ʻO ka mea paahana Superhard e pili ana i ka mea paʻakikī hiki ke hoʻohana ʻia ma ke ʻano he mea ʻoki. I kēia manawa, hiki ke hoʻokaʻawale ʻia i ʻelua mau ʻāpana: ʻokiʻoki daimana mea hana a me cubic boron nitride mea ʻoki mea hana. ʻElima ʻano nui o nā mea hou i hoʻohana ʻia a i ʻole e hoʻāʻo ʻia
(1) Kūlohelohe a me ka hoʻoheheʻe ʻana i ke daimana kristal nui hoʻokahi
(2) Poly daimana (PCD) a me poly daimana composite blade (PDC)
(3) CVD daimana
(4) Polycrystal cubic boron ammonia; (PCBN)
(5) CVD cubic boron amonia uhi
1, kūlohelohe a me ka synthetic nui hoʻokahi aniani daimana
ʻO ka daimana maoli he ʻano aniani aniani me ka ʻole o ka palena o loko, i hiki ai i ka ʻaoʻao o ka mea hana ke hiki i ke ʻano o ka atomic smoothness a me ka ʻoi, me ka ikaika ʻoki ʻoki, kiʻekiʻe kiʻekiʻe a me ka ikaika ʻoki liʻiliʻi. ʻO ka paʻakikī, ke kūpaʻa a me ka pale ʻana a me ke kūpaʻa kemika o ke daimana maoli e hōʻoia i ka lōʻihi o ke ola o ka mea hana, hiki ke hōʻoia i ka ʻoki maʻamau lōʻihi, a hoʻemi i ka hopena o ka mea hana i ka pololei o nā ʻāpana i hana ʻia, hiki i kāna conductivity thermal kiʻekiʻe ke hōʻemi i ka ʻoki ʻana i ka mahana a me ka deformation thermal o nā ʻāpana. Hiki i nā hiʻohiʻona maikaʻi o ka daimana kristal nui maoli ke hoʻokō i ka hapa nui o nā koi o ka precision a me ka ʻoki ʻoki ultra-precision no nā mea hana. ʻOiai he pipiʻi kona kumukūʻai, ua ʻike ʻia ʻo ia ka precision kūpono a me ka ultra precision mea paahana, hiki ke hoʻohana nui ʻia i ka hoʻoponopono ʻana i nā reactors nuklea a me nā ʻenehana kiʻekiʻe ʻē aʻe i ke kahua o nā aniani, missiles a me nā rockets, computer hard disk substrate, accelerator electron gun super precision machining, a me nā ʻāpana wati kuʻuna, nā mea nani, nā peni, nā ʻāpana metala hoʻonaninani precision processing, etc. scalpel, nā lāʻau ola kino lahilahi a me nā mea lapaʻau ʻē aʻe. ʻO ka hoʻomohala ʻana i kēia manawa o ka ʻenehana kiʻekiʻe a me ka ʻenehana kiʻekiʻe e hiki ai ke hoʻomākaukau i kahi daimana kristal nui me kahi nui. ʻO ka maikaʻi o kēia mea mea hana daimana kona nui maikaʻi, ke ʻano a me ka hana o ka kūlike, ʻaʻole i loaʻa i nā huahana daimana maoli. Ma muli o ka liʻiliʻi o ka lako daimana kūlohelohe nui, kumu kūʻai pipiʻi, synthetic nui particle one crystal diamond tool tool in ultra-precision cutting processing as a natural large single crystal diamond substitute, kāna noi e hoʻomohala wikiwiki ʻia.
2, polycrystal diamond (PCD) a me polycrystal diamond composite blade (PDC) i hoʻohālikelike ʻia me ka daimana aniani nui hoʻokahi ma ke ʻano he mea paahana o ka polycrystal daimana (PCD) a me ka polycrystal diamond composite blade (PDC) i kēia mau mea maikaʻi: (1) ka palaoa disordered hoʻonohonoho, isotropic, ʻaʻohe cleavage surface. No laila, ʻaʻole ia e like me ke daimana aniani nui hoʻokahi ma luna o ka ikaika o ka ʻili aniani, paʻakikī
A he ʻokoʻa loa ka pale ʻana o ka ʻaʻahu, a ma muli o ke ʻano o ka cleavage surface a brittle.
(2) he ikaika kiʻekiʻe, ʻoi aku ka PDC mea paahana ma muli o ke kākoʻo o ka carbide matrix a he kiʻekiʻe ka hopena o ka hopena, ʻo ka hopena e hoʻopuka wale i ka palaoa liʻiliʻi, ʻaʻole like me ka hiolo nui o ka daimana kristal hoʻokahi, no laila me ka PCD a i ʻole ka PDC mea hana ʻaʻole hiki ke hoʻohana wale ʻia no ka ʻoki pololei a me ka hapalua maʻamau machining. Akā hiki ke hoʻohana ʻia ma ke ʻano he nui o ka mīkini paʻakikī a me ka hana intermittent (e like me ka milling, etc.), ka mea e hoʻonui nui ai i ka hoʻohana ʻana i nā mea hana daimana.
(3) Hiki ke hoʻomākaukau ʻia nā mea hana PDC nui e hoʻokō i nā pono o nā mea hana mīkini nui e like me ka ʻoki ʻoki.
(4) Hiki ke hana ʻia nā ʻano kikoʻī e hoʻokō i nā pono o ka hana like ʻole. Ma muli o ka hoʻomaikaʻi ʻana i ka billet hāmeʻa PDC a me ka ʻenehana hana e like me ka uila uila, ka ʻenehana ʻokiʻoki laser, triangle, herringbone, gables a me nā billet blade kūikawā kūikawā hiki ke hana a hana ʻia. I mea e hoʻokō ai i nā pono o nā mea hana ʻoki kūikawā, hiki ke hoʻolālā ʻia e like me ke kāwili ʻana, sandwich a me ka roll PDC tool billet.
(5) Hiki ke hoʻolālā a wānana paha ka hana o ka huahana, a hāʻawi ʻia ka huahana i nā ʻano kūpono e hoʻololi ai i kāna hoʻohana kikoʻī. No ka laʻana, hiki i ke koho ʻana i nā mea paahana PDC maikaʻi ke hoʻomaikaʻi i ka maikaʻi o ka lihi o ka mea hana; Hiki ke hoʻonui i ka paʻa o ka mea hana PDC coarse-grained.
I ka hopena, me ka hoʻomohala ʻana o nā mea hana PCD a me PDC, ua hoʻonui wikiwiki ʻia ka noi ʻana o ka mea hana PCD a me PDC i nā hana hana he nui.
Hoʻohana nui ʻia ka ʻoihana i nā metala non-ferrous (alumini, aluminika, keleawe, keleawe keleawe, magnesium alloy, zinc alloy, etc.), carbide, ceramics, non-metallic material (plastic, hard rubber, carbon rods, wood, cement products, etc.), composite material (e like me ka fiber reinforced plastic CFRP, metala matrix composite a me ka MMC o ka hana ʻana i ka ʻoihana ʻoihana kiʻekiʻe. carbide.
