Kev ua tiav yog kauj ruam kawg hauv CNC machining thiab siv tau los txhim kho qhov zoo ntawm cov khoom. Kev ua tiav tuaj yeem tshem tawm cov qhov tsis zoo ntawm qhov tsos, txhim kho cov teebmeem pom ntawm cov khoom, thiab txhim kho lub zog kho tshuab lossis kev ua haujlwm hluav taws xob.
Ntsib nrog ntau txoj kev kho saum npoo av, cov thawj tswj khoom thiab cov neeg tsim qauv xaiv qhov kev daws teeb meem zoo tshaj plaws li cas? Tsis txhob txhawj, cov kev kho mob hauv qab no muaj lawv tus kheej qhov zoo. Tsuav koj nkag siab txog cov yam ntxwv ntawm txhua txoj kev, koj tuaj yeem ntxiv cov ntsiab lus rau cov khoom.

Txheej txheem ua haujlwm
Qhov chaw ntawm cov khoom tsim los ntawm CNC machining hu ua "machined surface". Qhov chaw yog ntxhib tab sis muaj qhov ntev nruj, uas txaus rau qee qhov kev siv engineering. Qhov nruab nrab roughness yog li 3.2μm, thiab tsis tas yuav ua tom qab, yog li qhov ua tau zoo ntawm kev tsim khoom yog siab.
Rau cov ntawv thov uas qhov tseeb ntawm qhov ntev tseem ceeb dua li qhov tsos, qhov chaw machining no txaus. Txawm li cas los xij, vim nws qhov roughness thiab tsis muaj txheej tiv thaiv, qhov chaw muaj peev xwm tiv thaiv tsis zoo thiab yooj yim khawb thiab hnav. Zuag qhia tag nrho, qhov sib piv ntawm tus nqi / kev ua tau zoo txaus rau qee kis, thaum kev kho ntxiv ntawm qhov chaw yuav tsum tau ua qhov twg kev tiv thaiv siab.
Anodizing yog ib qho txheej txheem electrochemical uas tuaj yeem tsim cov zaj duab xis oxide tuab dua thiab ntom dua ntawm qhov chaw ntawm CNC machined qhov chaw, yog li txhim kho kev ua tau zoo tiv thaiv.
Cov txheej txheem no tsuas yog siv tau rau ntawm cov hlau txhuas lossis titanium vim tias lawv muaj cov hluav taws xob zoo heev. Thaum lub sijhawm ua cov txheej txheem, cov hlau sib xyaw raug muab tso rau hauv lub tank electrolyte uas muaj kua qaub los ua lub anode, thiab tam sim no siv los sib xyaw cov ions oxygen hauv cov kua qaub nrog cov hlau sib xyaw ntawm qhov chaw los tsim cov zaj duab xis oxide.
Muaj ob hom anodization tseem ceeb. Lawv yog tib yam txheej txheem, tab sis xav tau cov khoom kom raug muab tso rau hauv cov kua qaub sulfuric ntawm ntau qhov sib txawv. Hom II hu ua "decorative anodization", uas tsim cov txheej txheem pob tshab lossis xim nrog tuab ntawm 4-25 μm; hom III hu ua "hard coat anodization", uas muaj txheej txheem tuab ntawm 125 μm thiab hnav-resistant dua.
Zuag qhia tag nrho, cov xim anodized yog cov khoom siv ruaj khov thiab ruaj khov, ua rau lawv zoo tagnrho rau cov qhov hauv tsev thiab cov khoom me me uas xav tau kev ua haujlwm siab. Nws yog ib qho ntawm cov kev xaiv zoo tshaj plaws ntawm CNC machined finishes, tab sis tus nqi kuj siab.
Kev txheej hmoov
Cov txheej hmoov zoo ib yam li cov xim tsuag. Ua ntej, kev kho phosphating lossis chromate tiv thaiv xeb raug siv rau ntawm qhov chaw ntawm qhov khoom, thiab tom qab ntawd cov khoom raug txau nrog rab phom electrostatic hmoov qhuav thiab kho hauv qhov cub saum 200 ° C. Cov txheej txheem ntau txheej tuaj yeem ncav cuag qhov tuab ntawm 72μm.
Kev kho mob no nws tus kheej tuaj yeem tsim cov zaj duab xis tiv thaiv rau CNC qhov chaw, uas yog tawv, hnav-resistant thiab zoo nkauj. Nws tuaj yeem ua ke nrog sandblasting los txhim kho kev ua haujlwm tiv thaiv xeb thiab qhov sib npaug ntawm qhov chaw.
Tsis zoo li anodizing, hmoov txheej yog sib xws nrog txhua yam hlau, muaj zog toughness, thiab siab impact resistant, ua rau nws haum rau ntau yam kev siv, tshwj xeeb tshaj yog kev siv tub rog.
Tiam sis cov hmoov txheej tsis zoo thiab tsis haum rau cov khoom me me lossis cov khoom sab hauv. Ntxiv mus, tus nqi siab dua yuav txwv nws txoj kev siv rau hauv kev tsim khoom loj.
Kev siv cov hlaws dai los ntxiv qhov tiav matte lossis satin rau ntawm qhov chaw CNC machined. Thaum lub sijhawm no, cua siab thawb ntau lab lub hlaws dai iav tawm tsam qhov chaw, tshem tawm cov cim cuab yeej thiab qhov tsis zoo kom tsim tau cov qauv zoo sib xws. Sib piv rau lwm yam tiav xws li anodizing thiab hmoov txheej, kev siv cov hlaws dai tsis hloov pauv qhov chaw los ntawm tshuaj lom neeg lossis tshuab - nws hloov qhov tsos pom. Tsis zoo li hmoov txheej uas ntxiv cov khoom siv, kev siv cov hlaws dai txo qis vim nws tshem tawm me me ntawm cov khoom siv. Qhov no yog qhov tseem ceeb yog tias koj qhov chaw muaj kev kam rau siab.
Kev siv cov hlaws dai yog ib qho ntawm cov khoom tiav uas pheej yig dua, tab sis yuav tsum tau ua haujlwm tes. Cov neeg uas xav txog nws yuav tsum npaj nyiaj rau tus neeg teb xov tooj uas tau kawm tiav raws li txoj cai vim tias qhov zoo ntawm qhov tiav nyob ntawm kev txawj ntse. Hom hlaws dai thiab qhov loj me uas siv kuj cuam tshuam rau cov txiaj ntsig. Txawm hais tias yog txheej txheem tes, kev siv cov hlaws dai tseem yog ib qho kev xaiv uas siv tau ntau yam thiab pheej yig rau cov khoom tiav CNC uas ua tiav hauv qhov kev kam rau siab.
Cov lus qhia rau kev ua tiav CNC machined qhov chaw
Hauv ntej, rau cov khoom uas tsis xav tau daim duab zoo meej tab sis yuav tsum khaws lawv qhov loj me qub, kev kho qhov chaw tom qab ua tiav xws li anodizing lossis hmoov txheej tuaj yeem yog qhov kev xaiv zoo. Anodizing txhim kho lub peev xwm tiv thaiv ntawm cov khoom txhuas lossis titanium. Thaum ib feem tsis tuaj yeem anodized tab sis xav tau lub zog thiab kev cuam tshuam, hmoov txheej muab lwm txoj hauv kev. Thaum kawg, yog tias kev siv nyiaj tsim nyog tseem ceeb dua li kev kam rau siab - thiab qhov khoom tsis xav tau qhov chaw du - sandblasting tej zaum yuav yog txoj hauv kev zoo dua.
Cov kws ua haujlwm, cov neeg tsim qauv, thiab cov thawj tswj khoom zoo tshaj plaws kom sab laj nrog cov kws tshaj lij tsim khoom kom paub tseeb tias lawv ua qhov kev xaiv zoo rau lawv qhov project tom ntej.
