Ma ke kahua o ka hana pololei a me ka noiʻi ʻepekema kiʻekiʻe, ʻo ke koho kumu o ka precision static pressure air floating platform ke kumu nui e hoʻoholo ai i kāna hana. ʻO ke kumu kikoʻī Granite a me ka base ceramic ko lākou mau hiʻohiʻona ponoʻī, e hōʻike ana i nā pono like ʻole a me nā hiʻohiʻona i ke kūpaʻa, ka mālama pono, ka lōʻihi a me nā mea ʻē aʻe.
Paʻa: ʻO ke ʻano kūlohelohe me ka synthetic
Ma hope o ka lōʻihi o ka hoʻololi ʻana i ka honua, ua hui pū ʻia ka granite e ka quartz, feldspar a me nā minerala ʻē aʻe, e hana ana i kahi ʻano paʻa a ʻano like. Ma ke alo o ka haalulu o waho, e like me ka haʻalulu ikaika i hana ʻia e ka hana ʻana o nā lako nui i loko o ka hale hana hale hana, hiki i ke kumu granite ke hoʻopaʻa pono a hoʻemi ʻia, hiki ke hoʻemi i ka amplitude vibration o ka precision static pressure ea lana ana ma mua o 80%, e hāʻawi ana i kahi kumu hana paʻa no ka paepae e hōʻoia i ka neʻe ʻana i ka neʻe ʻana i ka kiʻekiʻe-precision. No ka laʻana, i ke kaʻina hana lithography o ka hana ʻana i ka semiconductor chip, hiki i kahi kumu granite paʻa ke hōʻoia i ka hana pololei o nā lako lithography chip a hoʻokō i ke ʻano kiʻekiʻe o nā hiʻohiʻona chip.
Hana ʻia ke kumu seramika e ka synthesis artificial a me ka ʻenehana kiʻekiʻe, a ʻo kona ʻano i loko ke ʻano like ʻole a loaʻa nā hiʻohiʻona vibration damping maikaʻi. I ka hana ʻana me ka haʻalulu maʻamau, hiki iā ia ke hana i kahi kaiapuni hana paʻa no ka precision static pressure air floating platform. Eia nō naʻe, i ke alo o ka ikaika kiʻekiʻe a me ka haʻalulu hoʻomau, ʻoi aku ka haʻahaʻa o kona vibration attenuation i ka kumu granite, a he paʻakikī ke hoʻemi i ka hoʻohaʻahaʻa haʻahaʻa i ka haʻahaʻa haʻahaʻa haʻahaʻa, hiki ke loaʻa i kekahi hopena i ka neʻe ultra-precision o ka paepae.
Paʻa pololei: hoʻonui haʻahaʻa o nā pono kūlohelohe a me ka mana hana o ka pololei
ʻIke ʻia ʻo Granite no kona haʻahaʻa haʻahaʻa loa o ka hoʻonui wela, maʻamau ma 5-7 ×10⁻⁶/℃. I ka hoʻololi ʻana o ka mahana, hoʻololi liʻiliʻi ka nui o ka base precision granite. Ma ke kahua o ka astronomy, ua hoʻopili ʻia ka ʻenekini static pressure air float platform no ka hoʻoponopono maikaʻi ʻana i ka lens telescope me ke kumu granite, ʻoiai inā he mea nui ka ʻokoʻa o ka mahana ma waena o ke ao a me ka pō, hiki iā ia ke hōʻoia i ka hoʻonohonoho pono ʻana o ka lens i ka pae submicron, e kōkua ana i nā astronomers e hopu i ka dynamics maalea o nā kino lani mamao.
ʻOi aku ka maikaʻi o nā mea seramika ma ke ʻano o ka paʻa wela, a ʻo ka coefficient o ka hoʻonui wela o kekahi mau seramika hana kiʻekiʻe hiki ke haʻahaʻa e like me ka aneane ʻole a hiki ke hoʻoponopono pololei ʻia ma o ka hoʻokumu ʻana a me ke kaʻina hana. I kekahi mau mea ana wela-ko'iko'i ki'eki'e-pololei, ke kumu ceramic hiki ke mālama i ka nui paʻa ke hoʻololi ka mahana, e hōʻoia i ka pololei o ka neʻe o ka precision static kaomi ea lana anuu. Eia nō naʻe, ʻo kona kūpaʻa pololei lōʻihi i nā noi kūpono e pili ana i nā mea e like me ka ʻelemakule waiwai a pono e hōʻoia hou ʻia.
ʻO ka lōʻihi: ʻO ka pōhaku maoli ʻoʻoleʻa kiʻekiʻe a me nā mea synthetic kū i ka corrosion
He kiʻekiʻe ka paʻakikī o Granite, hiki i ka paʻakikī Mohs ke hiki i ka 6-7, maikaʻi ke pale ʻana. I loko o ka ʻenehana ʻepekema ʻenehana, ʻo ka mea i hoʻohana pinepine ʻia ka precision static pressure air float platform, hiki i kona kumu granite ke pale pono i ka nalowale o ka friction no ka wā lōʻihi, ke hoʻohālikelike ʻia me ke kumu maʻamau, hiki ke hoʻonui i ka pōʻai mālama o ka paepae ma mua o 50%, hoʻemi i nā kumukūʻai mālama pono, a hōʻoia i ka hoʻomau o ka hana noiʻi ʻepekema. Eia nō naʻe, palupalu nā mea granite, aia ka pilikia o ka haki ʻana i ka wā i hoʻopilikia ʻia.
ʻAʻole paʻakikī wale ke kumu seramika, akā loaʻa nō hoʻi ke kūpaʻa corrosion maikaʻi loa. I loko o nā ʻoihana ʻenehana kahi e loaʻa ai ka pilikia o ka corrosion kemika, e like me ka precision hydrostatic air flotation platforms i nā mea nānā huahana kemika, kūʻē nā kumu seramika i nā kinoea corrosive a i ʻole wai, e mālama ana i ka pono o ka ʻili a me nā waiwai mechanical no ka manawa lōʻihi. I loko o ke kaiapuni koʻikoʻi e like me ka haʻahaʻa kiʻekiʻe, ʻoi aku ka maikaʻi o ka hana paʻa o ka base ceramic ma mua o ke kumu granite.
ʻO ke kumukūʻai hana a me ka paʻakikī o ka hana ʻana: ʻo ka luʻu ʻana o ka pōhaku maoli a me ka paepae ʻenehana o ka synthesis artificial
He paʻakikī ka mining a me ka lawe ʻana i nā mea waiwai granite, a pono ka hana ʻana i nā mea hana kiʻekiʻe a me ka ʻenehana. Ma muli o kona paʻakikī kiʻekiʻe, brittleness, ʻokiʻoki, wili, polishing a me nā kaʻina hana ʻē aʻe e hiki ke hāʻule, māwae, kiʻekiʻe kiʻekiʻe o ka ʻōpala, e hopena i nā kumukūʻai kiʻekiʻe.
Ke hilinaʻi nei ka hana kumu ceramic i ka synthesis kiʻekiʻe a me ka ʻenehana machining precision, mai ka hoʻomākaukau ʻana i nā mea maka, ka hoʻoheheʻe ʻana i ka sintering, pono e hoʻomalu pono ʻia kēlā me kēia hana. ʻO ka noiʻi mua a me ka hoʻomohala ʻana a me ka hoʻokomo ʻana i nā mea hana he nui, ka paepae ʻenehana kiʻekiʻe. Eia nō naʻe, me ka hoʻonui ʻana i ka nui o ka hana ʻana, manaʻo ʻia e hoʻemi ʻia ke kumukūʻai, a loaʻa iā ia ke kumu kūʻai kūpono i nā noi kiʻekiʻe.
Ma ke ʻano holoʻokoʻa, hana maikaʻi nā kumu kumu granite i ka paʻa holoʻokoʻa a me ka lōʻihi maʻamau, ʻoiai ʻo nā kumu seramika i loaʻa nā pono kūʻokoʻa i ka hiki ke hoʻololi i ka wela a me ka lōʻihi o ka corrosion. Pono ke koho ʻana i ke kumu ma luna o ke ʻano noiʻi kikoʻī, nā kūlana kaiapuni a me nā kumukūʻai kumu kūʻai o ka paepae lele lele lele.
