ʻO ka mea maʻamau ke kiʻekiʻe ka paʻakikī o ka mea, ʻoi aku ka kiʻekiʻe o ka pale ʻana; ikaika flexural kiʻekiʻe, kiʻekiʻe hoʻi ka paʻakikī hopena. Akā ʻoi aku ka kiʻekiʻe o ka paʻakikī o ka mea, ʻoi aku ka haʻahaʻa o kona ikaika kulou a me ka paʻakikī. ʻO ke kila kiʻekiʻe ma muli o ka ikaika kuʻi kiʻekiʻe a me ka paʻakikī o ka hopena, a me ka machinability maikaʻi, ʻo ia nō ka mea paahana i hoʻohana nui ʻia, ukali ʻia e ka carbide.
He kūpono ka polycrystalline cubic boron nitride no ka ʻoki ʻana i ke kila paʻakikī paʻakikī a me ka hao hao, a me nā mea ʻē aʻe; He kūpono ke daimana polycrystalline no ka ʻokiʻoki ʻana i nā metala non-ferrous, a me nā alloys, plastics a me ke kila aniani, etc.; Hoʻohana wale ʻia ke kila kila kila a me ke kila kila kila ma ke ʻano he faila, nā niho pā a me nā paʻi a me nā mea hana ʻē aʻe.
Hoʻopili ʻia nā mea hoʻokomo i kuhikuhi ʻia ʻo Carbide me ka titanium carbide, titanium nitride, alumini oxide paʻa paʻa a i ʻole ka papa paʻakikī composite e ka waiho ʻana o ka mahu. Hoʻomohala ʻia ka waiho ʻana o ka mahu kino ʻaʻole wale no nā mea hana carbide akā no nā mea hana HSS e like me nā drills, hobs, tap a me nā mea ʻoki wili. ʻO ka paʻa paʻa paʻa e hana ma ke ʻano he pale i ka diffusion kemika a me ka hoʻololi ʻana i ka wela, e hoʻolōʻihi i ka ʻaʻahu o ka mea hana i ka wā e ʻoki ai, a me ka hoʻonui ʻana i ke ola o nā mea hoʻokomo i uhi ʻia ma kahi o 1 a 3 mau manawa a i ʻole ke hoʻohālikelike ʻia me nā mea i uhi ʻole ʻia.
Ma muli o ke kiʻekiʻe o ka wela, ke kiʻekiʻe kiʻekiʻe, ke kiʻekiʻe o ka wikiwiki, a me nā ʻāpana hana media corrosive fluid, ʻoi aku ka nui o ka hoʻohana ʻana i nā mea paʻakikī i ka mīkini, ʻoi aku ka kiʻekiʻe o ke kiʻekiʻe o ka automation o ka ʻoki ʻana a me ka mīkini a me nā koi pololei machining. I mea e hoʻololi ai i kēia kūlana, ʻo ke kuhikuhi o ka hoʻomohala ʻana i nā mea hana ʻo ia ka hoʻomohala ʻana a me ka hoʻohana ʻana i nā mea hana hou; ka hoʻomohala hou aʻe o ka ʻenehana hoʻoheheʻe ʻana o ka mea hana, i ka paʻakikī kiʻekiʻe a me ka ikaika kiʻekiʻe o ka substrate i waiho ʻia ma luna o ka uhi paʻakikī kiʻekiʻe, kahi hopena maikaʻi aʻe i ka kūʻē ʻana ma waena o ka paʻakikī o ka mea paahana a me ka ikaika o ka mea paahana; hoʻomohala hou aʻe o ke ʻano o ka mea hana indexable; e hoʻomaikaʻi i ka hana pono o ka mea hana e hōʻemi i ka ʻokoʻa i ka maikaʻi o ka huahana o ke kila manganese kiʻekiʻe he mea paʻakikī i ka mīkini. Nā koi kiʻekiʻe no nā mea paahana.
　　

ʻO ka ʻōlelo maʻamau, ʻo nā koi o ka mea hana ʻulaʻula ʻulaʻula, ke kūpaʻa maikaʻi ʻana, ka ikaika kiʻekiʻe, ka paʻakikī a me ka conductivity thermal. ʻO ka ʻoki ʻana i ke kila manganese kiʻekiʻe hiki ke koho i ka carbide, cermet e hana i nā mea hana ʻoki. I kēia manawa, ʻo ka mea hoʻohana maʻamau ka carbide cemented, nona ka YG ʻano o ka carbide cemented he kiʻekiʻe ka ikaika flexural a me ka paʻakikī o ka hopena (hoʻohālikelike ʻia me ke ʻano YT o ka carbide cemented), hiki ke hōʻemi i ka ʻoki ʻoki ʻana. I ka manawa like, ʻoi aku ka maikaʻi o ka conductivity thermal YG carbide, kahi e hoʻopau ai i ka hoʻopau ʻana o ka ʻoki ʻana i ka wela mai ka piko o ka mea hana, e hoʻemi ana i ka mahana o ka piko o ka mea hana a pale i ka piko o ka mea hana mai ka wela a me ka palupalu. ʻoi aku ka maikaʻi o ka wili ʻana o ka YG carbide, a hiki ke hoʻokala ʻia e hana i kahi ʻoi.
ʻO ka mea maʻamau, ʻo ka lōʻihi o ka paʻahana e pili ana i ka ʻulaʻula ʻulaʻula, ke kūpaʻa a me ka paʻakikī o ka hopena o ka mea paahana. no laila ua kūpono ia no ka roughing ma lalo o ke kūlana o ka hopena a me ka haʻalulu; ke loaʻa ka liʻiliʻi o ka cobalt, ʻoi aku ka paʻakikī, ka pale ʻana a me ke kūpaʻa wela, kūpono no ka hoʻopau mau ʻana.
