ʻO nā papa ʻili Granite nā mea hana kuhikuhi kumu i ka metrology dimensional. Hana lākou ma ke ʻano he datum kino mua no ka nānā ʻana, ka calibration, a me ka hoʻonohonoho ʻana i ka hui ʻana.nā wahi hana kikoʻī kiʻekiʻeʻO nā ʻoihana e like me ka aerospace, ka hana semiconductor, nā ʻōnaehana optical, a me ka ʻenekinia mīkini hana holomua e hilinaʻi nei i kēia mau hale e mālama i ka pololei geometric ma nā pae micrometer a me sub-micrometer.

ʻAʻole e like me nā papa kuhikuhi metala, hāʻawi ka granite i kahi ʻano crystalline paʻa maoli me ke kaumaha kūloko haʻahaʻa loa, nā ʻano damping haʻalulu maikaʻi loa, a me ke kūpaʻa geometric lōʻihi. ʻO kēia mau waiwai e lilo ia i hoʻokahi o nā mea i hoʻohana nui ʻia no nā kumu metrology pololei ma ka honua holoʻokoʻa.

I loko o nā ʻōnaehana hana holomua, hoʻohana nā hui e like me ZHHIMG i ka granite ʻeleʻele kiʻekiʻe-density e hana i nā papa ʻili i hoʻolālā ʻia no nā wahi ana paʻa loa kahi e koʻikoʻi ai ka hana hou ʻana a me ka kaohi maopopo ʻole.

1. ʻEpekema Mea Ma hope o nā Papa ʻIli Granite

He pōhaku igneous ka Granite i haku ʻia me ka quartz, feldspar, a me ka mica. ʻAʻole ia he mea ulia ka kūpono no nā noi ʻenekinia precision akā ua loaʻa mai kona mau ʻano microstructural.

1.1 ʻAno Crystalline a me ke kūpaʻa

ʻO ka matrix kristal interlocking o ka granite e hāʻawi ana i:

• Ikaika compressive kiʻekiʻe
• ʻO ka hoʻololi elastic liʻiliʻi ma lalo o ke kaumaha
• Haʻahaʻa ke koʻikoʻi koena i hoʻohālikelike ʻia me nā metala i hoʻolei ʻia
• Kūlana kūpaʻa lōʻihi maikaʻi loa

ʻAʻole e like me ke kila a me ka alumini, ʻaʻole e loli ka granite i nā hoʻololi pae a i ʻole ka hoʻololi ʻana o ka plastic ma lalo o nā ukana metrology maʻamau, e kūpono ana no nā ʻili kuhikuhi.

1.2 Hana Wela

ʻO ke kūpaʻa wela kekahi o nā mea koʻikoʻi loa i nā ʻōnaehana metrology.

Nā waiwai maʻamau o ka granite ʻeleʻele kiʻekiʻe:

• Ka helu o ka hoʻonui wela: ~4–7 × 10⁻⁶ /°C
• ʻO ka inertia wela kiʻekiʻe
• Ka hoʻokele wela haʻahaʻa

ʻO ke ʻano kēia, hoʻolaha mālie nā gradients mahana ma o ka mea, e hōʻemi ana i ka distortion kūloko i ka wā o nā hana ana.

I ka hoʻohālikelike ʻana, hiki i nā hale kila ke hōʻike i nā waiwai hoʻonui wela a hiki i 12 × 10⁻⁶ /°C, e hoʻemi ana i ko lākou paʻa no nā noi kuhikuhi kikoʻī.

1.3 Nā ʻano Damping

Hōʻike ka Granite i ka damping haʻalulu kūlohelohe ma muli o kona ʻano mineral like ʻole. He mea nui kēia waiwai i nā wahi kahi:

• Aia nā haʻalulu mīkini waho
• Hana nā Mīkini Ana Hoʻohui (CMM)
• Hana ʻia ka interferometry laser

Hoʻopuehu ʻia ka ikehu haʻalulu ma o nā palena ʻano palaoa i loko ma mua o ka hoʻoili ʻia ʻana ma waena o ka hale.

2. Nā Kūlana Pololei no nā Papa ʻIli Granite

ʻAʻole nā ​​​​papa ʻili Granite he mau papa pālahalaha i manaʻo ʻole ʻia; hana ʻia a hōʻoia ʻia lākou ma lalo o nā kūlana metrology honua koʻikoʻi.

2.1 DIN 876 Kūlana (Kelemānia)

Ho'ākāka ke kūlana DIN 876 i nā māka hoʻomanawanui pālahalaha:

Hoʻohana pinepine ʻia ka pālahalaha me ka hoʻohana ʻana i nā pae uila, ka laser interferometry, a i ʻole nā ​​​​autocollimators.

2.2 ASME B89 (ʻAmelika Hui Pū ʻIa)

Ua wehewehe ʻo ASME B89:

• Nā koi kānalua o ke ana ʻana
• Nā kaʻina hana hoʻoponopono
• Ka hiki ke hahai ʻia i nā kūlana aupuni

Hoʻohana nui ʻia ia i nā ʻōnaehana hana aerospace a me nā pale kaua.

2.3 ISO 9001 / Nā ʻōnaehana maikaʻi e pili ana i ka ISO

ʻOiai ʻaʻole i wehewehe pololei ʻo ISO 9001 i nā hoʻomanawanui metrology, hoʻomalu ia i:

• Nā ʻōnaehana hoʻokele maikaʻi
• Ka hiki ke hahai ʻia ʻana o ka hoʻoponopono ʻana
• Nā koi kaohi hana

Pono nā mea hana e hana ana ma lalo o nā ʻōnaehana ISO e hōʻoia i ka hana hou ʻana a me nā kaulahao calibration i hoʻopaʻa ʻia.

3. ʻEnekinia Palahalaha a me nā ʻAno Ana

ʻO ka pālahalaha ke ana ho'ākāka o kahi papa ʻili. Eia nō naʻe, ʻaʻole ka pālahalaha he ana hoʻokahi kiko akā he waiwai geometric i loaʻa.

3.1 Nā ʻAno Ana

ʻO nā ʻano hana maʻamau:

• Nā pae ʻuhane uila (e laʻa, nā ʻōnaehana WYLER)
• Interferometry Laser (nā ʻōnaehana Renishaw)
• Nā Autocollimators
• Hoʻohālikelike mīkini me ka hoʻohana ʻana i nā kihi pololei haku

Hoʻokomo kēlā me kēia ʻano hana i nā ʻano like ʻole o ka maopopo ʻole.

3.2 Nā Kumu Hewa i ke Ana ʻana o ka Palahalaha

Nā mea koʻikoʻi o ka maopopo ʻole:

• Nā ʻano wela ma ka ʻili
• Ka hana hou ʻana o ka probe
• Haʻalulu liʻiliʻi i hoʻoulu ʻia e ka ea
• ʻOkoʻa ka lawelawe ʻana o ka mea hana
• Ka maopopo ʻole o ka hoʻoponopono ʻana o ka mea hana

I loko o nā keʻena hoʻokolohua kiʻekiʻe, hiki ke kaohi ʻia ka maopopo ʻole o ke ana holoʻokoʻa i loko o nā pae sub-micron.

3.3 Ke ʻano o ke kūpaʻa lōʻihi

ʻAʻole e like me nā papa metala, ʻaʻole hōʻike ka granite:

• Hoʻomaha i ke kaumaha
• Ka hoʻololi ʻana o ka kolo plastik
• Ka hoʻopilikia ʻia e ka luhi

ʻO kēia ka mea e kūpono ai nā papa ʻili granite no nā noi kuhikuhi lōʻihi me ka ʻole o ka mīkini hou pinepine ʻana.

4. Nā Hoʻohana ʻOihana o nā Papa ʻIli Granite

Hana ʻia nā papa ʻili Granite ma ke ʻano he mau mea kumu i nā ʻoihana ʻenehana kiʻekiʻe he nui.

4.1 Nā Mīkini Ana Hoʻohui (CMM)

Hoʻohana ʻia e like me:

• ʻIkepili kuhikuhi kumu
• Kahua hoʻoponopono mīkini
• Kumu nānā ʻana i nā mea hana

4.2 Nā Lako Hana Semiconductor

Aia nā noi:

• Nā ʻōnaehana hoʻonohonoho wafer
• Nā pae hoʻonoho Lithography
• Nā kahua metrology nānā

4.3 Ka Hoʻoponopono ʻana i nā Mea Hana Mīkini Pololei

Hoʻohana ʻia no:

• Hoʻonohonoho ʻana o ka mīkini CNC
• Ka hoʻoponopono alakaʻi laina
• Ka hōʻoia ʻana o ka holo ʻana o ka spindle

4.4 Nā ʻōnaehana Optical a me Laser

Kākoʻo nā kumu Granite:

• Nā interferometer laser
• Nā noho hoʻonohonoho optical
• Nā ʻōnaehana hōʻuluʻulu Photonics

5. Granite vs Nā Mea Hana ʻē aʻe

ʻO kahi hoʻoholo koʻikoʻi o ka ʻenekinia ʻo ke koho ʻana i nā mea no nā kumu kuhikuhi.

ʻOi aku ka maikaʻi o ka Granite ma mua o nā koho metala i nā wahi metrology.

6. Nā Manaʻo Hana Hana ʻOihana

Pono nā papa ʻili granite kiʻekiʻe i nā wahi hana i kāohi ʻia:

• Nā kaʻina hana lapping pololei
• Ka ʻoki ʻana a me ka wili ʻana i nā pae he nui
• Ka mana o ka mahana o ke kaiapuni (20°C ±1°C maʻamau)
• Nā pōʻaiapuni hoʻopaʻa hoʻomaha kaumaha

Hoʻohui nā mea hana holomua e like me ZHHIMG i nā ʻōnaehana mīkini nui i hiki ke hana i nā papa e ʻoi aku ana i kekahi mau mika ka lōʻihi me ka mālama ʻana i ka kaohi pālahalaha micron-level.

Hopena

ʻO nā papa ʻili Granite ke kumu o ka metrology pololei o kēia au ma muli o ko lākou hui kūikawā o ke kūpaʻa mechanical, ka neutrality thermal, a me nā ʻano damping haʻalulu. Ke hui pū ʻia me ka pili pono ʻana i nā kūlana honua e like me DIN 876 a me ASME B89, hāʻawi nā ʻōnaehana i hoʻokumu ʻia i ka granite i ke kahua no ka ʻōnaehana ana hilinaʻi, hiki ke hana hou ʻia, a hiki ke hahai ʻia.

I ka hoʻomau ʻana o ka pololei o ka hana ʻana i nā hoʻomanawanui nanometer-scale, e mau ana ka granite i mea hiki ke koʻikoʻi i ka ʻōnaehana metrology honua.
