Thaum cov kws ua haujlwm qhia txog lub siab valve rau lub tshuab hydraulic ua haujlwm ntawm 420 bar - lossis thaum pab pawg saib xyuas hloov lub piston twj tso kua mis lub tog raj kheej nyob rau ntawm ntug dej hiav txwv roj - lawv tsis yog xav tau qhov chaw xwb. Lawv xav tau industrial qhov chaw Hoobkas cov neeg koom tes uas kho qhov ruaj khov zoo li daim ntawv cog lus, metallurgical zoo ib yam li cov lus cog tseg, thiab lub sijhawm xa khoom zoo li lub sijhawm kawg.
Tias yog vim li cas qhov kev ua haujlwm tseem ceeb-cov khoom siv hydraulic, tsheb engineering, roj & roj infrastructure, thiab cov twj tso kua mis ua haujlwm siab-nce ntxiv tig mus rau cov tuam txhab nrog kev sib xyaw ntsug, cov txheej txheem tshwj xeeb alloy, thiab xoom kam rau batch-rau-batch drift. Tsis yog txhua qhov chaw tsim khoom tuaj yeem tuav ± 0.015 hli ntawm lub rooj zaum cobalt-nickel nozzle. Tsis yog txhua lub khw CNC tuaj yeem tshuab AMS 5387 yam tsis muaj micro-cracking lossis tshav kub cuam tshuam cheeb tsam distortion. Thiab tsawg heev ua ke ob lub peev xwm nyob rau hauv ib qho ISO-raws li lub ru tsev-thaum tswj tag nrho cov ntaub ntawv traceability los ntawm T800 alloy ingot kom tiav tsis-tus qauv ncej cov menyuam.
Vim li cas Alloy Expertise tsis xaiv tau - Nws yog Thawj Lim
Cobalt-nickel superalloys zoo li AMS 5387 thiab T800 tsis raug xaiv rau kev zoo nkauj. Lawv tau teev nyob rau qhov twg yaig tsis kam, thermal stability siab tshaj 650 ° C, thiab tensile zog tshaj 1,100 MPa yog tsis sib tham. Tab sis lawv hardness (45-52 HRC as-cam khwb cia) thiab thermal conductivity tsawg ua rau lawv unforgiving nyob rau hauv machining. Peb tau pom cov neeg siv khoom nkoj kos duab piv txwv li cov txheej txheem toolpaths-thiab tau txais cov khoom nrog chatter marks, subsurface micro-fractures, los yog decarburization decarburization uas ua tsis tiav dye-penetrant kuaj.
Kev kho tsis yog nrawm dua spindles. Nws yog qhov tsim nyog txiav cov cuab yeej ua ntej, cov cuab yeej carbide nrog PVD TiAlN txheej, tswj cov dej txias ntws qis dua 12 ° C, thiab kev soj ntsuam xyuas hauv cov txheej txheem thermal. Ntawm peb lub chaw Qingdao, txhua txoj haujlwm cobalt alloy pib nrog kev tshuaj xyuas metallurgical - tsis yog ntawm chemistry, tab sis cov nplej loj faib thiab keeb kwm kev kho cua sov ua ntej. Peb tsuas yog muab ntawv pov thawj T800 daim ntawv pov thawj nrog cov ntaub ntawv xeem mills traceable rau ASTM B572 thiab AMS 5719. Tsis muaj kev zam.
Vertical Integration Uas ua tau kom ruaj khov
Feem ntau "ib-nres" cov khoom lag luam outsource casting lossis tiav. Qhov ntawd tsim peb lub ntsiab lus tsis ua haujlwm: tsis sib xws li-cam khwb cia microstructure cuam tshuam rau machinability; qhov ntev hloov thaum lub sij hawm kev ntxhov siab-relief annealing; thiab qhov chaw tiav qhov sib txawv ntawm cov neeg muag khoom. Peb tswj tag nrho plaub theem - kev nqis peev / xuab zeb casting, multi-axis CNC machining (txog 5-axis ib txhij), kev kho cua sov (xws li cov tshuaj annealing + aging ib AMS 2750), thiab ua haujlwm nto tiav (electropolishing, txhaj tshuaj peening, HVOF txheej).
Qhov no tseem ceeb tshaj plaws ntawm cov khoom xws li twj tso kua mis los yog winch center ncej chais. Cov no tsis yog static mounts-lawv nqus torsional shock, kis torque nyob rau hauv cyclic load, thiab interface nrog dynamic seals. Ib tug 0.03 hli sib txawv nyob rau hauv bearing phau ntawv roundness? Qhov ntawd ua kom nrawm nrawm los ntawm 300% hauv kev sim teb peb tau taug qab hla 17 tus neeg tsav nkoj North American. Peb cov kev ua haujlwm sib xyaw ua ke tshem tawm cov kev sib koom tes. CMM cov ntaub ntawv los ntawm ntxhib castings pub ncaj qha rau hauv CNC fixture tsim. Kev kho cua sov cycles raug kaw tawm tsam cov lej ua ntej sib tsoo zaum kawg. Tsis muaj dab tsi poob rau hauv kev txhais lus-los yog kev thauj mus los.
Qhov Zoo Uas Ua Hauv, Tsis Tshuaj Xyuas Rau
"Peb tshuaj xyuas txhua yam" tsis muaj qab hau yam tsis muaj lub rooj vag. Peb cov txheej txheem muaj plaub qhov nyuaj: (1) cov khoom siv raw khoom pov thawj siv OES spectrometry thiab kuaj ultrasonic; (2) nyob rau hauv-kev tshuaj xyuas tom qab ntxhib machining siv Zeiss CONTURA G2 CMM thiab Keyence VHX-7000 digital microscopy; (3) tom qab-kub-kho pov thawj ntawm hardness, grain ntws, thiab residual stress ntawm XRD; (4) qhov kawg ua haujlwm validation - suav nrog kev ntsuas siab txog li 600 bar thiab kev ntsuas qhov sib npaug ntawm cov khoom sib dhos.
Peb khaws tag nrho traceability: ntau tus lej, yaj cav, kho cua sov nkhaus, CMM daim ntawv qhia, thiab tus neeg teb xov tooj ID tau kos rau hauv txhua feem ntawm QR-coded daim ntawv lo. Thaum ib tug European OEM xav tau cov hauv paus-ua rau kev soj ntsuam ntawm lub valve tsev nyob qaug zog tawg, peb rub tag nrho cov ntaub ntawv ntau lawm-suav nrog spindle load graphs los ntawm qhov kawg tiav pass-hauv 90 feeb. Qhov ntawd tsis yog kev ua raws cai. Qhov ntawd yog kev ntseeg siab engineered rau hauv txhua txheej.
Txhim khu kev tsim khoom pib ntev ua ntej thawj nti ya. Nws pib nrog kev nkag siab tias yog vim li cas cobalt alloy ntsaws tsis ua haujlwm hauv cov pa roj qaub-tsis yog vim yog chemistry, tab sis vim yog intergranular oxidation ntawm machining-induced recast txheej. Nws txhais tau hais tias paub tias lub hauv paus xuab zeb-cam khwb cia hlau yuav tsum muaj cov tub ntxhais sib txawv rau cov tubrog nkoj thiab cov suab puam xa mus. Nws txhais tau hais tias kho GD&T callouts tsis yog cov ntaub ntawv, tab sis raws li lub hom phiaj ua haujlwm tau txhais ua cov txheej txheem tswj.
Rau engineers nrhiav lub hom phiaj-tseem ceeb hlau Cheebtsam, txoj cai industrial qhov chaw Hoobkas tsis yog tus nqi qis tshaj plaws. Nws yog tus khub uas nug txog koj qhov ua tsis tau zoo tshaj plaws ua ntej hais koj qhov kev txiav txim tom ntej - thiab tom qab ntawd tsim qhov kev ntsuas rau hauv txoj kev npaj. Qhov ntawd yog li cas kev ntseeg tau rov ua dua.
