I ka hahai mau ʻana i ka maikaʻi o ka hana ʻana, kahi e emi ana nā hoʻomanawanui dimensional mai nā micrometer a i nā nanometer, ʻo ka mokulele kuhikuhi ke kumu koʻikoʻi loa. ʻO ke kahua paʻa o ka metrology hou - ka ʻili mai kahi i loaʻa ai nā ana linear āpau - ʻo ia ka papa granite. ʻO ke kikoʻī, ʻo ka papa nānā granite kiʻekiʻe a me kona hoa kūkulu, ka papa nānā granite a i ʻole ka papa ʻili granite, ke hoʻomau nei i ka noho aliʻi, ʻoiai i ka wā o nā ʻōnaehana ana kikohoʻe holomua. Akā he aha ka mea e pili ana i kēia mea kūlohelohe, me he mea lā maʻalahi e hoʻolilo ai iā ia i mea hiki ʻole ke hoʻololi ʻia ma ke ʻano he "zero point" i nā ʻoihana koi nui loa o ka honua, mai ka hana semiconductor a i nā ʻōnaehana laser ikehu kiʻekiʻe?
Aia ka pane i ka hui ʻana o nā waiwai o nā mea kūlohelohe a me ka ʻike hana akamai i hoʻomaikaʻi ʻia no nā makahiki he ʻumi. I ke koho ʻana i kahi ʻili kuhikuhi no ka nānā koʻikoʻi, ʻoi aku nā koi ma mua o ka paʻakikī maʻalahi. ʻO ke kūpaʻa, ka lōʻihi, a me ke kūpaʻa wela ka mea nui.
ʻO ka Pōmaikaʻi Mau Loa o ka Granite ʻEleʻele Premium
ʻO ke kumu o kekahi ʻāpana granite pololei kiʻekiʻe ʻo ia ka mea maka ponoʻī. ʻAʻole e like me ka granite hina maʻamau a i ʻole ke kinikini paʻa ʻole i hoʻohana pinepine ʻia e nā mea hana ʻoi aku ka akahele, koi ke kūlana ʻoihana no ke kūpaʻa paʻa ʻole i kahi granite ʻeleʻele-gabbro kiʻekiʻe.
No ka laʻana, ua hana ʻia ka ZHHIMG® Black Granite ponoʻī i hana ʻia me ka ʻepekema no ka hana, me ka haʻaheo ʻana i kahi density kūikawā o kahi 3100 kg/m³. ʻAʻole wale kēia ʻano mineral kiʻekiʻe he helu; ʻo ia ka hōʻoia kino o ka hana. Hoʻopili pololei ka density kiʻekiʻe i ka hoʻonui ʻia ʻana o ka modulus Young, e hopena ana i kahi mea i ʻoi aku ka paʻakikī a ʻoi aku ka pale ʻana i nā ukana static a me dynamic i kau ʻia ma luna. Hōʻoia kēia paʻakikī kūlohelohe e mālama ka papa ʻaina granite i kona hoʻomanawanui flatness i kuhikuhi ʻia - i kekahi manawa a hiki i ka nanometer - ʻoiai ke kākoʻo nei i nā gantries Coordinate Measuring Machine (CMM) nui a i ʻole nā mea hana kaumaha.
Eia kekahi, he mea koʻikoʻi ka haʻahaʻa o ka conductivity thermal o ka granite a me ka coefficient haʻahaʻa loa o ka hoʻonui ʻana o ka thermal. I loko o nā lumi nānā i kāohi ʻia e ka mahana, pono e kūʻē kahi ʻili kuhikuhi i nā loli dimensional minuke i hoʻokumu ʻia e nā loli o ka mahana ambient a i ʻole ka hoʻoili wela mai ka ʻāpana e nānā ʻia ana. Ke hele nei ka mea ZHHIMG® i kahi kaʻina hana ʻelemakule kūlohelohe lōʻihi e hoʻopau loa i nā pilikia kūloko, e hōʻoiaʻiʻo ana i ka like o ka hoʻonohonoho ʻana a me ka hōʻoia ʻana i ka pau ʻana o ka hanapapa granitee hāʻawi i kahi mokulele kuhikuhi hilinaʻi, ʻaʻohe distortion no nā makahiki he ʻumi.
ʻEnekinia ʻana i ka "Zero Point": Precision Ma mua o ka Polishing Maʻalahi
ʻO ka hana ʻana i kahi papa nānā granite pololei maoli he ʻano hana noʻeau i hoʻokumu ʻia ma ka ʻepekema koʻikoʻi, e ʻoi aku ana ma mua o ka ʻeli mua ʻana a me ka ʻoki ʻana. Pili ke kaʻina hana i nā mīkini nui a kiʻekiʻe loa e hana pū ana me nā lako metrology koʻikoʻi loa, a me ke ʻano koʻikoʻi, ka ʻāpana kanaka o ka hana lima.
Hoʻohana nā alakaʻi honua ma kēia kahua i nā hale ākea a i kāohi ʻia e ke kaiapuni. Pono nā papa nānā granite kikoʻī e kaupaona ana ma luna o 100 tone a hiki i 20 mika ka lōʻihi i nā ʻōnaehana kūikawā. No ka laʻana, ʻo ka hoʻohana ʻana i nā hale hana i hoʻohaʻahaʻa ʻia i ka haʻalulu, i kāohi ʻia i ka mahana a me ka haʻahaʻa—pinepine me nā papahele sima mānoanoa, i hoʻoikaika ʻia a me nā ʻauwaha anti-vibration—he mea koi ia. Hoʻopau kēia ʻano i ka walaʻau kaiapuni, e hōʻoia ana e hana ʻia nā pae hope loa o ka manual a me ka mīkini ma lalo o nā kūlana paʻa loa.
ʻO ke kaʻina hana wili a me ka lapping kahi e hoʻokō ʻia ai ka palahalaha e pono ai. Hoʻopukapuka nui nā mea hana kikoʻī i nā mīkini lapping nui, ultra-kiʻekiʻe-kiʻekiʻe, hiki ke hana i nā ʻāpana metala a me nā ʻāpana ʻaʻole metala i nā pae kiʻekiʻe loa o ka pololei. Eia nō naʻe, ʻoiai ka mīkini holomua loa hiki ke hoʻokō i ka nui. ʻO ka calibration hope loa - ka micron hope loa o ka hoʻoponopono ʻana i ka palahalaha - ua hoʻokō maʻamau ʻia e nā mea hana lima akamai. Hoʻohana kēia mau mea hana lima, pinepine me 30 a ʻoi aku paha mau makahiki o ka ʻike, i nā ʻano hana lima-lapping ponoʻī, e hilinaʻi ana i kahi ʻike kokoke i ka instinctive, tactile e hoʻokō i nā ʻae ʻana o ka palahalaha o ka ʻili e hoʻokō a ʻoi aku paha i nā kūlana paʻa loa o ka honua, me ASME B89.3.7, DIN 876, a me JIS B 7510. ʻO kēia pā kanaka, ka mea e hoʻololi ai i kahi papa pōhaku mānoanoa i loko o kahi kuhikuhi nanometer-flat, ʻo ia ka mea e hoʻokaʻawale ai i kahi papa ʻili granite premium.
ʻO ke Kauoha Metrology: Traceability a me nā Kūlana
I ka ʻoihana ultra-precision, ʻo ke ana ʻana e like me ka maikaʻi o ka calibration o ka ʻili kuhikuhi. No kapapa nānā granitei mea e hilinaʻi ʻia ma ka honua holoʻokoʻa, pono e kīnā ʻole ʻia kāna hōʻoia a hiki ke hahai ʻia.
Hoʻāʻo piha nā mea hana alakaʻi i kēlā me kēia papa ʻili me ka hoʻohana ʻana i nā mea hana ana akamai loa o ka honua: nā interferometer laser, nā pae uila (e like me nā mea mai WYLER), a me nā probes inductive hoʻonā kiʻekiʻe (e like me nā mea mai Mahr). Ana kēia mau mea hana i ka palahalaha holoʻokoʻa, ka pololei o ka heluhelu hou ʻana, a me ka loli kūloko o ka palahalaha, pinepine i nā hoʻonā o 0.5 m a ʻoi aku paha.
ʻO ke koʻikoʻi, pono e hoʻoponopono mau ʻia nā mea ana āpau, me ka hiki ke huli ʻia i nā ʻoihana metrology honua a me ka ʻāina (e like me NIST, NPL, a i ʻole PTB). ʻO kēia pili ʻana i kahi kūlana metrology paʻa a honua ke kumu i ʻae ʻia ai nā papa nānā granite i hōʻoia ʻia ma ke ao holoʻokoʻa ma ke ʻano he kūlana gula i nā lumi calibration a me ka hoʻomalu maikaʻi. Me ka ʻole o kēia kahua nanometer-flat i hōʻoia ʻia, ʻaʻole hiki ke hōʻoia ʻia ka hana o nā lako hana pololei miliona miliona kālā—e like me nā CMM holomua, nā ʻōnaehana lithography semiconductor, a me nā mīkini laser femtosecond.
ʻO Granite ma ke ʻano he ʻāpana mīkini hope loa
ʻOiai he mea nui ka papa ʻaina granite ma ke ʻano he mea ana, ʻo kona kūlana kūkulu i nā lako hana wikiwiki a pololei hoʻi o kēia wā he mea nui like ia. Ua pani nui nā ʻāpana, nā kumu, a me nā ʻākoakoa o Granite i ka hao i hoʻolei ʻia a me nā mea kuʻuna ʻē aʻe i loko o ke kumu kūkulu o nā mīkini holomua:
-
Ka Hoʻēmi ʻana i ka Haʻalulu: Hāʻawi ka ʻano kūloko a me ke kaumaha o Granite i nā ʻano damping maikaʻi loa i hoʻohālikelike ʻia me ka metala, e hoʻopili pono ana i ka haʻalulu mīkini a me ka hoʻonui wela e hiki ke hoʻopilikia i ke kūlana sub-micron.
-
Paʻa Ana: No nā ʻāpana koʻikoʻi e like me nā ʻōnaehana ea, hāʻawi ka granite i ke kūpaʻa lōʻihi, ʻaʻole e popo, a ʻaʻole e warping e pono ai no ka mālama ʻana i nā hakahaka ea a me ke ʻano like o ke alahao alakaʻi ma luna o nā pōʻaiapuni hana nui.
-
Ka Unahi a me ka Paʻakikī: Me ka hiki ke hana i nā ʻano granite monolithic paʻakikī a me nā kumu mīkini a hiki i 20 mika ka lōʻihi, ua hana ʻia nā papa granite i nā ʻāpana i hana ʻia e ke kanaka, e hōʻike ana i nā T-slots i hoʻohui ʻia, nā mea hoʻokomo wili, a me nā ʻili ea e hana ana ma ke ʻano he iwi kuamoʻo no nā laina hana holoʻokoʻa.
Ua maopopo ka pilina mau loa o ka papa granite kiʻekiʻe. ʻAʻole ia he koena wale nō o ka metrology kuʻuna; he hopena mea ʻenehana kiʻekiʻe e ulu mau nei e hoʻokumu ana i ke kumu kuhikuhi no nā ʻoihana hana holomua loa o ka honua. I ka hoʻomau ʻana o nā koi no ka pololei o ka dimensional, ʻo ke kūpaʻa, ka lōʻihi, a me ka palahalaha hiki ke hōʻoia ʻia o ka granite ʻeleʻele premium e mau ana ka mea nui no ka hōʻoia ʻana i ka maikaʻi, ke kūlike, a me ka hana hou ma ka ʻoihana ultra-precision honua.
