Ma ke ana pololei, pili ka pololei o kāu mau mea paahana i ka maikaʻi o ka papa kuhikuhi ma lalo o lākou. Ma waena o nā kumu kuhikuhi pololei, ʻike nui ʻia nā papa papa pōhaku no ko lākou kūpaʻa kūʻokoʻa, rigidity, a me ke kūʻē ʻana i ka ʻaʻahu. Akā he aha ka mea e wehewehe ai i ko lākou kiʻekiʻe o ka pololei - a he aha ka manaʻo o ka "00-grade" flatness tolerance?
He aha ka 00-Grade Flatness?
Hana ʻia nā papa ʻāina Granite e like me nā kūlana metrology koʻikoʻi, kahi e hōʻike ai kēlā me kēia papa i kahi pae ʻokoʻa o ka palahalaha pololei. ʻO ka papa 00, i ʻōlelo pinepine ʻia ma ke ʻano he papa hana ʻoihana a i ʻole ultra-precision grade, hāʻawi i ka pae kiʻekiʻe o ka pololei i loaʻa no nā papa granite maʻamau.
No ka 00-grade granite surface plate, ʻo ka hoʻomanawanui ʻana i loko o 0.005mm no ka mika. ʻO ia hoʻi, ma luna o hoʻokahi mika ka lōʻihi o ka ʻili, ʻaʻole e ʻoi aku ka haʻalele ʻana mai ka palahalaha kūpono ma mua o ʻelima microns. ʻO ia ʻano pololei e hōʻoia i ka pau ʻana o nā hewa ana i hoʻokumu ʻia e nā ʻano like ʻole o ka ʻili - he mea koʻikoʻi i ka calibration kiʻekiʻe, ka nānā ʻana, a me ka hoʻonohonoho ʻana i nā noi ana.
No ke aha he mea nui ka palahalaha
Hoʻoholo ʻo Flatness i ka pololei o ka hiki ke hoʻohana ʻana i kahi papa honua ma ke ʻano he kuhikuhi no ka nānā ʻana a me ka hui ʻana. Hiki ke alakaʻi i nā hewa ana nui i ka nānā ʻana i nā ʻāpana pololei. No laila, he mea nui ka mālama ʻana i nā ʻaoʻao ultra-flat no ka hōʻoia ʻana i nā hopena kūlike i nā laboratories, aerospace a me nā mea kanu hana kahi e koi ʻia ai ka pololei o ka micrometer-level.
Paʻa Mea a me ka Mana Kaiapuni
ʻO ke kūpaʻa kupaianaha o nā papa pōhaku 00-grade mai ka ʻenekini hoʻonui wela haʻahaʻa o ka granite maoli a me ka ʻoi loa o ka rigidity. ʻAʻole e like me nā papa metala, ʻaʻole ʻili ka granite ma lalo o nā loli wela a i ʻole ka mana magnetic. Hoʻopili maikaʻi ʻia kēlā me kēia pā a nānā ʻia i kahi kaiapuni i mālama ʻia i ka mahana (20 ± 1°C) i mea e paʻa mau ai ka palahalaha ma lalo o nā kūlana hana.
ʻO ka nānā a me ka calibration
Ma ZHHIMG®, hōʻoia ʻia kēlā me kēia 00-grade granite surface plate me ka hoʻohana ʻana i nā pae uila kiʻekiʻe, autocollimators, a me nā interferometer laser. ʻO kēia mau mea hana e hōʻoia i ka hoʻokō ʻana o kēlā me kēia pā i nā kūlana honua e like me DIN 876, GB/T 20428, a me ISO 8512. He mea koʻikoʻi nō hoʻi ka calibration maʻamau a me ka hoʻomaʻemaʻe ʻana i ka mālama ʻana i ka pololei palahalaha lōʻihi.
Pono Hiki iā ʻoe ke hilinaʻi
Ke koho ʻana i ka pā pōhaku pōhaku no kāu ʻōnaehana ana, ʻo ke koho ʻana i ka māka kūpono e pili pono i kou hilinaʻi ana. He 00-grade granite surface plate e hōʻike ana i ke kiʻekiʻe o ka pololei o ke ana - ke kumu i kūkulu ʻia ai ka pololei maoli.
