ʻO nā mea maikaʻi o ka hoʻohana ʻana i nā paepae precision granite i nā mīkini ana ʻekolu-coordinate.

Ma ke kahua o ka hana ʻoihana, ʻo ka mīkini ana ʻekolu-coordinate (CMM) kahi mea nui no ka hoʻokō ʻana i ka nānā ʻana o ka dimensional pololei a me ke ʻano a me ka loiloi ʻana i ke kūlana, a ʻo kona pololei ana e pili pono i ka maikaʻi o ka huahana. ʻO nā paepae kiko o Granite, me kā lākou hana koʻikoʻi, ua lilo i kumu koho kūpono no nā mīkini ana ʻekolu-coordinate, e hāʻawi ana i nā hōʻoia hilinaʻi no ka ʻike kiʻekiʻe. ʻ
1. Ultra-kiʻekiʻe precision a me ka paʻa
Loaʻa i nā paepae kiko o Granite ke kūpaʻa o ka nui a me ka helu haʻahaʻa loa o ka hoʻonui wela, ʻo ia wale nō (4-8) ×10⁻⁶/℃. I loko o ka ʻenehana paʻakikī a hoʻololi ʻia, ʻoiai inā e loli ana ka mahana, ʻaʻole hiki ke hoʻololi ʻia ka nui o ka paepae, me ka pale ʻana i nā hewa ana i hana ʻia e ka deformation thermal. I kēia manawa, ʻoʻoleʻa ke ʻano aniani o loko o ka granite. Ma hope o nā piliona makahiki o ka hana geological, ua hoʻopau maoli ʻia ke koʻikoʻi kūloko, a ʻaʻohe deformation ʻelemakule. Mālama kēia i ka paʻa lōʻihi o ka kuhikuhi ana a mālama i ka pololei o ka hoʻonohonoho ʻana a me ka hoʻihoʻi ʻana i ka pololei o ka hoʻonohonoho ʻana o ka mīkini ana ʻekolu-coordinate ma kahi kiʻekiʻe i nā manawa a pau. ʻ

ʻO ka lua, maikaʻi ka anti-vibration a me ka hana damping
ʻO ka haʻalulu i hana ʻia e ka hana ʻana o nā mīkini mīkini a me ka hoʻomaka ʻana a me ka hoʻōki ʻana o nā mea hana i loko o ka hale hana hana hiki ke hoʻopilikia i ka ʻike pololei ʻana o ka mīkini ana ʻekolu-coordinate. Loaʻa i ka Granite nā waiwai damping maikaʻi loa, me ka ratio damping a hiki i ka 0.05-0.1, hiki ke hoʻopau koke i ka ikehu o nā haʻalulu o waho. Ke hoʻouna ʻia nā haʻalulu o waho i ka paepae, hiki i ka granite ke hoʻopau i nā haʻalulu i ka manawa pōkole, e hōʻemi i ka hoʻopili ʻana i ka haʻalulu i ka wā o ke ana ʻana, e hōʻoia i ka pololei o ka pilina ma waena o ke ana ʻana a me ka ʻili o ka mea hana, a me ka hana ʻana i ka ʻikepili ana i ʻoi aku ka pololei a hilinaʻi. ʻ
ʻekolu. ʻO ka paʻakikī kiʻekiʻe a me ke kūpaʻa ʻaʻahu
ʻO ka Granite ka paʻakikī o 6 a 7 ma ka pālākiō Mohs, kahi mānoanoa mai 2.7 a 3.1g/cm³, a me ke kūpaʻa ʻana o ka ʻili. I ka wā lōʻihi o ka hoʻohana ʻana i ka mīkini ana ʻekolu, ʻo ka hoʻouka pinepine ʻana a me ka wehe ʻana i nā mea hana a me ka neʻe ʻana o ke ana ʻana, ʻaʻole hiki ke hoʻohana i ka ʻaʻahu ma ka ʻili o ka paepae granite. ʻOiai ma hope o nā makahiki o ka hoʻohana ʻana, hiki i ka ʻili o ka paepae ke mālama i ka palahalaha maikaʻi a me ka maʻalahi, e hoʻolōʻihi i ke ola lawelawe kiʻekiʻe o ka mīkini ana ʻekolu-coordinate a me ka hōʻemi ʻana i nā kumukūʻai mālama pono. ʻ
ʻEhā, paʻa kemika ikaika
I loko o nā kaiapuni hana ʻenehana, loaʻa pinepine nā mea kemika e like me ka ʻoki ʻana i nā wai a me nā aila lubricating, a hiki i kekahi ke hele pū me nā kinoea corrosive. Loaʻa i ka Granite nā waiwai kemika paʻa, kahi ākea pH tolerance range (1-14), hiki ke pale i ka hoʻoheheʻe ʻana o nā mea kemika maʻamau, a ʻaʻole hiki ke ʻā i ka ʻōpala a i ʻole ka pala. ʻAʻole wale kēia hiʻohiʻona e pale i ka paepae ponoʻī akā e hōʻoiaʻiʻo i kahi kaiapuni hana maʻemaʻe no ka mīkini ana ʻekolu-coordinate, e pale ana i ka pololei o ke ana ʻana a me ke ola lawelawe ʻana o nā lako e hoʻopilikia ʻia e ka pollution kemika. ʻ
ʻO nā paepae kikoʻī Granite, me kā lākou pono o ka pololei kiʻekiʻe, ke kūpaʻa kiʻekiʻe, ke kūpaʻa haʻalulu, ke kūpaʻa a me ke kūpaʻa kemika, e hāʻawi i kahi kumu paʻa no ka ʻike pololei ʻana o nā mīkini ana ʻekolu-coordinate a pāʻani i kahi mea hiki ʻole ke hoʻololi ʻia i ka loulou kaohi o ka hana hana precision hou.
