Mu dziko la kupanga zinthu molondola kwambiri, granite yakhala chinthu chofunikira kwambiri pa maziko a makina, mapulatifomu oyesera, ndi zida zosonkhanitsira. Kukhazikika kwake kodabwitsa, kuyamwa kwake ndi kugwedezeka, komanso kukana kutentha kumapangitsa kuti ikhale yofunika kwambiri pazida za semiconductor, makina owunikira owonera, makina oyezera ogwirizana, ndi zida zina zolondola kwambiri. Komabe, ngakhale kuti ili ndi ubwino wambiri, funso limodzi nthawi zambiri limabuka pakati pa mainjiniya ndi opanga: kodi mapulatifomu olondola a granite ali ndi kupsinjika kwamkati, ndipo izi zingachotsedwe bwanji bwino kuti zitsimikizire kulondola kwa nthawi yayitali?
Granite, monga zinthu zina zachilengedwe, imapangidwa kwa zaka mamiliyoni ambiri pansi pa kupsinjika kwakukulu kwa geological. Ngakhale izi zimaipatsa kukhuthala kwakukulu ndi kukhazikika kwa kapangidwe kake, sizitsimikizira kufanana kwathunthu. Kusiyanasiyana kwa kapangidwe ka mchere, ming'alu yachilengedwe, ndi kusiyana kwa kuzizira ndi mapangidwe kungayambitse kupsinjika kwamkati mwa miyala yaying'ono. Pa nsanja yolondola ya granite, ngakhale kupsinjika kochepa kwamkati kumatha kuwonekera ngati kupindika, ming'alu yaying'ono, kapena kusintha pang'ono kwa mawonekedwe pakapita nthawi, zomwe sizivomerezeka pakugwiritsa ntchito zomwe zimafuna kulondola kwa nanometer.
Apa ndi pomwe njira zamakono zopangira zinthu komanso kuwongolera bwino khalidwe zimayambira. Makampani monga ZHHIMG®, odziwika padziko lonse lapansi chifukwa cha zigawo za granite zolondola, amagwiritsa ntchito njira zambiri zomwe zimapangidwa kuti atulutse kupsinjika kwamkati pulatifomu isanatuluke mufakitale. Njirayi imayamba ndi kusankha mosamala ZHHIMG® Black Granite yaiwisi, yosankhidwa chifukwa cha kuchuluka kwake kwakukulu (~3100 kg/m³) komanso kukhazikika kwabwino poyerekeza ndi granite yakuda ya ku Europe ndi America. Kugwiritsa ntchito zipangizo zosalimba, monga marble wotsika, kungayambitse kusinthasintha kwakukulu ndi kupsinjika kwamkati, zomwe zimawononga magwiridwe antchito anthawi yayitali. ZHHIMG imatsutsa mwamphamvu machitidwe otere, kuonetsetsa kuti granite yapamwamba kwambiri yokha ndi yomwe ikugwiritsidwa ntchito.
Zinthuzo zikasankhidwa, ma granite akuluakulu amadulidwa movutikira komanso nthawi yokalamba. Gawoli limalola granite kuti ichotse mavuto ena omwe amabwera chifukwa chochotsa ndi kusamalira. Pambuyo pokonza zinthu movutikira, ma granite amalowa m'malo olamulidwa bwino komwe kutentha ndi chinyezi zimayendetsedwa bwino. Mu malo ochitira masewera olimbitsa thupi a ZHHIMG okhala ndi malo okwana 10,000 m², pansi pake pamapangidwa ndi konkriti yolimba kwambiri yokhala ndi ngalande zozama zodzipatula, zomwe zimapangitsa kuti pasakhale kusokoneza kwakunja panthawi yochepetsa kupsinjika. Apa, granite imafanana pang'onopang'ono, zomwe zimapangitsa kuti kupsinjika kwamkati kutuluke mofanana mumwala wonse.
Gawo lotsatira lofunika kwambiri ndi kupukuta ndi kulumikiza molondola. Akatswiri odziwa bwino ntchito, ambiri omwe ali ndi zaka zambiri akugwira ntchito mwakhama, amachotsa pang'onopang'ono zigawo za pamwamba pamene akuyesa mosalekeza kusalala ndi kulunjika. Kuchotsa mosamala zinthu kumeneku sikuti kumangopanga nsanjayo kuti ikhale yofanana ndi miyeso yomwe mukufuna komanso kumathandiza kuchotsa zotsalira zomwe zatsala pafupi ndi pamwamba. Mwa kuphatikiza kupukuta kwa CNC kolondola kwambiri ndi kulumikiza ndi manja, ZHHIMG imaonetsetsa kuti mbale iliyonse ya granite pamwamba kapena maziko a makina amafika pamlingo wa nanometer ndipo amakhalabe olimba pakapita nthawi.
Metrology imagwira ntchito yofunika kwambiri pozindikira ndikuwongolera kupsinjika kwamkati. Zipangizo zoyezera zapamwamba—kuphatikizapo Renishaw laser interferometers, WYLER electronic levels, Mitutoyo indicators, ndi high-precision roughness testers—zimagwiritsidwa ntchito nthawi yonse yopanga. Zipangizozi zimazindikira ngakhale kusintha pang'ono komwe kumachitika chifukwa cha kupsinjika kwamkati kapena kuchotsa zinthu mosagwirizana, zomwe zimathandiza akatswiri kupanga zosintha pang'onopang'ono. Muyeso uliwonse umatsatiridwa ndi mabungwe apadziko lonse lapansi a metrology, zomwe zimapatsa makasitomala chidaliro kuti nsanja zawo za granite zimakwaniritsa miyezo yoyenera.
Kufunika kochotsa kupsinjika kwamkati kumapitirira kugwira ntchito mwachangu. Pakusonkhanitsa molondola, mapulatifomu onyamula mpweya, ndi zida zoyezera, ngakhale kupotoza kwa ma micron kungakhudze kulinganiza kwa machitidwe a kuwala, kulondola kwa makina oyezera ogwirizana, kapena kubwerezabwereza kwa njira zopangira mwachangu kwambiri. Maziko a granite opanda kupsinjika amatsimikizira osati kukhazikika kwa magawo okha komanso kudalirika kwa nthawi yayitali, kuchepetsa nthawi yogwira ntchito ndikusunga mtundu wokhazikika wopanga m'malo ofunikira kwambiri amafakitale.
Kugwirizana ndi mayunivesite ndi mabungwe a metrology padziko lonse lapansi kumawonjezera luso la ZHHIMG lomvetsetsa ndikusamalira kupsinjika kwamkati. Kugwirizana ndi kafukufuku ndi mabungwe monga Nanyang Technological University, Stockholm University, mabungwe a metrology aku Britain ndi France, ndi National Institute of Standards and Technology (NIST) ku United States kumalola kusintha kosalekeza kwa njira zoyezera ndi njira zochepetsera kupsinjika. Kuphatikiza kumeneku kwa chidziwitso chamaphunziro ndi machitidwe amafakitale kumayika ZHHIMG ngati mtsogoleri pakupanga granite molondola kwambiri.
Masiku ano, kuthetsa kupsinjika kwamkati mwansanja za granitesi chinthu chapamwamba koma chofunikira. Opanga zida za semiconductor, omanga makina a laser olondola, ndi makampani a metrology padziko lonse lapansi amadalira maziko a granite ndimbale zapamwambazomwe zimakhalabe zosalala, zokhazikika, komanso zodalirika kwa zaka zambiri. Ndi kuphatikiza kwa zipangizo zopangira zapamwamba, kukonza kwapamwamba, akatswiri odziwa bwino ntchito, komanso kuyeza kwa zinthu mozama, ZHHIMG imaonetsetsa kuti kupsinjika kwamkati kumachepetsedwa ndikuwongoleredwa, kupereka nsanja zomwe zimakhazikitsa muyezo wapadziko lonse lapansi wa magwiridwe antchito olondola kwambiri.
Pomaliza, ngakhale granite yonse yachilengedwe ingakhale ndi kupsinjika kwamkati poyamba, kusankha mosamala zinthu, kukalamba kolamulidwa, kukonza molondola, kuluka ndi manja, ndi kuwerengera kosalekeza kumathandiza opanga kuthetsa kukhudzidwa kwake. Kwa mafakitale omwe kulondola sikungatheke kukambirana, nsanja ya granite yolondola yopanda kupsinjika ndiyo maziko, ndipo ZHHIMG ikadali patsogolo popereka mayankho omwe amaphatikiza mphamvu zachilengedwe ndi ungwiro wopangidwa.
