Rau engineers thiab procurement managers nyob rau hauv lub automation kev lag luam, xaiv txoj kev kho deg txheej txheem yog zoo li taug kev ib tug hlau hlau.Xaiv cov txheej txheem tsis ncaj ncees lawm yuav ua rau lub rooj sib txoos jamming ntawm precision Drive ncej vim ntau txheej txheej thickness.
Kev kwv yees ib puag ncig ib puag ncig, kev sib txuas ntawm cov cuab yeej tuaj yeem xeb tsis pub dhau ob peb lub hlis, ua rau tag nrho cov kab ntau lawm raug kaw. Kev nrhiav siab heev ntawm - cov khoom siv kawg tuaj yeem ua rau cov nqi tsim nyog nce ntxiv.
Raws li tus kws tshaj lijPrecision Parts rau SPM tshuab chaw tsim tshuaj paus, peb pom cov neeg siv khoom ntsib teeb meem zoo li no txhua hnub. Qhov kev txiav txim zaum kawg feem ntau poob rau peb tus neeg hnyav hnyav hauv kev lag luam: Dub Oxide, Zinc Plating, thiab Electroless Nickel.
Hauv phau ntawv qhia no, peb yuav soj ntsuam peb cov txheej txheem no, sib piv lawv cov kev tsis sib xws, thiab pab koj txiav txim siab seb qhov twg yog qhov zoo tshaj plaws rau koj Cov Khoom Siv Hluav Taws Xob rau SPM tshuab.
Peb qhov kev kho mob loj steel nto txheej txheem
Ua ntej muab piv cov tsis, cia peb ua ntej qhia meej tias txhua tus txheej txheem ua tau zoo li cas rau saum npoo ntawm cov hlau.
Dub Oxide (Blackening Treatment)
Qhov no yog cov txheej txheem tshuaj hloov pauv txheej txheem. Nws tsis yog txheej txheej ntawm cov ntaub ntawv npog cov hlau nto, tab sis yog cov tshuaj tiv thaiv uas hloov cov hlau nto rau hauv cov hlau nplaum (Fe3O4).
SPM tus nqi tseem ceeb:"Zero tolerance" nto kho. Nws muab qhov yooj yim xeb kuj thiab zoo nkauj dub tsos, tsis hloov qhov luaj li cas ntawm tag nrho cov.
Zinc Plating
Cov txheej txheem electrolysis uas tso ib txheej nyias ntawm zinc rau ntawm cov hlau. Nws ua raws li 'sacrificial anode' - zinc yuav corrode ua ntej steel, yog li tiv thaiv lub substrate.
SPM tus nqi tseem ceeb:tus nqi -zoo "tus neeg saib xyuas". Zoo heev rau cov khoom siv zoo li qub nrog cov peev nyiaj tsawg tab sis xav tau kev tiv thaiv xeb txhim khu kev qha.
Electroless Nickel plating (ENP)
Cov tshuaj tiv thaiv tus kheej catalytic uas tso ib txheej txheej ntawm nickel phosphorus alloy. Cov txheej txheem no tsis xav tau hluav taws xob, yog li yuav tsis muaj "tus dev pob txha" (piv txwv li tam sim no ua rau ntau dhau ntawm lub kaum txheej txheej).
SPM tus nqi tseem ceeb:siab -kev ua tau zoo "shield". Nws zoo kawg nkaus ua ke nrog kev tiv thaiv corrosion, siab hardness, thiab muaj peev xwm los npog cov duab geometric nyuaj.
Kev sib piv ntawm qhov tseem ceeb parameter
Hansheng, nrog rau ntau xyoo ntawm kev paub nyob rau hauv precision mechanical Cheebtsam, muab koj nrog ib tug sib piv ntawm cov tsis tseem ceeb rau peb cov txheej txheem loj ntawm Dub Oxide, Zinc Plating, thiab Electroless Nickel (ENP). Koj tuaj yeem ntsuas qhov txheej txheem Kev Kho Hlau Nto Hlau uas koj xav tau raws li cov lus no.
| Yam ntxwv | Dub Oxide | Zinc Plating | Electroless npib tsib xee (ENP) |
|---|---|---|---|
| Main Function | Aesthetics & Basic Protection | Kev tiv thaiv corrosion | Hnav Resistance & Corrosion Protection |
| Nqi | Tsawg | Tsawg- Nruab nrab | Siab |
| Txheej Thickness | Tsis tsim nyog (< 1 Mm) | 5 - 15 mm (tsis txwv rau qhov no, nyob ntawm qhov kev faib tawm tam sim no) | 5 - 50 hli (zoo ib yam) |
| Kev cuam tshuam rau Dimensions | Tsis muaj (zoo meej tuav kam rau ua) | Nruab nrab (muaj peev xwm tsim ntawm ntug / kaum) | Controllable (ib puag ncig ntawm tag nrho saum npoo) |
| Corrosion Resistance (Salt Spray Test) | Tsawg heev (< 24 - 48 hours*) | Nruab nrab (96 - 120 teev**) | Siab (100 - 1000 teev) |
| Hnav Resistance | Tsawg (tshwj tsis yog oiled) | Tsawg | Siab (txheej hardness 45-50 HRC) |
| Qhov tshwm sim | Matte / Bright Dub | Bright Silver, Xiav los yog daj | Bright Metallic / Stainless hlau tiav |
Ceeb Toom: Kev tiv thaiv xeb muaj peev xwm ntawm Dub Oxide feem ntau nyob ntawm cov roj immersion / wax txheej tom ntej.
Lus Cim: Qhov kev ua tau zoo ntawm Zinc Plating yog nyob ntawm hom kev siv zaj duab xis passivation (Blue White Zinc, Xim Zinc, Dub Zinc).
Kev xaiv qhov zoo tshaj plaws SPM Parts
Txhawm rau ua kom cov ntaub ntawv no siv tau ntau dua, cia peb saib peb yam khoom siv hauv cov khoom siv tsis yog -tus qauv automation thiab txheeb xyuas lawv cov tswv yim kho kom zoo.
Sensor Mounting Bracket
Muaj nuj nqi:Txhim kho lub sensor ntawm lub tshuab thav duab kom tiv taus cov khoom zoo li qub.
Kev txwv:Tus nqi rhiab; Tshaj tawm rau lub Hoobkas huab cua humidity.
Kev xaiv zaum kawg:Zinc Plating (Xiav / Clear Chromate).
Yog vim li cas:Kev hnav tsis kam lossis micrometer qib raug tsis tas yuav tsum muaj ntawm no. Galvanizing muab kev tiv thaiv zoo heev cathodic, tiv thaiv xeb, thiab tsuas yog ib feem me me ntawm npib tsib xee plating, thaum ua kom zoo li cov khoom siv huv si thiab kev tshaj lij.
Precision Tsav Ncej
Muaj nuj nqi:Tig ntawm kev kub ceev hauv cov kabmob thiab xa cov torque.
Kev txwv:nruj kam rau ua (xws li ± 0.005mm); Kev sib txhuam tuaj yeem ua rau hnav thiab tsim kua muag.
Kev xaiv zaum kawg:Electroless Nickel Plating (nruab nrab phosphorus).
Yog vim li cas:Yog tias siv zinc plating, txheej txheej ntawm ob qhov kawg ntawm lub ncej yuav tuab dua li nruab nrab, uas yuav ua rau cov kabmob haum. Dub Oxide tsis hnav -resistant. Tsuas yog Electroless Nickel tuaj yeem muab cov txheej txheem tag nrho uas tuaj yeem tiv thaiv kev sib txhuam thiab kev xeb, thaum tswj xyuas cov duab geometric ntawm lub ncej.
Internal Laser Guide Baffle
Muaj nuj nqi:Thaiv lub teeb stray nyob rau hauv lub optical detection module.
Kev txwv:Tsis tuaj yeem cuam tshuam lub teeb (yuav tsum tau ploj mus); Complex nyob rau hauv cov duab nrog me me threads.
Qhov kawg xaiv yog Dub Oxide.
Yog vim li cas:Lub hom phiaj tseem ceeb yog kev ua haujlwm kho qhov muag (absorption). Tsis tas li ntawd, vim qhov tseeb tias Dub Oxide tsis nce thickness, cov xov precision ntawm lub baffle tseem tuaj yeem raug ntsia hlau zoo kawg nkaus tom qab ua tiav, tsis tas yuav rov tapping.
Tus nqi ntawm ib qho - nres kev tsim khoom
Xaiv hom txheej txheej tsuas yog ib nrab ntawm kev sib ntaus sib tua. Qhov kev sib tw tiag tiag hauv kev tsim khoomMechanical Parts rau SPM tshuablus dag hauv kev ua tiav - tshwj xeeb, kev tswj kev kam rau siab.
Undersize Strategy
Ntawm Hansheng Automation, peb hais txog qhov teeb meem no los ntawm kev sib koom ua keSteel nto kho kev pab:
Kev tshuaj xyuas engineering: Peb tshuaj xyuas koj qhov kev xav tau loj kawg.
Kev them nyiaj ua ntej: Thaum lub sij hawm CNC tig los yog sib tsoo theem, peb txhob txwm tshuab cov khoom rau hauv "undersize" (xws li Ø 9.980mm).
Tswj electroplating: Tswj cov txheej tuab kom raug rau 10 µm.
Qhov kawg tshwm sim: Cov khoom tau ua tiav cov lus qhia zoo meej ntawm Ø 10.000mm tom qab ua tiav.
Qhov no yog qhov zoo ntawm kev ua haujlwm nrog tus neeg muag khoom uas nkag siab ob qho tib siCNC Machining Post Uathiab metallurgy. Peb tsis yog tsuas yog muab cov khoom pov tseg rau hauv lub pas dej, peb xav txog kev kho saum npoo raws li ib feem ntawm precision manufacturing engineering.
Koj yuav tsum xaiv li cas?

Rau brackets, fasteners, thiab lwm yam thav duab (kev tiv thaiv xeb thiab tus nqi tseem ceeb):xaiv Zinc Plating.
Rau siab - tus nqi shafts, li qub, thiab kev hnav tsis yooj yim- cov khoom tiv taus uas yuav tsum tau ua kom tawv thiab precision:xaiv Electroless Nickel.
FAQ
Qhov twg zoo dua rau SPM qhov chaw, Electroless Nickel lossis Hard Chrome?
Qhov no nyob ntawm daim ntawv thov scenario. Hard Chrome muaj hardness siab heev (~ 70 HRC), haum rau linear kev sib txhuam qhov chaw xws li hydraulic rods, tab sis nws yuav muaj ntug teebmeem (tsis sib xws plating). Electroless Nickel muaj qhov nyuaj me ntsis (txog ~ 60 HRC tom qab kev kho cua sov), tab sis nws qhov txiaj ntsig loj tshaj plaws yog qhov sib xws. Rau SPM qhov chaw nrog cov duab tsis yooj yim, qhov sab hauv lossis cov xov, cov tshuaj nickel feem ntau yog qhov kev xaiv zoo dua.
Puas yog tag nrho cov kev kho mob steel ua raws li RoHS cov qauv?
Cov khoom siv niaj hnub feem ntau ua raws, tab sis nws nyob ntawm cov qauv tshwj xeeb. Ib txwm Zinc Plating siv Hexavalent Chromium passivation, uas tsis yog RoHS raws. Niaj hnub no, peb feem ntau siv trivalent chromium passivation txheej txheem, uas ua raws li RoHS ib puag ncig cov qauv. Thov qhia koj qhov kev xav tau ib puag ncig thaum nug.
Kuv puas tuaj yeem pleev xim rau ntawm qhov chaw kho nrog Dub Oxide?
Nws tsis pom zoo kom txau cov xim ncaj qha. Qhov saum npoo ntawm Dub Oxide feem ntau muaj cov roj tiv thaiv xeb, uas tuaj yeem ua rau cov xim tsis ua raws. Yog tias koj npaj yuav ua cov hmoov txheej los yog pleev xim rau yav tom ntej, peb pom zoo kom siv Phosphating hauv qab ua ntej - kho vim tias cov phosphating zaj duab xis muaj adhesion zoo heev.
