Kodi Zida Zoyezera za Granite Zimasonkhanitsidwa Bwanji Kuti Zikhale Zolondola pa Sub-Micron?

Kwa zida monga mipiringidzo yowongoka ya granite, mabwalo, ndi zofananira - zomangira zoyambira za metrology - msonkhano womaliza ndi pomwe kutsimikizika kotsimikizika kumatsekeredwa. kusonkhanitsa ndi kutsiriza njira zambiri, makamaka moyendetsedwa ndi ukatswiri wa anthu komanso kuwongolera kwachilengedwe. Ntchitoyi imayamba ndi kusankha ZHHIMG Black Granite yathu—yosankhidwa chifukwa cha kachulukidwe kake kopambana (≈ 3100 kg/m³) ndi kukhazikika kwa kutentha—motsatiridwa ndi kukalamba kochepetsa kupsinjika maganizo. Chigawocho chikapangidwa kuti chikhale pafupi ndi ukonde, chimalowa m'malo athu odzipereka, oyendetsedwa ndi kutentha. Apa ndipamene matsenga akugwirana manja amachitikira, opangidwa ndi amisiri athu ammisiri, ambiri omwe ali ndi zaka zopitilira 30. Amisiri alusowa amagwiritsa ntchito njira zololera bwino komanso zopaka, zomwe nthawi zambiri zimatchedwa "kuyenda kwa mzimu wamagetsi" kuti athe kuzindikira zolakwika zazing'ono, kuti achotse mochulukira mpaka kupendekera kofunikira kukwaniritsidwa, kuwonetsetsa kuti malo oyambira akugwirizana ndendende ndi miyezo monga DIN 876 kapena ASME. Chofunika kwambiri, gawo la msonkhano limaphatikizanso kuphatikizika kopanda kupsinjika kwazinthu zilizonse zomwe si za granite, monga zoyika zachitsulo kapena mipata yokhazikika. Zigawo zazitsulozi nthawi zambiri zimamangiriridwa mu granite pogwiritsa ntchito epoxy yapadera, yotsika kwambiri, yomwe imayikidwa pansi pa ulamuliro wokhwima kuti zisayambitse kupanikizika kwamkati komwe kungasokoneze kulondola kwa geometric. Pambuyo pochiritsa epoxy, pamwamba nthawi zambiri amapatsidwa chiphaso chomaliza, chopepuka kuti chiwonetsetse kuti kuyambitsa kwachitsulo sikunapangitse kupotoza kwa mphindi iliyonse mu granite yozungulira. Kuvomereza komaliza kwa chida chosonkhanitsidwa kumadalira muyeso wolondola. Pogwiritsa ntchito zida zapamwamba za metrology monga magawo amagetsi ndi ma autocollimators, chida chomalizidwa cha granite chimawunikidwa mobwerezabwereza motsutsana ndi zida zoyeserera zomwe zili mkati mwamalo okhazikika amphamvu. Mchitidwe wokhwima umenewu—womwe umatsatira mfundo yakuti “Bizinesi yolondola singakhale yovuta kwambiri”—imatitsimikizira kuti chida choyezera cha granite chophatikizidwa sichimangokumana koma nthawi zambiri chimaposa kulekerera kwatchulidwe chisanavomerezedwe ndi kupakidwa kuti chitumizidwe. Kuphatikiza uku kwaukadaulo wotsogola komanso luso losayerekezeka ndizomwe zimatanthawuza kudalirika kwanthawi yayitali kwa zida zolondola za ZHHIMG.
