem CMM: Tom qab roughing, ua ntej tiav, kom paub meej tias cov nyiaj tso cai nyob twj ywm uniform
- Kev ua haujlwm tau zoo: Kev ntsuas siab li qub ntawm 1.3 × ua haujlwm siab; winch shafts spin-balanced rau G2.5 rau ISO 1940-1
Peb khaws cov ntaub ntawv digital rau 10 xyoo - tsis yog vim cov cai xav tau, tab sis vim tias ib tus neeg siv khoom ib zaug taug qab kev ua haujlwm tsis ua haujlwm rau ib pawg ntawm 2019 cobalt plugs. Peb cov txheej txheem traceability cia lawv cais thiab hloov tsuas yog 147 units - tsis yog 5,000.
Kev ntseeg tau pib nrog koj tham li cas—Ua ntej Thawj Chip yoov
Tus nqi tsav tsheb loj tshaj plaws nyob rau hauv precision casting tsis yog cov khoom siv lossis kev ua haujlwm. Nws yog rework tshwm sim los ntawm misaligned kev cia siab. Yog li peb embed engineering tshuaj xyuas rau hauv cov nqe lus hais - tsis yog kev coj ncaj ncees, tab sis raws li lub rooj vag nyuaj. Thaum tus neeg siv khoom xa daim duab kos rau lub cev tsis zoo lub siab lub cev, peb pab neeg tau chij peb yam hauv 48 teev:
- GD&T callouts uas tsis sib haum nrog cov kev xav tau ntawm casting (piv txwv li, qhia 0 ° cov qauv ntawm phab ntsa 300-mm)
- Nto tiav tsis tuaj yeem ua tiav yam tsis muaj kev sib tsoo thib ob (Ra 0.8 µm ntawm cov xuab zeb-cam khwb cia saum npoo yuav tsum + $ 12 / kg)
- Cov khoom siv tshwj xeeb uas tsis quav ntsej txog kev nthuav dav thermal tsis sib haum - zoo li kev sib koom ua ke ntawm cobalt alloy valve lub rooj zaum nrog lub cev carbon steel hauv kev pabcuam cyclic.
Peb tsis hais "yog" rau txhua qhov kev thov. Peb hais tias "Ntawm no yog qhov ua haujlwm, ntawm no yog vim li cas, thiab ntawm no yog tus nqi cuam tshuam ntawm txhua qhov kev xaiv." Qhov kev pom tseeb ntawd txiav NRE lub sijhawm los ntawm 40% ntawm qhov nruab nrab - thiab txhim kho kev ntseeg siab sai dua li cov ntawv pov thawj.
Rau engineers nrhiav precision casting qhov chaw chaw tsim tshuaj paus Hoobkas cov neeg koom tes, kev ntseeg siab tsis yog kev thov kev lag luam. Nws ntsuas tau: ≤0.8% PPM seem tus nqi ntawm cov khoom siv cobalt, ≤72-teev lub sijhawm ua haujlwm rau cov qauv castings, thiab xoom xa tuaj lig rau European OEMs hauv 2023. Nws tau xaiv tus neeg muag khoom uas kho koj cov duab kos tsis yog daim ntawv xaj - tab sis raws li kev sib koom ua haujlwm engineering cog lus. Qhov ntawd yog li cas lub hom phiaj-qhov tseem ceeb tau txais lawv qhov chaw nyob rau hauv cov txheej txheem uas poob nqi $ 28,000 / teev.
