ʻO ka hoʻohana ʻana i nā mea hana ana i ka granite precision ma ke kahua ʻoihana.

Granite precision ana mea paahana (square rulers, straightedges, Angle rulers, etc.) pāʻani i ka hana koʻikoʻi ma nā kula kiʻekiʻe he nui ma muli o ko lākou kiʻekiʻe kiʻekiʻe, kiʻekiʻe paʻa a me ka ikaika o ka corrosion.

I ka hana mechanical precision, hoʻohana ʻia ia no ka calibrating i ka pololei o nā alakaʻi alakaʻi a me ka palahalaha o nā papa hana i nā mīkini mīkini CNC, nā kikowaena mīkini a me nā mea hana ʻē aʻe. Me ke koena hoʻonui wela e like me ka haʻahaʻa (4-8) ×10⁻⁶/℃, hiki iā ia ke pale i ka hopena o ka piʻi ʻana o ka mahana i ka wā o ka hana ʻana o nā mea mīkini. I ka nānā ʻana i nā ʻāpana kikoʻī, ʻaʻole e ʻoki ka ʻili haʻahaʻa haʻahaʻa i ka mea hana a kūpaʻa i ka corrosion aila.

He koi koʻikoʻi ka ʻoihana aerospace a me ka pale no ka pololei. Hoʻohana ʻia nā mea ana Granite e hoʻopaʻa i nā kikoʻī o ka ʻenekini mokulele a nānā i nā ʻili o nā pahu missile, a me nā mea ʻē aʻe. He paʻa kemika ikaika a hiki ke hoʻololi i ke kaʻina hana kūikawā o ka hale hana aerospace, e hōʻoiaʻiʻo ana i ka pololei o ka hana ʻana o nā mea nui.

Ma ke kahua o ka uila a me ka hana semiconductor, hoʻohana ʻia nā mea ana granite no ka calibration o nā alakaʻi alakaʻi i nā lako e like me nā mīkini photolithography a me nā mīkini dicing wafer, a me ka nānā ʻana i nā mea hoʻopili chip. ʻO kona hiʻohiʻona ʻaʻohe ua ion metala e pale aku i ka hoʻohaumia ʻana i ka hale hana maʻemaʻe semiconductor, e hōʻoia ana i ka pololei o ka lithography nano-scale a me ka maikaʻi o ka SMT patch soldering.

Hoʻohana nā ʻoihana hoʻāʻo metrology a me nā keʻena noiʻi i nā mea hana ana granite ma ke ʻano he hōʻailona no ka calibrate i nā mea ana metala ʻē aʻe. Loaʻa iā lākou ka paʻa pono lōʻihi lōʻihi, a ʻo ka hoʻololi ʻana ma hope o 10 mau makahiki o ka hoʻohana ʻana he ≤±0.5μm/m. Hoʻohana pinepine ʻia ʻo ia ma ke ʻano he kuhikuhi ana kiʻekiʻe i ka ʻepekema waiwai a me nā hoʻokolohua ʻenekinia optical.

Eia kekahi, ua hoʻohana ʻia nā mea hana granite i ka hana ʻana i nā lāʻau lapaʻau a me nā mea hana optical, e like me ka calibrating ʻana i nā hui o nā robots surgical a me nā kumu o nā brackets telescope astronomical, e hōʻoia i ka loaʻa ʻana o ka sub-millimeter positioning accuracy a me ka aberration-free observation effects. Me ka hana koʻikoʻi, ua lilo nā mea hana ana i ka granite i "pōhaku kihi pololei" o ka hana kiʻekiʻe.
