Ma nā kahua ʻokiʻoki e like me ka hana semiconductor a me ka hui ʻana i nā mea hana optical, ʻo ka ʻimi ʻana i ka sub-micron a i ʻole ka nanometer-level positioning pololei e ka multi-axis precision worktables pau ʻole. ʻO ka granite kiʻekiʻe kiʻekiʻe (me ka nui o ≥3100kg / m³) ke lilo nei i mea koʻikoʻi no ka hoʻomaikaʻi ʻana i ka hana o nā papa hana ma muli o kāna mau waiwai kino. ʻO kēia ka nānā ʻana i kāna mau pono hiki ʻole ke hoʻololi ʻia mai nā ana kumu ʻehā.
1. Paʻa maikaʻi: ʻO kahi "pale kūlohelohe" e hoʻopau i ke keakea haʻalulu
Ke holo ka papa hana axis multi-axis (me ka wikiwiki linear ma mua o 500mm/s) a i ʻole ma ka loulou multi-axis, hiki ke hana ʻia nā haʻalulu paʻakikī. Hoʻopili pili ʻia nā ʻāpana mineral o loko o ka granite kiʻekiʻe, me ke alapine kūlohelohe e like me ka 10-20Hz, a hiki ke hoʻopaʻa ʻia ma mua o 90% o ka ikehu haʻalulu o waho. I ke kaʻina hana hoʻopihapiha semiconductor chip, hiki iā ia ke hoʻomalu i ka hewa o ka neʻe ʻana o ka workbench i loko o ± 0.5μm, e pale ana i ka uea offset a i ʻole ka pōʻino chip i hana ʻia e ka haʻalulu. Ke hoʻohālikelike ʻia me nā mea hao kuʻuna, ʻekolu manawa ʻoi aku ka wikiwiki o ka vibration attenuation rate o ka granite, me ka hoʻomaikaʻi nui ʻana i ke kūlike o ka hana.
2. Thermal paʻa: Ka "Stabilizing heleuma" kū'ē i ka wela fluctuations
I loko o kahi kaʻina hana pololei, hiki i kahi hoʻololi wela o 0.1 ℃ ke hoʻololi i ka 0.1μm / m. ʻO ka coefficient o ka hoʻonui wela o ka granite kiʻekiʻe he (4-8) ×10⁻⁶/℃ wale nō, ʻo ia ka 1/6 o ka alumini alumini. I nā hiʻohiʻona kiʻekiʻe e like me ka wili ʻana i nā lens optical, ʻoiai inā e piʻi ka mahana o ka hale hana e ± 2 ℃, hiki i ke kumu granite ke mālama i ka pololei o ka micron-level positioning o nā mea nui o ka papa hana, me ka hōʻoia ʻana i ka hala o ka curvature lens ma lalo o 0.01D, ʻoi aku ma mua o ke kūlana ʻoihana.
3. Ultra-kiʻekiʻe rigidity: ʻO ka "Solid Foundation Stone" no ka lawe ʻana i nā ukana kaumaha
Hoʻolako pinepine ʻia nā papa hana multi-axis me nā mea koʻikoʻi e like me nā poʻo laser a me nā hoʻonohonoho probe (me ka ukana hoʻokahi-axis ma mua o 200kg). ʻO ka ikaika compressive o ka granite kiʻekiʻe kiʻekiʻe ʻo ≥200MPa, a hiki iā ia ke kūpaʻa i kahi ukana like ʻole ma luna o 1000kg / m² me ka ʻole o ka deformation mau. Ma hope o ka hoʻohana ʻana o kekahi ʻoihana aerospace i kēia mea, i ka wā i lawe ʻia ai kāna papa hana ʻelima-axis i ka ukana hana o 500kg, ua hoʻonui wale ʻia ka hewa Z-axis verticality e 0.3μm, e hōʻoia pono ana i ka pololei o ka hana ʻana o nā papa curved paʻakikī.
4. Ka lōʻihi lōʻihi: E ho'ēmi i ka nui o ke kumukūʻai o ke ola
ʻO ka paʻakikī Mohs o ka granite hiki i ka 6 a hiki i ka 7, a ʻoi aku kona kūpaʻa ʻana ma mua o ʻelima mau manawa ma mua o ke kila maʻamau. Ma kahi laina hana huahana 3C e hana ana no ka awelika o 16 mau hola i kēlā me kēia lā, hiki i ke kumu granite ke hoʻokō i ka hana mālama ʻole no 8 a 10 mau makahiki, ʻoiai ke hōʻike ʻia nei ke kumu hao i ka ʻaʻahu ma ke ala hoʻopili 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 acidic a me ka alkaline, e hāʻawi mau ana i kahi kuhikuhi hoʻonohonoho paʻa no nā mea kikoʻī e like me nā lula grating a me nā kaʻa laina.
Ka hopena: ʻO Granite High-density - ʻO ka "Hidden Champion" o ka Precision Manufacturing
Mai ke kūlana nanoscale a hiki i ka hana hana kaumaha, ke hoʻololi hou nei ka granite kiʻekiʻe i nā kūlana ʻenehana o nā papa hana precision multi-axis me kāna hana piha ʻole. No nā ʻoihana e ʻimi nei i ka pololei a me ka hilinaʻi loa, ʻo ke koho ʻana i nā kumu granite kiʻekiʻe (e like me nā huahana ZHHIMG® i hōʻoia ʻia e nā ʻōnaehana ISO ʻekolu) ʻaʻole ia he hōʻoia wale no ka hana ʻana i kēia manawa akā he waiwai hoʻolālā hoʻi i nā hoʻomaikaʻi kaʻina hana e hiki mai ana.
