Akupera Processing
Akupera processing ndi kumaliza Machining (machining anawagawa Machining akhakula, Machining kumaliza, kutentha mankhwala ndi njira zina processing), ndi zochepa processing kuchuluka ndi mwatsatanetsatane mkulu. Amagwiritsidwa ntchito kwambiri m'makampani opanga makina. Kutentha ankachitira ndi kuzimitsidwa mpweya chida zitsulo ndi carburized ndi kuzimitsidwa mbali zitsulo zambiri kuchuluka kwa nthawi zonse anakonza ming'alu - akupera ming'alu - padziko kuti kwenikweni perpendicular malangizo akupera pa akupera. Sizimangokhudza maonekedwe a ziwalozo, komanso zimakhudza mwachindunji ubwino wa ziwalozo.
Amatanthauza kudula kwa workpiece pamwamba ndi mkulu-liwiro kasinthasintha akupera gudumu ndi zina abrasive zida. Kupera kumagwiritsidwa ntchito popanga ma cylindrical amkati ndi akunja, mawonekedwe owoneka bwino ndi ndege zamitundu yosiyanasiyana, komanso mawonekedwe apadera komanso ovuta kupanga monga tchipisi ta Ge Ban, ulusi, magiya ndi ma splines.
Chifukwa cha kuuma kwakukulu kwa njere za abrasive ndi kudzinola kwa zida zowonongeka, kugaya kungagwiritsidwe ntchito pokonza zipangizo zosiyanasiyana, kuphatikizapo zitsulo zolimba, zitsulo zolimba kwambiri, alloy, galasi, ceramics, marble ndi zina zolimba kwambiri. zinthu zopanda zitsulo. Liwiro lopera limatanthawuza kuthamanga kwa liniya la gudumu lopera, lomwe nthawi zambiri limakhala 30 ~ 35 m / s. Ngati ipitilira 45 m / s, imatchedwa kugaya mwachangu.
Kupera nthawi zambiri kumagwiritsidwa ntchito pomaliza ndi kumaliza, ndipo kulondola kumatha kufika IT8 ~ 5 kapena kupitilira apo. Kuuma kwapamtunda nthawi zambiri kumatsikira ku Ra1.25 ~ 0.16 μ m, kugaya molondola mpaka Ra0.16 ~ 0.04 μ m, kugaya kopitilira muyeso mpaka Ra0.04 ~ 0.01 μ m, ndi galasi kupera mpaka Ra0.01 μ m. Mphamvu yeniyeni yakupera (kapena mphamvu yeniyeni yogwiritsira ntchito mphamvu, ndiye kuti, mphamvu zomwe zimagwiritsidwa ntchito podula zida zogwirira ntchito pa voliyumu iliyonse) ndizokulirapo kuposa kudula, komanso kuchotsera zitsulo ndizocheperapo kusiyana ndi kudula.
Choncho, akupera, workpiece kawirikawiri amachotsedwa ndi njira zina kudula kuchotsa Machining chilolezo cha zigawo zikuluzikulu za Jiang Ali, kusiya 0.1 ~ 1mm okha kapena zochepa agawilo gawo. Ndi chitukuko chapamwamba kwambiri akupera, monga zokwawa chakudya akupera ndi mkulu liwiro akupera, mbali akhoza pansi mwachindunji zimene zikusowekapo. Itha kugwiritsidwanso ntchito pakupanga makina ovuta pogaya, monga kuchotsa chothamanga ndi chokwera cha castings, kuwala kwa forgings ndi khungu la ingots zachitsulo.
