He aha ka ʻāpana granite kikoʻī?

Hoʻohana ʻia nā ʻāpana granite kikoʻī i nā ʻano hana ʻoihana like ʻole, kahi e pono ai ka pololei a me ke kūpaʻa kiʻekiʻe. Hana ʻia kēia mau ʻāpana mai ka granite kiʻekiʻe i koho pono ʻia a hana ʻia e hōʻoia i nā waiwai kūlike a me ke kūpaʻa maikaʻi loa.

He mōʻaukala lōʻihi ka hoʻohana ʻana i ka granite ma ke ʻano he mea no nā ʻāpana kikoʻī, mai ka wā kahiko o ʻAigupita i hoʻohana i ka granite i ke kūkulu ʻana i kā lākou mau pyramids. I kēia lā, hoʻohana ʻia nā ʻāpana granite kikoʻī i nā ʻoihana mai ka ʻenekinia kikoʻī a me ka metrology a hiki i ka optics a me ka hana semiconductor.

ʻO nā ʻano koʻikoʻi o ka granite e hoʻolilo iā ia i mea kūpono no nā ʻāpana kikoʻī, ʻo ia kona nui kiʻekiʻe, ka porosity haʻahaʻa, ka paʻakikī kiʻekiʻe, a me ke kūpaʻa wela maikaʻi loa. He mea nui kēia mau waiwai no ka hoʻokō ʻana i nā pae kiʻekiʻe o ka pololei a me ke kūpaʻa e pono ai i nā noi ʻoihana he nui.

ʻO kekahi o nā hoʻohana maʻamau o nā ʻāpana granite precision ʻo ia ke kūkulu ʻana i nā lako ana precision e like me nā mīkini ana coordinate (CMM). Hāʻawi ke kumu granite o kahi CMM i kahi ʻili kuhikuhi maikaʻi loa no ke ana pololei, a me kahi kahua paʻa no nā ʻāpana neʻe o ka mīkini.

ʻO kekahi hoʻohana maʻamau no nā ʻāpana granite precision ma ke kahua o nā optics. He haʻahaʻa loa ka hoʻonui wela o Granite, e lilo ia i mea maikaʻi loa no nā aniani precision a me nā ʻāpana optical ʻē aʻe e pono ai ke mālama i ko lākou ʻano a me ka pololei ma lalo o nā kūlana mahana e loli nei. Loaʻa iā Granite kahi modulus elasticity kiʻekiʻe loa, kahi e kōkua ai i ka hōʻemi ʻana i ka distortion a i ʻole ke kūlou ʻana o nā ʻāpana optical.

I ka ʻoihana semiconductor, hoʻohana ʻia nā ʻāpana granite precision i ke kūkulu ʻana i nā lako nānā wafer a me nā mea hana hana precision ʻē aʻe. ʻO ke ʻano paʻa a paʻa o ka granite e hāʻawi i kahi substrate kūpono no kēia mau mea hana, e hōʻoiaʻiʻo ana i nā ana pololei a me ka hana mau i ka hala ʻana o ka manawa.

Hiki ke hana ʻia nā ʻāpana granite kikoʻī i nā nui a me nā ʻano like ʻole e kūpono i nā noi like ʻole. Hana ʻia kēia mau ʻāpana me ka hoʻohana ʻana i nā ʻenehana mīkini kūikawā e hiki ai ke hoʻokō i nā ʻae paʻa loa a me nā kiʻekiʻe kiʻekiʻe o ka pololei. Eia kekahi, ua kāohi pono ʻia ka hoʻopau ʻana o ka ʻili o nā ʻāpana e hōʻoia i nā ʻili laumania a palahalaha ʻole i nā hemahema.

I ka hopena, ʻo nā ʻāpana granite kikoʻī he ʻāpana koʻikoʻi ia o nā noi ʻoihana he nui kahi e pono ai ka pololei a me ke kūpaʻa kiʻekiʻe. ʻO nā waiwai kūikawā o ka granite e lilo ia i mea kūpono no kēia mau ʻāpana, e hāʻawi ana i ka paʻa, ke kūpaʻa, a me ka pololei i nā ʻano mea hana a me nā lako like ʻole. Ke hoʻomau nei ka holomua o ka ʻenehana, e hoʻomau ka ulu ʻana o ke koi no nā ʻāpana granite kikoʻī, e hoʻokele ana i ka hana hou a me ka holomua i nā ʻano ʻoihana like ʻole.
