Ma ʻō aku o ka Papa ʻIli: Pehea e lilo ai ka Papa ʻIli Ana Granite i Kuhikuhi Metrology Loa o ka Honua?

I ka heihei e hoʻomau nei i ka palena nanometer, ulu nui nā koi i kau ʻia ma ka pololei o ka hana ʻana. Hoʻolālā nā ʻenekinia i nā ʻōnaehana ikaika me nā loop feedback sub-micron a hoʻohana i nā mea exotic, akā ʻo ke ana hope loa o ka maikaʻi e iho pinepine i ke kahua maʻalahi a paʻa loa i loaʻa: granite precision. ʻO kapapa ana ʻili granite, e lawelawe pinepine ana ma ke ʻano he Granite Metrology Table, ʻaʻole ia he ʻāpana lako wale nō; ʻo ia ke kino kino o ka mokulele zero, ke kiko kuhikuhi paʻa ʻole e hōʻoia i nā ʻāpana ʻē aʻe a pau i loko o kahi ʻōnaehana kiʻekiʻe.

ʻO ka hopena piha—e komo pū ana me ka papa ʻili granite ʻeleʻele pololei ponoʻī, ka papa ʻili granite kūikawā me ke kākoʻo, a me ka papa ana granite piha me ke kū—e hōʻike ana i ka piko o ke kūpaʻa dimensional passive. ʻO kēia mau mea hana ke heleuma e kānana ʻia ai ka haunaele o ke kaiapuni hana, e hōʻoiaʻiʻo ana he hiki ke hahai ʻia a hilinaʻi ʻia nā hopena ana.

ʻO ke Kino Kūʻē ʻole o ka Papa ʻIli Granite ʻEleʻele Precision

ʻO ke hilinaʻi paʻa ʻole i kau ʻia ma ka granite ma luna o nā mea ʻē aʻe (e like me ke kila a i ʻole ka sima polymer) ua paʻa i loko o ʻelua mau waiwai kino koʻikoʻi a passive: ke kūpaʻa wela kūikawā a me ka damping haʻalulu kiʻekiʻe.

Paʻa Wela: Ka Pōmaikaʻi CTE Haʻahaʻa

I loko o kekahi ʻano kaiapuni i kāohi ʻia e ke aniau, ʻaʻole hiki ke pale ʻia nā loli iki o ka mahana. No nā mea hana metala, hoʻolauna kēia i ka paʻa ʻole o ka dimensional ma muli o ko lākou Coefficient of Thermal Expansion (CTE) kiʻekiʻe. Hiki i kahi kiʻi kila ke hoʻololi i kekahi mau micrometer ma luna o kahi loli liʻiliʻi o ka mahana, e hoʻopilikia koke ana i ka pololei.

Pololei ʻeleʻelenā papa ʻili granite, ʻoiai nā mea i loaʻa mai nā waihona geological kiʻekiʻe loa (e like me ka mea a ZHHIMG e kokoke ana i 3100 kg/m³), loaʻa iā ia kahi CTE haʻahaʻa loa. ʻO kēia waiwai mea kūlohelohe e hōʻoiaʻiʻo ana ua hoʻemi ʻia ka loli dimensional o ka ʻili ana, e hāʻawi ana i kahi kuhikuhi e mau ana me ka nānā ʻole i nā ʻano loli mahana ambient maʻamau. Eia kekahi, ʻo ka inertia thermal nui o ka granite density kiʻekiʻe e kōkua iā ia e kūʻē i nā gradients thermal wikiwiki, e hōʻoiaʻiʻo ana ʻaʻole e hoʻololi ka wela i hana ʻia e ka hoʻopili ʻana a i ʻole nā ​​​​lako ana i ke ʻano o ka ʻili.

Hana Hoʻemi: Hoʻopau i ke Kaiapuni

I loko o kahi keʻena hoʻokolohua metrology, pono e hoʻokaʻawale ʻia ka pololei o ka mīkini mai nā haʻalulu papahele ambient. Hāʻawi ke ʻano crystalline o Granite iā ia i kahi mana damping kūloko kiʻekiʻe, ʻo ia hoʻi ke omo koke nei i ka ikehu mechanical a hoʻololi iā ia i wela liʻiliʻi. Ke kau ʻia nā Mea Hana Ana Granite kiʻekiʻe ma ka pā, hoʻopau maikaʻi ka granite i ka resonance, e pale ana i ka walaʻau o ke kaiapuni mai ka hōʻino ʻana i nā ana palupalu i hana ʻia e CMMs, optical profilers, a i ʻole laser interferometers. ʻAʻole hiki ke kūkākūkā ʻia kēia ʻano kinetic mālie no ka nānā ʻana o ka nanoscale.

Mai ka Papa ʻAi a i ka ʻŌnaehana: ʻO ka Papa Ana Granite me ke Kū

ʻOiai ʻo ka papa granite ponoʻī e hāʻawi i ke kūpaʻa, ʻo ka papa ana granite me ke kū e hoʻololi i ka ʻili passive i kahi kikowaena metrology hana piha. ʻO ka hoʻolālā ʻana o ka ʻōnaehana kākoʻo he mea koʻikoʻi like ia me ka mea o ka papa.

ʻO ka hoʻohui ʻana o kahi papa ʻili granite me ke kākoʻo ua hana ʻia e mālama i ka pono geometric i hōʻoia ʻia o ka papa. Hoʻolālā pinepine ʻia nā ʻano kākoʻo e hoʻohālikelike pololei me nā kiko Airy i helu ʻia a i ʻole nā ​​kiko Bessel o ka papa, ʻo ia nā kiko kākoʻo kūpono e hoʻolaha like i ke kaumaha a hōʻemi i ka deflection ma ka ʻili holoʻokoʻa. No nā papa nui loa a kaumaha paha, hoʻohana ʻia nā ʻōnaehana kākoʻo multi-point paʻakikī, e hōʻike pinepine ana i nā wāwae pae hoʻololi a i ʻole nā ​​​​pads hoʻokaʻawale haʻalulu i hoʻohui ʻia.

ʻO kahi papa ana granite kiʻekiʻe me ke kū e hōʻoiaʻiʻo ana i ka mālama ʻia ʻana o ka pālahalaha i hōʻoia ʻia o ka pā ma lalo o ke kaumaha. ʻO kēlā me kēia hoʻohaʻahaʻa ʻana i ka paʻakikī o ke kū a i ʻole ka pololei o ka pae ʻana e unuhi koke ʻia i ka hoʻopilikia ʻana, e hoʻolilo ana i ka pā holoʻokoʻa i mea ʻole no ka hana pololei kiʻekiʻe. No laila, ua manaʻo pinepine ʻia ka ʻōnaehana papa piha he ʻāpana Papa Granite Metrology hoʻokahi a hoʻomaʻemaʻe ʻia, i hoʻopaʻa pono ʻia a hōʻoia ʻia ma kahi ma ka hale o ka mea kūʻai aku.

ʻO ke kaiaolaola o nā mea hana ana Granite

Hoʻomaopopo ʻia ka pono o ka papa ana ʻili granite ma o nā Mea Hana Ana Granite e hele pū ana. Pono e hana ʻia kēia mau mea pono—nā huinaha granite, nā kihi pololei, nā poloka V, a me nā ʻaoʻao like—me ka mea granite kiʻekiʻe like e hōʻoia i ka like ʻana o ka mea ma o ka hoʻonohonoho ana. He mea nui kēia no ka mālama ʻana i ke kaulike wela a me ka damping haʻalulu like ma nā mea āpau e pili ana i ke kaʻina hana nānā.

I ka nānā ʻana i ke kūlike o kahi mea paʻakikī, no ka laʻana, pono e hoʻonohonoho pono ʻia a hōʻoia ʻia ke ʻano like o ka huinahā granite e pili ana i ka pā, ke pololei o ka lula granite, a me ka pālahalaha o ka papa ana ʻili granite. ʻO ke kūpaʻa hui o kēia mau mea hana—e hoʻohana ana i nā waiwai waiwai kiʻekiʻe o ka granite—e hōʻoiaʻiʻo ana he mau hewa geometric i ʻike ʻia i loko o ka workpiece, ʻaʻole i ka ʻōnaehana ana.

Ka Mana o ka Papa a me ka Hana Lima

ʻO ka hana ʻana o kahi papa ʻili granite ʻeleʻele kikoʻī o ka honua e ʻoi aku ma mua o ka hana wale ʻana; pono ia i ka hui pū ʻana o ka ʻenehana holomua a me ke akamai kanaka i hiki ʻole ke ana ʻia.

1. Ka Mana Nui: Pono nā mea hoʻolako alakaʻi i ke kahua e lawelawe ai i nā papa metrology nui loa o ka honua, e koi ana i nā lako CNC kūikawā i hiki ke lawelawe i nā ʻāpana i ʻoi aku ma mua o 100 tons a me ka lōʻihi o ka lapping o 20m.

2. Pololei Hōʻoia: Hoʻokō ʻia ka palahalaha hope loa ma o ke kaʻina hana paʻakikī o ka paʻi lima ʻana, i hana ʻia e nā mea hana akamai me nā makahiki he ʻumi o ka ʻike. ʻO ko lākou hiki ke hoʻokō i ka palahalaha Papa 00 a i ʻole Papa A, i ana ʻia ma nā hapa o ka micron a i ʻole nanometers, ua hōʻoia ʻia me ka hoʻohana ʻana i nā mea hana akamai e like me nā laser interferometers, hiki ke hahai ʻia i nā kūlana honua (NIST, PTB, NPL).

3. Hoʻokō Honua: Pono e hōʻoia ʻia ka ʻōnaehana maikaʻi i nā kūlana honua he nui (ISO 9001, 14001, 45001) a hiki ke hōʻoia i nā papa i nā kūlana dimensional like ʻole, me DIN, ASME, JIS, a me GB, e hōʻoiaʻiʻo ana ua hoʻokō ka Granite Metrology Table i nā koi koʻikoʻi loa ma ka honua holoʻokoʻa.

ʻO ke ola lōʻihi a me ka mana o kēia mau Mea Hana Ana Granite e hōʻike ana i kahi kumumanaʻo kumu: i ka wā o ka automation dynamic, pono e passive, paʻa, a hiki ke hahai ʻia ka ʻoiaʻiʻo geometric. ʻO ka papa ʻili granite me ke kākoʻo, e lawelawe ana ma ke ʻano he mokulele zero-reference hope loa, ke waiho nei i ke kahua paʻa ʻole no kēlā me kēia lele ʻenehana i ka ʻenekinia ultra-precision.
