Txoj kev kho deg ntawm CNC machined qhov chaw

Hauv kev lag luam prototyping ceev ceev, ntau yam kev kho saum npoo yog siv. Kev kho deg yog hais txog kev tsim cov txheej txheem nrog ib lossis ntau qhov tshwj xeeb ntawm cov khoom siv los ntawm kev siv lub cev lossis tshuaj. Kev kho deg tuaj yeem txhim kho qhov tsos, hnav tsis kam, corrosion kuj, hardness, lub zog thiab lwm yam ntxwv ntawm cov khoom.

1. Default machined nto

Machined nto yog ib qho kev kho saum npoo. Qhov saum npoo ntawm qhov tsim tom qab CNC machining tiav yuav muaj cov kab ua tiav, thiab tus nqi nto roughness yog Ra0.2-Ra3.2. Feem ntau muaj cov kev kho deg xws li deburring thiab ntse ntug tshem tawm. Qhov saum npoo no haum rau txhua yam khoom siv.

2. Sandblasting

Cov txheej txheem ntawm kev ntxuav thiab roughening nto ntawm lub substrate siv cov kev cuam tshuam ntawm high-ceev xuab zeb txaus tso cai rau saum npoo ntawm lub workpiece kom tau ib tug tej yam kev mob ntawm cleanliness thiab txawv roughness, yog li kev txhim kho cov neeg kho tshuab zog ntawm lub workpiece nto, yog li txhim kho qhov qaug zog tsis kam ntawm lub workpiece thiab ua rau lub adhesion ntawm nws thiab cov txheej txheem ntawm coatings thiab coatings rau qib thiab durability. kho kom zoo nkauj ntawm txheej.

2. Polishing

Cov txheej txheem electrochemical cleans steel Cheebtsam los ntawm kev ua cov hlau shinier kom txo tau corrosion thiab txhim kho tsos. Tshem tawm kwv yees li 0.0001 "-0.0025" ntawm cov hlau. Ua raws li ASTM B912-02.

4. Ordinary anodizing

Txhawm rau kov yeej qhov tsis xws ntawm aluminium alloy nto hardness thiab hnav tsis kam, nthuav dav ntawm daim ntawv thov, thiab txuas ntxiv lub neej kev pab cuam, anodizing tshuab yog siv dav thiab ua tiav. Ntshiab, dub, liab thiab kub yog cov xim ntau tshaj plaws, feem ntau txuam nrog txhuas. (Ceeb Toom: Yuav muaj qee yam xim txawv ntawm cov xim tiag tiag tom qab anodization thiab xim hauv daim duab.)

5. nyuaj anodized

Lub thickness ntawm hard oxidation yog tuab dua li ntawm cov oxidation zoo tib yam. Feem ntau, cov tuab ntawm cov yeeb yaj kiab oxide zoo tib yam yog 8-12UM, thiab cov tuab ntawm cov oxide zaj duab xis yog feem ntau 40-70UM. Hardness: Ordinary oxidation feem ntau HV250--350

Hard oxidation feem ntau yog HV350--550. Kev rwb thaiv tsev nce ntxiv, nce hnav tsis kam, nce corrosion kuj, thiab lwm yam. Tab sis tus nqi kuj tseem yuav nce ntxiv.

6. Tshuaj pleev xim rau

Ib txheej siv rau saum npoo ntawm cov hlau workpieces los kho kom zoo nkauj thiab tiv thaiv cov hlau nto. Nws yog tshwj xeeb tshaj yog haum rau hlau-dense cov ntaub ntawv xws li txhuas, alloys, thiab stainless hlau. Nws yog dav siv los ua electroplating varnish rau ntawm qhov chaw ntawm cov khoom siv electroplated xws li teeb, khoom siv hauv tsev, hlau nto, thiab cov khoom siv hlau. Nws tseem tuaj yeem siv los ua cov xim pleev xim rau tsheb, maus taus accessories, roj tso tsheb hlau luam, thiab lwm yam.

7.Matt

Siv cov xuab zeb zoo abrasive los txhuam rau ntawm qhov chaw ntawm cov khoom los tsim cov kev xav tsis thoob thiab cov teebmeem tsis zoo. Cov nplej sib txawv tau ua raws li sab nraub qaum ntawm cov ntawv hauv ob sab phlu lossis cov duab los qhia, thiab cov nplej sib txawv tuaj yeem txawv raws li lawv qhov loj: qhov loj ntawm cov nplej loj, qhov zoo dua cov nplej abrasive, thiab cov nyhuv zoo dua.

8.Passivation

Ib txoj hauv kev los hloov cov hlau saum npoo mus rau hauv lub xeev uas tsis tshua muaj kev cuam tshuam rau oxidation thiab ua rau qeeb ntawm corrosion ntawm cov hlau.

9. Galvanized

Galvanized zinc txheej ntawm cov hlau lossis hlau los tiv thaiv xeb. Txoj kev siv feem ntau yog kub-dip galvanized, immersing qhov chaw rau hauv lub melting kub zinc zawj.
