Dab tsi yog qhov yuav tsum tau rau CNC Machining raug nyob rau hauv Xov tooj ntawm tes Manufacturing?

1. Dimensional raug: Micrometer-qib tswj kev ua yuam kev yog lub hauv paus rau kev ua haujlwm.
Cov txheej txheem rau qhov tseeb qhov tseeb ntawm lub xov tooj ntawm tes cov qauv yog qhov ntau dua li cov txheej txheem rau kev siv tshuab, tshwj xeeb hauv cov xwm txheej hauv qab no:
Precision ntawm lub interface thiab qhov
Kev them nyiaj interface, SIM daim npav qhov, ntim qhov tseem ceeb, thiab lwm yam khoom yuav tsum muaj qhov ntev ntev ntawm ± 0.01mm. Piv txwv li, thaum CNC machining lub charging interface ntawm high -kawg hom lub xov tooj ntawm tes, tsib-axis linkage technology yog siv los ua kom zoo chamfer ntug ntawm lub interface. Qhov no ua kom paub tseeb tias qhov ntxig thiab tshem tawm quab yuam yog txawm thiab tsis muaj caij nyoog ntawm khawb. Yog tias qhov sib txawv loj dua 0.02mm, nws tuaj yeem ua rau lub plhaub tsis haum zoo lossis hloov cov duab.
Yuav ua li cas zoo ntawm nruab nrab ncej thiab screen haum ua ke
Yog hais tias qhov sib txawv ntawm cov hlau ncej thiab lub vijtsam yog ntau tshaj 0.05mm, yuav muaj teeb pom kev zoo lossis lub suab txawv txawv. Ib lub chaw tsim khoom siv "ib qho- lub sijhawm clamping kom ua tiav ntau- kev ua haujlwm sib luag", uas ua rau qhov tsis sib xws ntawm qhov nruab nrab ntawm ± 0.003mm. Lawv kuj siv qhov kev tshawb nrhiav hauv online los txhim kho txoj kev ua haujlwm hauv lub sijhawm tiag tiag, uas ua rau cov khoom sib dhos nce mus txog 99.2%.
Yuav ua li cas zoo lub internal structural seem pawg
Lub stacking kam rau ua rau sab hauv xws li kav hlau txais xov brackets thiab lub koob yees duab modules nyob rau hauv 5G smartphones yuav tsum tsawg tshaj li los yog sib npaug rau ± 0.02mm. Ib lub tuam txhab tshwj xeeb siv CNC machining kom cov threaded qhov ntawm lub koob yees duab bracket nyob rau hauv 0.005mm ntawm nws txoj hauj lwm npaj. Qhov no ua kom paub tseeb tias ntau lub koob yees duab modules yog coaxial thiab lub kaum sab xis ntawm kev pom tsis hloov thaum thaij duab.
2. Geometric kam rau ua: nruj txwv rau qhov nyuaj ntawm qhov chaw thiab cov qauv uas tsis ncaj
Lub creation ntawm frameless thiab curved mobile xov tooj yam ntxwv qhov chaw ua rau nws nyuaj heev kom tau raws li daim ntawv thiab txoj hauj lwm tolerances:
Kev tswj ntawm qhov sib xws
Qhov saum npoo uas txuas lub 3D iav rear npog rau cov hlau ncej yuav tsum tiaj tus mus rau hauv 0.01 hli thiab muaj ib tug nkhaus mus rau hauv 0.02 hli. Ib lub chaw tsim khoom lag luam siv tsib -axis CNC machining los tsim cov ncej nkhaus. Lawv kuj siv dynamic them algorithms los tiv thaiv lub tshuab vibration, uas ua rau qhov sib txawv ntawm lub nkhaus nto thiab iav txawm nyob rau ntawm 0.008mm. Qhov no zoo heev txhim kho cov dej tsis zoo.
Qhov tseeb ntawm qhov chaw rau qhov tsis sib xws
Txhawm rau ua kom cov teeb liab kis tau zoo dua, lub xov tooj ncej yuav tsum tau ua haujlwm nrog honeycomb - zoo li cov array ntawm qhov rau cov cua kub dissipation. Lub qhov nyob rau hauv lub thav duab ntawm ib hom xov tooj ntawm tes yog 0.5mm nyob rau hauv txoj kab uas hla, thiab qhov sib nrug ntawm lawv yuav tsum tsawg tshaj li los yog sib npaug zos rau 0.01mm. Siv CNC micro qhov machining thev naus laus zis thiab siab - cov khoom siv precision, nws muaj peev xwm ua tau 200 qhov hauv ib feeb thaum ua kom cov phab ntsa ntawm lub qhov du thiab tsis muaj burrs.
Qhov yuav tsum tau muaj rau ntau- cov khoom sib txuas
Muaj ntau ntau qhov kev txiav txim siab nyob rau hauv pob khawm qauv ntawm lub xov tooj ntawm tes foldable, thiab qhov yuam kev coaxiality yuav tsum tsawg dua lossis sib npaug li 0.005mm. Ib lub tuam txhab ntiav CNC machining los ua pob khawm ncej tes tsho. Lawv ua li no nyob rau hauv ib chav tsev uas nyob ntawm qhov kub thiab txias ntawm 20 ± 0.5℃thiab nrog ib tug huab cua bearing spindle. Qhov no txiav qhov yuam kev coaxiality ntawm 0.01 hli mus rau 0.003 hli, uas txhais tau hais tias lub neej folding yog tshaj 400,000 zaug.
3. Qhov Zoo ntawm Qhov Nto: Tsiv los ntawm kev ua haujlwm xav tau mus rau lub hom phiaj zoo nkauj
Lub peev xwm kho qhov chaw ntawm CNC machining muaj qhov cuam tshuam ncaj qha rau qhov zoo nkauj ntawm lub xov tooj ntawm tes:
Drawing thiab chamfering nrog high gloss tiav
Lub "pob zeb diamond txiav" tseem ceeb chamfer ntawm lub iPhone yuav tsum muaj qhov roughness ntawm Ra<0.1 μ m. One company employs CNC polishing technology and diamond cutting tools to keep the burr height of the chamfer edge under 0.002mm, which gives the surface a mirror-like shine. To draw wire, the pattern depth must be the same throughout, with a maximum difference of 0.005mm. This is done by using CNC programming to control the tool feed rate.
Ua ntej anodizing, qhov saum npoo yuav tsum tau pretreated.
Ua ntej anodizing, hlau thav duab yuav tsum tau polished nrog lub tshuab CNC kom tshem tawm cov cim kev ua haujlwm. Ib lub tuam txhab siv peb cov kauj ruam -" polishing ntxhib," "zoo polishing," thiab "ultrasonic tu"- kom txo qhov roughness ntawm Ra0.8 μ m rau Ra0.2 μ m. Qhov no ua rau oxide zaj duab xis thickness ntau dua los ntawm 30% thiab ua rau nws hnav ntau dua.
Kev ncaj ncees ntawm qhov chaw thaum lub sij hawm ua microstructure
Txhawm rau kom nws yooj yim dua rau kev khiav tawm, micro- nplai channel yuav tsum tau txiav rau hauv xov tooj. Lub tshav kub dissipation zawj ntawm ib tus qauv ntawm lub xov tooj ntawm tes yog 0.2mm dav thiab 0.5mm tob. CNC machining yuav tsum xyuas kom meej tias tsis muaj cov qog nqaij hlav hauv qab ntawm qhov zawj thiab tsis muaj qhov tawg tawg ntawm sab phab ntsa. Siv cov cuab yeej txiav coated thiab qis -kub txiav cov kua dej ua rau qhov tsis xws luag ntawm qhov chaw los ntawm 15% mus rau 0.5%.
4. Yuav ua li cas nyob rau hauv kev lag luam: Plaub lub ntsiab Technical Paths kom paub tseeb tias qhov tseeb
Txhim kho rau cov cuab yeej zoo dua: Tsib -axis txuas thiab cov cuab yeej siv tshuab nrog qhov tseeb siab heev
Tsib -axis CNC machining chaw nrog qhov rov ua dua qhov tseeb ntawm Tsawg dua lossis sib npaug rau ± 0.001mm feem ntau yog siv los ntawm siab-kawg xov tooj ntawm tes. Cov tshuab no tuaj yeem ua cov txheej txheem nyuaj nrog tsuas yog ib qho clamp. Piv txwv li, ib lub tuam txhab tsim cov cuab yeej nano meej tshuab uas txiav lub sij hawm nws siv los ua lub koob yees duab bracket los ntawm 8 feeb mus rau 3 feeb thiab ua kom qhov ntev ntawm qhov sib npaug li 50%.
Tsawg clamping thiab nrhiav pom hauv online yog ob txoj hauv kev los txhim kho cov txheej txheem.
Txoj kev "ib-lub sij hawm clamping kom ua tiav ntau- kev ua tiav" yuav txo qis ntawm tus naj npawb ntawm qhov chaw ua yuam kev uas tsim. Ib lub tuam txhab ntiav cov cuab yeej ntsuas kev sib koom ua ke hauv online txhawm rau taug qab qhov tseem ceeb ntawm lub sijhawm tiag tiag thaum ua cov txheej txheem. Thaum qhov sib txawv ntau tshaj 0.005mm, nws tam sim ntawd pib hloov kho, uas nce cov txiaj ntsig ntawm 92% mus rau 98%.
Kev tswj ib puag ncig: ib qho chaw ua haujlwm nrog qhov kub thiab txias tsis tu ncua
Txhawm rau khaws cov khoom ntawm lub xov tooj ntawm tes los ntawm warping, lawv yuav tsum tau ua tiav hauv chav tsev uas nyob ntawm qhov kub ntawm 20 ± 1 degree. Txhawm rau khaws cov khoom me me hauv huab cua qis dua 1000 particles / m³, qee lub Hoobkas tab tom tsim chav 1000 plua plav-rhiav pub dawb. Qhov no yog kom tsis txhob muaj qhov tsis zoo ntawm qhov chaw uas tuaj yeem tshwm sim thaum cov plua plav lo rau cov khoom.
Pob zeb diamond thiab txheej tshuab: Cov cuab yeej tshiab
Thaum ua hauj lwm nrog aluminium alloys nyuaj heev, pob zeb diamond txiav cov cuab yeej tuaj yeem ua rau saum npoo roughness poob qis dua Ra0.1 μ m. Cov cuab yeej coated, xws li cov uas muaj TiAlN txheej, tuaj yeem kav ntev li peb zaug thiab ua kom yooj yim hloov cov cuab yeej yam tsis muaj kev cuam tshuam qhov tseeb.
