ʻO nā ʻāpana wela kiʻekiʻe he mau ʻāpana paʻakikī me nā ʻāpana he nui e hiki ke hana ma lalo o ka ea hoʻoneʻe wela kiʻekiʻe a me nā kūlana corrosion kinoea.Loaʻa iā lākou ka ikaika wela maikaʻi, kūpaʻa wela, a me nā waiwai luhi wela.Hoʻohana nui ʻia nā alloys wela kiʻekiʻe i nā ʻenekini turbine mokulele a me nā ʻāpana pale wela o nā ʻenekini aerospace, ʻoi aku ka nui o nā paipu ahi, nā lau turbine, nā alakaʻi a me nā disc turbine, ʻo ia nā ʻāpana maʻamau o nā noi alloy kiʻekiʻe.Pono e hoʻomaopopo ʻia nā pilikia ma lalo i ka wā e hoʻomaʻamaʻa ai i nā mea ʻoki wili wili kiʻekiʻe.
No nā mea ʻoki wili wili kiʻekiʻe, koe wale no nā meaʻoki wili hope a me kekahi mau meaʻoki wili hope i hanaʻia me ka paʻakikī paʻakikī,ʻo ka hapa nui o nāʻanoʻoki wili i hanaʻia me ke kila kiʻekiʻe kiʻekiʻe.ʻOi aku ka maikaʻi o ka K10 a me ka K20 no nā mea paʻa paʻa i hoʻohana ʻia e like me nā wili hope a me nā wili hope, no ka mea, ʻoi aku ka paʻakikī o ka hopena a me ka luhi wela ma mua o K01.I ka wili ʻana i nā ʻāpana wela kiʻekiʻe, ʻo ka ʻoki ʻoki o ka mea paahana e ʻoi aku ka ʻoi a me ka pale ʻana i ka hopena, a ʻo ka nui o ka puʻu paʻa.No laila, hiki ke hoʻohana ʻia kahi ʻoki ʻoki milling angle nui.
I ka hoʻoheheʻe ʻana i nā ʻāpana wela kiʻekiʻe, kiʻekiʻe ka torque a me ka ikaika axial;Hoʻopili maʻalahi nā chips i ka bit drill, e paʻakikī ai ka wāwahi a wehe iā lākou;ʻO ka paʻakikī o ka hana, ʻaʻahu maʻalahi ma ke kihi o ka bit drill, a ʻo ka ʻoʻoleʻa ʻole o ka bit drill hiki ke hoʻoulu maʻalahi.No kēia kumu, pono e hoʻohana i ke kila kiʻekiʻe kiʻekiʻe, ultrafine grain hard alloy, a i ʻole carbide cemented e hana i nā ʻāpana drill.Eia kekahi, ʻo ia ka hoʻomaikaʻi ʻana i ka hoʻolālā drill bit e kū nei a i ʻole ka hoʻohana ʻana i nā bit drill bit kūikawā kūikawā.Hiki ke hoʻohana ʻia nā ʻāpana wiliwili paʻa paʻa S-type a me nā ʻāpana wili kāʻei ʻehā.ʻO ke ʻano o ka S-type hard alloy drill bits, ʻaʻohe o lākou ʻaoʻao ʻaoʻao a hiki ke hōʻemi i ka ikaika axial e 50%;He maikaʻi ke kihi mua o ke kikowaena wili, a ʻoi ka pahi;ʻO ka hoʻonui ʻana i ka mānoanoa o ke kumu drill e hoʻonui i ka ʻoʻoleʻa o ka drill bit;He ʻoki ʻoki pōʻai ʻo ia me ka puʻunaue kūpono o nā ʻāpana hoʻoneʻe chip;Elua puka ehu no ka hooluolu maalahi a me ka lubrication.Me ka hui pū ʻana o ke ʻano o ka ʻāwī a me nā ʻāpana nui, ʻo ke kāʻei kāʻei ʻehā e hoʻonui i ka manawa inertia o ka ʻāpana ʻāpana, e hoʻomaikaʻi i ka ikaika a me ka ʻoʻoleʻa o ka drill bit.Me kēia pahu drill, ma lalo o ka torque like, ʻoi aku ka liʻiliʻi o kāna hoʻololi torsional ma mua o ka deformation torsional o kahi drill bit maʻamau.
ʻOi aku ka paʻakikī ma nā ʻāpana wela wela, ʻoi aku ka paʻakikī o ka threading ma mua o ke kila maʻamau.Ma muli o ke kiʻekiʻe kiʻekiʻe o ka paʻi ʻana, ua maʻalahi ka "nahu" i ka lua i loko o ka lua wili, a hiki i ka tap ke haʻihaʻi a haki paha.ʻO ka mea paʻi i hoʻohanaʻia no nā'āpana wela wela e like me ka mea drill i hoʻohanaʻia no nā mea wela wela.ʻO ka maʻamau, hoʻohana ʻia nā loina paʻi kiʻekiʻe me ka wela wela i kahi hoʻonohonoho piha.No ka hoʻomaikaʻi ʻana i nā kūlana ʻoki o ka paipa, hiki ke liʻiliʻi iki ke anawaena o waho o ka paipa hope ma mua o ke anawaena maʻamau.ʻO ka nui o ke kihi cone ʻokiʻoki o ka tap e hoʻopili i ka mānoanoa o ka ʻoki ʻoki, torque, hana pono, maikaʻi o ka ʻili, a me ke ola lawelawe tap.E nānā pono i ke koho ʻana i ka nui kūpono.
