Mu mlengalenga wosowa wa makina olondola kwambiri, komwe kulolerana kumayesedwa mu sub-microns ndipo kutentha kumasinthasintha ndi mdani wa khalidwe, kusankha zinthu zomangira sikungoganizira kapangidwe kokha—ndi chinthu chofunikira kwambiri pakuchita bwino. Pamene kupanga kumapitilira malire a fizikisi, makamaka m'magawo monga semiconductor lithography, optical lens grinding, ndi coordinate measuring machines (CMM), muyezo wamakampani wakhazikika kwambiri pa granite. Komabe, "granite" si monolith. Kusankha zigawo zoyenera za granite kumafuna kumvetsetsa bwino za geology, fizikisi, ndi luso lapamwamba lopanga. Nkhaniyi ikutsogolera mainjiniya ndi akatswiri ogula zinthu kudzera muzinthu zofunika kwambiri posankha zigawo zabwino kwambiri za granite kuti zigwiritsidwe ntchito molondola kwambiri.
Maziko a Geological: Si Miyala Yonse Yopangidwa Mofanana
Ulendo wosankha chinthu choyenera umayamba pansi pa nthaka. Pa makina olondola kwambiri, muyezo wa mafakitale ndi granite wakuda, nthawi zambiri umachokera ku mapangidwe enaake a geological omwe amadziwika ndi tirigu wawo wabwino komanso kufanana kwawo. Granite wodziwika kwambiri mwa awa ndi "Jinan Green" kapena "Jinan Black" yomwe imapezeka m'chigawo cha Shandong ku China, dera lomwe lakhala likulu lapadziko lonse lapansi lofukula miyala yabwino kwambiri.
Poyesa ogulitsa omwe angakhalepo, chinthu choyamba chiyenera kukhala kuyera kwa zinthu. Granite yolondola kwambiri iyenera kukhala yopanda mitsempha ya quartz, ming'alu, ndi zinyalala zomwe zingayambitse kulephera kwa kapangidwe kake kapena kuwonongeka kosagwirizana pakapita nthawi. Chida choyenera chili ndi kapangidwe kolimba, kosalala komanso kolimba kwa Mohs pafupifupi 6.5 mpaka 7. Kulimba kumeneku ndikofunikira; kumaonetsetsa kuti gawolo silikukanda ndi kusweka panthawi yogwira ntchito, kusunga umphumphu wake kwa zaka zambiri. Kuphatikiza apo, chidacho chiyenera "kuchepetsedwa kupsinjika" mwachilengedwe. Mosiyana ndi zitsulo zopangidwa ndi chitsulo, zomwe zimafuna kukalamba kopangidwa kuti zichotse kupsinjika kwamkati, granite yachilengedwe yakhala ikukalamba kwa zaka mamiliyoni ambiri, kupereka mulingo wokhazikika womwe zinthu zopangidwa zimavutika kuti zigwirizane nawo.
Kukhazikika kwa Kutentha: Nangula mu Dziko Losinthasintha
M'malo olondola kwambiri, kutentha ndiye gwero lalikulu la zolakwika. Pamene zida zamakina ndi mainjini zikupanga kutentha, kapena pamene kutentha kwa fakitale kumasintha, zipangizo zimakula ndi kufupika. Mwachitsanzo, chitsulo chili ndi coefficient of thermal expansion (CTE) yomwe ingayambitse zolakwika zazikulu patali.
Chigawo choyenera cha granite chimagwira ntchito ngati chothandizira kutentha. Granite wakuda wapamwamba nthawi zambiri amakhala ndi CTE yozungulira
4.6×10−6/∘C, yomwe ndi yotsika kwambiri kuposa ya chitsulo chopangidwa ndi chitsulo kapena chitsulo. Izi zikutanthauza kuti pa kusintha kulikonse kwa kutentha, kapangidwe ka granite kamasintha kukula kwake pang'ono kwambiri kuposa kachitsulo kofanana ndi kachitsulo. Posankha wogulitsa, ndikofunikira kupempha lipoti la katundu wa chinthucho, makamaka kuyang'ana kutsika kwa hygroscopicity (kuyamwa kwa madzi) komanso kuchuluka kwa kutentha kosalekeza. Izi zimatsimikizira kuti makinawo amasunga kulinganiza kwake ngakhale m'malo omwe kuwongolera bwino nyengo kumakhala kovuta.
Magiredi Olondola ndi Kumaliza Pamwamba
Zinthu zopangira zikasankhidwa, zokambiranazo zimasinthira ku luso lokonza. Zigawo za granite nthawi zambiri zimagawidwa m'magulu olondola, nthawi zambiri zimatsatira miyezo monga DIN 876 kapena ASME B89.3.7. Pa makina olondola kwambiri—monga maziko a CMM yapamwamba kapena siteji ya makina opangira laser—magiredi apamwamba kwambiri okha (00 kapena 0 grade) ndi omwe amavomerezedwa.
Kuti mupeze magiredi awa pamafunika kuphatikiza ukadaulo wamakono ndi luso la zaluso. Njira yopangira nthawi zambiri imayamba ndi kudula diamondi yayikulu ndi CNC milling kuti ikwaniritse mawonekedwe osavuta. Komabe, kutha kwa pamwamba ndi kusalala nthawi zambiri kumachitika kudzera mu kulumikiza ndi manja. Apa ndi pomwe luso la wopanga limakhala lofunika kwambiri. Amisiri aluso amagwiritsa ntchito mipiringidzo yolunjika bwino komanso zida zamagetsi kuti akweze ndikupukuta mwalawo, kuchotsa madontho aatali a microscopic kuti akwaniritse kusalala kosakwana 1 micron pa mita imodzi.
Mukasankha mnzanu, yang'anani opanga omwe ali ndi luso la CNC lolimba lopangira roughing komanso malo odzipangira "chipinda choyera" kuti amalize ntchito yomaliza. Fumbi ndi kusinthasintha kwa kutentha panthawi yomaliza yolumikiza zinthu kungawononge kulondola kwa gawolo, kotero malo olamulidwa sangakambiranedwe.
Kusintha ndi Kuphatikiza: Kupitilira Mbale Yathyathyathya
Masiku omwe granite inkagwiritsidwa ntchito ngati tebulo loyang'anira lathyathyathya apita. Makina amakono olondola kwambiri amafunikira zinthu zovuta za 3D—milatho yosuntha, magantries, ndi matebulo ozungulira. Izi zimafuna wopanga wokhoza kukonza zinthu mozama.
Gawo loyenera la granite lidzakhala ndi zitsulo zoyikidwa mkati kuti zikhazikike, mabowo olumikizidwa kuti asonkhanitse, ndi malo olumikizirana a T. Njira yoyika zitsulo izi mu mwalawo ndi luso lokha. Zimaphatikizapo kuboola mabowo enieni, kumangirira zitsulo zosapanga dzimbiri kapena zitsulo zolumikizidwa ndi epoxy yamphamvu kwambiri, ndikuwonetsetsa kuti chomangiracho sichipanga kupsinjika kwamkati komwe kungapotoze mwalawo.
Kuphatikiza apo, opanga apamwamba tsopano amagwiritsa ntchito njira zopangira miyala (granite yopangira) pamodzi ndi miyala yachilengedwe. Izi zimaphatikizapo kusakaniza granite wophwanyika ndi ma epoxy resins kuti apange mawonekedwe ovuta omwe sangatheke kupangidwa kuchokera ku chipika cholimba. Mukayang'ana ogulitsa, ganizirani luso lawo lopereka mayankho "osakanikirana" - kugwiritsa ntchito granite yachilengedwe ngati malo ofunikira komanso kupanga miyala kuti ipange zinthu zambiri, zomwe zimapangitsa kuti mtengo ndi magwiridwe antchito zikhale bwino.
Kufunika kwa Metrology ndi Satifiketi
Mu dziko la kulondola kwambiri, kudalirika kuyenera kutsimikiziridwa. Wogulitsa granite wodalirika sadzangotumiza gawo; adzapereka "chiphaso chobadwa" chokwanira cha gawolo. Zolemba izi ziyenera kukhala ndi lipoti latsatanetsatane lowunikira lopangidwa ndi laser interferometers kapena electronic autocollimators.
Malipoti awa amajambula pamwamba pa granite, kupereka mapu a nsonga ndi zigwa m'dera lonse logwirira ntchito. Pa ntchito zolondola kwambiri, muyenera kufunsa lipoti lomwe limatsimikizira kusalala pamwamba ponseponse, osati pazitsanzo zochepa chabe. Kuphatikiza apo, wogulitsa ayenera kukhala ndi satifiketi ya ISO 9001, kuonetsetsa kuti njira yawo yoyendetsera bwino zinthu ndi yolimba mokwanira kuti ikwaniritse zofunikira zovuta zamakampani opanga ndege, zamankhwala, kapena mafakitale a semiconductor.
Mapeto: Mgwirizano mu Precision
Kusankha zigawo zoyenera za granite si ntchito yogulitsa; ndi mgwirizano. Zimafunika kupeza wogulitsa amene akumvetsa kuti sakungodula miyala yokha, komanso kumanga maziko a kulondola kwa makina anu. Kuyambira ku miyala ya ku Jinan mpaka ku malo ogwirira ntchito zamakono, gawo lililonse la ndondomekoyi limathandizira kuti zida zigwire bwino ntchito.
Mwa kuika patsogolo kuyera kwa zinthu, kukhazikika kwa kutentha, kugawa molondola, ndi njira zovomerezeka zopangira, mainjiniya amatha kuwonetsetsa kuti makina awo olondola kwambiri ali pamaziko olimba kwambiri. Mumakampani omwe amadziwika ndi kulondola, granite yolondola kwambiri imakhalabe maziko a khalidwe labwino.
