Thaum koj lub valve tsis ua haujlwm ntawm 3,000 psi - lossis cobalt-alloy twj tso kua mis vaj tse tawg nyob rau hauv thermal cycling - koj tsis xav tau lwm tus neeg muag khoom uas "kho cov alloys." Koj xav tau ib alloy precision machining Hoobkas uas twb tau daws cov kev ua tsis tiav ntawm lub khw hauv pem teb.
Peb tau pom nws ua ntej: North American OEM ncua kev xa khoom peb zaug vim tias lawv cov neeg muag khoom yav dhau los tsis lees paub GD&T callouts ntawm AMS 5387 lub tog raj kheej vaj tsev. Ib feem dhau qhov ntsuas qhov ntsuas-tab sis tsis ua tiav kev sim siab. Vim li cas? Vim tias qhov kev ncaj ncees ntawm qhov chaw thiab microstructural zoo ib yam tsis tau txheeb xyuas nrog rau geometry. Qhov ntawd tsis yog qhov yuam kev machining. Nws yog qhov sib txawv ntawm qhov system.
Qhov tseeb tiag pib qhov twg casting xaus - thiab qhov twg machining pib
Feem ntau cov neeg muag khoom kho casting thiab CNC raws li cais silos. Ib pab neeg nchuav hlau. Lwm lub tshuab nws. Tab sis cov khoom siv siab ntev-tshwj xeeb tshaj yog nyob rau hauv cov roj & roj, hnyav hydraulics, lossis lub hom phiaj tseem ceeb ntawm cov twj tso kua mis sib dhos-thov kom txuas ntxiv mus rau ob theem. Dimensional stability tsis yog hais txog kev zam nruj ntawm CMM daim ntawv tshaj tawm. Nws yog hais txog yuav ua li cas residual stress los ntawm solidification cuam tshuam nrog txiav quab yuam thaum lub sij hawm multi-axis milling. Nws yog hais txog yuav ua li cas kev kho cua sov tom qab machining cuam tshuam cov ciam teb cohesion hauv T800 cobalt-based khoom.
Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., casting tsis yog prep ua hauj lwm rau machining-nws yog thawj kauj ruam precision. Lawv cov ISO-raws li qhov chaw ua haujlwm sib npaug ntawm peev casting thiab xuab zeb casting kab calibrated tshwj xeeb rau cobalt-nickel, stainless hlau, thiab qib high-zog hlau. Raw khoom traceability pib ntawm daim ntawv pov thawj zeb-tsis yog ntawm qhov chaw txais khoom. Txhua AMS 5387 batch tau txais kev kuaj xyuas spectrographic ua ntej nchuav. Txhua T800 alloy ntau yog kub-kho ib AMS 2750, nrog rau cov cav tov rauv khi ncaj qha mus rau feem serial tooj.
Qhov kev sib xyaw ntsug no tshem tawm cov nqi zais loj tshaj plaws hauv kev tsim cov khoom siv high-alloy: rework tshwm sim los ntawm cov kev xav tsis sib xws ntawm metallurgical. Thaum tib pab neeg tswj hwm ob lub pwm kab noj hniav thiab cov cuab yeej cuab tam, lawv paub tseeb tias qhov twg yuav tsum siv cov tshuab cais tawm - thiab qhov twg yuav tawm hauv Tshuag rau kev txiav txim siab kawg.
Koj tsis yuav cov khoom. Koj tab tom yuav kev ntseeg tau ua haujlwm
Saib lawv cov piston twj tso kua mis lub tog raj kheej vaj tse. Tsis yog generic "CNC machined qhov chaw" - tab sis units nrog ± 0.005 hli bore concentricity, hardened nto ntsib ASTM A957 Class 1, thiab sab hauv ntws txoj kev polished rau Ra 0.4 µm. Los yog lawv cov cobalt alloy nozzles: tsim los ntawm AMS 5387, tom qab ntawd ua tiav nrog electrochemical deburring kom tshem tawm cov micro-notches uas pib qaug zog tawg ntawm 120 Hz vibration frequencies.
Cov no tsis yog specs rub los ntawm phau ntawv teev npe. Lawv yog cov txiaj ntsig tau lees paub thoob plaws 17,000+ cov sijhawm tsim khoom ntawm cov khoom siv hauv ntiaj teb tiag tiag - suav nrog cov twj tso kua mis hauv qab dej hiav txwv khiav tsis tu ncua ntawm 120 ° C thiab engineering tsheb winch center ncej chais raug rau 400,000-cycle torsional loads.
Ib txhia yuav sib cav hais tias casting + machining ntxiv complexity thiab txhuas lub sij hawm. Tab sis nyob rau hauv kev xyaum, lawv lean workflow compresses lub voj voog lub sij hawm * vim * tsis muaj kev ncua ncua sij hawm ntawm foundry thiab tshuab khw. Tsis txhob tos rau castings kom txias, nkoj, tshuaj xyuas, thiab rov ua dua. Tsis muaj kev rov tsim dua tshiab thaum lub geometry as-casting tsis phim CAM software kev xav. Ib pab neeg muaj cov txheej txheem tag nrho - los ntawm kev kos duab validation los ntawm kev xeem ua haujlwm zaum kawg.
Kev ua tau zoo tsis raug tshuaj xyuas hauv
Taug kev mus rau hauv lawv qhov chaw kuaj xyuas thiab koj yuav pom ntau dua CMMs. Koj yuav pom cov kws sib piv kho qhov muag txheeb xyuas cov xov flank kaum ntawm cobalt alloy plugs. Koj yuav pom dye-penetrant chaw nres tsheb siv ntawm txhua lub siab lub cev lub cev - tsis yog cov qauv xwb. Koj yuav pom cov ntaub ntawv ntsuam xyuas cov ntaub ntawv hla-hais txog cov xov tooj cua sov, nrog cov ntaub ntawv tensile nkag rau hauv cov ntaub ntawv ruaj ntseg nkag tau rau cov neeg siv khoom raws li kev thov.
Tsis muaj "AQL sampling." Tsis muaj "kev tshuaj ntsuam zaum kawg dhau/tsis tau" checkboxes. Txhua qhov tseem ceeb tau ntsuas ob zaug - ib zaug tom qab roughing, ib zaug tom qab ua tiav - nrog kev sib txawv ntawm qhov sib txawv ntawm ib qho. Txhua qhov saum npoo tiav raug txheeb xyuas raws li cov neeg siv khoom tshwj xeeb cov kev xav tau: tsis yog Ra qhov tseem ceeb, tab sis kev txwv tsis pub muaj kev txwv, qhov siab tshaj plaws suav qhov pib, thiab kev coj tus qauv nkhaus qhov xav tau.
Qhov kev qhuab qhia no muab qee yam tsis tshua muaj nyob rau hauv kev tsim khoom thoob ntiaj teb: kev xa khoom raws li qhov nruab nrab-ntim xaj (50-500 pcs / ntau) yam tsis muaj kev cuam tshuam thawj zaug. Prototypes nkoj hauv 12 hnub ua haujlwm. Kev txiav txim ntau lawm ntaus> 98% raws sij hawm xa tuaj-txawm tias muaj cov txheej txheem sib xyaw ua ke xws li peev-cam khwb cia + 5-axis-machined + lub tshuab nqus tsev-brazed sib dhos.
Dab tsi ua rau alloy precision machining Hoobkas sib txawv?
Peb yam cais lawv los ntawm cov khw muag khoom ua haujlwm dav dav:
- Khoom siv tau zoo: Tsis yog "machining cobalt alloys," tab sis paub yuav ua li cas T800 tus nqi ua haujlwm-hardening hloov pauv tus nqi pub ntawm 220 m / min spindle ceev - thiab kho cov dej txias kom haum.
- Lub luag haujlwm lav ris: Lawv tsis nug "Koj xav tau dab tsi kam rau ua?" Lawv nug "Yuav ua li cas tsis ua hauj lwm hom koj sim tiv thaiv?" Tom qab ntawd kho cov txheej txheem tswj rau cov lus teb ntawd.
- Engineering pob tshab: Kev tshuaj xyuas kos duab suav nrog cov ntawv cim xws li "Lub vojvoog no yuav ntxiab slag hauv kev nqis peev casting-pom kom nce mus rau R0.8 kom huv si sau" lossis "GD&T thav duab ntawm no tsis sib haum nrog qhov ua tiav ntawm kev ncaj ncees-qhia kom txo qis profile siab ntev los ntawm 0.01 hli thiab ntxiv cov lus piav qhia saum npoo."
Yog tias koj qhov project tom ntej no cuam tshuam nrog lub siab li qub, lub hauv paus twj tso kua mis, lossis cov khoom tsis yog cobalt-nickel uas xav tau qhov ua tau zoo siab-tsis txhob pib nrog RFQs. Pib nrog kev tshuaj xyuas manufacturability. Vim tias qhov muaj zog tshaj plaws tsis yog ib qho uas nruj tshaj plaws spec. Nws yog qhov tsim nyog thawj zaug - txhua lub sijhawm.
