Pamene wina anena mbali zolondola kwambiri, malingaliro ambiri amalumphira molunjika ku kulolerana kolimba pajambula. ± 0.005mm, Ra 0.4, mtundu wa chinthu. Ndiwo pamwamba. Kukambitsirana kwenikweni, komwe kumachitika pansi pa sitolo kapena pakuyimba foni kwa ogulitsa, ndi za chilichonse chomwe chimachitika mozungulira ndi pakati pa manambala amenewo. Ndi za kukhazikika-osati makina okha, koma zakuthupi, ndondomeko, komanso chilengedwe pakupanga zidutswa zikwi khumi. Ndipamene kulondola kwalingaliro kumakumana ndi zenizeni za kukula kwa matenthedwe, kuvala kwa zida, ndi kusagwirizana kosawoneka bwino pagulu la zitsulo zosapanga dzimbiri. Makasitomala ambiri, makamaka omwe angoyamba kumene kufunafuna, amakhazikika pa kulekerera ngati njira yokhayo yomwe ili yabwino. Ndilo lingaliro lolakwika loyamba, ndipo nthawi zambiri lokwera mtengo kwambiri.
Maziko: Zimayamba ndi Zopanda kanthu
Simungathe kuwongolera mwatsatanetsatane gawo ngati geometry yoyambira ndi chinsinsi. Apa ndipamene mgwirizano pakati pa kuponyera ndi Machining umakhala wosakambitsirana. Ndawonapo mapulojekiti akulephera chifukwa malo opangidwa bwino kwambiri adavumbulutsa porosity pansi, cholakwika chomwe chidabadwa m'masabata apitawa. Zoona zigawo zolondola kwambiri, kupanga mapulani ndi ntchito yomaliza. Chochita choyamba ndikupanga mawonekedwe odziwikiratu, owundana, komanso okhazikika pafupi ndi ukonde. Ichi ndichifukwa chake makampani omwe amawongolera kuponya ndi kukonza pansi pa denga limodzi, monga Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., kukhala ndi malire osiyana. Zaka makumi atatu mu zipolopolo ndi kupanga ndalama zikutanthauza kuti amamvetsetsa momwe angapangire zopanda kanthu - maziko - pamakina omwe amatsatira. Ndi za kupanga njira yopangira kuti muchepetse kupsinjika kotsalira ndikupereka makulidwe osasinthika a khoma, kotero gawolo likagunda CNC, silikulimbana ndi mphamvu zamkati zomwe zikuyesera kuzipotoza ngati zinthu zimachotsedwa.
Kusankha kwazinthu apa ndikofunikira, ndipo sikungokhudza zomaliza. Tikulankhula za machinability. Aloyi yopangidwa ndi faifi yogwira ntchito kwambiri imatha kufotokozedwa chifukwa cha kukana kutentha kwake, koma chizolowezi chake chowumitsa ntchito chimatha kupangitsa kubowola kosavuta kukhala chida chosweka ndi geometry yabowo. Kulondola sikuli mu gawo lomaliza; ndi kuthekera kulosera mobwerezabwereza kukwaniritsa gawolo kudzera munjira yonse yodula. Nthawi zina, zokambiranazi zimayenera kubwereranso kwa wopanga makina: Titha kulolera izi, koma taganizirani za aloyi ena omwe ali ndi zinthu zofanana koma makina okhazikika bwino? Itha kupulumutsa 30% pamtengo wa zida ndikuwongolera kusasinthika kwa batch. Ndilo kuitana kothandiza, kongoganizira chabe.
Ndimakumbukira chigawo chimodzi cha valavu ya hydraulic, kachulukidwe kakang'ono mu ductile iron. Zomwezo zinali zolimba pa bore concentricity. Magulu oyambilira ochokera ku gwero lodziwika bwino analipo ponseponse pambuyo popanga makina. Nkhani yake? Micro-shrinkage mu kuponyera komwe sikunkawoneka pamtunda koma kumapanga kuuma kosagwirizana. Wodulayo angapatuke pang'ono, mosayembekezereka. Yankho sanali fancier CNC; inali kukonzanso kachitidwe ka gating ndi riser mu nkhungu yoponyera kuti zitsimikizire kukhazikika kolunjika.

Kuvina kwa Machining: Kukhazikika, Kuwongolera Kutentha, ndi Kuyeza
Chabwino, muli ndi vuto. Tsopano pa siteji aliyense akuwona: malo opangira makina. Apa, kulondola ndikuvina pakati pa kulimba, kukhazikika kwamafuta, ndi metrology. Zimamveka zofunikira, koma mdani wamkulu ndi kutentha. Kutentha kwa spindle, kutentha kwa axis drive, kusinthasintha kwa kutentha kozungulira, ngakhale kutentha komwe kumabwera chifukwa chodzicheka. Kwa gawo lomwe limafunikira kulondola kwamlingo wa micron, kuyendetsa makina mu shopu yomwe ili ndi swing 10 ° C pakati pausiku ndi usana siwoyambitsa. Mukuthamangitsa mchira wanu tsiku lonse. Ndidakhalapo m'malo omwe adayenera kugwiritsa ntchito njira yosavuta yowongolera nyengo pa cell yeniyeni yolondola asanayambe kulankhula za kusunga chakhumi.
Ndiye pali kasamalidwe ka zida. Sikuti amangogwiritsa ntchito zida zapamwamba. Ndi za ndondomeko yolondola yolondolera moyo wa zida ndi kuyembekezera kuwonongeka zisanachoke. Kwa nthawi yayitali, titha kukonza chida chosinthira pang'ono pakapita nthawi, kutengera zomwe zidachitika kale pazidazo. Ndiko kuwongolera mwachangu. The anaika izo ndi kuiwala izo maganizo zimatsimikizira kuti zinyalala. Apa ndipamene zomwe wogwiritsa ntchitoyo amamva - kumva ndi diso - zimakhalabe zofunika, ngakhale ndi mizere yokhazikika. Kumva kusintha pang'ono kwa phokoso lodulidwa, kuona mtundu wa chip kapena mawonekedwe osiyana, kungayambitse kuyang'ana koyambirira ndikulepheretsa gulu lonse kupita cham'mbali.
Ndi muyeso. Mwambi wakale womwe sungathe kuwongolera zomwe suyesa ndi uthenga wabwino. Koma sikuti ndikukhala ndi CMM basi. Ndi za muyeso njira. Kodi mumayang'ana gawo loyamba, lomaliza, ndi chitsanzo chapakati? R&R yanu ndi chiyani? Kodi gawolo ndi lokhazikika kuti ligwirizane ndi kutentha kwa chipinda musanayese? Ndakangana ndi oyang'anira abwino omwe anayeza gawo latsopano pamakina, kutentha mpaka kukhudza, ndikuyiyika ngati kusalolera. Patatha ola limodzi, pa 20 ° C, adawonekera. Ndondomekoyi iyenera kuwerengera izi. Pazinthu zovuta kwambiri, nthawi zina pakufufuza pa chida cha makina ndiyo njira yokhayo yolipirira zosintha zenizeni zenizeni izi.
The Special Alloys Wild Card
Apa ndi pamene zinthu zimakhala zosangalatsa, ndipo nthawi zambiri zimakhala zodula. Zopangidwa ndi Cobalt kapena zitsulo zopangidwa ndi nickel otchulidwa m'malo ovuta kwambiri amabweretsa zovuta zawo pamasewera olondola. Mphamvu zawo ndi kukana kwa dzimbiri zimabwera pamtengo wa kukhala zilombo zenizeni pamakina. Amagwira ntchito molimba mtima, amanyansidwa, ndipo amakonda kusunga kutentha m'mphepete mwake.
Kulondola munkhaniyi kumasintha kuchoka ku kuwongolera kwa geometric ndikuphatikizanso kukhulupirika kwapamtunda. Mutha kuyika gawo kuti likhale labwinobwino, koma ngati mwayambitsa ming'alu yaying'ono kapena kupsinjika kwapang'onopang'ono pamtunda chifukwa cha magawo odulira bwino, gawolo lidzalephera nthawi isanakwane. Kulondola kuli mumkhalidwe wapansi panthaka. Izi zimafunika zida zamtundu wina (zakuthwa, m'mbali zopukutidwa), kukhazikika kolimba kuti mupewe macheza, ndipo nthawi zambiri, kuthamanga kocheperako komwe kumakhala ndi chakudya chambiri - njira yotsutsana ndi akatswiri ambiri opangira zitsulo. Ntchito yozizira imakhala yovuta; sizongozizira, komanso kudzoza ndikuthandizira kuchotsa tchipisi tisanadule ndikuwononga pamwamba.
Tinagwira ntchito yosindikiza turbine seal mu alloy nickel. Mafotokozedwe a flatness ndi parallelism anali olimba kwambiri. Kuyesera koyambirira, pogwiritsa ntchito ma carbide okhazikika, kunapitilirabe kulephera. Gawolo linali lopanda mipanda yopyapyala ndipo mphamvu zodulira, ngakhale zing'onozing'ono, zinkangopangitsa kuti pakhale zotanuka pakumakina kotero kuti zimabwereranso mosagwirizana pambuyo pake. Yankho lake linali njira yamitundu yambiri: roughing, chithandizo cha kutentha chochepetsera nkhawa, kenaka kumaliza, kutsatiridwa ndi chiphaso chomaliza chomaliza pogwiritsa ntchito chopukutira ndi chodula kwambiri, pafupifupi skimming pass, kuyeretsa popanda kuyambitsa kupsinjika kwatsopano. Inali njira yapang'onopang'ono, yokwera mtengo, koma inali njira yokhayo yopezera kulondola kokhazikika. Uwu ndiye nuance yomwe imatayika mu RFQ yosavuta.
Zolephera ndi Maphunziro Amene Amajambula
Simuphunzira kulondola kuchokera ku nkhani zopambana zokha. Mumaphunzira kuchokera ku ngozi, nkhokwe zazing'ono, ndi kubwerera kwa kasitomala. Phunziro limodzi loyambirira, lopweteka linakhudza gulu la ma sensor azitsulo zosapanga dzimbiri. Zinali zigawo zosavuta zotembenuzidwa zokhala ndi kagawo kolondola. Anadutsa kuyendera komaliza mokongola. Patatha mwezi umodzi, kasitomala adanenanso zolephera - mipata idakula pang'ono, zomwe zidapangitsa kuti ma sensor asokonezeke. Tinadabwa kwambiri.
Wolakwa? Kupsyinjika kotsalira kuchokera ku bar yoyambirira ndi makina athu a makina. Tidatembenuza OD ndi ID, kenako tidagaya slot, yomwe idatulutsa zotsekeka zokhoma ndikulola kuti gawolo lisokonezeke pakapita nthawi, chodabwitsa chotchedwa kupsinjika maganizo. Kulondola komwe tidayeza tsiku loyamba kunali chinyengo. Kukonzekera kunali kusintha dongosolo la ntchito ndikuwonjezera kutsika kwapang'onopang'ono kwa kutentha kwapang'onopang'ono pambuyo popanga makina ovuta, kudulidwa komaliza kusanadulidwe. Zinawonjezera sitepe ndi mtengo, koma zidatsimikizira kuti gawolo lidakhazikika. Zimenezo zinasinthiratu mmene timaonera kukonzekera ndondomeko. Sikuti ndi njira yachangu kwambiri kapena yomveka bwino ya makina; ndi za khola kwambiri.
Chinthu china cholephera chofala ndikungoganiza kuti kujambula ndikwabwino. Tinalandirapo chitsanzo cha nyumba ya aluminiyamu yovuta kwambiri yokhala ndi malo ovuta kwambiri. Kulekerera kwapang'onopang'ono kunali kwankhanza koma kotheka mwachidziwitso. Pambuyo polimbana ndi kugunda malo onse panthawi imodzi, tinakhala pansi ndikuyesa msonkhano wonse pafupifupi. Zinapezeka kuti wopanga adakhazikitsa malo osungiramo zambiri m'njira yomwe idayambitsa mkangano - kumenya gulu limodzi la kulolerana kotsimikizika kuphwanya lina. Tinayenera kubwereranso kwa kasitomala ndikukambirana nthawi zina zovuta kuti tikhazikitsenso ma datamu oyambira. Phunziro: kulondola kwenikweni kumafuna mgwirizano ndipo nthawi zina kumatsutsa kapangidwe kake kuti kapangidwe. Mnzako wabwino ngati QSY samangonena mwachimbulimbuli kusindikiza; iwo adzachita nawo kuwunika kwa manufacturability, kufunsa chifukwa chake kumbuyo kwa kulolerana, kuti apeze njira yolimba kwambiri yopitira kumeneko.
Zobweretsedwa Zenizeni: Kuneneratu
Kotero, kodi timagulitsa chiyani tikamalankhula zigawo zolondola kwambiri? Si gawo limodzi lomwe limayezedwa bwino mu labu. Ndi kulosera. Ndi chidaliro kuti gawo la 10,000 mu batch lichita chimodzimodzi ndi loyamba, ndikuti lipitiliza kuchita m'munda kwa nthawi yomwe akufuna. Kudziwikiratu uku ndizomwe zidakambidwa: njira zoyambira zoyendetsedwa (kuponya), makina odziwa bwino za chilengedwe, ukadaulo wowongolera, komanso chidziwitso chakuya.
Apa ndipamene moyo wautali wa wothandizira komanso luso lophatikizika limalipira. Kampani yomwe yadutsa mabizinesi angapo, monga mbiri yazaka 30 ya Mtengo wa QSY, mosalephera wakumana ndi kuthetsa mavutowa pamitundu yambiri yazinthu kuchokera chitsulo chachitsulo ku ma aloyi apadera. Chidziwitso cha bungwe cha zomwe zingasokonekera ndikukhazikika mukukonzekera kwawo. Sangotsatira pulogalamu; iwo akuyembekezera zotsina.
Pamapeto pake, kufunafuna kulondola kwakukulu ndi chilango chokwanira. Zimagwirizanitsa ng'anjo ku benchi yomaliza. Imalemekeza machitidwe azinthu monga momwe makina amagwirira ntchito. Ndipo imamvetsetsa kuti kulolerana kofunika kwambiri kuposa zonse ndikulekerera kusatsimikizika-komwe mumagwira ntchito mwadongosolo kuti muchotse, kusinthasintha kolamuliridwa kamodzi.
