M'makonde opanda phokoso komanso olamulidwa ndi nyengo a ma lab amakono a metrology, nkhondo ya chete ikumenyedwa motsutsana ndi mdani wosaoneka: kusakhazikika kwa kukula. Kwa zaka zambiri, mainjiniya ndi asayansi akhala akugwiritsa ntchito granite ngati yolimba kuti apereke maziko enieni a miyeso yathu yolondola kwambiri. Timayang'ana mbale yayikulu ya granite pamwamba kapena maziko a makina ndikuwona chipilala cha bata, chizindikiro chosagwedezeka cha kusalala. Komabe, pamene zofuna za makampani a semiconductor, aerospace, ndi ultra-precision zikutikakamiza kufika pa nanometer sikelo, tiyenera kudzifunsa funso lofunika kwambiri: kodi granite yomwe timadalira ndi yokhazikika monga momwe tikuganizira?
Kafukufuku waposachedwa wa sayansi wokhudza kukula kwa granite—momwe mwalawo “umapumira” ndi kukula ukakhala ndi chinyezi—wabweretsa mafunde m'gulu la akatswiri ofufuza za metrology. Kafukufuku wofunika kwambiri wofalitsidwa mu Journal of the National Conference of Standards Laboratories adawonetsa zenizeni zosangalatsa koma zokhutiritsa: ngakhale granite yapamwamba kwambiri ndi chinthu chachilengedwe chokhala ndi mabowo chomwe chimachitapo kanthu ku chilengedwe chake. Kafukufukuyu akutikumbutsa kuti ngati makina oyezera kutalika kolondola akuyenera kusunga umphumphu wake, zinthu zomwe zimadalira ziyenera kumvedwa pamlingo wa mamolekyulu. Apa ndi pomwe kusiyana pakati pa wogulitsa miyala yosavuta ndi mnzake weniweni pakulondola, monga ZHHIMG®, kumakhala chinthu chofunikira kwambiri pakupambana kwa mafakitale.
Tikamalankhula za kusintha kwa mafakitale olondola kwambiri, kwenikweni tikulankhula za kasamalidwe ka zinthu zosiyanasiyana. Kale, kutentha kunali chifukwa chachikulu cha zolakwika mu muyeso. Tinamanga zipinda zazikulu, zotetezedwa kuti mpweya ukhale pa 20°C nthawi zonse. Koma monga momwe pepala lonena za kukula kwa hygroscopic likusonyezera, chinyezi ndiye mnzawo wosalankhula pa kusuntha kwa dimensional. Kwa opanga ambiri, makamaka omwe amagwiritsa ntchito granite "yamalonda" yotsika kapena, choyipa kwambiri, malo otchipa a marble, kusintha kwa microscopic kumeneku kungayambitse kulephera kwakukulu mu semiconductor wafer alignment kapena CMM calibration. Ku ZHHIMG®, tayembekezera vutoli popitilira zomwe makampani amapereka kuti tipereke zomwe timatcha "ZHHIMG® Black Granite" - chinthu chomwe chimatsutsana ndi zoletsa zomwe zimapezeka mwa miyala yachilengedwe.
Chinsinsi cha kupambana kwathu ndi udindo wathu monga chizindikiro cha dziko lonse lapansi chili mu kuchuluka kwa zinthu zomwe timagwiritsa ntchito komanso momwe timapangira zinthu zomwe timagwiritsa ntchito. Ngakhale mafakitale ambiri ang'onoang'ono amayesa kunyenga msika ndi miyala yotsika mtengo, timatsatira kwambiri mtundu winawake wa granite wakuda womwe uli ndi kuchuluka kwa pafupifupi 3100kg/m³. Kuti timvetse bwino izi, kuchuluka kumeneku kumakhala kwakukulu kwambiri kuposa granite wakuda womwe nthawi zambiri umachokera ku Europe kapena North America. Nchifukwa chiyani izi ndizofunikira kwa wogwiritsa ntchito? Kuchuluka kwambiri kumagwirizana mwachindunji ndi kuchepa kwa ma porosity. Mwalawo ukakhala wokhuthala, pamakhala "malo opanda kanthu" ochepa kuti chinyezi chilowe, motero amachepetsa kwambiri kukula kwa hygroscopic komwe kumavutitsa zinthu zochepa. Poyambira ndi maziko apamwamba a geology, timaonetsetsa kuti "kukula kosawoneka" komwe kwatchulidwa m'mabuku asayansi kwachepetsedwa mwalawo usanalowe m'malo athu.
Komabe, nkhaniyi ndi chiyambi chabe cha nkhaniyi. Kuti tilimbikitse chitukuko cha makampani olondola kwambiri, kampani iyenera kutseka kusiyana pakati pa nthaka ndi uinjiniya wokonzedwa bwino. Likulu lathu ku Jinan, lomwe lili pafupi ndi doko la Qingdao, lili ndi malo opangira zinthu omwe mwina ndi apamwamba kwambiri padziko lonse lapansi. Malo athu okhala ndi malo opitilira masikweya mita 200,000, adapangidwa kuti akwaniritse zosowa zamafakitale amakono. Sitikungopanga ma ruler ang'onoang'ono; tikupanga mafupa a makina apamwamba kwambiri padziko lonse lapansi. Pokhala ndi luso lokonza zinthu chimodzi cholemera mpaka matani 100 ndikufikira kutalika kwa mamita 20, timapereka kukula komwe magawo a ndege ndi CNC amafunikira.
Malingaliro a utsogoleri wathu ndi osavuta: ngati simungathe kuyeza, simungathe kupanga. Kudzipereka kumeneku pa sayansi yoyezera ndichifukwa chake ZHHIMG® yakhala kampani yokhayo m'gawo lathu yomwe ili ndi ziphaso za ISO 9001, ISO 45001, ISO 14001, ndi CE nthawi imodzi. Sitingonena kuti ndi yolondola; timatsimikizira izi pogwiritsa ntchito zida zapamwamba kwambiri padziko lonse lapansi zoyezera. Ma labu athu ali ndi zizindikiro za German Mahr zomwe zili ndi resolution ya $0.5\mu m$, Swiss WYLER electronic levels, ndi British Renishaw laser interferometers. Chida chilichonse chomwe timagwiritsa ntchito chimathandizidwa ndi ziphaso zoyezera kuchokera ku Jinan ndi Shandong Institutes of Metrology, zomwe zimawonetsetsa kuti miyezo ya dziko lonse ikutsatira molondola.
Chomwe chimatisiyanitsadi, komanso zomwe anzathu ku National University of Singapore, Stockholm University, ndi mabungwe osiyanasiyana a dziko lonse lapansi a metrology ku UK, France, ndi US amayamikira, ndi kumvetsetsa kwathu zachilengedwe. Tamanga malo ochitira masewera olimbitsa thupi okhala ndi kutentha ndi chinyezi chokhazikika cha 10,000 square metres omwe ndi odabwitsa kwambiri paukadaulo. Pansi si konkire yokha; ndi konkire wolimba kwambiri wa 1000mm wopangidwa kuti ukhale malo opanda kugwedezeka. Pansi pa slab yayikuluyi pali ngalande zotsutsana ndi kugwedezeka, 500mm mulifupi ndi 2000mm kuya, zomwe zimaonetsetsa kuti phokoso la dziko lakunja—kaya magalimoto kapena zivomerezi—lisafike pazinthu zomwe tikupanga. Ngakhale ma crane pamwamba ndi "mtundu wopanda phokoso", osankhidwa makamaka kuti aletse kugwedezeka kwa mawu kuti kusasokoneze njira yovuta yolumikizirana ndi manja.
Izi zikutifikitsa ku gawo lofunika kwambiri la ZHHIMG®: anthu athu. Mu nthawi yomwe makina athu akuchulukirachulukira, magawo omaliza komanso ofunikira kwambiri olondola amakwaniritsidwabe ndi dzanja la munthu. Akatswiri athu aluso, ambiri omwe ali ndi zaka zoposa 30 zakuchitikira, ali ndi mulingo wa "kukumbukira minofu" womwe umafanana ndi wauzimu. Makasitomala athu nthawi zambiri amawafotokoza ngati "milingo yamagetsi yoyenda." Kudzera mu njira yolumikizirana ndi manja yomwe yasinthidwa kwa zaka makumi ambiri, amatha kumva malo okwera ang'onoang'ono omwe ngakhale masensa ena a digito amavutika kuwazindikira. Akamaliza kuyika mbale ya granite pamwamba, amagwira ntchito pamlingo wa nanometer, "akumva" kuchotsedwa kwa ma microns azinthu kuti akwaniritse kusalala komwe kumagwira ntchito ngati zero-point yopanga zinthu zapamwamba padziko lonse lapansi.
Ukatswiri wa anthu uwu umathandizidwa ndi kutsatira kwambiri miyezo yapadziko lonse lapansi. Gulu lathu silimangodziwa miyezo ya GB yaku China; ndi akatswiri pa miyezo ya DIN yaku Germany (kuphatikiza DIN876 ndi DIN875), miyezo ya American GGGP-463C-78 ndi ASME, JIS yaku Japan, ndi BS817 yaku Britain. Njira yodziwikiratu iyi ya polyglot ndiyo chifukwa chake akuluakulu apadziko lonse lapansi monga GE, Samsung, Apple, Bosch, ndi Rexroth amatidalira ndi mapulojekiti awo ofunikira kwambiri. Kaya ndi maziko a laser ya femtosecond, tebulo la XY la makina a semiconductor lithography, kapena granite air bearing ya woyang'anira wothamanga kwambiri, akatswiri otsogola padziko lonse lapansi amadziwa kuti ZHHIMG® imapereka bata lomwe amafunikira kuti apambane.
Kudzipereka kwathu ku "Osanyenga, Osabisa, Osasokeretsa" sikungokhala mawu a kampani chabe; ndi yankho lachindunji ku mavuto omwe oyang'anira kugula zinthu akukumana nawo mumakampani olondola. Chiyeso cha ogulitsa kuti agwiritse ntchito zipangizo zotsika mtengo komanso zoboola kwambiri ndi chachikulu chifukwa, kwa anthu osaphunzitsidwa, mwala wakuda umodzi umawoneka ngati wina. Koma pansi pa lens ya laser interferometer kapena kupsinjika kwa chipinda chotsukira chokhala ndi chinyezi chambiri, chowonadi chimaonekera pamapeto pake. Posankha ZHHIMG®, makasitomala athu akuyika ndalama mu masomphenya a umphumphu ndi zatsopano. Akusankha mnzanu amene amamvetsetsa sayansi ya kukula kwa hygroscopic ndipo wamanga zomangamanga zapadziko lonse lapansi kuti azitha kuzidziwa bwino.
Pamene tikuyang'ana mtsogolo, ntchito zogwiritsira ntchito zigawo zathu zolondola zikupitirira kukula. Kuyambira pa zipangizo zopezera mabatire atsopano a lithiamu mpaka kuzinthu zovuta za carbon fiber precision beams ndi zigawo za UHPC, kufunika kwa maziko okhazikika komanso odalirika kuli ponseponse. Ndife onyada kukhala bwenzi losalankhula kumbuyo kwa zochitika zofunika kwambiri zaukadaulo padziko lonse lapansi. Tikukupemphani kuti mufufuze zomwe kulondola kwenikweni kungachitire bungwe lanu. Ku ZHHIMG®, tikukhulupirira kuti bizinesi yolondola singakhale yovuta kwambiri, chifukwa m'dziko lolondola kwambiri, palibe malo olakwika.
