Luna Hoʻomalu Huinahā Granite

Hana ka huinahā granite ma ke ʻano he kūlana kuhikuhi geometric mua, me kāna noi metrological nui ʻo ia ka loiloi pololei o ʻekolu mau hoʻomanawanui geometric kumu:
1. Loiloi perpendicularity: Loiloi helu o ka ʻokoʻa angular ma waena o ke axis spindle mīkini, ke kuhikuhi neʻe ʻana o ka paheʻe, a me ka mokulele kuhikuhi papa hana—hana pinepine ʻia e like me ISO 1101 a hōʻoia ʻia ma o ka hoʻonohonoho optical a i ʻole ka dial indicator probing;
2. Nānā ʻana i ke ʻano like ʻole: Ka hoʻoholo ʻana i ka hewa like ʻole ma waena o ʻelua mau ʻili like ʻole (e like me nā helehelena alakaʻi a i ʻole nā ​​​​hiʻohiʻona hana kūʻē), me ka hoʻohana ʻana i nā mokulele kūʻē i hoʻoponopono ʻia o ka huinahā e like me nā kuhikuhi datum hiki ke hahai ʻia;
3. Ka hoʻoponopono pālahalaha: Hoʻohana ʻana i ka ʻili granite paʻa wela o ka huinaha i hoʻopau ʻia me ka optically—e like me ka hōʻoia ʻana i ka pālahalaha ≤0.5 μm ma luna o 100 mm (e like me JJG 700–2018)—ma ke ʻano he mokulele kuhikuhi pololei kiʻekiʻe no ke ana ʻana o ka pālahalaha ma o ka stylus profilometry a i ʻole nā ​​​​ʻano interferometric.
