CNC milling thiab tig yog ntau yam, raug nqi thiab raug, tab sis qhov ua tau rau CNC machined qhov chaw nthuav dav ntxiv txawm tias qhov kev ua tiav ntxiv.Cov kev xaiv yog dab tsi?Thaum lub suab zoo li ib lo lus nug yooj yim, cov lus teb nyuaj vim tias muaj ntau yam los xav txog.
Ua ntej, qhov tiav yog dab tsi?Puas yog txhawm rau txhim kho kev zoo nkauj lossis kev ua haujlwm?Yog tias tom kawg, dab tsi ntawm kev ua haujlwm yuav tsum tau txhim kho?Corrosion resistance, deg hardness, hnav tsis kam lossis EMI / RFI shielding?Cov no tsuas yog qee cov lus nug uas yuav tsum tau teb yog li, piv txwv li tus tsim qauv paub tias lub hom phiaj yog dab tsi, cia peb saib ntau yam kev xaiv.
Ua tiav rau CNC machined hlau thiab alloy qauv qauv
Tshaj li 40 xyoo dhau los, Prototype Projects 'machinists tau hais kom tsim cov khoom los ntawm ntau cov hlau thiab alloys rau kev siv hauv ntau qhov kev lag luam.CNC machined qhov chaw yog niaj hnub deburred, ntxuav thiab degreased tab sis, tom qab ntawd, kev xaiv ntawm cov tiav tiav yog dav heev.
Tam sim no, peb cov neeg siv khoom nyiam cov hlau yog aluminium alloy, stainless hlau.
Tseem nrov tab sis teev tsawg dua yog tooj liab, tooj dag, phosphor bronze, me me steel, cuab yeej steel.Txij lub sij hawm, cov neeg siv khoom kuj thov CNC machining nyob rau hauv ntau lwm yam hlau thiab alloys.
Hlau thiab alloys tuaj yeem ua tiav hauv ntau txoj kev sib txawv.Piv txwv li, txhuas feem ntau tuaj yeem ua kom pom tseeb anodised, hardcoat anodised, lossis xim dub lossis xim anodised, txawm tias 6082 aluminium alloy txais anodising tsawg dua li lwm qib.Ib yam li ntawd, 5083 tooling phaj peb siv tuaj yeem tsim cov cim tshwj xeeb.Qhov kev xaiv nyob ntawm seb qhov yuav tsum tau ua yog txhawm rau txhim kho kev zoo nkauj lossis kev ua tau zoo (tshwj xeeb yog corrosion kuj lossis hnav tsis kam).
Stainless hlau yog inherently corrosion resistant tab sis tej zaum cov neeg muas zaub qhia meej ntxiv finishes.Electropolishing, piv txwv li, ua kom tiav qhov zoo thiab tshem tawm cov burrs thiab cov npoo ntse los ntawm qhov sib txawv.Ntawm qhov tod tes, yog tias qhov tawv tawv, hnav tsis kam lossis qaug zog yuav tsum tau txhim kho, ob qho tib si 304 thiab 316 stainless hlau tuaj yeem raug nitrided lossis nitrocarburised.
Cov hlau me me tau txais txiaj ntsig los ntawm tej zaum qhov kev xaiv dav tshaj plaws ntawm kev ua tiav.Cov kev xaiv muaj xws li kev pleev xim ntub dej, pleev xim rau electrophoretic, hmoov txheej, electroplating, tshuaj pleev xim dub, hlaws blasting, electropolishing, rooj plaub tawv, titanium nitriding (TiN) txheej, nitriding thiab nitrocarburising.
Tooj thiab tooj dag feem ntau tau teev tseg rau qhov chaw ua haujlwm, tsis tas yuav tsum tau ua tiav tom qab machining.Yog tias tsim nyog, txawm li cas los xij, cov khoom tuaj yeem polished manually, electropolished, electroplated, vapor blasted, lacquered los yog kho nrog tshuaj tua kab mob.
Cov kev ua tiav tau teev tseg saum toj no tsis yog tsuas yog muaj rau cov hlau thiab alloys.Peb ib txwm zoo siab los tham txog kev ua tiav nrog cov neeg siv khoom thiab peb sim pab txhua qhov chaw peb tuaj yeem ua tau.
Finishes rau CNC machined yas prototype qhov chaw
Raws li cov hlau thiab alloy qhov chaw, tag nrho cov khoom yas peb CNC tshuab yog deburred, ntxuav thiab degreased tab sis, tom qab ntawd, cov kev xaiv tiav yuav txawv.
Raws li feem ntau ntawm cov neeg muas zaub thov CNC machined qauv yas qhov chaw nyob rau hauv acetal (dub los yog ntuj) los yog acrylic, peb tuav cov no nyob rau hauv Tshuag rau peb Express CNC machining kev pab cuam.Acetal tsis tuaj yeem txais cov khoom tiav ntxiv, yog li cov khoom feem ntau muab 'raws li machined'.Acrylic, ua kom pom tseeb, feem ntau polished kom muab lub iav zoo li lub ntsej muag.Qhov no tuaj yeem ua tiav manually nrog cov qib zoo ntawm cov abrasive, lossis nrog cov nplaim polishing.Yog tias xav tau, acrylic tuaj yeem pleev xim nrog cov xim acrylic lossis lub tshuab nqus tsev hlau kom ua tiav qhov pom kev zoo.
Tshaj li acetal thiab acrylic, peb CNC tshuab qauv qhov chaw los ntawm ntau yam ntawm engineering plastics.
Qee qhov no yooj yim ua kom tiav dua li lwm tus, yog li koj ib txwm txais tos los tham txog cov ntaub ntawv thiab ua tiav nrog peb ua ntej thov qhov kev tsocai.Nyob ntawm cov yas, peb tuaj yeem xuab zeb, prime thiab xim qhov chaw, polish lawv (manually los yog nplaim), electroless phaj los yog nqus metallise.Rau qee cov yas uas tsis muaj zog saum npoo av, tshwj xeeb nto npaj nrog primer lossis plasma kho yog tsim nyog.
Dimensional soj ntsuam ntawm CNC machined qauv qhov chaw
Ib qho laj thawj vim li cas cov neeg siv khoom xaiv kom muaj qhov qauv CNC machined es tsis yog 3D luam tawm yog qhov tseeb dua.Peb qhov kev kam rau siab rau CNC machined qhov chaw yog ± 0.1mm, txawm hais tias qhov ntev yog ib txwm tuav kom nruj dua, nyob ntawm cov khoom siv thiab cov duab geometry.Peb ib txwm tshawb xyuas tus neeg sawv cev qhov ntev tom qab machining, thiab cov neeg siv khoom tuaj yeem nug txog cov yam ntxwv tshwj xeeb los kuaj thiab.
Feem ntau cov kev ntsuas tuaj yeem raug coj los ntawm tes callipers lossis micrometers tab sis peb lub tshuab ntsuas kev sib koom tes (CMM) yog qhov zoo tshaj plaws rau kev tshuaj xyuas ntau dua.Qhov no yuav siv sij hawm thiab tsis muaj nrog peb cov kev pabcuam Express CNC tab sis nws yog qhov nrawm dua li xa cov khoom mus rau lwm tus neeg rau CMM tshuaj xyuas.Qhov tsuas yog qhov tshwj xeeb yog thaum yuav tsum tau ua kom tiav, tag nrho cov txheej txheem tshuaj xyuas CMM, lossis ib pawg ntawm cov khoom tau raug tshuab thiab yuav tsum tau kuaj xyuas 100 feem pua.
Kev xaiv los ua ke rau CNC machined prototype qhov chaw
'Kev sib dhos' ntawm no txhais tau hais tias txhua yam los ntawm kev ntxig Helicoils rau hauv cov khoom siv txhuas hlau lossis cov xov ntxig rau hauv cov yas, mus txog rau kev txhim kho cov kabmob thiab siv cov ntawv luam tawm.Feem ntau peb raug hais kom ua ke CNC machined qhov chaw nrog rau lwm yam qauv, txawm tias lawv tau CNC machined, 3D luam tawm los yog lub tshuab nqus tsev cam khwb cia.
Qhov tseeb, peb yuav lees paub yuav luag txhua theem ntawm kev sib dhos ntawm cov qauv ua haujlwm lossis cov qauv pom, suav nrog cov qauv qauv lossis cov txheej txheem tawm ntawm lub txee raws li qhov tsim nyog.Lwm qhov kev xaiv yog overmould CNC machined qhov chaw nrog polyurethane los ntawm lub tshuab nqus tsev casting.
