Munthu akalemba 'machining olondola pafupi ndi ine' mu bar yofufuzira, nthawi zambiri ndimadzifunsa kuti akufuna chiyani. Kodi ndi geography chabe, kapena ndikufunika kokulirapo kwa shopu yomwe angayendetseko, kuyang'ana kapitawo m'maso, ndikukambirana za burr panyumba ya titaniyamu actuator? Mawuwo pawokha ndi osavuta mwachinyengo. Imasonkhanitsa njira yoyembekezeka kwambiri yokhala ndi malo oyambira, ndipo ndipamene kusamvetsetsana koyamba kumakhala nthawi zambiri. Kuyandikira sikutsimikizira kuthekera. Ndawonapo ogula akutenthedwa posankha sitolo yapafupi kwambiri, amangopeza kuti sangathe kugwira ntchito yowona ya 5-axis nthawi imodzi kapena alibe metrology ya kulolerana komwe tikukamba - ganizirani ± 0.0005 pamzere wovuta, osati kungobowola mabowo mu mbale.
Kupyola pa Zip Code: Kutanthauzira Kulondola mu Migwirizano Yeniyeni
Tiyeni tiphwanye 'precision Machining' kuchokera mkati. Si mawu otsatsa omwe timaponya mopepuka. M'dziko lathu ku Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., imayamba ndi katundu. Simungathe kuyika makina olondola ndikuponya molakwika. Ichi ndichifukwa chake zaka zathu makumi atatu mu zipolopolo ndi kupanga ndalama si bizinesi yosiyana; iwo ndi sitepe yoyambira. Ngati mawonekedwe apafupi-ukonde kuchokera ku foundry ali ndi shrinkage yamkati kapena makulidwe a khoma losagwirizana, pulogalamu ya CNC ikulimbana ndi nkhondo yotayika kuchokera pachida choyamba. Chifukwa chake kasitomala akatibweretsera chosindikizira cha pampu yam'madzi mu duplex zosapanga dzimbiri, lingaliro langa loyamba si makinawo. Zili ngati njira yathu yoperekera ikhoza kupereka chopanda kanthu chomwe chimapatsa mbali ya makina mwayi wokwanira kuti igunde kumapeto kwa njirayo.
Mndandanda wazinthu umafotokoza nkhani. Kuponyera chitsulo, zitsulo, zosapanga dzimbiri - zedi. Koma pamene specs ikufuna ma alloys opangidwa ndi cobalt kapena nickel, masewera amasintha. Pafupi ndi ine zimakhala zosafunika kwenikweni ngati sitoloyo siyikumvetsa kuuma kwa ntchito, ilibe mphero zoyenera za ceramic, kapena sizitha kupirira kutentha. Ndimakumbukira ntchito yosindikizira turbine seal ku Inconel 718. Wopikisana naye wamba adayitenga potengera malo. Iwo adawotcha zida, adabweretsa kupsinjika kotsalira, ndipo magawowo adasokoneza pambuyo pakukonza. Wogulayo adatha kutumiza zosoweka zomwe zingapulumutsidwe kwa ife. Kutalikirana kumawatengera mtengo wazinthu zodula komanso kuchedwa kwa milungu ingapo.
Ndiye malangizo anga? Gwiritsani ntchito pafupi ndi ine kuti mupeze ogwirizana nawo, koma awonetseni ndi gawo loyesa. Funsani za kayendetsedwe kawo ka mawonekedwe osavuta koma omveka: dzenje lakuya, laling'ono laling'ono mu 304 lopanda banga. Kodi amatha kugwira mowongoka ndikumaliza mozama 10x m'mimba mwake? Yankho lawo—ndi chitsanzo—adzakuuzani zambiri kuposa pini ya malo awo pamapu.
Mphepete mwa Integration: Pamene Kuponya ndi CNC Kuli Pansi Pa Denga Limodzi
Apa ndipamene chitsanzo cha opanga ophatikizana kwathunthu ngati Mtengo wa QSY kusintha calculus. Ubwino waukulu sikungotengera zinthu, ngakhale kukhala ndi malo opangira makina ndi makina otalikirana ndi mita mazana angapo kumachepetsa nthawi yotsogolera kwambiri. Ndi za mayankho komanso kuyankha. Katswiri wamakina yemwe amakumana ndi malo ovuta poponya amatha kupita kwa manejala woyambira ndikuwunikira. Gulu lothandizira litha kusintha njira yotsekera kapena kuziziritsa kwa batchi yotsatira kutengera zenizeni zamakina, osati zongoyerekeza.
Tidakhala ndi projekiti yamagulu angapo a ma valve mu CF8M osapanga dzimbiri. Makasitomala amafunikira kutsata kwa ASME B16.34, zomwe zikutanthauza kuti NDE yolimba pamasewera komanso kulolerana kolimba pankhope za flange ndikuboola. Chifukwa njira zonse ziwirizi zinali m'nyumba, titha kusindikiza nkhani yoyamba, kuyesa kukakamiza, kupeza vuto la micro-porosity pakona yopsinjika kwambiri, kenako ndikusintha mawonekedwe a choponya. Kubwerezabwerezako kunatenga masiku, osati masabata. Kasitomala akufufuza makina olondola pafupi ndi ine mwina poyamba sangaganize za ulalo woyambira, koma pazigawo zovuta, nthawi zambiri zimakhala kusiyana pakati pa choyimira chomwe chimagwira ntchito ndi chomwe chimangokhala chokwera mtengo.
Choipa chake? Zimafunikira benchi yakuya ya mainjiniya ophunzitsidwa bwino. Okonza makina athu akuyenera kumvetsetsa kuchepetsedwa kwa kulimba. Ndi luso lapadera lomwe silichokera ku malo ogulitsa ntchito pafupi ndi ine lomwe limangopanga makina ogulira mu bar.
Zida, Kukonza, ndi Maola Osawoneka
Aliyense akhoza kugula makina amakono a CNC. Zojambula zenizeni-ndi mtengo wobisika-zili mu njira yogwirira ntchito ndi zida. Pamagulu a nyumba zapampopi, titha kuthera maola 40 tikupanga ndikumanga malo opangira masiteshoni ambiri omwe amatilola kupanga makina 80% azinthu pakukhazikitsa kumodzi. Amenewo ndi maola 40 a nthawi yosagwiritsa ntchito makina opota musanatembenuke. Sitolo yomwe ikupikisana pamitengo yapafupi ndi yotsika ikhoza kudumpha izi, pogwiritsa ntchito vise ndi sitepe, kuyambitsa makonzedwe angapo ndi zolakwika zochulukirapo. Gawolo likhoza kuchitidwa, koma silikhala lolondola.
Ndiye pali mapulogalamu. Njira zamakina othamanga kwambiri a aloyi, mphero ya trochoidal kuti muchepetse kuchuluka kwa zida - apa ndipamene luso la wopanga mapulogalamu limalipira. Izo siziri mu bukhuli. Tidaphunzira izi kudzera m'zida zosweka komanso zidutswa zodulira zisanathe. Tsopano, pazinthu zatsopano monga aloyi ya nickel, tidzachitabe kuyesa kuyesa, kuyimba ma feed ndi kuthamanga ndi dzanja pa ulamuliro, kuyang'ana mtundu wa chip ndikumvetsera kudulidwa. Ndi njira yomwe simungathe kupezerapo kapena kupeza ndi kusaka kosavuta kwamalo.
The Metrology Reality Check
Kulondola kumatanthauzidwa ndi kuyeza, osati cholinga. Sitolo ikhoza kunena kuti ± 0.001 imatha, koma akuyesa ndi chiyani? Kachipangizo kakang'ono ka m'manja ndi kabwino kwa shaft m'mimba mwake, koma ndi yopanda ntchito pa malo enieni a mabowo 12 a bawuti pa PCD kapena mbiri yopindika. Chipinda chathu cha CMM ndichofunika kwambiri monga DMG Mori 5-axis yathu. Ndipo ngakhale pamenepo, kuwongolera chilengedwe kuli kofunika. Timayezera zida zofunika kwambiri za ndege m'mawa, labu itakhazikika kutentha usiku wonse. Ngati mnzanu wakumaloko akuyeza magawo pamalo ogulitsira pafupi ndi khomo lotseguka m'chilimwe, ndiye kuti akukayikira.
Ndikukumbukira kulephera komwe kunandipweteka. Tidapanga zida zoyikamo jekeseni kuchokera kuchitsulo cha H13. Iwo anayeza bwino pa CMM pa 20 ° C. Wogulayo adawayika mu nkhungu yomwe inkayenda pa 90 ° C. Kusiyanasiyana kwa kukula kwa kutentha kunayambitsa kusalinganika molakwika. Sitinaganizire za kutentha kwa ntchito muzowonjezera zathu zololera. Tsopano, pazida zilizonse kapena gawo la kutentha kwambiri, zokambiranazo ndi gawo la ndemanga yoyamba. Ndi phunziro lachindunji, lopweteka lomwe linasintha mndandanda wathu wa DFM.
Kupanga Near Ine Kugwirira Ntchito Inu
Kotero, ngati mukufufuza ntchito makina olondola, gwiritsani ntchito fyuluta ya malo, koma kenaka kukumba mozama. Yang'anani umboni wazopanga zophatikizika ngati gawo lanu likuyamba ngati kuponya kapena kupanga. Yang'anani mbiri yawo yazinthu-funsani maphunziro a zochitika pa alloy yeniyeni yomwe mukufuna. Pemphani ulendo. Sitolo yaukhondo, yokonzedwa bwino yokhala ndi makina amakono, osamalidwa bwino komanso labu yodzipatulira yabwino ndi chizindikiro chabwino. Funsani za CMM yawo yayikulu kwambiri, kulondola kwake kwa volumetric, komanso kuti imasinthidwa kangati.
Kwa kampani ngati yathu, Mtengo wa QSY, mbiri ya zaka 30 si nambala chabe. Zimatanthawuza kuti tapanga masauzande a magawo osiyanasiyana, kuchokera ku tchire losavuta kupita ku zida za reactor, ndipo tapanga chidziwitso chazomwe zingasokonekera. Chidziwitso chimenecho chimaphatikizidwa mukukonzekera ndondomeko. Kuyandikira kwanga kwamakasitomala nthawi zambiri kumapangitsa kuti tizigwirizana mosavuta - amatha kuyendera, kuwona mbali zawo zikugwira ntchito, ndikuwunikanso zaumisiri wamaso ndi maso. Mtengo wosagwirika umenewo nthawi zambiri umaposa kusiyana kwapang'ono pa gawo lililonse kuchokera kwa wogulitsa wakutali, wosadziwika.
Pamapeto pake, kukonza kolondola kwenikweni ndi mgwirizano, osati kugulitsa. Kusaka kuyenera kukhala bwenzi lanzeru lomwe lingakhale lothandiza, osati mwanjira ina. Sitolo yoyenera imafunsa mafunso ambiri monga momwe mumachitira, chifukwa amadziwa kuti mbiri yawo imapangidwa m'gawo lililonse lomwe amatumiza.
