Anthu ambiri amaganiza kuti zitsulo zosapanga dzimbiri si dzimbiri, kwenikweni, ndi ngati zitsulo zina zambiri, dzanja kukhudzana kapena kukhudzana ndi mpweya anakhudzidwa ndi chilengedwe adzakhala oxidized dzimbiri, Komanso, zosapanga dzimbiri pamwamba workpiece pambuyo processing makina monga kuwotcherera, kupondaponda, kupindika, kutentha mankhwala ndi njira zina kupanga wosanjikiza wakuda makutidwe ndi okosijeni metamorphic kuumitsa nthawi yowuma, looneka ndi looneka wosanjikiza ndi looneka losanjikiza, Atrrhythmia ndi oxidation. kwa maso wamaliseche ndi pachimake Angle burrs, etc., amene zambiri zovuta kuchotsa ndi makina njira, okhudza sewero la makhalidwe a workpiece zakuthupi palokha. Pofuna kuthetsa mavutowa, anthu amagwiritsa ntchito njira zosiyanasiyana popera ndi kupukuta zitsulo monga zitsulo zosapanga dzimbiri. Pofuna kuthetsa mavutowa, anthu amagwiritsa ntchito njira zosiyanasiyana popera ndi kupukuta zitsulo monga zitsulo zosapanga dzimbiri.

Pamwamba pazitsulo zosapanga dzimbirikumalizag - kupukuta gulu

1.1Kupukuta kwamakina:Makina kupukuta ndi kudula, pulasitiki mapindikidwe a pamwamba zinthu kuchotsa opukutidwa otukukira m'mimba gawo ndi kupeza njira yosalala kupukuta, makamaka ntchito whitetstone Mzere, ubweya gudumu, sandpaper, etc., makamaka ntchito pamanja, mbali zapadera monga pamwamba pa thupi rotary, angagwiritse ntchito zida zothandizira monga tebulo rotary, pamwamba kupukuta zofunika njira angagwiritsidwe ntchito wapamwamba kupukuta njira angagwiritsidwe ntchito. Super finishing polishing ndi kugwiritsa ntchito zida zapadera zogaya, mumadzi opukutira omwe ali ndi abrasive, otsekedwa mwamphamvu pa workpiece kuti apangidwe pamwamba, kuti azitha kuzungulira mofulumira. Kukula kwapamtunda kwa Ra0.008μm kumatha kuchitika pogwiritsa ntchito ukadaulo uwu, womwe ndi wapamwamba kwambiri pakati pa njira zosiyanasiyana zopukutira. Njirayi imagwiritsidwa ntchito nthawi zambiri muzojambula za lens.

1.2Kupukuta kwa Chemical:Kupukuta kwa Chemical ndiko kusungunula gawo laling'ono laling'ono pamwamba pa zinthu zapakatikati mwamankhwala makamaka kuposa gawo la concave, kuti mupeze malo osalala. Ubwino waukulu wa njirayi ndikuti sichifuna zida zovuta, imatha kupukuta chogwirira ntchito ndi mawonekedwe ovuta, ndipo imatha kupukuta zida zambiri panthawi imodzi, ndikuchita bwino kwambiri. Vuto lalikulu la kupukuta kwa mankhwala ndikukonzekera madzi opukutira. Kuuma kwapamwamba komwe kumapezeka ndi kupukuta kwamankhwala nthawi zambiri kumakhala 10μm.

1.3Electrolytic polishing:Mfundo yaikulu ya kupukuta kwa electrolytic ndi yofanana ndi kupukuta kwa mankhwala, ndiko kuti, mwa kusankha kusungunula tinthu tating'ono tating'ono pamwamba pa zinthuzo kuti pamwamba pakhale bwino. Poyerekeza ndi kupukuta kwa mankhwala, zotsatira za cathode reaction zimatha kuthetsedwa ndipo zotsatira zake zimakhala bwino.

The electrochemical kupukuta ndondomeko lagawidwa masitepe awiri: (1) ndi zazikulu kusanja kusungunuka mankhwala diffuses mu electrolyte, roughness geometric wa zinthu pamwamba amachepetsa, ndi Ra> 1μm. (2) Kuwala kwapang'onopang'ono kwa anodic polarization, kuwala kwapamwamba kumawonjezeka, Ra

1.4Akupanga kupukuta:The workpiece imayikidwa mu abrasive kuyimitsidwa ndi kuikidwa pamodzi mu akupanga kumunda, ndi abrasive ndi pansi ndi opukutidwa padziko workpiece ndi kudalira oscillation wa akupanga yoweyula. Akupanga processing macroscopic mphamvu ndi yaing'ono, sichidzachititsa workpiece mapindikidwe, koma tooling kupanga ndi unsembe ndi zovuta. Akupanga processing akhoza pamodzi ndi mankhwala kapena electrochemical njira. Pamaziko a njira dzimbiri ndi electrolysis, akupanga kugwedera umagwiritsidwa ntchito kusonkhezera njira, kuti kusungunuka mankhwala padziko workpiece anapatukana, ndi dzimbiri kapena electrolyte pafupi padziko ndi yunifolomu. Akupanga cavitation mu madzi angathenso ziletsa dzimbiri ndondomeko, amene amathandiza pamwamba kuwala.

1.5Kupukuta kwamadzi: Kupukuta kwamadzimadzi kumadalira kuthamanga kwambiri kwamadzimadzi ndi tinthu tating'ono tomwe timatsuka pamwamba pa workpiece kuti tikwaniritse cholinga cha kupukuta. Njira wamba ndi: abrasive jet processing, madzi ndege processing, hydrodynamic akupera ndi zina zotero. Hydrodynamic akupera imayendetsedwa ndi hydraulic pressure kuti madzi sing'anga kunyamula abrasive particles kuyenda pamwamba pa workpiece pa liwiro lalikulu. Sing'anga imapangidwa makamaka ndi mankhwala apadera (polima-ngati zinthu) ndikuyenda bwino pansi pa kupanikizika kochepa komanso kusakaniza ndi abrasives, omwe angakhale silicon carbide powder.

1.6Kupukuta kwa maginito:Kupukuta kwa maginito ndiko kugwiritsa ntchito maginito abrasives pansi pa mphamvu ya maginito kuti apange burashi yonyezimira kuti ipere ntchitoyo. Njira imeneyi ali ndi ubwino mkulu processing dzuwa, khalidwe labwino, kulamulira mosavuta zinthu processing ndi zinthu zabwino ntchito. Ndi abrasive yoyenera, roughness pamwamba akhoza kufika Ra0.1μm.

Zomwe zimakhudza kupukuta kwa kufa Chifukwa kupukuta kwamakina kumamalizidwa makamaka ndi manja, ukadaulo wopukutira ukadali chifukwa chachikulu chokhudza kupukuta. Kuphatikiza apo, zimagwirizananso ndi zinthu za nkhungu, mawonekedwe apamwamba asanapukutidwe, komanso njira yochizira kutentha. Chitsulo chapamwamba ndichofunika kuti chikhale chabwino chopukutira, ngati kuuma kwachitsulo kumakhala kosagwirizana kapena pali kusiyana kwa makhalidwe, nthawi zambiri kumabweretsa zovuta zopukuta. Zophatikiza zosiyanasiyana ndi pores muzitsulo sizikuthandizira kupukuta.

3.1 Chikoka cha kuuma kosiyana pa ndondomeko yopukuta Kuwonjezeka kwa kuuma kumawonjezera kuvutika kwa kugaya, koma kuuma pambuyo popukuta kumachepa. Chifukwa cha kuchuluka kwa kuuma, nthawi yopukutira yofunikira kuti muchepetse kuuma kumawonjezeka mofanana. Panthawi imodzimodziyo, kuuma kumawonjezeka, ndipo kuthekera kwa kupukuta kwambiri kumachepetsedwa mofanana.

3.2 Chikoka cha workpiece pamwamba pa ndondomeko kupukuta Pophwanya ndondomeko ya zitsulo kudula makina, pamwamba adzakhala kuonongeka ndi kutentha, kupsyinjika mkati kapena zinthu zina, ndi zosayenera kudula magawo zidzakhudza kupukuta. Pamwamba pambuyo pa EDM ndizovuta kwambiri pogaya kuposa pamwamba pambuyo pa makina wamba kapena chithandizo cha kutentha, kotero EDM iyenera kukhala yokonzekera bwino EDM kuvala kumapeto kwa EDM, apo ayi pamwamba pake padzakhala wosanjikiza woonda kwambiri. Ngati njira zowonongeka za EDM sizisankhidwa bwino, kuya kwa kutentha komwe kumakhudzidwa ndi kutentha kumatha kufika pamtunda wa 0.4mm. Kuuma kwa wosanjikiza woonda kwambiri ndi wapamwamba kuposa wa gawo lapansi ndipo kuyenera kuchotsedwa. Choncho, ndi bwino kuwonjezera aukali akupera ndondomeko, kuchotsa kwathunthu kuonongeka pamwamba wosanjikiza, ndi kupanga pafupifupi akhakula pamwamba zitsulo, kupereka maziko abwino kupukuta.

Mankhwala kupukuta kwa zofunika kupukuta si nthawi mkulu, ayenera kutenthetsa ntchito zamakono, ngati angathe kugwiritsa ntchito pamwamba atatu kupukuta musagwiritse ntchito mankhwala kupukuta, chifukwa zotsatira kupukuta mankhwala ndi osauka, mtengo mabuku ndi apamwamba.
