Nyob rau hauv lub relentless nrhiav kev siab dua, ceev, thiab efficiency nyob rau hauvprecision machining, txhua feem ntawm aCNC systemua lub luag haujlwm tseem ceeb.Lub spindle backplate, zoo li yooj yim interface ntawm spindle thiab cov cuab yeej txiav los yog chuck, tau tshwm sim los ua qhov tseem ceeb cuam tshuam rau kev ua tau zoo tag nrho. Kev lig kev cai tsim los ntawm cam khwb cia hlau los yog hlau, backplates yog tam sim no tau re-engineered siv cov khoom zoo li6061 aluminium. Tsab ntawv xov xwm no tshuaj xyuas seb qhov kev hloov pauv no tau daws cov teeb meem ntev npaum li cas hauv kev vibration damping, thermal tswj, thiab kev sib hloov sib npaug, yog li teeb tsa cov qauv ntsuas tshiab rau qhov tseeb hauv qhov chaw tsim khoom txij li xyoo 2025.
Txoj kev tshawb fawb
1.Txoj Kev Tsim
Ib txoj kev tshawb fawb ntau yam tau ua haujlwm los xyuas kom meej thiab txhim khu kev qha:
●Kev sib piv cov khoom siv: 6061-T6 txhuas backplates tau ncaj qha piv nrog Qib 30 cam khwb cia hlau backplates ntawm zoo tib yam qhov ntev.
●Simulation qauv: FEA simulations siv Siemens NX software tau ua los tshuaj xyuas deformation nyob rau hauv centrifugal rog thiab thermal gradients.
●Kev sau cov ntaub ntawv ua haujlwm: Kev vibration, kub, thiab cov ntaub ntawv nto tiav tau nkag los ntawm ntau lub CNC milling chaw khiav haujlwm zoo ib yam nrog ob hom backplates.
2.Reproducibility
Txhua qhov kev sim ua raws cov qauv, fea qauv tsis sib xws (suav nrog mesh kev sau ntawv muaj cov ncauj lus kom ntxaws rau kev tso cai rau kev kawm ywj siab thiab rov ua dua tshiab ntawm txoj kev kawm.
Cov txiaj ntsig thiab Kev Ntsuam Xyuas
1.Kev vibration Damping thiab Dynamic Stability
Comparative Damping Performance (Measured Loss Factor):
| Khoom siv | Loss Factor (η) | Ntuj zaus (Hz) | Amplitude txo vs. Cam khwb cia hlau |
| Cast Iron (Qib 30) | 0.001-0.002 Nws | 1,250 ib | Lub hauv paus |
| 6061-T6 Aluminium | 0.003-0.005 Nws | 1,580 ib | 40% |
Lub peev xwm ntau dua damping ntawm 6061 aluminium zoo attenuates high-frequency vibrations originating los ntawm cov txheej txheem txiav. Qhov kev txo qis hauv kev sib tham ncaj qha cuam tshuam nrog 15% kev txhim kho hauv qhov ua tiav zoo (raws li ntsuas los ntawm Ra qhov tseem ceeb) hauv kev ua tiav.
2.Thermal Management
Raws li kev ua haujlwm tas mus li, 6061 aluminium backplates mus txog qhov sib npaug ntawm 25% sai dua li cov hlau cam khwb cia. FEA cov txiaj ntsig, pom nyob rau hauv, qhia qhov sib txawv ntawm qhov kub thiab txias, txo qis thermal-induced positional drift. Cov yam ntxwv no yog qhov tseem ceeb rau kev ua haujlwm machining lub sijhawm ntev uas yuav tsum tau ua kom ntev ntev.
3.Qhov hnyav thiab kev ua haujlwm zoo
Qhov 65% txo qis hauv kev sib hloov loj txo qis lub sijhawm ntawm inertia. Qhov no txhais ua kom nrawm nrawm nrawm thiab lub sijhawm qeeb, txo qis lub sijhawm tsis txiav hauv cov cuab yeej hloov pauv-kev ua haujlwm hnyav los ntawm qhov nruab nrab ntawm 8%.
Kev sib tham
1.Kev txhais cov kev tshawb nrhiav
Qhov kev ua tau zoo tshaj ntawm 6061 txhuas yog vim nws cov khoom siv tshwj xeeb. Lub alloy lub hauv paus damping yam ntxwv stems los ntawm nws microstructural grain ciam teb, uas dissipate vibrational zog raws li tshav kub. Nws cov thermal conductivity siab (kwv yees li 5 npaug ntawm cov hlau cam khwb cia) ua kom yooj yim rau cov cua sov sai sai, tiv thaiv cov chaw kub kub uas tuaj yeem ua rau qhov tsis ruaj khov.
2.Kev txwv
Txoj kev tshawb no tsom mus rau 6061-T6, uas yog siv dav dav. Lwm cov qib txhuas (piv txwv li, 7075) lossis cov khoom sib xyaw ua ke tuaj yeem ua rau cov txiaj ntsig sib txawv. Tsis tas li ntawd, cov yam ntxwv hnav ntev ntev nyob rau hauv cov xwm txheej tsis huv tsis yog ib feem ntawm qhov kev ntsuam xyuas thawj zaug.
3.Tswv yim cuam tshuam rau manufacturers
Rau cov khw muag khoom siv lub hom phiaj kom ua kom tau qhov tseeb thiab dhau los, siv 6061 aluminium backplates nthuav qhia txoj hauv kev txhim kho kom zoo. Cov txiaj ntsig tau tshaj tawm hauv:
● High-speed machining (HSM) daim ntawv thov.
● Kev ua haujlwm xav tau qhov zoo ntawm qhov chaw tiav (piv txwv li, pwm thiab tuag ua).
● Ib puag ncig uas hloov txoj haujlwm sai yog qhov tseem ceeb.
Cov neeg tsim khoom yuav tsum xyuas kom meej tias lub backplate yog qhov sib npaug ntawm qhov sib npaug tom qab mounting cov cuab yeej kom siv tag nrho cov khoom zoo.
Xaus
Cov pov thawj lees paub tias 6061 txhuas CNC spindle backplates muaj qhov tseem ceeb, ntsuas tau zoo dua li cov khoom siv ib txwm muaj. Los ntawm kev txhim kho damping muaj peev xwm, txhim kho thermal stability, thiab txo cov kev sib hloov loj, lawv ncaj qha ua rau cov machining raug siab dua, zoo dua saum npoo zoo, thiab nce kev ua haujlwm zoo. Kev saws me nyuam ntawm cov khoom no sawv cev rau ib kauj ruam ntawm kev sib tw rau pem hauv ntej hauv precision engineering. Cov kev tshawb fawb yav tom ntej yuav tsum tshawb xyuas qhov kev ua tau zoo ntawm cov qauv tsim hybrid thiab kev siv cov kev kho tshwj xeeb saum npoo kom txuas ntxiv kev pab cuam lub neej nyob rau hauv abrasive tej yam kev mob.
