Mill tiav 6061-T6 txhuas ntawv yog muab raws nraim li nws tawm hauv lub tshuab dov: tsis muaj chromate conversion txheej, tsis muaj anodised txheej, tsis muaj xim thiab tsis muaj mechanically polished lub ntsej muag. Hauv kev yuav cov ntaub ntawv, qhov xwm txheej saum npoo tau hais tias yog zeb tiav lossis los ntawm kev siv rau qhov chaw dov nrog lub ntsiab lus ntawm qhov roughness, thiab cov neeg yuav khoom uas tsis meej pem zeb tiav nrog cov tshuaj pleev ib ce tiav yog cov uas tsis lees paub cov khoom zoo ntawm cov khoom-hauv.
Dab tsi Mill Finish Surface muaj
Lub ntsej muag zeb tiav yog lub ntsej muag dov nqa ib lub ntuj oxide nyias ntawm qhov kev txiav txim ntawm ob peb nanometers, lub teeb residual dov lubricant zaj duab xis thiab yob kev ntxhib los mos hloov los ntawm kev ua haujlwm yob. Pom pom yob cov cim, faint longitudinal streaks thiab me ntsis qhov sib txawv ntawm sheen ntawm coils yog ib txwm thiab tsis muaj qhov tsis xws luag hauv kev nkag siab ntawm lub tiaj tus -rolled specification. Dab tsi yog qhov tsis pom zoo yog embedded hlau los yog yob- hauv cov khib nyiab, khawb tob hauv pawg, dej staining los ntawm condensation thaum caij tsheb thauj mus los, lossis ntug kev puas tsuaj los ntawm kev sib tsoo.
Nto Roughness thiab tsos Cia siab
| Yam khoom | Tej yam mob saum npoo | Hom roughness, Ra |
|---|---|---|
| Txias- yob daim ntawv | Fine yob kev ntxhib los mos, uniform sheen | kwv yees . 0.3-1.0 micrometer |
| Kub-rolled phaj | Coarser kev ntxhib los mos, pom ntau yob cov cim | kwv yees . 0.8-1.6 micrometer |
| Daim ntawv nrog tiv thaiv zaj duab xis | PVC zaj duab xis ntawm ib lossis ob lub ntsej muag | Zaj duab xis thickness feem ntau 50-100 micrometer |
Roughness qhov tseem ceeb yog hais raws li ib txwm vim hais tias yob kev ntxhib los mos yog ib tug zeb - tej yam txawv txawv. Qhov twg daim duab qhia txog qhov siab tshaj plaws Ra, qhov yuav tsum tau muaj nyob rau ntawm qhov kev txiav txim, txwv tsis pub lub zeb muab cov qauv lag luam nto. Mill tiav daim ntawv tsis haum rau cov hniav zoo nkauj anodising, qhov twg yuav tsum tau npaj tshwj xeeb los yog polished nto.
Cov khoom siv, Tempers thiab Tolerances
Cov hlau feem ntau yog txiav txim siab nyob rau hauv T6 temper rau lub zog thiab nyob rau hauv T651 los yog T451 rau phaj uas yuav tsum machined ntau thiab yuav tsum tuav flatness tom qab tshem tawm cov khoom. Tolerances raug muab cais los ntawm qhov chaw nyob. Nyob rau hauv ASTM B209 / B209M thickness kam rau ua nws txawv nrog txiav txim thickness thiab dav; nyob rau hauv European EN 485 series lub dimension thiab daim ntawv tolerances rau kub- dov thiab txias- dov khoom yog muab nyob rau hauv lawv tus kheej qhov chaw ntawm tus qauv, thiab ob qho tib si txheem thiab nruj cov chav kawm yuav raug hu mus. Flatness, camber, squareness thiab ntug mob yuav tsum tau thov kom meej meej yog hais tias lawv tseem ceeb rau lub downstream kev khiav hauj lwm, vim hais tias lawv tsis implied los ntawm zeb tiav.
Kev tsim kho, kev tsim khoom thiab kev tsim khoom
Qhov qis -lub zog nto oxide tsis muaj kev tiv thaiv staining. Daim ntawv yuav tsum tau muab khaws cia rau hauv tsev, tawm hauv pem teb, muaj qhov cua txaus thiab tsis muaj kev sib cuag ncaj qha ntawm cov hlau tsis sib xws; condensation cycles nruab nrab ntawm hmo txias thiab sov hnub yog qhov ib txwm ua rau cov dawb oxide tawg pom nyob rau hauv tus me nyuam. Kev tiv thaiv PVC zaj duab xis muaj qhov txwv lub neej txee, feem ntau nyob ib ncig ntawm rau lub hlis nyob rau hauv temperate tej yam kev mob thiab tsawg dua nyob rau hauv cov huab cua kub, vim hais tias cov nplaum residue yuav nyuaj rau tshem tawm. Shearing thiab guillotining yuav tsum siv cov cuab yeej tshwj xeeb uas tsis muaj cov pa roj carbon- steel swarf, txij li cov khoom siv hlau ua rau pom qhov tsaus nti tom qab anodising. Laser txiav nrog nitrogen pab ua ib tug huv ntug ntawm 6061, waterjet txiav zam tej tshav kub- cuam tshuam cheeb tsam, thiab routed los yog sawn npoo yuav tsum tau deburred ua ntej ib tug ua tiav tiav. Roller leveling restores flatness ntawm daim ntawv txiav thiab yuav tsum tau nqa tawm ua ntej ntsuas qhov kawg flatness.
Qhia txog Mill Finish lossis Pretreated Surface
Mill tiav yog qhov kev xaiv zoo thaum qhov yuav raug machined, tsim, welded thiab tom qab ntawd tiav, vim hais tias ib qho pre-thov txheej yuav raug puas tsuaj los ntawm cov txheej txheem fabrication. Ib qho chaw pretreated, los ntawm qhov sib txawv, yog tsim nyog thaum daim ntawv xa mus rau ib txoj kab uas tsis tuaj yeem nqa tawm kev tu, xws li cov anodising txuas ntxiv lossis coil txheej kab, lossis thaum xav tau kev tiv thaiv corrosion thaum lub sijhawm thauj khoom hauv hiav txwv ntev. Qhov kev xaiv thib peb yog cov yeeb yaj kiab tiv thaiv, uas tiv thaiv qhov chaw los ntawm kev puas tsuaj tab sis tsis hloov nws cov chemistry thiab yuav tsum tau muab tshem tawm hauv cov khoom siv zaj duab xis lub qhov rais. Txawm li cas los xij yog xaiv txoj kev, qhov kev txiav txim yuav tsum yog lub npe ntawm qhov chaw, qhov kub thiab txias, lub thickness kam rau ua thiab qhov yuav tsum tau flatness, txij li plaub yam khoom no txiav txim siab seb lub coil xa tuaj yeem siv tau.
Tej kev siv
Mill tiav 6061-T6 daim ntawv thiab phaj mus rau hauv machined fixtures thiab jigs, base plates thiab tooling, brackets thiab gussets, chassis thiab thav duab Cheebtsam, hluav taws xob enclosures, taug kev thiab platform seem, thauj lub cev panels uas yuav pleev xim rau, thiab dav fabrication qhov twg tsos yog teem los ntawm lub kawg txheej. Nyob rau hauv txhua tus ntawm cov no siv cov saum npoo zoo yuav tsum tau tsav los ntawm cov kauj ruam tiav, tsis yog los ntawm tus me nyuam.
Cov lus nug nquag
Q:Puas yog zeb tiav daim ntawv tib yam li cov ntawv txhuam los yog polished?
A: Tsis yog. Mill tiav yog raws li - dov nto nrog lub teeb yob zoo nkauj thiab lub ntuj oxide. Txhuam thiab polished tiav yog tsim los ntawm kev ua haujlwm sib cais thiab raug nqi raws li.
Q:Puas tuaj yeem zeb tiav 6061-T6 tau anodised ncaj qha?
A: Nws tuaj yeem ua tau, tab sis cov yeeb yaj kiab anodic rov tsim dua qhov kev ntxhib los mos, yog li yob cov cim thiab tuav khawb tseem pom. Rau kev kho kom zoo nkauj tiav, qhia meej polished lossis tshwj xeeb npaj nto ua ntej anodising.
Q:Vim li cas thiaj muaj roj rau ntawm daim ntawv?
A: Ib qho residual dov lubricant zaj duab xis tseem nyob ntawm qhov chaw. Nws tiv thaiv cov ntawv hauv kev thauj mus los thiab raug tshem tawm los ntawm alkaline tu lossis hnyav so ua ntej vuam, anodising lossis pleev xim.
Q:Yuav tiv thaiv PVC zaj duab xis nyob ntev npaum li cas ntawm daim ntawv?
A: Cov kev taw qhia ib txwm muaj txog li rau lub hlis nyob rau hauv temperate cia, tsawg dua nyob rau hauv qhov kub thiab txias. Cov zaj duab xis yuav tsum tau muab tshem tawm nyob rau hauv tus neeg muag khoom zaj duab xis lub qhov rais hais kom tsis txhob muaj nplaum hloov.
Q:Yam dab tsi yuav tsum tau txiav txim rau ib feem uas yuav hnyav machined?
A: Txiav T651 phaj es tsis yog T6 qhov twg cov khoom ntim loj yuav raug tshem tawm. Lub stretch stress nyem nyob rau hauv T651 txo distortion thiab ua rau ib feem ntawm lub machining sequence.
Q:Puas yog thickness thiab flatness kam rau ua nyob rau hauv lub zeb tiav tsim?
A: Tsis yog. Qhov xwm txheej thiab qhov ntev ntev yog qhov yuav tsum tau ua. Thickness, flatness, camber thiab ntug mob yuav tsum tau teev nyob rau hauv tus kheej, raws li qhov kev tso cai variation nyob ntawm thickness thiab dav.
