Mu machitidwe aukadaulo olondola kwambiri, kusankha zinthu si chisankho cha mtengo koma ndi gawo lofunikira pakuchita bwino. Maziko a makina, nsanja za metrology, magawo a semiconductor, ndi kapangidwe ka kuwala zimagwira ntchito pamlingo wololera kuyambira ma micrometer mpaka ma nanometer. Pa masikelo awa, kukhazikika kwa kutentha, kufanana kwa kapangidwe ka microstructure, kugwedezeka kwa kugwedezeka, ndi kukhazikika kwa nthawi yayitali kumakhala zopinga zazikulu zaukadaulo.

Mitundu iwiri yodziwika bwino ya zipangizo imagwiritsidwa ntchito kwambiri mu gawo ili: granite yachilengedwe ndi zoumba zaukadaulo zapamwamba (nthawi zambiri zinthu zopangidwa ndi alumina kapena silicon carbide). Ngakhale zonsezi zimagwiritsidwa ntchito mumachitidwe olondola, chiyambi chawo chakuthupi, kapangidwe kake kakang'ono, ndi makhalidwe awo ogwirira ntchito zimasiyana kwambiri.

Machitidwe a mafakitale ogwira ntchito bwino omwe amapangidwa ndi opanga monga ZHHIMG nthawi zambiri amawunika zinthuzi osati ngati zolowa m'malo, koma ngati mayankho osiyana a ntchito zosiyanasiyana za kapangidwe ka makina.

1. Maziko a Sayansi Yazinthu

Mapeto

Zitsulo za granite ndi za uinjiniya zikuyimira malingaliro awiri osiyana kwambiri pankhani ya uinjiniya wolondola: chimodzi chozikidwa pa kapangidwe ka kristalo kachilengedwe, chinacho chimapangidwa ndi kapangidwe ka microstructure koyendetsedwa.

Granite imachita bwino kwambiri pakunyowetsa, kukhazikika, komanso kulimba kwa kapangidwe kake, pomwe zinthu zadothi zimalamulira kuuma, kutentha, komanso kuwongolera molondola kwa zinthu zazing'ono. Palibe chilichonse mwa zinthuzi chomwe chili chabwino kwambiri padziko lonse lapansi; m'malo mwake, chilichonse chimafotokoza momwe chimagwirira ntchito bwino mkati mwa gawo lake logwirira ntchito.

Mu machitidwe apamwamba kwambiri olondola, tsogolo silikulowa m'malo mwa zinthu koma kuphatikiza zinthu, komwe granite ndi zoumbaumba zimagwirira ntchito limodzi ngati zigawo zothandizirana mu nsanja zovuta za metrology ndi zopangira.
