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 "zoo txaus" machining. Koj xav tau qhov kev ruaj ntseg nyob rau hauv ± 0.005 hli, microstructure kev ncaj ncees thoob plaws tshav kub-kho AMS 5387 batches, thiab xoom kam rau ua rau cov khoom traceability gap. Yog vim li cas engineers nyob rau hauv North America, lub teb chaws Yelemees, thiab Singapore qhia qhov chaw los ntawm ib tug high precision CNC machining Hoobkas uas kho GD&T tsis yog cov ntaub ntawv-tab sis tsis yog kev sib tham physics.
Tiag tiag-lub ntiaj teb precision pib qhov twg kam rau ua tsis tau theoretical
Peb tau pom nws ob zaug xyoo no: Tier-1 cov khoom siv roj av tsis lees paub 47% ntawm cov qauv piston twj tso kua mis lub tog raj kheej los ntawm peb tus neeg muag khoom sib txawv - tsis yog rau saum npoo, tab sis vim qhov sib txawv ntawm qhov sib txawv tau dhau mus dhau 0.012 hli tom qab kev kho cua sov. Lub hauv paus ua rau? Tsis sib xws casting grain qauv pub rau hauv CNC ua haujlwm. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb daws qhov dej ntws ntws. Peb cov xuab zeb-casting foundry tswj cov nqi solidification rau hlau thiab stainless hlau castings siv real-time thermocouple daim ntawv qhia-tom qab ntawd xyuas txhua daim ntawv tuaj nrog spectrographic tsom xam ua ntej machining pib. Tsis muaj kev xav. Tsis muaj kev zam batch.
Qhov kev sib xyaw ntsug no-casting, multi-axis CNC, kev kho cua sov, thiab kev ua tiav hauv qab ib lub ru tsev ISO-raws li peb tuav geometric kam rau ua * los ntawm * tag nrho cov txheej txheem saw. Lub siab valve lub cev tsis yog tsuas yog machined los kos duab; Nws qhov kev poob qis yog ua qauv, nws qhov kev ua haujlwm tom qab kev ua haujlwm tsis zoo ntsuas ntawm Zeiss CMM, thiab nws qhov kawg hardness validated tiv thaiv ASTM E18. Peb xa cov khoom uas muaj sia nyob - tsis yog dhau - thawj qhov kev sim siab.
Superalloys tsis yog "nyuaj rau lub tshuab." Lawv tswj tsis tau
Qee tus neeg muag khoom kho cobalt-nickel alloys zoo li cov hlau tawv tawv. Lawv tsis yog. T800-raws li cov khoom xav tau cov tswv yim zoo uas txo cov cua sov-tsis yog cov khoom hnyav. Peb siv cov milling siab nrog PCD-tipped cutters ntawm AMS 5387 nozzles, tswj kev ruaj ntseg hauv qab Ra 0.4 µm thaum tuav phab ntsa thicknesses rau ± 0.008 hli. Vim li cas qhov no tseem ceeb? Vim hais tias qhov sib txawv ntawm 0.015-mm nyob rau hauv ib tug cobalt alloy plug hloov pauv coefficient los ntawm 11% nyob rau hauv high-pressure hydraulic circuits - thiab qhov no yog ntsuas nyob rau hauv lub teb tsis ua hauj lwm.
Peb lub khw hauv pem teb khiav tsib-axis DMG MORI NT series cov cav tov nrog kev soj ntsuam, tab sis qhov sib txawv tiag tiag yog kev qhuab qhia metallurgical. Peb koom tes tsim kho cua sov-kho lub voj voog nrog cov ntawv pov thawj cov khoom siv raw khoom - xyuas kom txhua AMS 5387 batch hits lub hom phiaj tensile zog (≥1,380 MPa) thiab elongation (≥12%) * ua ntej * txiav pib. Thaum ib tus neeg siv khoom thov kom peb rov ua dua qhov kev txiav tawm T800 alloy qhov chaw ncej rau lub tshuab hluav taws xob tsheb winch, peb thim rov qab-engineered tus thawj microstructure ntawm SEM / EDS tsom xam - tsis yog luam qhov ntev xwb. Qhov chaw khiav 32% ntev dua hauv kev pabcuam dua li OEM hloov.
Kev ntseeg tsis tau cog lus tseg. Nws tau tsim rau hauv cov txheej txheem tshuaj xyuas
"Full traceability" txhais tau tias ntau tshaj li ntau tus lej stamped rau ntawm lub thawv. Rau txhua qhov tseem ceeb - lub siab li qub, lub hauv paus twj tso kua mis, lub tog raj kheej vaj tse - peb teev: cov ntaub ntawv raw cov ntaub ntawv zeb xeem, cov txiaj ntsig X-ray, CNC program version IDs, CMM ntsuas cov ntaub ntawv, cov kab kos hluav taws xob kho cua sov, thiab cov ntawv soj ntsuam zaum kawg. Tag nrho cov ntaub ntawv khaws cia rau 10 xyoo. Cov neeg siv khoom nkag mus rau lawv qhov project keeb kwm ntawm kev ruaj ntseg portal-tsis yog PDFs email thaum ib tag hmo.
Tab sis kev pov thawj tshwm sim * thaum lub sij hawm * ntau lawm - tsis yog thaum kawg. Cov neeg ua haujlwm ua haujlwm hauv cov txheej txheem kuaj xyuas siv cov khoom sib piv ntawm cov yam ntxwv zoo li nozzle orifice geometry. Txhua qhov thib peb mus dhau los ntawm kev tshuaj xyuas CMM tag nrho tawm tsam thawj STEP cov ntaub ntawv - tsis yog qhov loj me xwb. Thiab yog-peb validate GD&T callouts zoo li txoj hauj lwm, profile, thiab runout * nyob rau hauv cov ntsiab lus *, tsis raws li ib tug cais nta. Yog tias koj daim duab qhia txog qhov sib xyaw ua ke ntawm lub ntsej muag rau lub ntsej muag flange txheeb ze rau bore axis, peb ntsuas nws li ntawd-siv datum simulators uas rov ua dua cov kev sib dhos tiag tiag.
Koj lub sijhawm teem sijhawm yuav tsum tsis txhob nyob ntawm qhov kev npaj muaj peev xwm ntawm tus neeg muag khoom
Kev txiav txim nruab nrab-ntev (50-500 pcs) feem ntau nyob ntawm cov chaw ua haujlwm tau zoo rau kev ua qauv lossis ntau lawm. Peb tau tsim peb cov dej num ua haujlwm rau nruab nrab hauv av: lean cell layouts, standardized fixturing rau tsev neeg ntawm twj tso kua mis Cheebtsam, thiab tsis stocks ntawm ntau cobalt thiab stainless qib. Thaum lub twj tso kua mis European OEM xav tau 120 AMS 5387 twj tso kua mis hauv 18 hnub - tom qab lawv tus neeg muag khoom ua ntej tsis tuaj txog hnub kawg ntawm 37 hnub - peb xa tuaj rau hnub 17. Tsis yog los ntawm kev ua haujlwm hnub so. Los ntawm kev tshem tawm cov voj voog rov ua haujlwm: casting porosity ntes tau ua ntej machining, cov cuab yeej coj los saib xyuas lub sijhawm, thiab kev tshuaj xyuas zaum kawg ua ntej ntim.
Qhov kev ntseeg ntawd txuas ntxiv mus rau kev txhawb nqa engineering. Peb tsis tsuas yog hais txog cov duab kos-peb chij qhov kev pheej hmoo ntawm kev tsim khoom * ua ntej * quoting: "Qhov no 0.3-mm phab ntsa ntawm lub valve vaj tsev yuav deflect thaum clamping; hais kom ntxiv ib ntus tav." Los yog: "Qhov kev teev tseg Ra 0.2 µm tiav yuav tsum tau electropolishing-tsis sib tsoo-uas ntxiv 3 hnub tab sis tiv thaiv micro-kawg pib." Tsis xav tsis thoob. Tsuas yog kev txiav txim siab hauv av hauv 12 xyoo ntawm kev ua haujlwm siab-alloy industrial Cheebtsam.
Rau lub hom phiaj tseem ceeb ntawm cov hlau qhov chaw - qhov uas tsis ua hauj lwm txhais tau hais tias downtime, kev nyab xeeb kev nyab xeeb, los yog warranty daim ntawv thov - precision tsis yog ib tug spec daim ntawv checkbox. Nws yog li cas koj tswj cov qauv nplej, tswj cov thermal distortion, thiab tswj qhov seem txuas ntxiv hla kev casting, machining, thiab tiav. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm li a high precision CNC machining Hoobkas vim nws kho txhua micron raws li qhov yuav tsum tau ua haujlwm - tsis yog lub hom phiaj. Koj qhov kev sib xyaw ua ke tom ntej tsis xav tau lwm nqe lus. Nws xav tau ib tus khub uas ntsuas kev ua tiav hauv kev ua haujlwm uptime, tsis yog kev xa khoom raws sijhawm.
