Njira zochizira pamwamba pazigawo zamakina za CNC

M'makampani opanga ma prototyping othamanga, njira zosiyanasiyana zamankhwala zimagwiritsidwa ntchito. Chithandizo chapamwamba chimatanthawuza kupangidwa kwa wosanjikiza wokhala ndi chinthu chimodzi kapena zingapo zapadera pamwamba pa chinthu kudzera munjira zakuthupi kapena zamankhwala. Chithandizo chapamwamba chimatha kukonza mawonekedwe, kukana kuvala, kukana dzimbiri, kuuma, mphamvu ndi zina zazinthu.

1. Kufikira makina pamwamba

Malo opangidwa ndi makina ndi mankhwala omwe amagwiritsidwa ntchito kawirikawiri. Pamwamba pa gawo lomwe linapangidwa pambuyo poti makina a CNC atsirizidwa adzakhala ndi mizere yomveka bwino, ndipo mtengo wa roughness pamwamba ndi Ra0.2-Ra3.2. Nthawi zambiri pamakhala chithandizo chapamwamba monga kubweza ndi kuchotsa m'mphepete. Pamwambapa ndi oyenera zipangizo zonse.

2. Kuphulika kwa mchenga

The ndondomeko kuyeretsa ndi roughening pamwamba pa gawo lapansi pogwiritsa ntchito mphamvu ya mkulu-liwiro otaya mchenga amalola pamwamba pa workpiece kupeza mlingo wina wa ukhondo ndi roughness osiyana, potero kuwongolera mawotchi zimatha pamwamba pa workpiece, potero kuwongolera kutopa kukana kwa workpiece ndi kuonjezera adhesion pakati pa izo ndi ❖ kuyanika kumawonjezera kulimba kwa filimu ndi kukongoletsa kumawonjezera kulimba kwa filimu ndi kukongoletsa kwake.

2. Kupukutira

Dongosolo la electrochemical limatsuka zitsulo popanga chitsulo chowala kuti chichepetse dzimbiri ndikuwongolera mawonekedwe. Imachotsa pafupifupi 0.0001"-0.0025" yachitsulo. Zogwirizana ndi ASTM B912-02.

4. Anodizing wamba

Pofuna kuthana ndi zolakwika za aluminiyumu aloyi kuuma pamwamba ndi kukana kuvala, kukulitsa kuchuluka kwa ntchito, ndikuwonjezera moyo wautumiki, ukadaulo wa anodizing ndi womwe umagwiritsidwa ntchito kwambiri komanso wopambana. Zowoneka bwino, zakuda, zofiira ndi golidi ndizo mitundu yodziwika bwino, yomwe nthawi zambiri imagwirizanitsidwa ndi aluminiyumu. (Dziwani: Padzakhala kusiyana pakati pa mtundu weniweni pambuyo pa anodization ndi mtundu womwe uli pachithunzichi.)

5. Ovuta anodized

Kukhuthala kwa oxidation yolimba ndi yokhuthala kuposa ya okosijeni wamba. Nthawi zambiri, makulidwe a filimu ya oxide wamba ndi 8-12UM, ndipo makulidwe a filimu yolimba ya oxide nthawi zambiri amakhala 40-70UM. Kuuma: Oxidation wamba nthawi zambiri HV250--350

Oxidation yolimba nthawi zambiri imakhala HV350--550. Kuwonjezeka kwa kutsekemera, kuwonjezeka kwa kukana kuvala, kuwonjezeka kwa dzimbiri, etc. Koma mtengo udzawonjezekanso.

6. Utsi penti

Chophimba chomwe chimagwiritsidwa ntchito pamwamba pazitsulo zopangira zitsulo kukongoletsa ndi kuteteza pamwamba pazitsulo. Ndiwoyenera makamaka kuzinthu zowuma zitsulo monga aluminium, alloys, ndi chitsulo chosapanga dzimbiri. Amagwiritsidwa ntchito kwambiri ngati ma varnish a electroplating pazida zamagetsi zamagetsi zamagetsi monga nyali, zida zapakhomo, zachitsulo, ndi zaluso zachitsulo. Itha kugwiritsidwanso ntchito ngati utoto wodzitetezera wamagalimoto, zida za njinga zamoto, matanki amafuta, ndi zina.

7. Matte

Gwiritsani ntchito tinthu tating'onoting'ono ta mchenga topaka pamwamba pa zinthuzo kuti tipange mawonekedwe owoneka bwino komanso osatengera mawonekedwe. Mbewu zonyezimira zosiyanasiyana zimamatiridwa kumbuyo kwa pepala lokhalamo kapena makatoni, ndipo makulidwe osiyanasiyana ambewu amatha kuzindikirika molingana ndi kukula kwake: kukula kwake kwambewu, kumapangitsa kuti mbewu za abrasive ziwoneke bwino, komanso momwe zimakhalira bwino.

8.Kukonda

Njira yosinthira chitsulo kukhala malo osakhudzidwa kwambiri ndi okosijeni ndikuchepetsa kuwononga kwachitsulo.

9.Magalati

Kupaka zinki pazitsulo kapena chitsulo kuti musachite dzimbiri. Ambiri ntchito njira ndi otentha - kuviika kanasonkhezereka, kumiza mbali mu kusungunuka otentha zinki poyambira.
