I ke ana pololei ʻana, hilinaʻi nui ka pololei o kāu mau mea hana i ka maikaʻi o ka ʻili kuhikuhi ma lalo o lākou. Ma waena o nā kumu kuhikuhi pololei āpau, ua ʻike nui ʻia nā papa ʻili granite no ko lākou kūpaʻa kūikawā, paʻakikī, a me ke kūpaʻa i ka ʻaʻahu. Akā he aha ka mea e wehewehe ai i ko lākou pae pololei - a he aha ka manaʻo maoli o ka hoʻomanawanui pālahalaha "00-grade"?
He aha ka pālahalaha 00-Grade?
Hana ʻia nā papa ʻili Granite e like me nā kūlana metrology paʻa, kahi e hōʻike ai kēlā me kēia papa i kahi pae ʻokoʻa o ka pololei o ka pālahalaha. ʻO ka papa 00, i kapa pinepine ʻia ʻo ka papa laboratory-grade a i ʻole ultra-precision grade, hāʻawi i ka pae kiʻekiʻe loa o ka pololei i loaʻa no nā papa granite maʻamau.
No kahi papa ʻili granite 00-grade, ʻo ka hoʻomanawanui pālahalaha maʻamau i loko o 0.005mm no ka mika. ʻO ke ʻano kēia, ma luna o kekahi lōʻihi hoʻokahi mika o ka ʻili, ʻaʻole e ʻoi aku ka ʻokoʻa mai ka pālahalaha kūpono ma mua o ʻelima microns. ʻO kēlā ʻano pololei e hōʻoiaʻiʻo ana ua hoʻopau loa ʻia nā hewa ana i hoʻokumu ʻia e nā hewa ʻili - he mea nui ia i ka calibration kiʻekiʻe, ka nānā ʻana o ka optical, a me nā noi ana hoʻonohonoho.
No ke aha he mea nui ka pālahalaha
ʻO ka palahalaha ke kumu o ka pololei o ka papa ʻili e hiki ai ke lilo i kuhikuhi no ka nānā ʻana i nā ana a me ka ʻākoakoa ʻana. ʻOiai kahi ʻokoʻa liʻiliʻi loa hiki ke alakaʻi i nā hewa ana nui i ka nānā ʻana i nā ʻāpana kikoʻī. No laila, he mea nui ka mālama ʻana i nā ʻili pālahalaha loa no ka hōʻoia ʻana i nā hopena kūlike i nā keʻena hoʻokolohua, nā hale hana aerospace, a me nā hale hana hana kahi e pono ai ka pololei o ka pae micrometer.
Ka Paʻa o nā Mea a me ka Mana Kaiapuni
ʻO ke kūpaʻa kupaianaha o nā papa granite 00-grade e pili ana i ka coefficient hoʻonui wela haʻahaʻa o ka granite maoli a me ka paʻakikī maikaʻi loa. ʻAʻole e like me nā papa metala, ʻaʻole e wili ka granite ma lalo o nā loli mahana a i ʻole ka mana magnetic. Hoʻopaʻa pono ʻia kēlā me kēia papa a nānā ʻia i loko o kahi ʻano i kāohi ʻia e ka mahana (20 ± 1°C) e hōʻoia i ka palahalaha mau ʻana ma lalo o nā kūlana hana.
Nānā a me ka Hoʻoponopono
Ma ZHHIMG®, ua hōʻoia ʻia kēlā me kēia papa ʻili granite 00-grade me ka hoʻohana ʻana i nā pae uila kiʻekiʻe, nā autocollimators, a me nā laser interferometers. Hōʻoia kēia mau mea hana e kūlike ana kēlā me kēia papa a ʻoi aku paha i nā kūlana honua e like me DIN 876, GB/T 20428, a me ISO 8512. He mea nui nō hoʻi ka hoʻoponopono mau ʻana a me ka hoʻomaʻemaʻe ʻana no ka mālama ʻana i ka pololei o ka palahalaha no ka wā lōʻihi.
Pololei Hiki iā ʻOe ke Hilinaʻi
I ke koho ʻana i kahi papa ʻili granite no kāu ʻōnaehana ana, ʻo ke koho ʻana i ka māka kūpono e hoʻopilikia pololei i kou hilinaʻi ana. Hōʻike ka papa ʻili granite 00-grade i ka piko o ka pololei o ke ana - ke kahua e kūkulu ʻia ai ka pololei maoli.
