Ua ʻike ʻia nā mea ʻokiʻoki o kēia wā ma mua o 100 mau makahiki o ka mōʻaukala hoʻomohala mai ke kila kila kila a hiki i ke kila kila kiʻekiʻe,carbide sima, mea hana seramikaamea hana paʻakikī. I ka hapalua ʻelua o ke kenekulia 18, ʻo ka mea paahana kumu ka nui o ke kila kila kalapona. No ka mea i ia manawa ua hoʻohana ʻia ʻo ia ka mea paʻakikī loa i hiki ke hana ʻia i mea hana ʻoki. Eia nō naʻe, ma muli o kona haʻahaʻa haʻahaʻa wela (ma lalo o 200 ° C), ʻo nā kila mea hana kalapona ka hemahema o ka hiki koke ʻana a me ka pōleʻele loa ma muli o ka ʻoki ʻana i ka wela i ka wā e ʻoki ai i nā wikiwiki kiʻekiʻe, a ua kaupalena ʻia ka pae ʻoki. No laila, ke kakali nei mākou i nā mea hana i hiki ke ʻoki ʻia i nā wikiwiki kiʻekiʻe. ʻO ka mea i puka mai e hōʻike i kēia manaʻo he kila kiʻekiʻe.
ʻO ke kila kiʻekiʻe, ka mea i kapa ʻia ʻo ke kila mua, ua hoʻomohala ʻia e nā ʻepekema ʻAmelika i ka makahiki 1898. ʻAʻole ʻoi aku ka liʻiliʻi o ke kalapona ma mua o ke kila kila, akā ua hoʻohui ʻia ka tungsten. Ma muli o ke kuleana o ka tungsten carbide paʻakikī, ʻaʻole i hoʻemi ʻia kona paʻakikī ma lalo o nā kūlana wela kiʻekiʻe, a no ka mea hiki ke ʻoki ʻia i ka wikiwiki i ʻoi aku ka kiʻekiʻe ma mua o ka wikiwiki o ka ʻoki ʻana o ke kila kila kila, ua kapa ʻia ʻo ia ke kila kiʻekiʻe. Mai 1900 ~ -1920, ʻike ʻia ke kila kiʻekiʻe me ka vanadium a me ka cobalt, a ua hoʻonui ʻia kona kūpaʻa wela i 500 ~ 600 °C. ʻO ka wikiwiki o kaʻokiʻana i ke kila a hiki i ka 30 ~ 40m / min, i hoʻonuiʻia e kokoke i 6 mau manawa. Mai ia manawa, me ka serialization o kona constituent elements, tungsten a me molybdenum high-speed steels ua hoʻokumu ʻia. Hoʻohana nui ʻia a hiki i kēia manawa. ʻO ka puka ʻana mai o ke kila kiʻekiʻe ka wikiwiki a
hoʻololi i ka ʻoki ʻana, hoʻomaikaʻi nui i ka huahana o ka ʻoki metala, a koi i ka hoʻololi piha ʻana i ke ʻano o ka mīkini mea hana e hoʻololi ai i nā koi hana o kēia mea hana hou. ʻO ka puka ʻana a me ka hoʻomohala hou ʻana o nā mīkini mīkini hou, ua alakaʻi ʻia i ka hoʻomohala ʻana i nā mea hana ʻoi aku ka maikaʻi, a ua hoʻoulu ʻia a hoʻomohala ʻia nā mea hana. Ma lalo o nā kūlana ʻenehana hana hou, loaʻa i nā mea hana kila kiʻekiʻe ka pilikia o ka palena ʻana i ka lōʻihi o ka mea hana ma muli o ka ʻoki ʻana i ka wela i ka wā e ʻoki ai i ka wikiwiki. Ke hiki i ka wikiwiki o ka ʻoki ʻana i 700 °C, ke kila kiʻekiʻe
ʻoki loa ka piko, a ma ka wikiwiki o ka ʻoki ʻana ma luna o kēia waiwai, hiki ʻole ke ʻoki. ʻO ka hopena, ua puka mai nā mea hana carbide e mālama pono ana i ka paʻakikī ma lalo o nā kūlana wela o ka ʻoki ʻana ma mua o ka mea i luna a hiki ke ʻoki ʻia i nā mahana ʻoki kiʻekiʻe.
Hiki keʻokiʻia nā mea palupalu me nā mea paʻakikī, a no kaʻokiʻana i nā mea paʻakikī, pono e hoʻohana i nā mea iʻoi aku ka paʻakikī ma mua o ia. ʻO ka mea paʻakikī loa ma ka Honua i kēia manawa he daimana. ʻOiai ua lōʻihi ka ʻike ʻia ʻana o nā daimana kūlohelohe ma ke ʻano, a he moʻolelo lōʻihi ko lākou hoʻohana ʻana iā lākou e like me nā mea ʻokiʻoki, ua kūleʻa maikaʻi ʻia nā daimana synthetic e like me ka hoʻomaka ʻana o nā 50s o ke kenekulia 20, akā ʻo ka hoʻohana maoli ʻana i nā daimana e hana ākea.mea hana ʻoki ʻoihanahe mau makahiki i hala iho nei.
Ma ka ʻaoʻao hoʻokahi, me ka hoʻomohala ʻana i ka ʻenehana ākea hou a me ka ʻenehana aerospace, ke hoʻohana nui ʻia nei ka hoʻohana ʻana i nā mea ʻenekinia hou, ʻoiai ʻo ka hoʻomaikaʻi ʻana i ke kila kiʻekiʻe, ka carbide cemented, amea paahana seramika houi ka ʻoki ʻana i nā mea hana maʻamau, ʻoki ʻia ka wikiwiki a me ka ʻoki ʻana i ka huahana i pālua ʻia a i ʻole i hoʻonui ʻia i nā manawa he nui, akā i ka wā e hoʻohana ai iā lākou e hoʻoponopono i nā mea i luna aʻe, haʻahaʻa loa ka lōʻihi o ka mea hana a me ka ʻoki ʻana, a paʻakikī ka maikaʻi o ka ʻoki. e hōʻoiaʻiʻo, i kekahi manawa ʻaʻole hiki ke hana, pono e hoʻohana i nā mea paahana ʻoi aku ka ʻoi aʻe o ka lole.
Ma ka ʻaoʻao ʻē aʻe, me ka ulu wikiwiki ʻana o nā mea houhana mīkinia me ka ʻoihana hana, ka hoʻohana nui ʻana o nā mea mīkini mīkini, nā kikowaena mīkini helu kamepiula (CNC), a me nā hale hana mīkini unmanned, i mea e hoʻomaikaʻi hou ai i ka pololei o ka hana, hoʻemi i ka manawa hoʻololi mea hana, a hoʻomaikaʻi i ka hana pono, ʻoi aku ka nui o nā koi wikiwiki. hana ʻia e loaʻa i nā mea paʻa paʻa paʻa. I kēia hihia, ua ulu wikiwiki nā mea hana daimana, a i ka manawa like, ka ulu ʻana omea paahana daimanaua paipai nui ia.
Mea paahana daimanaloaʻa i kahi ʻano o nā waiwai maikaʻi loa, me ka pololei o ka hana kiʻekiʻe, ka wikiwiki ʻoki wikiwiki a me ke ola lawelawe lōʻihi. No ka laʻana, hiki i ka hoʻohana ʻana i nā mea hana Compax (polycrystalline diamond composite sheet) ke hōʻoia i ka hana ʻana o nā ʻumi kaukani o nā ʻāpana apo piston alumini silicon aluminika a ʻaʻole i hoʻololi ʻia kā lākou mau ʻōlelo aʻoaʻo; ʻO ka mīkini mīkini mokulele alumina spars me nā Compax nui-diameter ʻokiʻoki hiki ke hōʻea i ka wikiwiki ʻoki a hiki i 3660m/min; ʻAʻole hiki ke hoʻohālikelike ʻia kēia me nā mea hana carbide.
ʻAʻole wale ia, ka hoʻohana ʻana omea paahana daimanahiki ke hoʻonui i ke kahua hana a hoʻololi i ka ʻenehana hana kuʻuna. I ka wā ma mua, hiki i ka hana aniani ke hoʻohana wale i ke kaʻina wili a me ka polishing, akā i kēia manawa ʻaʻole wale nā mea hana daimana kristal hoʻokahi wale nō, akā i kekahi mau mea hiki ke hoʻohana ʻia i nā mea hana PDC super-hard composite no ka ʻoki kokoke loa ʻana, e hoʻokō i ka huli ʻana. ma kahi o ka wili ana. Me ka noi omea hana paakiki loa, Ua puka mai kekahi mau manaʻo hou ma ke kahua o ka mīkini, e like me ka hoʻohana ʻana i nā mea hana PDC, ʻo ka hoʻololi ʻana i ka wikiwiki o ka huli ʻana ʻaʻole ia he mea paahana akā ʻo ka mīkini mīkini, a ke ʻoi aku ka wikiwiki o ka huli ʻana ma mua o kekahi wikiwiki, hana ka mea hana a me ka mea paahana. aole wela. He hohonu ka hopena o kēia mau manaʻo hoʻoheheʻe honua a hāʻawi i nā manaʻo palena ʻole no ka ʻoihana mīkini hou.
