I loko o ke ao o ka mana neʻe ʻana o ka ultra-precision, aia kekahi ʻāpana e hana ana i kahi mea e kani kokoke ana i ka hiki ʻole ke hoʻomaopopo ʻia: kahi kahua kikoʻī e lana ana ma luna o kahi ʻili o ka ea he mau microns wale nō ka mānoanoa, e neʻe ana me ka ʻole o ka friction. ʻAʻole kēia he moʻolelo ʻepekema. ʻO ia ka granite air bearing—a ʻo ia ka ʻenehana hiki ke hoʻohana ma hope o ka semiconductor lithography, ka nānā ʻana o ka wafer, ka nānā ʻana o ka pila EV, a me nā noi ʻē aʻe āpau e pono ai ke kau ʻana ma ka pae nanometer.
He aha ka Bearing Air?
Hana ka mea ea ea ma ke koi ʻana i ka ea i hoʻopaʻa ʻia ma o kahi ʻili porous a i ʻole orifice-feeded, e hana ana i kahi uluna lahilahi a hoʻomau o ka ea ma waena o ʻelua mau ʻili e pili kino ana. ʻO ka ukana—he kahua, he spindle, he papa e neʻe ana—e lana maoli ana ma luna o kēia ʻili ea, ma kahi maʻamau ma waena o 5 a me 20 microns ka mānoanoa, ma muli o ka hoʻolālā a me nā koi ukana.
No ka mea, ʻaʻohe pilina kino ma waena o nā ʻili e neʻe ana a me nā ʻili paʻa, ʻaʻohe ʻano haʻalulu mīkini, ʻaʻohe ʻano paʻa-paheʻe, a ʻaʻohe ʻaʻahu. He kūlana ʻokoʻa loa kēia mai kahika hali mīkini maʻamau, ʻoiai pehea ka maikaʻi o ka mīkini ʻana—loaʻa mau kekahi kekelē o ka friction, ka ʻokoʻa microscopic o ka ʻili, a me ka lohi o ka ʻaʻahu ʻana ma luna o kona ola hana.
No ke aha ʻo Granite wale nō ke koho no nā Air Bearings
Ma ke kumumanaʻo, hiki ke kūkulu ʻia nā bearings ea ma luna o nā mea pālahalaha a paʻakikī like ʻole, akā ua lilo ka granite i koho maʻamau no ka ʻili bearings paʻa i nā noi kikoʻī kiʻekiʻe.
Paʻa o ka Palahalaha i ka Manawa. No ka mea, he haʻahaʻa loa ke kaumaha kūloko o ka granite i hoʻohālikelike ʻia me ka metala i mīkini ʻia—hoʻopaʻa ka metala i ke kaumaha i koe mai ke kaʻina hana hoʻolei a me ka mīkini ʻana, hiki ke hana i nā loli liʻiliʻi o ka nui i nā mahina a i ʻole nā makahiki—ʻoi aku ka lōʻihi o ka paʻa ʻana o ka ʻili granite i kona kikoʻī palahalaha ma mua o ka metala like. No kahi ea bearing, kahi e hilinaʻi ai ka envelope hana holoʻokoʻa i ka mālama ʻana i kahi hakahaka mau a i kāohi ʻia, he mea koʻikoʻi kēia kūpaʻa.
Paʻa Wela. He microscopic ka hakahaka ea—maʻamau he 5-20 microns. Hoʻololi ka hoʻonui wela o ke alahao alakaʻi i kēia hakahaka, e hoʻololi ana i ka hana o ka bearing a hoʻokomo i nā hewa kūlana. ʻO ka CTE o Granite ma kahi o ka hapalua o ke kila a me ka hapakolu o ka alumini. Hōʻoia kēia e paʻa ana ka pololei o ke kūlana nanometer ma luna o nā pōʻaiapuni hana 24-hola.
Hoʻokaʻawale ʻana i ka Damping a me ka Haʻalulu. Loaʻa i ka Granite kahi mana damping kūlohelohe he 10 mau manawa ʻoi aku ka nui ma mua o ke kila. Ke hui pū ʻia me ka damping viscous o ka ʻili ea, hana ka ʻōnaehana i kahi hopena "double-damping" e hoʻokaʻawale i nā ukana koʻikoʻi mai nā haʻalulu papahele a me ka walaʻau motika. He mea koʻikoʻi kēia no nā noi e like me nā kolamu kukuna electron a me nā interferometers, kahi e hōʻino ai ka haʻalulu i ka hoʻonā kiʻi.
ʻAʻole Magnetic, Uila ʻole. I nā wahi hana semiconductor a me nā mea uila, ʻo ka pale ʻana i nā kahua magnetic a me ka conductivity uila kokoke i nā kaʻina hana koʻikoʻi he koi paʻakikī pinepine ia. Hoʻokō ʻo Granite i kēia me ka ʻole o ka mālama hou ʻana.
Ka hopena "Double-Damping"
Eia ka mea e hoʻolilo ai i ka hui ʻana o ka granite-air bearing i mea kūpono loa. Hāʻawi ʻo Granite iā ia iho i ka damping kūikawā—e hōʻemi ana i ka ʻōhumu mīkini a hiki i ka 10 mau manawa i hoʻohālikelike ʻia me ka hao i hoʻolei ʻia. Hāʻawi ka ʻili ea i ka damping viscous hou aʻe, e hoʻomaʻemaʻe ana i nā haʻalulu alapine kiʻekiʻe. I ka hui pū ʻana, hana lākou i ka mea a nā ʻenekinia i kapa ai he hopena "double-damping".
ʻO ke ʻano kēia, ʻaʻole pololei wale ke kahua ea granite; he mālie ia. Neʻe mālie ke kahua, me ka ʻole o ka haʻalulu microscopic e hoʻopilikia ana i nā bearings mechanical. Hoʻopaʻa koke ia, me ka ʻole o ke kani ʻana e hiki ke hoʻopaneʻe i nā ana. A mālama ia i kona pololei i nā makahiki o ka hana, me ka ʻole o ka ʻaʻahu mālie e hoʻohaʻahaʻa i ka hana bearing mechanical.
Ma hea e hoʻohana maoli ʻia ai nā Granite Air Bearings
Ua like ka papa inoa noi me kahi huakaʻi o nā kihi kikoʻī loa o ka hana ʻana a me ka nānā ʻana o kēia au:
ʻO ka Semiconductor Lithography a me ka Wafer Inspection. Pono ka hana hou ʻana o ka sub-nanometer e hoʻohālikelike pono i nā hiʻohiʻona ma kahi wafer. Hāʻawi nā bearings ea Granite i ka neʻe frictionless, non-contact e hiki ai ke kikoʻī e pono ai no ka hana ʻana i nā chips hanauna e hiki mai ana.
Nā Mīkini Ana Hoʻohui (CMM). ʻO ka hui pū ʻana o nā alakaʻi granite precision a me nā bearings ea ke kūlana gula no nā CMM, kahi e hōʻino ai ka haʻalulu pae i ka hoʻonā ana. ʻO ka nele o ka friction a me ka stick-slip o ka bearings ea e hiki ai ke kau i ke kūlana ma nā ʻāpana nanometer.
ʻŌnaehana Ana Optical a me Laser. ʻO kēlā me kēia ʻōnaehana ana e hilinaʻi nei i ka interferometry a i ʻole ke kiʻi optical e pono ai kahi kahua neʻe ʻaʻole e hoʻolauna i ka haʻalulu a i ʻole ka hewa hoʻonohonoho. Hāʻawi nā bearings ea Granite i ke kūpaʻa e pono ai no kēia mau noi koi.
Nānā Pākahiko EV. I ka piʻi ʻana o ka hana ʻana o nā pākahiko kaʻa uila, ua ulu nui ka noi no nā ʻōnaehana nānā wikiwiki a pololei hoʻi. Hāʻawi nā pae ea Granite i ka wikiwiki a me ka pololei e pono ai no ka nānā ʻana i nā ana o ke kelepona pākahiko, ka hoʻonohonoho ʻana o ka electrode, a me nā ʻano koʻikoʻi ʻē aʻe.
ʻEli PCB a me ke Alanui. Pono ka ʻeli PCB wikiwiki i kahi kūlana wikiwiki a pololei me ka manawa hoʻonohonoho liʻiliʻi. Hiki i nā bearings ea ke hana i ka neʻe wikiwiki a me ka hoʻonohonoho e pono ai no ka hana hana kiʻekiʻe.
He aha ka mea e hoʻokaʻawale ai iā ZHHIMG®
ʻAʻole like nā ʻāpana ea granite a pau. ʻO ke ʻano o ka granite, ka pololei o ke kāʻei ʻana, a me ka ʻike o nā mea hana lima e hoʻoholo ai inā hana kahi ea e like me ke kikoʻī.
Ma ZHHIMG®, loaʻa i kā mākou granite ʻeleʻele ZHHIMG® kahi density o ≈3100 kg/m³—ʻoi aku ke kiʻekiʻe ma mua o ka hapa nui o nā granite ʻeleʻele ʻEulopa a me ʻAmelika—e hōʻoiaʻiʻo ana i ke kūpaʻa kiʻekiʻe a me ke kūpaʻa ʻana i ka ʻaʻahu. ʻO kā mākou mau wili haku, me ka ʻoi aku o 30 mau makahiki o ka ʻike lima-lapping, loaʻa i ka palahalaha pae nanometer e pono ai no nā noi ea. ʻO kā mākou hale hana mahana mau 10,000-mika kuea, i kūkulu ʻia ma luna o kahi kahua sima paʻakikī loa 1000mm me nā ʻauwaha anti-vibration hohonu 2000mm, hāʻawi i ke kaiapuni paʻa e pono ai no ka hana ʻana i nā ʻāpana o kēia kikoʻī.
A ʻo kā mākou kūpaʻa i ka maikaʻi—i hōʻuluʻulu ʻia ma kā mākou kulekele maikaʻi, "ʻAʻole hiki i ka ʻoihana kikoʻī ke koi nui loa"—e hōʻoiaʻiʻo ana e kū ana kēlā me kēia ʻāpana ea granite e waiho ana i kā mākou hale i nā kūlana honua koi nui loa.
Inā paha ʻoe e kūkulu ana i ka hanauna hou o nā lako lithography semiconductor, kahi CMM kiʻekiʻe-pololei, a i ʻole kahi ʻōnaehana nānā pila EV, ʻo ka hui pū ʻana o ka granite precision a me ka ʻenehana ea e hāʻawi i ke kumu no ka kaohi neʻe ʻana o ka nanometer-level. A ma ZHHIMG®, ua hoʻomalu mākou i kēlā hui no nā makahiki he ʻumi.
