Mu gawo la kupanga zida zamakina zolondola kwambiri, komwe ngakhale kugwedezeka kwa micron-level kungasokoneze khalidwe la kupanga, ntchito ya granite damping yasintha kwambiri. Mayeso aposachedwa a kugwedezeka omwe achitika ndi makampani otsogola opanga zinthu zolondola m'nyumba ndi mabungwe ofufuza zamakampani atsimikizira kuti kukonza bwino mawonekedwe a granite damping kungachepetse kwambiri kugwedezeka kwa makina, motero kukulitsa phindu la zigawo zolondola kwambiri mpaka 15% mpaka 20%. Kupambana kumeneku kukukonzekera kufulumizitsa kukweza kwa makampani opanga makina olondola ku China ndikupereka chithandizo champhamvu chaukadaulo chosinthira zida zamakina apamwamba kwambiri m'nyumba.
Zipangizo zamakina zolondola kwambiri ndi zida zofunika kwambiri popanga zinthu zofunika kwambiri m'magawo monga ma semiconductors, mphamvu zatsopano, ndege ndi magalimoto. Panthawi yokonza makina, kugwedezeka komwe kumachitika ndi chida chamakina, zida zodulira ndi kuyanjana kwa ntchito nthawi zambiri kumabweretsa kukhwima kwa pamwamba, kusinthasintha kwa mawonekedwe komanso kuwonongeka kwa zida, zomwe zimakhudza mwachindunji kuchuluka kwa zinthu zomalizidwa. "Pazochitika zokonza makina zolondola kwambiri zomwe zimafuna kulondola kwa submicron, kuwongolera kugwedezeka ndiye chinthu chofunikira kwambiri," adatero Li Ming, mainjiniya wamkulu ku China Precision Machinery Industry Research Institute. "Maziko a zida zamakina achitsulo opangidwa ndi anthu wamba ali ndi mphamvu zochepa zochepetsera kuuma, zomwe zimapangitsa kuti zikhale zovuta kukwaniritsa zofunikira zolondola kwambiri pakupanga kwamakono."
Poganizira izi, granite pang'onopang'ono yasintha chitsulo chosungunuka kukhala chinthu chomwe chimakonda kwambiri popanga zida zamakina ndi matebulo ogwirira ntchito chifukwa cha mawonekedwe ake abwino kwambiri. Granite yachilengedwe imakhala ndi kuuma kwakukulu, kutentha kochepa komanso kukana kuwonongeka, ndipo kapangidwe kake kapadera kamkati kamapangitsa kuti ikhale yolimba kwambiri - phindu lalikulu lomwe chitsulo chosungunuka sichingafanane nalo. Kuti afufuze mokwanira kuthekera kwa granite damping pakukonza bwino ntchito yopangira makina, gulu lofufuza logwirizana lopangidwa ndi mabizinesi ndi mayunivesite adachita mayeso angapo ofunikira.
Kuyesaku kunachitika pa malo opangira makina a 5-axis ultra-precision okhala ndi maziko a granite, cholinga chake chinali kuyeza momwe chida cha makina chimagwirira ntchito panthawi yodula titanium alloy ndi zida za aluminiyamu zamphamvu kwambiri. Gululo linayamba layesa kuchuluka kwa kugwedezeka ndi kuchuluka kwa maziko achitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo pogwiritsa ntchito njira zomwezo zokonzera, kenako linasintha ndi maziko a granite omwe adachitidwa chithandizo chapadera cha damping optimization ndipo adachita mayeso ofanana. Zotsatira za mayesowa zinasonyeza kuti maziko a granite adachepetsa kuchuluka kwa kugwedezeka kwa chida cha makina ndi 40% mpaka 50% mu 50 Hz mpaka 2000 Hz frequency range, yomwe ndi gulu lalikulu la kugwedezeka komwe kumakhudza kulondola kwa makina.
"Mfundo yaikulu yogwiritsira ntchito bwino granite damping ili m'mbali ziwiri: kusankha zinthu ndi ukadaulo wokonza zinthu pambuyo pake," adatero Wang Tao, mkulu waukadaulo wa Shandong Xinhua Granite Precision Components Co., Ltd., m'modzi mwa omwe adatenga nawo gawo pa mayesowo. "Tinasankha granite ore yokhala ndi mchere wofanana komanso porosity yochepa yamkati, ndipo titadula bwino ndikusamalira kukalamba, tinawonjezeranso magwiridwe antchito a damping kudzera mukusintha pamwamba ndi kapangidwe ka damping. Deta yoyesera kugwedezeka idatsimikizira mokwanira kuti njira izi zimatha kuyamwa bwino ndikuchotsa kugwedezeka kwa makina, kupewa kukhudzidwa ndi mphamvu ya resonance pa khalidwe la makinawo."
Kugwiritsa ntchito bwino kwa ukadaulo wokonzedwa bwino wa granite damping ndi kodabwitsa kwambiri. Kampani yotsogola yopanga zida zamagalimoto ku Shanghai idagwiritsa ntchito ukadaulowu pamakina ake opangira zida zama injini molondola. Pambuyo pa mwezi umodzi woyeserera, kuchuluka kwa ma crankshafts ndi ma camshafts kudakwera kuchoka pa 82% mpaka 98%, ndipo kuuma kwa pamwamba pa zidazo kunachepetsedwa kuchoka pa Ra 0.8 μm kufika pa Ra 0.4 μm, zomwe zidakwaniritsa miyezo yapamwamba yamainjini apamwamba. "Kuchepa kwa zinthu zolakwika sikunangochepetsa ndalama zopangira komanso kwafupikitsa nthawi yopangira, zomwe zabweretsa phindu lalikulu pazachuma ku bizinesi," adatero Zhang Wei, manejala wopanga wa wopanga.
Akatswiri a zamakampani adanenanso kuti kugwiritsa ntchito bwino ukadaulo wowongolera magwiridwe antchito a granite ndi njira yodziwika bwino yolumikizira sayansi ya zinthu ndi makina olondola. Ndi kupita patsogolo kosalekeza kwa ukadaulo monga AI ndi mapasa a digito, kuyesa kugwedezeka ndi kukonza bwino kwa zigawo za granite kudzapitanso patsogolo ku luntha. M'tsogolomu, mabizinesi amatha kusintha magawo ochepetsera madzi a maziko a granite nthawi yeniyeni malinga ndi zida zosiyanasiyana zochepetsera madzi, njira ndi zofunikira zolondola kudzera mu njira zanzeru zowunikira, kukwaniritsa kuwongolera kugwedezeka komwe kumapangidwira payekha komanso molondola.
Bungwe la China Machine Tool Industry Association latulutsa deta yosonyeza kuti kufunikira kwa makina olondola kwambiri okhala ndi zigawo za granite kukukulirakulira ndi 25% pachaka. Kukonza bwino ntchito yochepetsera granite kudzakulitsa kwambiri momwe granite imagwiritsidwira ntchito m'makampani opanga zida zamakina, osati m'malo opangira makina olondola kwambiri komanso m'makina oyezera ogwirizana, zida zopangira laser ndi zida zina zapamwamba. Izi zithandiza makampani opanga zida zamakina ku China kudutsa malire aukadaulo wowongolera molondola ndikuwonjezera mpikisano wake wapadziko lonse lapansi.
"Kuyesa kugwedezeka ndiye maziko owongolera magwiridwe antchito a granite damping, ndipo kukweza phindu la makina ndiye cholinga chachikulu cha luso laukadaulo," adatero Chen Hong, pulofesa ku Sukulu ya Uinjiniya wa Makina ku Tsinghua University. "M'tsogolomu, tipitiliza kukulitsa kafukufuku wokhudza njira yochepetsera kugwedezeka kwa granite, kupanga njira zowongolera bwino komanso njira zoyesera, ndikuthandizira kwambiri pakukula kwapamwamba kwa makampani opanga zinthu zolondola ku China."
Monga chida chofunikira kwambiri pazida zapamwamba kwambiri, granite ikuchita gawo lofunika kwambiri mumakampani opanga makina olondola. Kupita patsogolo kwa ukadaulo wochepetsa magwiridwe antchito, komwe kwatsimikiziridwa ndi mayeso asayansi ogwedezeka, kudzawonjezera mphamvu zatsopano pakukweza makampani opanga zida zamagetsi ku China ndikuthandizira gawo lamakampani opanga zinthu zapamwamba kwambiri mdziko muno kutenga sitepe yolimba kupita kumakampani opanga zinthu zapamwamba padziko lonse lapansi.
