Thaum cov neeg feem coob hnov 'cov khoom siv tshuab', lawv ua duab CAD kos duab lossis cov khoom ci ci hauv cov ntawv teev npe. Qhov ntawd yog qhov huv version. Qhov tseeb, qhov uas ua rau koj nyob rau hmo ntuj, yog hais txog kev hloov pauv ntawm tus qauv zoo tshaj plaws rau lub cev uas ua haujlwm tau zoo hauv kev thauj khoom, cua sov, thiab kev ntxhov siab. Qhov sib txawv ntawm kev kos duab thiab cov khoom siv ua haujlwm yog qhov kev lag luam tiag tiag nyob - thiab qhov twg nyiaj ntau tau poob ntawm qhov kev xav.
Lub Illusion ntawm Interchangeability
Ib qho ntawm cov kev xav tsis zoo tshaj plaws yog tias ib feem tsuas yog ib txheej ntawm qhov ntev. Koj tuaj yeem muaj ob tshuab qhov chaw los ntawm cov chaw muag khoom sib txawv uas ntsuas ib yam ntawm CMM, tsis tau ib qho ua tsis tiav hauv lub lis piam thiab lwm qhov kav ntau xyoo. Qhov sib txawv tsis yog nyob rau hauv geometry; nws yog nyob rau hauv cov nplej khiav ntawm forging, kho cua sov nkhaus, los yog cov residual kev nyuaj siab los ntawm machining. Kuv tau pom ib pawg ntawm cov twj tso kua mis uas dhau txhua qhov ntsuas qhov ntsuas tab sis snapped vim tias cov ntaub ntawv pov thawj tau raug faked - cov hlau muaj qhov tsis ncaj ncees lawm hardenability. Cov ntawv luam tsis tau qhia txog txoj kev metallurgical, tsuas yog qhov kawg hardness. Qhov ntawd yog $200k zaj lus qhia.
Qhov no yog qhov chaw foundry thiab machining keeb kwm yav dhau los ua tsis yog-negotiable. Koj tsis tuaj yeem tsuas yog outsource rau tus nqi pheej yig tshaj nrog lub tshuab CNC. Cov txheej txheem yog ib feem ntawm cov khoom. Piv txwv li, ntawm Qingdao Qiangsenyuan Technology (QSY), nrog lawv peb lub xyoo caum hauv casting thiab machining, lawv xav qhia rau koj tias lub plhaub pwm casting rau lub cev valve yuav muaj qhov sib txawv ntawm qhov ncaj ncees thiab ze-net zoo li piv rau cov xuab zeb casting, txawm nyob hauv tib qib ntawm stainless hlau. Qhov ntawd cuam tshuam li cas koj tsim koj cov kauj ruam tom ntej CNC machining - koj cov cuab yeej txoj kev, koj cov ntsiab lus clamping. Yog hais tias koj tshuab nws zoo li nws yog ib tug billet, koj tab tom qhia txog kev ntxhov siab lawv siv 30 xyoo kawm kom zam.
Nws yuam kom koj xav rov qab. Koj pib nrog hom tsis ua hauj lwm. Puas yog qaug zog? Hnav? Corrosion? Tom qab ntawd koj ua haujlwm rov qab rau cov khoom siv thiab cov txheej txheem tsim khoom. Ib feem rau cov khoom noj khoom haus ua los ntawm 316L stainless tsis yog hais txog corrosion kuj; nws yog li cas cov tshuab qhov chaw tiav lawm. Daim iav polish yuav zoo li zoo, tab sis nws puas tsim micro-crevices uas muaj cov kab mob harbor? Qee lub sij hawm ib qho kev tswj hwm, kev ntxhib los mos ntawm ib qho kev ua haujlwm tshwj xeeb yog qhov zoo dua. Daim ntawv spec yuav tsis qhia koj tias.
Cov khoom yog txheej txheem, tsis yog kev xaiv
Xaiv cov hlau tsis muaj hlau lossis npib tsib xee-raws li alloy los ntawm cov ntawv qhia zaub mov yog qhov pib ntawm kev sib tham, tsis yog qhov kawg. Noj Inconel 718. Cov khoom zoo heev. Tab sis yuav ua li cas nws cam khwb cia li cas nws yog forged tsim wildly txawv microstructures. Yog tias koj machining nws, qhov sib txawv ntawm hardness thiab work hardening nyiam yuav rhuav tshem koj cov cuab yeej yog tias koj siv tib yam tsis. QSY txoj haujlwm nrog cov alloys tshwj xeeb qhia qhov no - lawv yuav tsum tau kho lawv cov txheej txheem tag nrho raws li seb cov khoom tuaj yog los ntawm peev casting lossis wrought bar. Kev kho cua sov tom qab kev kub ntxhov rau kev ntxhov siab yog qhov tseem ceeb; hla nws, thiab ib feem yuav warp thaum kawg machining, tig ib tug precision tivthaiv rau hauv seem.
Kuv nco qab txog qhov project rau lub nplhaib turbine foob. Daim duab hu ua cobalt-based alloy, Stellite 6, tau teev tseg rau kev hnav tsis kam. Peb tau txais ib tug cast version. Nws machined txaus ntshai - tham, cuab yeej hnav yog astronomical. Qhov teeb meem? Cov txheej txheem casting tsim loj, nyuaj carbides nyob rau hauv ib tug brittle matrix. Qhov kev daws teeb meem, uas peb tuaj txog tom qab qee qhov kev sim siab thiab ua yuam kev, yog hloov mus rau cov hmoov hlau metallurgy version ntawm tib lub alloy, uas tau muab qhov zoo dua, zoo dua carbide faib. Nws machined huv si thiab ua tau zoo dua. Zaj lus qhia: lub npe alloy tsuas yog daim ntawv qhia; txoj kev tsim khoom yog cov txheej txheem ua noj. Koj tuaj yeem rhuav tshem daim ntawv qhia zoo nrog cov txheej txheem tsis zoo.
Qhov no yog vim li cas koom tes nrog tus neeg muag khoom uas tswj ob qho tib si casting thiab CNC machining nyob rau hauv ib lub ru tsev tsis yog khoom kim heev; nws yog ib qho kev pheej hmoo mitigation zoo. Thaum tus kws kho tshuab tuaj yeem taug kev rov qab mus rau tus thawj tswj xyuas thiab hais tias, Cov khoom no yog gummy, cov cuab yeej tau thauj khoom, lawv tuaj yeem taug qab nws rov qab rau qhov kub thiab txias. Qhov kev tawm tswv yim lub voj tsis pom rau lub tuam txhab lag luam ntshiab lossis lub khw uas tsuas yog machining. Ntawm qhov chaw zoo li QSY's, qhov kev sib koom ua ke yog cov khoom lag luam.
Tolerances: Tus nqi ntawm Perfection
Txhua tus xav tau kev zam nruj. Nws zoo nkaus li zoo. Tab sis qhia meej txog ± 0.01mm kam rau ua rau txhua qhov ntev ntawm kev ua haujlwm nyuaj yog txoj hauv kev zoo rau peb tus nqi thiab ncua qhov project. Koj yuav tsum nkag siab tias qhov kam rau ua yog dab tsi. Puas yog rau haum? Rau kev ua haujlwm? Rau qhov sib npaug? Feem ntau, tsuas yog ib lossis ob qhov tseem ceeb cuam tshuam xav tau qhov tseeb. Cov seem tuaj yeem ua rau xoob ntau.
