Ke Hoʻākāka Hou ʻana i ka Sub-Micron Precision: Ka Hoʻohui ʻana o ka ʻenehana Granite Air Bearing i nā ʻōnaehana neʻe hou

I ke ʻano o kēia wā o ka ʻenekinia kiʻekiʻe-kiko, ʻo ka hoʻololi ʻana mai ka hoʻopili mechanical kuʻuna i ka neʻe frictionless ʻaʻole ia he ʻano maʻamau wale nō—he mea pono ia no ka ʻenehana. No nā ʻoihana e hoʻomaka ana mai ka nānā ʻana o ka wafer semiconductor a hiki i ka hana laser holomua, ʻo ka ʻimi ʻana i ka "scan kūpono" ua alakaʻi i nā ʻenekinia i kahi mea kumu: granite ʻeleʻele maoli. Ke hana ʻia kēia mea kahiko i loko o kahiKahua Hāpai Ea ʻAno Gantry, hoʻoponopono ia i nā pilikia paʻa loa i ka metrology: friction, thermal drift, a me ka mechanical hysteresis.

Ma ZHHIMG (www.zhhimg.com), ua ʻike mākou ʻaʻole wale nā ​​ʻōnaehana ultra-precision holomua he hōʻiliʻili o nā ʻāpana, akā he synergy holoʻokoʻa ma waena o ka ʻepekema mea a me ka dynamics wai. Aia ke kumu o kēia hana ma ka pilina ma waena o kahi Granite Air Guide Rail a me kāna Granite Air Slide Block e pili ana. ʻAʻole e like me nā alakaʻi pōpō recirculating kila, hana kēia mau ʻāpana ma kahi ʻili lahilahi o ka ea i hoʻopaʻa ʻia, ma waena o 5 a 10 microns ka mānoanoa. Hana kēia ʻili ea ma ke ʻano he kānana kūlohelohe, e awelika ana i nā hemahema o ka ʻili microscopic a hāʻawi i kahi pae o ka pololei i hiki ʻole i nā bearings mechanical ke hana hou.

ʻO kekahi o nā pōmaikaʻi nui o ka hoʻohana ʻana i kahiKaʻaahi Alakaʻi Ea Graniteʻo ia kona kūpaʻa dimensional kūlohelohe. I nā noi scan wikiwiki, hoʻopuka nā ala hao i ka wela ma o ka friction, e alakaʻi ana i ka hoʻonui ʻana o ka thermal a me ka "pololei drift" i nā hola o ka hana. ʻO Granite, he pōhaku igneous me kahi coefficient haʻahaʻa loa o ka hoʻonui ʻana o ka thermal, noho mau ka manaʻo ʻole i kēia mau fluctuations mahana. Ke aPoloka Paheʻe Ea Graniteke paheʻe nei ma luna o kēia ʻili, ʻo ka nele o ka hoʻopili kino ʻana ʻo ia hoʻi ʻaʻohe ʻaʻahu, ʻaʻohe haʻalulu mai nā pōpō e hoʻopuni hou ana, a ʻaʻohe pono no ka lubrication—he mea koʻikoʻi no nā wahi lumi maʻemaʻe ISO Class 1 kahi e hoʻopilikia ai ka noe aila a i ʻole ka lepo metala i ka pūʻulu hana holoʻokoʻa.

Eia nō naʻe, ʻo ke kiko o kahi ʻōnaehana neʻe e like me ka maikaʻi o kona loulou nāwaliwali loa. ʻO ia ke kumu e neʻe nei ka ʻoihana i ka ʻākoakoa Granite piha me nā wili pōpō a me nā alahao. ʻOiai ʻo nā bearings ea e hāʻawi i ka "lana" frictionless, pono e hoʻohui ʻia ka mīkini hoʻokele - pinepine kahi wili pōpō precision-ground a i ʻole kahi motika linear - me ka mālama nui. Ma ke kau ʻana i kēia mau ʻāpana hoʻokele pololei ma luna o kahi kumu granite precision-lapped, hoʻopau mākou i nā hewa alignment e hoʻopilikia pinepine i nā ʻōnaehana metala-a-pōhaku hybrid. Hōʻoia kēia ala i hoʻohui ʻia ua kaulike pono ke kikowaena o ka umekaumaha a me ke kikowaena o ka thrust, e hoʻemi ana i ka "Abbe error" hiki ke hoʻohaʻahaʻa i ka pololei ma nā wikiwiki kiʻekiʻe.

No nā OEM honua, ke koho ʻana o kahiKahua Hāpai Ea ʻAno GantryHoʻokele pinepine ʻia e ka pono no ka throughput kiʻekiʻe me ka ʻole o ka mōhai ʻana i ka repeatability. Ma kahi hoʻonohonoho gantry maʻamau, ʻae ka hoʻolālā dual-drive no ka huakaʻi format nui—he mea nui no ka nānā ʻana o FPD (Flat Panel Display) hou—ʻoiai e mālama ana i ka paʻakikī o ke ʻano i hāʻawi ʻia e ka granite cross-beam. ʻOi aku ka maikaʻi o nā waiwai damping kūlohelohe o ka granite ma mua o ka hao i hoʻolei ʻia a i ʻole ka alumini, e ʻae ana i ka ʻōnaehana e "noho" koke ma hope o ka neʻe ʻana o ka wikiwiki. ʻO kēia hōʻemi ʻana i ka manawa hoʻonoho pololei e unuhi pololei i nā units-per-hola (UPH) kiʻekiʻe no ka mea hoʻohana hope.

Pono ka hoʻolālā ʻana i kēia mau ʻōnaehana i ka hoʻomaopopo hohonu ʻana i ka "kālā hewa." He mea nui kēlā me kēia micron. Ke hana mākou i kahi hui Granite me nā wili pōpō a me nā alahao, pili kā mākou kaʻina hana i ka hoʻopaʻa lima ʻana i nā ʻili granite i nā kikoʻī Grade 00 ma mua o ka hana ʻana o kekahi hoʻouka ʻana mechanical. Hōʻoia kēia i kaKaʻaahi Alakaʻi Ea Granitehāʻawi i kahi kuhikuhi planar kūpono no ka envelope neʻe holoʻokoʻa. ʻO ka hopena he ʻōnaehana e hāʻawi ana i ka hoʻonā pae nanometer a me ka hana hou ʻana ma lalo o ka micron, i kēlā me kēia lā, ma nā wahi ʻoihana koi nui loa.

I ko mākou nānā ʻana i ka wā e hiki mai ana o ka nanotechnology a me nā kikowaena semiconductor 2nm, e hoʻonui wale ʻia ke kuleana o ka ʻenehana ea e pili ana i ka pōhaku. ʻO ke kūpaʻa o kahi Granite Air Slide Block e neʻe mālie ana ma luna o kahi alahao kikoʻī he hōʻike ia i ke ʻano o ka hui pū ʻana o nā mea kuʻuna a me nā physics hou e hoʻokuke i nā palena o ka mea hiki ke ana ʻia. Ma ZHHIMG, ke hoʻomau nei mākou i ka hoʻomaʻemaʻe ʻana i kēia mau hoʻonā i hoʻokumu ʻia i ka granite, e hōʻoia ana i loaʻa i kā mākou mau hoa ke kahua paʻa a me ka frictionless e pono ai lākou e kūkulu i ka hanauna hou o nā holomua ʻenehana.

E ʻike i nā kikoʻī loea a me nā hiki ke hoʻopilikino ʻia o kā mākou mau kahua neʻe mawww.zhhimg.com.
