Ma nā kahua ʻoi loa e like me ka hana semiconductor a me ka ʻākoakoa ʻana o nā mea hana optical, ʻaʻohe palena o ka ʻimi ʻana i ka pololei o ke kūlana sub-micron a i ʻole nanometer-level e nā papa hana pololei multi-axis. Ke lilo nei ka granite kiʻekiʻe-density (me ka density o ≥3100kg/m³) i mea nui no ka hoʻomaikaʻi ʻana i ka hana o nā papa hana ma muli o kona mau waiwai kino kū hoʻokahi. Eia ka loiloi o kona mau pono hiki ʻole ke hoʻololi ʻia mai nā ana ʻehā.
1. Paʻa maikaʻi loa: He "pale kūlohelohe" e kāohi i ka hoʻopilikia haʻalulu
Ke neʻe wikiwiki nei kahi papa hana multi-axis (me ka wikiwiki linear ma mua o 500mm/s) a i ʻole ma ka linkage multi-axis, hiki ke loaʻa nā haʻalulu paʻakikī. Hoʻopili pili ʻia nā ʻāpana mineral kūloko o ka granite kiʻekiʻe, me ka alapine kūlohelohe e like me 10-20Hz, a hiki ke omo ma mua o 90% o ka ikehu haʻalulu waho. I ke kaʻina hana hoʻopili ʻāpana semiconductor, hiki iā ia ke kaohi i ka hewa neʻe ʻana o ka papa hana i loko o ± 0.5μm, e pale ana i ka offset uea a i ʻole ka hōʻino ʻana o ka chip i hoʻokumu ʻia e ka haʻalulu. Ke hoʻohālikelike ʻia me nā mea hao hao kuʻuna, ʻekolu manawa wikiwiki ka wikiwiki o ka haʻalulu o ka granite, e hoʻomaikaʻi nui ana i ke kūlike o ka hana ʻana.
2. Paʻa wela: ʻO ka "heleuma hoʻopaʻa" e kūʻē i nā loli o ka mahana
I loko o kahi ʻano hana kikoʻī, hiki i ka loli ʻana o ka mahana o 0.1 ℃ ke hana i kahi deformation mea o 0.1 μm/m. ʻO ke coefficient o ka hoʻonui ʻana o ka thermal o ka granite kiʻekiʻe-density he (4-8) ×10⁻⁶/℃ wale nō, ʻo ia hoʻi ma kahi o 1/6 o ka alumini alloy. I nā hiʻohiʻona kikoʻī kiʻekiʻe e like me ka wili ʻana o ka lens optical, ʻoiai inā loli ka mahana o ka hale hana ma ±2 ℃, hiki nō i ke kumu granite ke mālama i ka pololei o ke kūlana micron-level o nā ʻāpana koʻikoʻi o ka workbench, e hōʻoiaʻiʻo ana ʻo ka hewa curvature lens he emi ma mua o 0.01D, ʻoi aku ka maikaʻi ma mua o ke kūlana ʻoihana.
3. ʻO ke kūpaʻa kiʻekiʻe loa: ʻO ka "Solid Foundation Stone" no ka hāpai ʻana i nā ukana kaumaha
Hoʻolako pinepine ʻia nā papa hana multi-axis me nā ʻāpana kaumaha e like me nā poʻo laser a me nā ʻāpana probe (me ka ukana hoʻokahi-axis e ʻoi aku ana ma mua o 200kg). ʻO ka ikaika compressive o ka granite kiʻekiʻe-density he ≥200MPa, a hiki iā ia ke kū i kahi ukana like ma luna o 1000kg/m² me ka ʻole o ka deformation mau loa. Ma hope o ka lawe ʻana o kekahi ʻoihana aerospace i kēia mea, i ka wā i lawe ai kāna papa hana ʻelima-axis i kahi ukana hana o 500kg, ua hoʻonui wale ʻia ka hewa verticality Z-axis e 0.3μm, e hōʻoia pono ana i ka pololei o ka hana ʻana o nā ʻili piʻo paʻakikī.
4. Ka lōʻihi o ke kūpaʻa: E hōʻemi i ke kumukūʻai holoʻokoʻa o ke ola
ʻO ka paʻakikī Mohs o ka granite e hiki aku i ka 6 a 7, a ʻoi aku kona kūpaʻa ʻana i ka ʻaʻahu ma mua o ʻelima mau manawa o ke kila maʻamau. Ma kahi laina hana huahana 3C e hana ana no ka awelika o 16 mau hola i ka lā, hiki i ke kumu granite ke hoʻokō i ka hana mālama ʻole no 8 a 10 mau makahiki, ʻoiai ke kumu hao i hoʻolei ʻia e hōʻike ana i ka ʻaʻahu ma ka ʻili pili o ke alahao alakaʻi (hohonu > 5μm) ma hope o 3 mau makahiki. Eia kekahi, ʻo kona inertness kemika e hiki ai iā ia ke mālama i ka ʻili o Ra≤0.2μm i nā wahi waikawa a me alkaline, e hāʻawi mau ana i kahi kuhikuhi hoʻonohonoho paʻa no nā ʻāpana kikoʻī e like me nā lula grating a me nā motika linear.
Hopena: Granite kiʻekiʻe - ʻO ka "Poʻokela Huna" o ka Hana ʻana i ka Precision
Mai ke kūlana nanoscale a i ka hana kaumaha, ke hoʻololi nei ka granite kiʻekiʻe i nā kūlana loea o nā papa hana pololei multi-axis me kāna hana piha ʻole. No nā ʻoihana e alualu ana i ka pololei loa a me ka hilinaʻi, ʻo ke koho ʻana i nā kumu granite kiʻekiʻe (e like me nā huahana ZHHIMG® i hōʻoia ʻia e nā ʻōnaehana ISO ʻekolu) ʻaʻole wale ia he hōʻoia no ka hana o kēia manawa akā he hoʻopukapuka kālā hoʻolālā hoʻi i nā hoʻonui kaʻina hana e hiki mai ana.
