Precision static pressure air float platform e hoʻohana ana i ka granite e like me nā hiʻohiʻona kumu a me nā pono.

Kiʻekiʻe pololei
ʻO ka palahalaha maikaʻi loa: Ma hope o ka hoʻomaʻamaʻa maikaʻi ʻana, hiki i ka granite ke loaʻa ka palahalaha kiʻekiʻe loa. Hiki i kona palahalaha ili ke hiki i ka micron a i ʻole ka ʻoi aku ka pololei, e hāʻawi ana i kahi pae paʻa paʻa, kākoʻo ākea no nā mea hana pololei, e hōʻoiaʻiʻo ana e mālama ka mea hana i ke kūlana kiʻekiʻe a me ka neʻe ʻana i ka wā o ka hana.
ʻO ke kūlana kūpaʻa maikaʻi: He haʻahaʻa haʻahaʻa loa ka Granite o ka hoʻonui ʻana i ka wela a he liʻiliʻi loa ia e nā loli wela. Ma nā ʻano wela ambient ʻokoʻa, liʻiliʻi loa ka hoʻololi ʻana o ka nui, hiki ke mālama pono i ka pololei o nā mea hana, ʻoi aku ka maikaʻi no ka machining precision sensitive a me nā manawa ana.

ʻO ka rigidity kiʻekiʻe a me ka ikaika
ʻOi aku ka maikaʻi o ka lawe ʻana: He kiʻekiʻe a me ka paʻakikī o Granite, me ka ikaika compressive ikaika a me ka ikaika kulou. Hiki iā ia ke pale aku i nā mea hana kaumaha a me nā mea hana me ka ʻole o ka deformation maopopo, e hōʻoiaʻiʻo ana i ka paʻa a me ka hilinaʻi o ka hana pono.
ʻO ke kūpaʻa haʻalulu ikaika: ʻo ke ʻano o loko o ka granite he ʻeleʻele a ʻaʻahu, a he mau hiʻohiʻona damping maikaʻi, hiki ke hoʻopili pono a hoʻemi i ka ikehu vibration. ʻO kēia ka mea e hiki ai i nā mea hana i hoʻokomoʻia ma luna o ka granite precision base no ka mālamaʻana i ka hana paʻa i loko o kahi'ōniu vibration paʻakikī, e hōʻemi ana i ka hopena o ka haʻalulu i ka pololei o ka mīkini a me nā hopena ana.
Kūleʻa maikaʻi ke komo
ʻAʻole maʻalahi ke ʻaʻahu: He kiʻekiʻe ka paʻakikī o ka Granite a me ke kūpaʻa ʻana o ka ʻili. Ma ke kaʻina hana hoʻohana lōʻihi, ʻoiai inā i hoʻokau ʻia i kahi ʻano o ka friction a me ka ʻaʻahu, hiki ke mālama maikaʻi ʻia ka pololei o ka ʻili, no laila e hoʻolōʻihi i ke ola lawelawe o ke kumu a hoʻemi i ke kumukūʻai mālama o nā mea hana.
Ka paʻa ʻana o ka maikaʻi o ka ʻili: No ka mea ʻaʻole maʻalahi ka granite e ʻaʻahu, hiki i kona ʻili ke hoʻomau mau a paʻakikī, kahi e hoʻomaikaʻi ai i ka pololei o ka neʻe ʻana a me ka paʻa o nā mea hana, akā maʻalahi hoʻi e hoʻomaʻemaʻe a mālama, e hōʻemi ana i ka hoʻonui ʻana o ka lepo a me ka haumia adsorption i hoʻokumu ʻia e ka ʻili.

ʻO ke kūpaʻa ʻino
Paʻa kemika kiʻekiʻe: He kūpaʻa kemika maikaʻi ka Granite a ʻaʻole maʻalahi ke hoʻopau ʻia e ka waikawa, alkali a me nā mea kemika ʻē aʻe. Ma kekahi mau wahi hana paʻakikī, e like me nā wahi e noho ai nā kinoea corrosive a i ʻole nā ​​​​wai, hiki i ka granite precision base ke mālama i kāna hana a me ka pololei me ka ʻole o ka hopena, a he lōʻihi kona ola.
ʻO ka haʻahaʻa wai haʻahaʻa: He haʻahaʻa ka wai o ka granite, hiki ke pale pono i ka wai mai ke komo ʻana i loko a pale aku i nā pilikia e like me ka hoʻonui, deformation a me ka corrosion i hoʻokumu ʻia e ka wai. Hiki i kēia hiʻohiʻona ke hoʻohana maʻamau i ka base precision granite i nā wahi pulu a i ʻole i nā kūlana kahi e pono ai ka hoʻomaʻemaʻe.
Pili kaiapuni non-magnetic
Palekana kaiapuni ʻōmaʻomaʻo: ʻO Granite kahi ʻano pōhaku maoli, ʻaʻohe mea ʻino, ʻaʻohe haumia i ke kaiapuni. I loko o ka hana ʻenehana hou, e kālele ana i ka mālama ʻana i ke kaiapuni, hana kēia hiʻohiʻona i ke kumu kūpono o ka granite i kahi koho kūpono.
Non-magnetic interference: ʻAʻole magnetic ka Granite ponoʻī, ʻaʻole ia e hoʻopuka i ka hoʻopili magnetic i nā mea kani a me nā mea hana. He mea nui kēia no kekahi mau mea hoʻonaʻauao maʻamau, e like me nā microscopes electron, nuclear magnetic resonance meters, etc., e hōʻoia i ka hana maʻamau o nā mea hana a me ka pololei o nā hopena ana.
