Qhov Tseem ceeb ntawm CNC Tshaj Tawm hauv Kev Tshaj Tawm 3C Electronics
Pom Zoo CNC Tshaj Tawm hauv Cheeb Tsam Electronics
Kev siv CNC machining yog qhov tseem ceeb rau kev tsim cov ntu sib txawv rau cov khoom siv hauv 3C electronics market. Qhov kev tshaj lij no pab rau tus tsim khoom tsim cov chaw nyob hauv aluminum rau cov smartphones thiab cov frame hauv magnesium rau cov laptops uas muaj qhov sib txawv me me li plus lossis minus 0.005mm. Cov lwm qhov kev cai no yog qhov tseem ceeb heev thaum tsim cov khoom me me xws li cov wireless earbuds thiab smartwatches uas txhua millimeter yog ib qhov tseem ceeb. Ib tug ntaub ntawv tshiab los ntawm International Journal of Advanced Manufacturing tau pom tias cov ntu tsim los ntawm CNC machines muaj qhov tsis muaj teeb meem hauv qhov ntau thiag li 92% kom compared to cov tsim los ntawm kev tsim traditional. Qhov no txhais tau tias muaj kev raug zoo dua thaum tsim ntau yam ntu, yog li ntawd yog vim li cas ntau tsev tsim khoom tau hloov mus siv CNC systems lawm.
Vim li cas CNC Machining yog tseem ceeb rau Smartphones, Laptops, thiab Wearables
Tom qhov kev lag luam tshwj tsis hlo tshaj tseem ceeb heev, CNC machining tau los ua txoj hauv kev rau kev tsim cov ntaub ntawv leeg uas peb pom nyob tam sim no. Xav txog cov ntaub ntawv xws li micro SIM card slots, cov kab roj siab tshaj plua tshaj 0.3mm thiab cov heatsink uas muaj kev kho. Cov ntxiv tshiab tshaj plaws ntawm 5 axis CNC machines tau tso cai rau kev ua haujlwm nrog cov khoom siv xws li 6061 aluminum. Cov chaw no ua haujlwm nrog RPM tshaj 15,000 thiab tuaj yeem tsim cov ntaub ntawv uas muaj qhov smoothness uas tsawg dua Ra 0.8 microns. Qhov kev finishing no yog ib qhov tseem ceeb rau ob qhov chaw: qhov ceev ntau thiab qhov zoo saum npoo. Ntawm qhov kev lag luam tshwj tsis hlo los ntawm Consumer Tech Association hais txog 2024, muaj ib qhov kawg tshaj plaws ntawm kev tsim kho rau cov khoom siv hauv kev lag luam no ntawm 2019 thiab 2023, nyob rau sab 42%. Yog li ntawd yog vim li cas cov neeg tsim khoom yuav tsum tau siv qhov precision no ntau dua li thaum kawg.
Kev pab pawg ntawm kev tsim kho tshaj tshaj plaws hauv kev lag luam tshwj tsis hlo
Nyob rau hlis tshiab tsib, peb tuaj yeem tsim tshuaj luv lwm li cas nyob rau hauv kev tsim kho sib thooj ntau dua ib txhiab ntawm yav dhau los. Yav tas los, tsov neeg tsis tau ua kom muaj qhov chaw tsim kho cov mobile phone thib ob, tab sis tam sim no txhua yam tsim kho yog tsim los los ntawm computer. Cov chaw tsim kho tsoom tseem ceeb no pab rau chaw tsim kho tsim kho cov rooj kawg zoo li cov smartwatch uas muaj qhov ncauj lossis tsim kho cov rooj kawg uas muaj qhov ncauj rau hauv speaker thiab tsim kho USB-C port uas muaj qhov ncav ncav tom qab. Qhov tseem ceeb tshaj plaws yog dab tsi? Yog Artificial intelligence uas tau xaiv rau hauv CNC machines. Chaw tsim kho uas siv nws hais tias lawv tuaj yeem tsim kho ntau dua 45% thaum siv nrog cov khoom nyuaj li carbon fiber. Nyob rau hauv qhab thawj xyoo dhau los, Journal of Materials Processing Technology tau pub tias li no.
