1. Txiav txim siab qhov yuav tsum tau ua ntawm qhov chaw.
2. txheeb xyuas cov khoom siv uas siv los ua qhov chaw.
3. Xav txog lwm yam kev ua haujlwm thib ob.
Ua ntej koj qhov yuav tsum tau ua:
1. Ib puag ncig: Rau ntau, qhov no yog qhov tseem ceeb tshaj plaws. Ib puag ncig tej yam yuav muaj xws li kub thiab txias tsis kam, nplaim retardancy, los yog UV thiab tshuaj tiv thaiv.
Nyob ntawm daim ntawv thov, koj cov khoom yuav tsum yog zaub mov -qib lossis kev kho mob- qib. Xav txog tag nrho cov ntawv thov rau ib feem. Piv txwv li, cov khoom siv kho mob yuav tsum tiv taus qhov kub siab heev ntawm autoclave lossis hnyav tshuaj sterilization ntawm kev siv.
2. Hluav taws xob: Qhov no tuaj yeem suav nrog ntau yam ntawm daim ntawv thov - muaj feem cuam tshuam. Ib feem yuav tsum yog conductive lossis insulating. Nws yuav tsum tau dissipate hluav taws xob zoo li qub. Nyob rau hauv ob qho tib si, xaiv txoj cai hlau los yog yas resin yog qhov tseem ceeb.
3. Mechanical: Lub zog tuaj ntau yam. Ib feem yuav tsum tau poob rau txhua qhov chaw ntawm qhov txuas ntxiv los ntawm nruj mus rau qhov hloov pauv. Nws yuav xav tau tensile los yog compressive zog, los yog muaj peev xwm tiv taus tej yam. Tej zaum nws yuav tsum tau hnav- tiv taus lossis muab lubrication ua haujlwm raws li cov kabmob. Cov ntaub ntawv uas ua tau raws li cov kev cai no muaj, thiab qee qhov muaj txiaj ntsig zoo dua li lwm tus.
4. Loj: Thaum machining tuaj yeem tsim ntau qhov ntau thiab tsawg, ib feem qhov ntev yuav raug txwv los ntawm qhov siab tshaj plaws ntawm cov khoom siv hauv Tshuag.
5. Tus nqi: Tus nqi tuaj yeem yog qhov tseem ceeb, feem ntau poob tom qab qhov tseem ceeb thiab cov kev xaiv zoo.
Txheeb xyuas cov khoom siv Machining uas nquag siv
Tau ntau xyoo, peb cov engineers tau txheeb xyuas cov kev xaiv ntawm cov khoom tsim nyog rau kev ua haujlwm, thiab cov ntaub ntawv no tau txais kev xaiv nrov rau peb cov neeg siv khoom.
Rau cov hlau, cov no suav nrog txhuas, tooj dag, tooj liab, stainless hlau, thiab hlau. Hauv cov yas, cov neeg tsim qauv feem ntau xaiv polyetheretherketone (PEEK), ABS, acetal, nylon, polycarbonate, polyvinyl chloride (PVC), siab - ntom polyethylene, thiab qis- ntom polyethylene. Protolabs muaj ntau dua 40 qib sib txawv ntawm cov yas thiab hlau. Qee cov yam ntxwv tseem ceeb ntawm cov khoom siv machining nrov tshaj plaws suav nrog:
ABS thiab Acetal
1. ABS muaj lub zog muaj zog, tsis tshua muaj thermal conductivity, thiab tsis tshua muaj coefficient ntawm kev sib txhuam.
2. Acetal muaj lub zog txhua yam, zoo qhov ruaj khov, thiab tsis tshua muaj dej nqus. PEEK vs. Ultem
1. PEEK muaj kev tiv thaiv zoo heev, tsis tshua muaj dej noo, thiab tsis tshua muaj coefficient ntawm kev sib txhuam.
2. Ultem (PEI) muaj lub zog siab heev, nruj, tshuaj tiv thaiv, thiab siab dielectric zog.
Aluminium 6061 vs . 7075
1. 6061 muaj kev ua tau zoo heev, tus nqi qis, thiab ntau yam.
2. 7075 muaj lub zog siab, hardness, tsis muaj qhov hnyav, thiab ua haujlwm kub.
Kev xaiv tiav thiab kev xaiv txheej txheem
Ntxiv nrog rau kev xaiv cov khoom siv, cov txheej txheem ua tiav theem nrab yuav tsum tau txiav txim siab. Piv txwv li, yog tias cov khoom xaiv yog ib qho ntawm cov khoom siv txhuas muaj (6061 thiab 7075), ntau qhov kev kho saum npoo yuav tsum tau txiav txim siab. Anodizing yog qhov zoo dua rau kev ua haujlwm ntev, muab koj tus nqi - zoo thiab siab -zoo tag nrho- hauv - ib qho kev daws teeb meem.
