He aha ka ʻāpana granite precision?

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

ʻO ka hoʻohana ʻana i ka granite ma ke ʻano he mea no nā ʻāpana kikoʻī he moʻolelo lōʻihi, e pili ana i ka poʻe ʻAigupita kahiko i hoʻohana i ka granite i ke kūkulu ʻana i kā lākou pyramids. I kēia lā, hoʻohana ʻia nā ʻāpana granite precision i nā ʻoihana mai ka ʻenekinia pololei a me ka metrology i ka optics a me ka hana semiconductor.

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

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

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

I ka ʻoihana semiconductor, hoʻohana ʻia nā ʻāpana granite precision i ke kūkulu ʻana i nā mea nānā wafer a me nā mea hana 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 ʻana i ka manawa.

Hiki ke hana ʻia nā ʻāpana granite pololei i nā ʻano nui a me nā ʻano 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 hoʻomanawanui paʻa loa a me nā pae kiʻekiʻe o ka pololei. Eia kekahi, ua hoʻomalu maikaʻi ʻia ka hoʻopau ʻana o ka ʻili o nā mea e hōʻoia ai i ka maʻemaʻe a me ka pālahalaha ʻole i nā hemahema.

I ka hopena, ʻo nā ʻāpana granite precision he ʻāpana koʻikoʻi o ka nui o nā noi ʻoihana kahi e koi ʻia ai ka pololei kiʻekiʻe a me ke kūpaʻa. ʻO nā waiwai kūikawā o ka granite e lilo ia i mea kūpono no kēia mau ʻāpana, e hāʻawi ana i ka rigidity, kūpaʻa, a me ka pololei i kahi ākea o nā mea hana a me nā mea hana. Ke hoʻomau nei ka ʻenehana i ka holomua, e hoʻomau ʻia ka noi no nā ʻāpana granite precision, e hoʻokau i ka hana hou a me ka holomua i nā ʻano ʻoihana.
