M'magawo opikisana kwambiri a mafakitale a magalimoto ndi ndege, mwayi wolakwitsa watha. Kaya kupanga mapanelo opepuka a composite, kukonza zida zovuta za injini, kapena kuchita metrology yowunikira khalidwe, kulondola ndikofunikira kwambiri. Kusintha kwa magetsi, sayansi yapamwamba yazinthu, ndi kukula kwa zigawo zazikulu m'mafakitale onse awiri kumabweretsa kufunikira kwakukulu, kosasinthika pazida zopangira. Pansi pa ma spindles apamwamba, ma laser, ndi manja a robotic, maziko osalankhula—maziko a makina—ndi omwe amatsimikizira malire omaliza a kulondola komwe kungatheke. Apa ndi pomwe granite yolondola yamakampani a magalimoto ndi ndege yakhala chinthu chofunikira kwambiri.
Kukhazikitsidwa kwa njira zamakono zopangira makina odzipangira okha ndi chizindikiro chachikulu cha mizere yamakono yopanga zinthu zamagetsi ndi magalimoto. Makina odzipangira okha awa—kuphatikizapo makina othamanga kwambiri a CNC, makina oyezera ogwirizana (CMMs), ndi nsanja zapadera zopangira zowonjezera—amafunikira zinthu zoyambira zomwe zimatha kupirira mphamvu zazikulu, kuyamwa kugwedezeka, ndikusunga umphumphu wa mawonekedwe pamwamba pa ma envulopu akuluakulu ogwirira ntchito. Kuphatikizana kovuta kumeneku kwa zinthu kumafotokoza kudalira makina apadera a granite m'mafakitale a magalimoto ndi ndege.
Chifukwa Chake Granite Sichingakambiranedwe Pakupanga Molondola Kwambiri
Vuto lalikulu pakupanga zida zazikulu, zodula, komanso zovuta zamafakitale zamagalimoto ndi ndege ndikuwongolera kusakhazikika kwa chilengedwe ndi magwiridwe antchito. Mabedi a makina achitsulo nthawi zambiri amalephera chifukwa amatha kugwedezeka ndi kutentha komanso mphamvu yamagetsi. Granite imathetsa mavutowa ndi mphamvu yake yobadwa nayo:
1. Kusamalira Malo Otentha: Zinthu zamlengalenga, monga masamba a turbine, ndi zida zamagalimoto, monga ma transmission casings, nthawi zambiri zimapangidwa m'malo omwe kutentha kwa mlengalenga kapena kupanga kutentha kwa makina sikungapeweke. Chitsulo ndi chitsulo chopangidwa ndi chitsulo zimakula kwambiri, zomwe zimapangitsa kuti zolakwika za kutentha zigwirizane ndi ma envelopu akuluakulu ogwirira ntchito. Kuchuluka kochepa kwambiri kwa granite yolondola kwambiri (CTE) ya granite yolondola kwambiri yamafakitale a magalimoto ndi ndege kumatsimikizira kuti bedi la makina aukadaulo wodziyimira pawokha limakhalabe lokhazikika. Kusinthasintha kwa kutentha kumeneku ndikofunikira kwambiri kuti tisunge kulekerera kwa micron komwe kumafunikira m'zigawo zomwe zimatha kutalika mamita angapo.
2. Kulamulira Kugwedezeka Kogwira Ntchito Kuti Kukhale Kokhazikika: Kudula, kupukuta, kapena kuyenda mwachangu kwambiri mu metrology yodziyimira payokha kumapanga kugwedezeka komwe kungawononge kutha kwa pamwamba ndikuyambitsa zolakwika zoyezera. Kuchepa kwa granite yachilengedwe mkati mwake kumayamwa bwino mphamvu yamakina iyi. Mwa kutulutsa kugwedezeka kumeneku mwachangu, maziko a granite amaonetsetsa kuti m'mphepete mwa chida chodulira kapena probe ya CMM imakhalabe yokhazikika komanso yokhazikika bwino. Mphamvu yochepetsera kugwedezeka kumeneku ndi yofunika kwambiri kuti tikwaniritse zomaliza zagalasi komanso kulekerera kwa geometric komwe kumafunidwa ndi makampani oyendetsa magalimoto ndi ndege.
3. Kulimba Kwambiri kwa Katundu Wolemera ndi Ma Span Aakulu: Zigawo m'magawo awa, makamaka nkhungu ndi zigawo za airframe, zitha kukhala zazikulu. Maziko a makina a granite amakampani a magalimoto ndi ndege ayenera kupereka kulimba kwakukulu kuti athandizire katundu wolemera popanda kupotoka kulikonse koyezeka. Granite's high Young's modulus imapereka kulimba kofunikira, kuonetsetsa kuti kulumikizana kofunikira kwa njira zolunjika za makina ndi ma axes oyenda kumasungidwa mu envelopu yonse yogwirira ntchito, kuletsa kugwa ndikuwonetsetsa kuti kuya kwa makina kukugwirizana.
Kuphatikiza kwa Uinjiniya pa Magwiridwe Antchito
Kugwiritsa ntchito granite yamakono ndi njira yopangidwa mwaluso kwambiri. Zimaphatikizapo kusankha granite wakuda woyenera, kuchepetsa kupsinjika, kenako kuchita makina olondola kuti agwirizane ndi kapangidwe kake bwino mu dongosolo lodziyimira lokha. Bedi la makina odziyimira lokha sililinso lothandizira; ndi dongosolo logwira ntchito, lopangidwa mwaluso:
-
Makina Olondola Kwambiri: Nyumba za granite zimapangidwa ndi malo omalizidwa bwino, nthawi zambiri zimakhala ndi kulekerera kosalala komwe kumayesedwa mu ma microns kapena kuchepera, zomwe ndizofunikira kwambiri pakuyika njanji zowongolera zolunjika ndi makina onyamula mpweya omwe amagwiritsidwa ntchito popanga makina apamwamba kwambiri.
-
Kuphatikiza Zinthu Zovuta: Zinthu zofunika kwambiri pa ntchito ya makina—kuphatikizapo mabowo omangika a zipangizo zomangira, njira zoziziritsira madzi ndi zingwe, ndi zinthu zoyika zitsulo—zimagwirizanitsidwa bwino. Uinjiniya wapadera uwu umaonetsetsa kuti maziko a granite akugwirizana ndi zofunikira za kinematics ndi zofunikira za ukadaulo wodzipangira wokha.
-
Metrology ndi Kuwongolera Ubwino: Popeza kuti zinthu zomwe zili m'mafakitale a magalimoto ndi ndege zimakhala ndi phindu lalikulu komanso chitetezo, nyumba za granite zimatsimikiziridwa bwino kwambiri. Kuyeza kwa laser interferometer kumatsimikizira kulunjika, kusalala, komanso kukhazikika, kutsimikizira kuti maziko ake ndi maziko ofunikira kuti makinawo akhale olondola.
Mwachidule, popeza magawo onse a magalimoto ndi ndege akukankhira malire a kapangidwe ndi kugwiritsa ntchito zinthu, amafunikira zida zopangira zomwe zili zokhazikika komanso zolondola. Kusankha mwanzeru kwa makina a granite amakampani a magalimoto ndi ndege ndi kudzipereka ku luso loyambira—chisankho chomwe chimalola makina odziyimira pawokha kugwira ntchito bwino kwambiri, kusandutsa mtundu wapamwamba, zinyalala zochepa, komanso kupanga magalimoto otetezeka komanso apamwamba kwambiri komanso ndege.
