Ka wili ʻana
ʻO ka hoʻoheheʻe ʻana i ka wili ʻana no ka hoʻopau ʻana i ka mīkini (māhele ʻia ka mīkini i ka mīkini paʻakikī, ka hoʻopau ʻana i ka mīkini, ka mālama ʻana i ka wela a me nā ʻano hana ʻē aʻe), me ka liʻiliʻi o ka hana ʻana a me ka pololei kiʻekiʻe. Hoʻohana nui ia i ka ʻoihana hana mīkini. ʻO nā mea hao kalapona i hoʻomaʻamaʻa ʻia a kinai ʻia a me nā ʻāpana kila i hoʻopaʻa ʻia a kinai ʻia ka nui o nā māwae i hoʻonohonoho mau ʻia - nā māwae wili - ma ka ʻili e pili pono ana i ke kuhikuhi wili i ka wā wili. ʻAʻole pili wale ia i ke ʻano o nā ʻāpana, akā pili pono i ka maikaʻi o nā ʻāpana.
E pili ana i ke kaʻina ʻoki ʻana o ka ʻili mea hana me ka huila wili wili kiʻekiʻe a me nā mea hana abrasive ʻē aʻe. Hoʻohana ʻia ka wili e hana i nā ʻili cylindrical kūloko a me waho, nā ʻili conical a me nā mokulele o nā mea hana like ʻole, a me nā mea kūikawā a paʻakikī hoʻi e like me Ge Ban chips, threads, gears and splines.
Ma muli o ke kiʻekiʻe o ka paʻakikī o nā kīʻaha abrasive a me ka hoʻomaʻamaʻa ponoʻī ʻana i nā mea hana abrasive, hiki ke hoʻohana ʻia ka wili no ka hana ʻana i nā mea like ʻole, e like me ke kila paʻa, ke kila ikaika kiʻekiʻe, ka paʻa paʻa, ke aniani, ka seramika, ke kinikini a me nā metala paʻakikī ʻē aʻe. mea hao ole. ʻO ka wikiwiki wili e pili ana i ka laina laina o ka huila wili, ʻo ia ka 30 ~ 35 m / s. Inā ʻoi aku ia ma mua o 45 m/s, ua kapa ʻia ʻo ia ka wili kiʻekiʻe.
Hoʻohana pinepine ʻia ka wili no ka semi hoʻopau a me ka hoʻopau ʻana, a hiki i ka pololei ke hiki i IT8 ~ 5 a i ʻole ke kiʻekiʻe. ʻO ka roughness ili ka mea maʻamau i ka Ra1.25 ~ 0.16 μm, ka wili pololei iā Ra0.16 ~ 0.04 μm, ka ultra precision wili i ka Ra0.04 ~ 0.01 μm, a me ka wili aniani i Ra0.01 μm. ʻOi aku ka nui o ka mana kikoo o ka wili (a i ʻole ka hoʻohana ʻana i ka ikehu, ʻo ia hoʻi, ka ikehu i hoʻopau ʻia e ʻoki i ka mea hana i kēlā me kēia leo ʻāpana) ʻoi aku ka nui ma mua o ka ʻoki maʻamau, a ʻoi aku ka liʻiliʻi o ka neʻe ʻana o ka metala ma mua o ka ʻoki maʻamau.
No laila, ma mua o ka wili ʻana, hoʻoneʻe pinepine ʻia ka mea hana e nā ʻano ʻokiʻoki ʻē aʻe e hoʻoneʻe i ka ʻae mīkini o nā ʻāpana nui o Jiang Ali, e waiho wale ana i ka 0.1 ~ 1mm a i ʻole ka liʻiliʻi o ka ʻai ʻana. Me ka hoʻomohala ʻana i ka wili maikaʻi kiʻekiʻe, e like me ka creep feed grinding a me ka wikiwiki wikiwiki, hiki ke hoʻokaʻawale ʻia nā ʻāpana mai nā blanks. Hiki ke hoʻohana ʻia no ka mīkini paʻakikī ma ka wili ʻana, e like me ka wehe ʻana i ka mea holo a me ka piʻi ʻana o nā castings, ka uila o ka forgings a me ka ʻili o nā mea kila.
