ʻO ka noi ʻana o ka Granite Measuring

Ke ana ʻenehana no ka granite - pololei i ka micron

Hoʻokō ka Granite i nā koi o ka ʻenehana ana i kēia manawa i ka ʻenehana mīkini.ʻO ka ʻike i ka hana ʻana i nā pahu ana a hoʻāʻo a me ka hoʻonohonoho ʻana i nā mīkini ana i hōʻike ʻia he ʻokoʻa nā pono o ka granite ma mua o nā mea kuʻuna.Penei ke kumu.

ʻO ka hoʻomohala ʻana o ka ʻenehana ana i nā makahiki i hala a me nā makahiki he mea hoihoi loa i kēia lā.I ka hoʻomakaʻana, ua lawa nāʻano ana maʻalahi e like me ke anaʻana i nā papa, nā paepae ana, nā pahu ho'āʻo, a me nā mea'ē aʻe, akā i ka lōʻihi o ka manawa, ua kiʻekiʻe a kiʻekiʻe nā koi no ka maikaʻi o ka huahana a me ke kaʻina hana.Hoʻoholo ʻia ka pololei o ke ana e ka geometry kumu o ka pepa i hoʻohana ʻia a me ka maopopo ʻole o ke ana ʻana o kēlā me kēia probe.Eia naʻe, ʻoi aku ka paʻakikī a me ka ikaika o nā hana ana, a pono e ʻoi aku ka pololei o nā hopena.Hōʻike kēia i ka wanaʻao o ka metrology coordinate spatial.

'O ka pololei, 'o ia ho'i ka ho'emi 'ana i ka mana'o
Aia ka mīkini ana hoʻonohonoho 3D i kahi ʻōnaehana hoʻonohonoho, kahi ʻōnaehana ana hoʻonā kiʻekiʻe, hoʻololi a i ʻole nā ​​mea ʻike ana, kahi ʻōnaehana loiloi a me nā lako polokalamu ana.No ka loaʻa ʻana o ka pololei ana kiʻekiʻe, pono e hoʻemi ʻia ke ana ʻana.

ʻO ka hewa ana ka ʻokoʻa ma waena o ka waiwai i hōʻike ʻia e ka mea ana a me ka waiwai kuhikuhi maoli o ka nui geometric (calibration standard).He 0.3+L/1000µm ka hewa ana ʻana o ka lōʻihi o nā mīkini ana hoʻonohonoho hou (CMMs).ʻO ka hoʻolālā ʻana o ka mea ana, probe, ana hoʻolālā, workpiece a me ka mea hoʻohana he mana koʻikoʻi i ka ʻae ʻana o ke ana lōʻihi.ʻO ka hoʻolālā mīkini ka mea maikaʻi loa a hoʻomau mau loa.

ʻO ka noi ʻana o ka granite i ka metrology kekahi o nā mea koʻikoʻi e pili ana i ka hoʻolālā ʻana o nā mīkini ana.He mea maikaʻi loa ka Granite no nā koi hou no ka mea e hoʻokō ana i ʻehā mau koi e hoʻopololei i nā hopena:

1. Kiʻekiʻe inherent paʻa
ʻO Granite he pōhaku lua pele i haku ʻia i ʻekolu mau mea nui: quartz, feldspar a me ka mica, i hana ʻia e ka crystallization o ka hoʻoheheʻe pōhaku i ka ʻōpala.
Ma hope o nā makahiki he mau makahiki o ka "ʻelemakule", he ʻano like ʻole ka granite a ʻaʻohe pilikia o loko.No ka laʻana, ʻo nā impalas ma kahi o 1.4 miliona mau makahiki.
He paʻakikī nui ka Granite: 6 ma ka pālākiō Mohs a me 10 ma ka pālākiō paʻakikī.
2. Kū'ē wela kiʻekiʻe
Ke hoʻohālikelike ʻia me nā mea metala, ʻoi aku ka haʻahaʻa o ka hoʻonui ʻana o ka granite (ma kahi o 5µm/m*K) a me ka helu hoʻonui haʻahaʻa haʻahaʻa (e like me ke kila α = 12µm/m*K).
ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o ka granite (3 W / m * K) e hōʻoia i ka pane lohi i ka piʻi ʻana o ka mahana i hoʻohālikelike ʻia me ke kila (42-50 W / m * K).
3. He hopena ho'ēmi haʻalulu maikaʻi loa
Ma muli o ke ʻano like ʻole, ʻaʻohe koʻikoʻi koena o ka granite.Hoʻemi kēia i ka haʻalulu.
4. Ekolu-coordinate alakai alahao me ka kiʻekiʻe precision
ʻO Granite, i hana ʻia me ka pōhaku paʻa maoli, hoʻohana ʻia ma ke ʻano he pā ana a hiki ke hana maikaʻi ʻia me nā mea hana daimana, ka hopena i nā ʻāpana mīkini me ka pololei kumu kiʻekiʻe.
Ma ka wili lima, hiki ke hoʻonui ʻia ka pololei o nā ala alakaʻi i ka pae micron.
I ka wā e wili ai, hiki ke noʻonoʻo ʻia nā deformation pili i ka ukana.
ʻO kēia ka hopena i kahi ʻili paʻa loa, e ʻae i ka hoʻohana ʻana i nā alakaʻi alakaʻi ea.ʻO nā alakaʻi alakaʻi ea he pololei loa ma muli o ke kūlana kiʻekiʻe o ka ʻili a me ka neʻe ʻana o ka lāʻau.

i ka hopena:
ʻO ka paʻa paʻa, ka pale wela, ka haʻalulu haʻalulu a me ka pololei o ke ala alakaʻi ʻehā mau hiʻohiʻona nui e hoʻolilo i ka granite i mea kūpono no CMM.Hoʻohana nui ʻia ka Granite i ka hana ʻana i nā pahu ana a me nā papa hoʻāʻo, a me nā CMM no ke ana ʻana i nā papa, nā papa ana a me nā lako ana.Hoʻohana ʻia ʻo Granite i nā ʻoihana ʻē aʻe, e like me nā mīkini mīkini, nā mīkini laser a me nā ʻōnaehana, nā mīkini micromachining, nā mīkini paʻi, nā mīkini optical, ka hui automation, ka semiconductor processing, etc.
