Pehea e hoʻokō ai nā Ultra-Precision Granite Air Bearings i ka Zero-Friction Frictionless Linear Motion?

Hoʻokomo nā alakaʻi pōpō mīkini i ka friction microscopic, backlash, a me ka ʻaʻahu mechanical, ka mea e kaupalena ai i ka hana hou ʻana i ke kūlana ma ka automation kiʻekiʻe. Hoʻopau nā bearings ea granite ultra-precision i ka hoʻopili kino ʻana ma o nā ukana lana ma luna o kahi papa micro-thin o ka ea i hoʻopaʻa ʻia. Ma ka hoʻohana ʻana i ka palahalaha piha o ka granite ʻeleʻele ZHHIMG® (3100kg/m³), hāʻawi kēia mau ʻōnaehana i ka neʻe ʻole o ka friction, ʻaʻohe hysteresis, a me ka hoʻonā kūlana sub-nanometer.

Hoʻopau piha ʻana i ka haʻalulu mīkini a me ka ʻaʻahu ʻāpana

ʻO ka pilina kino ma waena o nā ʻāpana e neʻe ana e hana i ka friction hiki ʻole ke pale ʻia, e hopena ana i ka hōʻino ʻana o nā ʻāpana a me ka nalowale o ka pololei i ka hala ʻana o ka manawa. Hana nā bearings ea Granite ma o kahi hakahaka ea 5 a 10-micron mau, e hoʻopau loa ana i ka pilina paʻa-a-paʻa. Hōʻoia kēia hoʻolālā zero-friction e mālama kāu mau pae motika linear i ka pololei like i hōʻoia ʻia e ka hale hana ma nā piliona o nā pōʻaiapuni hana.

Ka hana hou ʻana o ka Sub-Nanometer Positioning ma o ke alakaʻi Zero-Backlash

Loaʻa i nā ala alakaʻi mīkini nā hopena paʻa-paheʻe, kahi e pono ai ka ikaika hou e hoʻomaka ai i ka neʻe ʻana, e hana ana i nā overshoots kūlana liʻiliʻi. Ma muli o ka lana manuahi ʻana o nā bearings ea, pane koke lākou i nā hoʻokomo motika linear fractional me ka ʻole o ka stiction a i ʻole backlash. ʻO kēia fluidity i kūlike ʻole e hiki ai i nā ʻōnaehana hana laser ke hoʻokō i ka hana hou ʻana o ka sub-nanometer hilinaʻi.

Hoʻomaʻemaʻe ka hopena awelika kūlohelohe i nā hemahema liʻiliʻi o ka ʻili

ʻOiai nā ʻili pālahalaha, aia nā ʻokoʻa liʻiliʻi o ka micro-topography ke nānā ʻia ma lalo o kahi microscope. Ke holo ka pad ea ma luna o kā mākou ala granite ʻeleʻele i uhi lima ʻia, hana ka ʻili ea i hoʻopaʻa ʻia ma ke ʻano he kānana hoʻohui kūlohelohe. Hoʻohālikelike kēia kaomi ʻili ea i nā ʻokoʻa microscopic o ka ʻili, e hopena ana i kahi pololei o ka huakaʻi linear e ʻoi aku ana ma mua o ka pālahalaha kino o ke ala.

ʻO ke kūkulu ʻana o ka lumi maʻemaʻe ʻaʻohe mālama a me ka lumi maʻemaʻe

Pono nā bearings mechanical i ka lubrication aila mau, kahi e huki ai i ka grit abrasive airborne a me nā gas i waho i loko o nā keʻena vacuum. Hoʻohana nā bearings ea Granite i ke kinoea maʻemaʻe a maloʻo i hoʻopaʻa ʻia, ʻaʻohe pono o nā wai lubrication. Hoʻopau kēia hana kūpono me ka lumi maʻemaʻe i ka haumia particulate, e lilo ia i koho mua no ka semiconductor lithography a me nā wahi vacuum.

Ka Nānā ʻana i ke ʻAno Alakaʻi: Nā Bearings Ea Granite vs. Nā Alakaʻi Linear Mechanical

Nā Nīnau i Nīnau Pinepine ʻia (FAQ)

Q1: ʻEhia ka nui o ke kaomi ea e pono ai kahi bearing ea granite e hana?

A1: Hana maikaʻi ka hapa nui o nā bearings ea granite ʻoihana ma ke kaomi paʻa ma waena o 4.0 a 6.0 bar (60 a 90 PSI). Pono e kānana pono ʻia ka lako ea e wehe i ka wai, ka ʻaila, a me nā ʻāpana i ʻoi aku ka nui ma mua o 0.1 microns.

Q2: E hōʻino nui anei ka mīkini i ka nalowale koke ʻana o ke kaomi ea?

A2: Hoʻolālā mākou i kā mākou mau ʻōnaehana me nā palena palekana i hoʻohui ʻia. Inā hāʻule ke kaomi ea, e kau mālie ka papa bearing ma luna o ke ala granite ʻeleʻele maoli. Ma muli o ka granite e lubricate ponoʻī a ʻaʻole e hoʻonāukiuki, pale ia i ka hoʻopaʻa koke ʻana o ke ʻano.

Q3: He aha ka ʻokoʻa pālahalaha kiʻekiʻe loa i ʻae ʻia no ke ala granite?

A3: No ka mālama ʻana i kahi hakahaka ea 5-micron paʻa loa, pono e hoʻopili ʻia ke ala alakaʻi granite i kahi kikoʻī pālahalaha kupaianaha, ʻoi aku ka liʻiliʻi ma mua o 1.0 micron no ka mika, i lawelawe ʻia i loko o kā mākou hale hana mahana mau.

Q4: Hiki ke hoʻohana ʻia nā bearings ea granite i nā wahi keʻena vacuum?

A4: ʻAe. No nā wahi vacuum, hoʻokō mākou i nā bearings ea vacuum-preloaded (VPL) kūikawā. Hoʻohui kēia mau hoʻonohonoho i ke kaomi ea maikaʻi me ke apo hoʻokaʻawale vacuum, e pale ana i ka ea mai ka pakele ʻana i loko o ke keʻena.

Q5: Pehea e hoʻokō ai ʻo ZHHIMG i ka ʻoʻoleʻa kiʻekiʻe i loko o kahi bearing non-contact?

A5: Hoʻonui ka paʻakikī o ke ea i ka emi ʻana o ka hakahaka ea. Ma ka hoʻomaikaʻi ʻana i nā ʻauwaha hoʻolaha ea, ke kiʻekiʻe lele, a me ka nui o ka pad ma o ka nānā ʻana i nā mea finite (FEA), hoʻonui mākou i ka paʻakikī o ke kiʻiʻoniʻoni e kūʻē i nā ukana dynamic kiʻekiʻe me ka ʻole o ka deflecting.

Q6: He aha nā noi maʻamau e pono ai nā bearings ea granite ZHHIMG®?

A6: Hoʻohui nui ʻia lākou i loko o nā ʻōnaehana nānā wafer semiconductor, nā scanner hōʻike panela pālahalaha, nā mīkini ʻoki laser ultra-precision (femtosecond/picosecond), nā mea hana hoʻonohonoho CT X-ray ʻoihana, a me nā mea ʻike metrology automated kiʻekiʻe.
