Puas yog nws tsim nyog los ua CNC precision machining tom qab hlau 3D luam ntawv?

1. Lub hauv paus ntawm kev siv tshuab: muaj peev xwm ntawm cov khoom siv ntxiv thiab cov khoom rho tawm ua haujlwm ua ke
Lub ntsiab sib txawv ntawm CNC precision machining thiab hlau 3D luam ntawv yog dab tsi ua rau lawv ua hauj lwm ua ke nyob rau hauv lub manufacturing txheej txheem:
Txoj kev sib txawv rau daim ntawv
Hlau 3D luam ntawv ua tej yam los ntawm melting hlau hmoov ib txheej ntawm ib lub sij hawm. Qhov saum npoo qhia cov txheej txheem txheej txheem thiab yaj cov kab hauv pas dej. Tej zaum yuav muaj teeb meem nrog lub microstructure, xws li hmoov uas tsis tau fused thiab micropores. CNC precision machining siv cov cuab yeej txiav kom tshem tawm cov ntaub ntawv, tsim ib daim iav nyhuv nrog Ra0.8 μm lossis qis dua, thiab nws tuaj yeem tswj qhov ntev ntawm qhov ntev mus rau hauv ± 0.01 hli.
Kev txwv ntawm cov txheej txheem muaj peev xwm
3D luam ntawv muaj qee qhov txiaj ntsig. Piv txwv li, nws tuaj yeem ua rau cov txheej txheem nyuaj uas nyuaj rau kev siv cov txheej txheem qub, xws li kev ua kom txias txias, cov txheej txheem lattice hnyav, thiab kab noj hniav nrog ntau lub kaum ntse ntse. Piv txwv li, ib lub cav aviation cav siv 3D luam ntawv los ua rau sab hauv hollow, uas txiav qhov hnyav los ntawm 40% thaum ua kom lub zog ntawm cov qauv.
Cov txiaj ntsig ntawm CNC machining: Kev ua haujlwm zoo dua rau cov ntaub ntawv zoo li cov dav hlau thiab lub tog raj kheej, thiab tsis tas yuav tiv nrog cov khoom txhawb nqa seem. Piv txwv li, CNC milling ua rau saum npoo roughness ntawm ib lub tsheb kis tau tus mob Ra0.4 μm, uas ua tau raws li qhov hnav tsis kam xav tau rau siab - kev sib hloov ceev.
Qhov sib txawv ntawm hybrid manufacturing
Txoj kev hybrid ntawm "3D luam ntawv + CNC precision machining" tau dhau los ua tus qauv hauv kev lag luam. Piv txwv li, ib lub tuam txhab uas ua cov pwm precision siv 3D luam ntawv los ua cov pwm tseem ceeb nrog peb txheej ntawm cov cua txias sab hauv. Tom qab ntawd, lawv ntiav CNC machining los ua kom cov txheej txheem txias 30% ntau dua thiab txiav lub sijhawm xa khoom los ntawm 14 hnub mus rau 5 hnub.
2. Kev lag luam xav tau: ntau yam txheej txheem rau saum npoo roughness
Cov kev lag luam sib txawv muaj cov kev xav tau sib txawv rau qhov zoo, uas cuam tshuam ncaj qha rau kev xav tau CNC precision machining:
Teb ntawm aerospace
Cov khoom yuav tsum muaj peev xwm tswj tau cov xwm txheej hnyav (qhov kub thiab txias, kev kub siab, thiab kev ntxhov siab), thiab qhov tsis zoo ntawm qhov chaw tuaj yeem ua rau qaug zog tawg.
Ib qho piv txwv yog tias CNC machining txo qhov roughness ntawm lub sealing nto los ntawm Ra12 μ m rau Ra0.8 μ m thaum ib hom foob pob hluav taws cav nozzle yog 3D luam tawm. Qhov no txuas ntxiv lub neej kev sib khi ntawm qhov kub thiab txias ntawm 50 zaug txog 200 zaug.
Xaiv cov txheej txheem: Cov khoom tseem ceeb, xws li sealing nto thiab mating nto, yuav tsum yog CNC precision machined. Tsis yog -cov kabmob nto tuaj yeem khaws cov ntawv luam tawm kom txuag tau qhov hnyav.
Field of Medical implants
Qhov tseem ceeb yuav tsum tau: Surface roughness cuam tshuam qhov muaj feem ntawm cov pob txha ntawm tes txuas thiab cov kab mob loj hlob.
Lub titanium alloy hip ob leeg prosthesis yuav tsum muaj qhov zoo ntawm Ra1.5-2.5 μ m kom cov pob txha loj tuaj rau hauv nws. Ib lub tuam txhab ua cov khoom siv dag zog siv 3D luam ntawv. Tom qab ntawd, ua kom lub ntsej muag smoother rau Ra0.8 μ m, lawv siv kev sib xyaw ntawm cov tshuaj polishing thiab CNC polishing. Qhov no khaws cov qauv microporous uas tau tsim los ntawm kev luam ntawv, uas ua rau lub cev sib haum nrog cov khoom muaj sia.
Xaiv cov txheej txheem kom raug: Qhov chaw ua haujlwm xav tau CNC precision txiav, whereas cov txheej txheem nto tuaj yeem khaws cov ntawv luam tawm.
Hauv ntiaj teb cov neeg siv khoom siv hluav taws xob
Qhov smoothness ntawm qhov chaw yog qhov tseem ceeb uas cuam tshuam qhov khoom zoo li cas thiab nws ua haujlwm zoo li cas.
Nyob rau hauv ib tug raug scenario, CNC machining txo tus nto roughness ntawm ib tug 3D- luam tawm lub xov tooj txawb lub koob yees duab mount los ntawm Ra3.2 μ m rau Ra0.05 μ m. Qhov no ua rau lub teeb pom kev pom ntau dua, los ntawm 85% mus rau 92%, uas yog qhov kev sib txuas lus laser xav tau.
Xaiv cov txheej txheem: Qhov chaw kho qhov muag yuav tsum tau ua nrog CNC precision, qhov chaw ntawm cov txheej txheem tuaj yeem khaws cov ntawv luam tawm.
Lub zog thiab Pwm Kev Lag Luam: Qhov zoo ntawm qhov chaw yuav tsum sib npaug ntawm kev tiv thaiv corrosion thiab ua haujlwm yooj yim nrog.
Ib tug 3D- luam ntawv txhaj tshuaj pwm tub ntxhais rau lub tsheb tau siv los ua ib qho chaw txias txias. Tom qab ntawd, nws tau sandblasted kom lub nto tsis ntxhib, mus ntawm Ra15 μm mus rau Ra6.3 μ m. Qhov no nce pwm lub neej ntawm 100,000 siv rau 500,000 siv.
Xaiv cov txheej txheem: Rau qhov chaw uas tsis kov, koj tuaj yeem siv qis - cov txheej txheem nqi xws li sandblasting. Rau qhov chaw uas kov, koj xav tau CNC precision machining.
3. Tus nqi -effectiveness: Economic Logic ntawm xaiv ib tug txheej txheem
Txhawm rau txiav txim siab seb puas siv CNC precision machining, koj yuav tsum ua tib zoo saib cov kev ua tau zoo, lub voj voog xa khoom, thiab cov nqi tsim khoom.
Kev ntsuam xyuas ntawm kev ua tau zoo
Cov txheej txheem nyuaj: Yog tias cov khoom muaj cov yam ntxwv uas nyuaj rau kev tsim khoom nrog CNC (xws li qhov hla ntawm sab hauv lossis nyias- cov qauv phab ntsa), 3D luam ntawv yuav yog ib qho kev xaiv. Piv txwv li, 3D luam ntawv ua rau tag nrho cov combustion chamber ntawm lub dav hlau muab lub cav, uas zam cov kev nyuaj siab concentration nyuaj uas yuav tshwm sim nrog ib txwm welding txoj kev.
Qhov yuav tsum tau ua kom raug: CNC precision machining yog xav tau yog tias qhov yuav tsum tau ua siab ntev siab dua li qhov 3D luam ntawv tuaj yeem ua tau (xws li ± 0.01mm). Piv txwv li, ib qho dawb paug rau siab - iav precision yog ua los ntawm 3D luam ntawv, thiab CNC sib tsoo nce tus hniav profile raug los ntawm IT8 qib mus rau IT5 qib.
Optimizing lub voj voog xa khoom
Rau kev txiav txim sai, 3D luam ntawv tuaj yeem hla txoj kev txhim kho pwm thiab teb sai sai rau "tsim luam ntawv xa khoom." Piv txwv li, lub tuam txhab tsheb tshiab lub zog siv 3D luam ntawv los ua cov qauv roj teeb pob bracket. Tag nrho cov txheej txheem, los ntawm kev tsim mus rau kev sib dhos, tsuas yog siv 48 teev.
Yog tias batch loj loj (ntau tshaj 1000 daim), CNC machining yuav pheej yig dua rau batch ntau lawm. Lub tuam txhab tsim cov khoom lag luam tuaj yeem siv CNC batch ua cov kev sib txuas ntawm aluminium alloy los ua ib yam khoom 60% pheej yig dua 3D luam ntawv.
Tswj tus nqi tag nrho ntawm kev xa khoom
Thaum siv CNC machining, koj yuav tsum xav txog cov nuj nqis implicit xws li programming, clamping, thiab pwm kuaj. Ntawm qhov tod tes, 3D luam ntawv tuaj yeem txo tus nqi ntawm cov cuab yeej thiab kev pheej hmoo ntawm kev tsim iterations. Piv txwv li, 3D luam ntawv tuaj yeem ua rau cov txheej txheem nyuaj txhua lub sijhawm, txiav tawm lub sijhawm xav tau los hloov cov cuab yeej thiab cov txheej txheem los ntawm 70%.
Kev siv cov khoom siv: CNC machining ib txwm siv 50% mus rau 70% ntawm cov khoom, thaum 3D luam ntawv tuaj yeem siv ntau dua 90%. Piv txwv li, 3D luam ntawv ua ib yam khoom titanium alloy, uas raug nqi 40% tsawg dua CNC milling.
