Peb muab ntau yam ntawm CNC machining cov kev pab cuam nrog ib tug tag nrho saj zawg zog tov rau txhua yam ntawm precision tivthaiv mus rau ntev fabrications.
Dab tsi yog qhov feem ntau aluminium CNC machining txheej txheem?
CNC milling tshuabyog cov feem ntau thiab ntau yam ntawm machining txhuas qhov chaw. Lub tshuab siv rotating tej cuab yeej kom zoo thiab precisely carve cov ntaub ntawv los ntawm ib tug nyob ruaj ruaj thaiv cov khoom.
Cov tsoos milling tshuabhloov mus rau hauv "machining centers" nyob rau hauv 1960s ua tsaug rau qhov tuaj txog ntawm computer numerical control (CNC) systems, automatic tool changers and tool carousels. Cov tshuab no muaj nyob rau hauv 2- txog 12-axis configurations, txawm hais tias 3 mus rau 5-axis yog qhov siv dav tshaj plaws.
CNC hlau lathes, los yog CNC hlau tig chaw, tuav ruaj khov thiab tig lub workpiece thaum lub taub hau tuav lub cuab yeej txiav los yog laum tawm tsam nws. Cov tshuab no tso cai rau kev tshem tawm cov khoom siv meej heev thiab cov neeg tsim khoom siv lawv hauv ntau qhov kev lag luam.
Kev ua haujlwm ntawm tshuab dhos xws li drilling, shaping, slot-making, tapping, threading thiab tapering. CNC hlau lathes tau nrawm hloov cov laus, ntau phau ntawv ntau lawm qauv vim lawv qhov yooj yim ntawm kev teeb tsa, kev ua haujlwm, rov ua dua thiab raug.
CNC plasma cutterscua sov compressed cua mus rau qhov kub siab heev los tsim ib "plasma arc" muaj peev xwm ntawm melting hlau mus txog rau ntiv tes tuab. Cov ntaub ntawv yog tuav ncaj nraim rau lub rooj txiav thiab lub computer tswj txoj kev ntawm lub taub hau teeb. Cov cua compressed tshuab tawm cov hlau kub molten, yog li txiav los ntawm cov khoom. Plasma cutters yog ceev, meej, kuj yooj yim rau siv thiab pheej yig, thiab manufacturers siv lawv nyob rau hauv ntau industries.
CNC laser tshuabyog yaj, hlawv los yog vaporize cov ntaub ntawv tam sim ntawd los tsim ib tug txiav ntug. Zoo ib yam li cov plasma cutter, cov ntaub ntawv yog tuav ncaj nraim rau lub rooj txiav thiab lub khoos phis tawj tswj txoj hauv kev ntawm lub zog loj laser beam.
Laser cutters siv lub zog tsawg dua li cov plasma cutters thiab yog qhov tseeb dua, tshwj xeeb tshaj yog thaum txiav cov ntawv nyias. Txawm li cas los xij, tsuas yog cov laser cutters uas muaj zog thiab kim tshaj plaws uas muaj peev xwm txiav los ntawm cov ntaub ntawv tuab lossis tuab.
CNC dej cutterssiv cov dav hlau siab heev ntawm cov dej yuam los ntawm qhov nqaim nozzle los txiav cov khoom. Dej ntawm nws tus kheej yog txaus los txiav los ntawm cov ntaub ntawv mos xws li ntoo lossis roj hmab. Txhawm rau txiav los ntawm cov ntaub ntawv nyuaj xws li hlau lossis pob zeb, cov neeg ua haujlwm feem ntau sib tov cov tshuaj abrasive nrog dej.
Cov dej cutters tsis kub cov khoom xws li plasma thiab laser cutters. Qhov no txhais tau hais tias muaj qhov kub thiab txias yuav tsis hlawv, warp lossis hloov nws cov qauv. Nws kuj tseem pab txo cov khoom pov tseg thiab tso cai rau cov duab txiav los ntawm ib daim ntawv kom muab tso rau (los yog zes) ze rau ua ke.
Peb cov kev pabcuam CNC machining:
Khoov
Peb tuaj yeem muab cov raj khoov, cov menyuam khoov, ncab txoj kev sib sau thiab ntws cov kev pabcuam rau peb cov neeg siv khoom, siv cov txheej txheem tsim thiab sib koom ua ke lwm cov kev pabcuam machining kom ua tiav cov txiaj ntsig zoo.
Drilling
Peb cov kev xaiv ntawm plaub-axis CNC cov chaw thiab cov kev cai laum khoom tso cai rau peb los ua ke cov tswv yim daws teeb meem thiab lub sijhawm ua haujlwm ceev kom tau txais koj cov txiaj ntsig zoo tshaj plaws hauv lub sijhawm luv tshaj plaws.
Milling
Peb tuaj yeem ua tau raws li ntau qhov kev xav tau ntawm milling, los ntawm cov khoom me me mus rau cov profiles loj. Nrog peb cov plaub-axis CNC centres, peb tuaj yeem tsim cov khoom sib txawv nrog ntau yam ntawm cov qhov, qhov thiab cov duab.
Tig
Peb lub tshuab tig thiab tho txawv cov kev pabcuam feem ntau yog plaub zaug sai dua li phau ntawv sib npaug. Muab kev txhim khu kev qha 99.9% qhov tseeb, CNC tig muab cov txiaj ntsig zoo thiab raws sijhawm.
