Thaum koj saib "Cloud Gate" duab puab hauv Chicago lossis sab nraum qab ntawm lub xov tooj zoo siab -kawg, koj pom qhov xav tsis thoob. Tab sis nyob rau hauv lub ntiaj teb no ntawm precision engineering, daim iav tiav tsis tshua muaj tsuas yog hais txog qhov tsis pom kev.
Rau lub plawv valve implant, daim iav tiav tiv thaiv cov ntshav txhaws. Rau qhov kho qhov muag laser system, nws ua kom pom qhov siab tshaj plaws. Rau cov yas txhaj tshuaj pwm, nws lav qhov seamless tso tawm ntawm ib feem uas tsis muaj cov cim rub.
Raws li cov tuam ntxhab nrog ntau tshaj 10 xyoo ntawm kev paub hauv siab -precision fabrication, peb feem ntau pom engineers kho deg tiav raws li kev xav tom qab. Qhov no yog ib qho yuam kev.Daim iav Polishingyog ib txoj kev tswj xyuas kev tshawb fawb uas tuaj yeem txhais qhov ua tiav lossis tsis ua tiav ntawm cov khoom siv tshuab.
Daim iav Polishing yog dab tsi?
Los ntawm kev pom kev, daim iav polishing yog cov txheej txheem tsim tawm. Nws koom nrog maj mam tshem tawm qhov tsis xws luag ntawm microscopic defects - ncov thiab hav - kom txog rau thaum lub npoo yuav tiaj tus heev nyob rau hauv kev soj ntsuam ze.
Cov khoom siv ib txwm muaj cov cuab yeej pom pom ntawm lawv qhov chaw, thaum Daim iav Polish txo qhov Nto Roughness (Ra) tus nqi qis dua 0.05μm (2 micro-inches).
Cov hauv qab no yog cov ntsiab lus metrological uas koj yuav tsum nkag siab.
Ra (Arithmetic Average Roughness):Qhov taw qhia feem ntau siv. Qhov nruab nrab arithmetic roughness, qhov qis tus nqi, qhov smoother ntawm qhov chaw.
Rz (Mean Roughness Qhov tob):Ntsuas qhov ntsug nrug nruab nrab ntawm lub ncov siab tshaj plaws thiab qhov qis tshaj plaws hauv lub microscopic profile. Nws yog ib qho tseem ceeb rau kev siv sealing.
Gloss Units (GU):Gloss units ntsuas tus nqi ntawm lub teeb pom kev ntawm ib lub kaum ntse ntse.
Ua kom tiav cov txiaj ntsig no yuav tsum muaj cov txheej txheem nruj, suav nrog kev sib tsoo oilstone, lapping, thiab polishing zoo siv pob zeb diamond Compound.

Vim li cas thiaj xaiv Daim iav Polishing
Daim iav polishing muab tus nqi zoo heev -kev ua tau zoo piv, txhim kho kev ua tau zoo thiab kev zoo nkauj ntawm koj cov khoom.
txo hnav
Rau cov tshuab kis tau zoo xws li Planetary Gearbox lossis Harmonic Drives, kev sib txhuam yog qhov tseem ceeb cuam tshuam rau kev ua haujlwm thiab kev ua neej. Los ntawm kev txo tus nqi Ra rau<0.05μm, we minimize the contact area of "micro-asperities", significantly reducing the friction coefficient, heat generation, and wear.
Txhim kho corrosion kuj
Microcracks rau ntawm qhov chaw ntxhib tuaj yeem ntes cov dej noo, ntsev, thiab cov kab mob corrosive. Los ntawm smoothing tawm cov qhov khoob no, Daim iav Polished nto ho txo qhov tshwm sim ntawm corrosion.
Sterility thiab Cleanliness (FDA / Kev Kho Mob)
Rau cov cuab yeej kho mob thiab cov cuab yeej siv tshuaj, kev yooj yim ntawm kev ntxuav yog qhov tseem ceeb heev. Cov kab mob thiab cov kab mob biofilms tuaj yeem loj hlob hauv cov microscopic khawb ntawm qhov chaw ntxhib.
Optical Performance
Rau laser Cheebtsam, sensors, los yog lub zeem muag systems, deg lub teeb tawg yuav tsum raug tshem tawm. Daim iav polishing xyuas kom meej tias lub teeb pom kev raws txoj kev xav tsis muaj diffusing, tswj cov teeb liab kev ncaj ncees.
Yuav ua li cas xaiv tus neeg xa khoom zoo
Cov ntaub ntawv dab tsi muaj rau koj xaiv?
Stainless hlau (304/316L): Kev lag luam tus qauv. Nws muaj cov nyhuv polishing zoo, tab sis tiam ntawm "Orange Peel" yuav tsum zam.
Pwm Hlau (S136 / NAK80): Tshwj xeeb tsim rau polishing siab. Yog tias koj tsim cov yas optical lo ntsiab muag, thov nco ntsoov qhia cov ntaub ntawv hlau no.
Aluminium: mos thiab dag.
Titanium: Vim nws cov viscosity thiab thermal conductivity tsawg, polishing yog qhov nyuaj thiab yuav tsum tau tshwj xeeb abrasives los tiv thaiv qhov kub hnyiab.
Nws puas tuaj yeem polish complex geometric duab?
Internal Channel: Puas yog tus neeg muag khoom muaj peev xwm ntawm Abrasive Flow Machining (AFM)?
Ntse Ntug: Cov neeg ua haujlwm tsis muaj kev paub txog polishing tuaj yeem "tawm" cov ces kaum ntse. Yog tias koj cov khoom yog pwm lossis cov cuab yeej txiav, koj xav tau ib tus neeg muag khoom uas nkag siab txog "nyuaj polishing" thev naus laus zis los tswj hwm kev ncaj ncees.
Yuav ua li cas txog polishing zoo?
Tsis txhob lees txais "zoo" raws li tus qauv zoo. Nug koj tus neeg muag khoom:
Koj puas muaj Surface Roughness Tester?
Koj puas tuaj yeem muab cov ntawv xeem uas qhia txog qhov tseem ceeb ntawm Ra, Rz, thiab Rmax?
Puas yog CMM (coordinate measuring machine) siv los xyuas kom meej tias polishing tsis ua rau geometric deformation ntawm ib feem?
Cov lus qhia:Thaum nug txog tus nqi, thov qhia: "Target Ra yog 0.02μm. Thov paub meej tias koj tuaj yeem tswj tau qhov ntev ntev ntawm ± 0.005mm tom qab polishing."
Yog tias koj tab tom nrhiav ib pab neeg tshwj xeeb hauv kev ntsuas qhov zoo ntawm qhov chaw nrog qhov tseeb, thov saib peb Daim iav Polishing Peev Xwm thiab xa peb cov duab kos rau kev ntsuas qhov ua tau.
FAQ
Q: Koj puas tuaj yeem ua Daim iav Polish ntawm Aluminium (aluminium alloy)?
A: Yog, tab sis txhuas yog feem ntau yuav khawb dua li hlau. Peb pom zoo kom siv cov qib aluminium nyuaj (xws li 7075) thiab tejzaum nws ua cov pob tshab anodization tom qab polishing los tiv thaiv cov luster, txawm hais tias anodization tuaj yeem txo qis qhov kev xav ntawm kev xav.
Q: Qhov txawv ntawm SPI-A1 thiab SPI-A2 qauv yog dab tsi?
A: Cov no yog cov qauv hauv kev lag luam pwm. SPI-A1 xav tau Qib #3 pob zeb diamond polishing (kwv yees Ra 0.012μm), uas yog tus qauv siab tshaj plaws. SPI-A2 tso cai rau siv me ntsis coarser pob zeb diamond muab tshuaj txhuam (Qib #6), nrog me ntsis qis dua tab sis tus nqi ntau dua - zoo.
Q: Daim iav polishing puas tuaj yeem tshem tawm cov cuab yeej sib sib zog nqus?
A: Polishing tsis yog tsim los tshem tawm cov khoom loj, tab sis ua kom zoo dua qhov chaw. Yog tias muaj cov cuab yeej sib sib zog nqus, lawv yuav tsum tau muab tshem tawm los ntawm kev sib tsoo los yog kev ua haujlwm zoo ua ntej polishing theem pib. Peb siv siab -precision Hlau EDM lossis CNC Sib Tsoo los npaj lub hauv paus zoo meej.
Q: Daim iav Polishing puas muaj qhov txiav txim yam tsawg kawg nkaus (MOQ)?
A: Vim muaj kev koom tes ntawm kev teeb tsa, chav tsev nqi ntawm ib tus qauv yog qhov siab. Txawm li cas los xij, peb kuj txhawb Rapid Prototyping thiab me me rau nruab nrab -sized batch ntau lawm.
