ʻO ka huli ʻana, ka wili ʻana, ka hoʻolālā ʻana, ka wili ʻana, ka ʻeli ʻana, ka ʻoluʻolu, ka pololei kiʻekiʻe loa o kēia mau mīkini mīkini a me nā pae hoʻomanawanui e hiki ke hoʻokō i nā ʻano hana like ʻole.
Huli
ʻO ke kaʻina ʻokiʻoki kahi e hoʻohuli ai ka mea hana a neʻe ka mea hoʻohuli i kahi laina pololei a i ʻole ka pihi ma ka mokulele. Hoʻohana pinepine ʻia ka huli ʻana ma luna o kahi lathe, kahi i hoʻohana ʻia no ka hoʻoponopono ʻana i nā ʻili o loko a me waho o ka cylindrical surfaces, nā maka hope, nā conical surfaces, ka hana ʻana i nā ʻili a me nā kaula o nā mea hana.
ʻO ka pololei o ka huli ʻana he IT8-IT7, a ʻo ka roughness ʻili he 1.6 ~ 0.8 μm.
1) E hoʻohana ka hoʻohuli ʻino i ka hohonu o ka ʻoki ʻana a me ka nui o ka hānai nui e hoʻomaikaʻi i ka hoʻololi ʻana me ka ʻole o ka hōʻemi ʻana i ka wikiwiki o ka ʻoki ʻana, akā hiki i ka pololei o ka mīkini ke hiki i IT11 a ʻo ka ʻili o ka ʻili he R α 20 ~ 10 μm.
2) E ʻae ʻia ka wikiwiki kiʻekiʻe a me ka helu hānai liʻiliʻi a me ka hohonu o ka ʻoki ʻana e like me ka hiki no ka huli ʻana a me ka huli hope. Hiki i ka pololei machining ke hiki i IT10 ~ IT7, a ʻo ka ʻili o ka ʻili he R α 10 ~ 0.16 μm.
3) Ka wikiwiki kiʻekiʻeka huli pono ʻana o nā ʻāpana metala nonferrousme ka daimana huli mea hana finely polie ma kiʻekiʻe-pololei lathe hiki ke hana i ka machining pololei hiki IT7 ~ IT5, a me ka roughness ili he R α 0.04 ~ 0.01 μm. Kapa ʻia kēia ʻano huli ʻana he "mirror turning".
Milling
ʻO ka Milling e pili ana i ka hoʻohana ʻana i nā hāmeʻa hoʻololi ʻana i nā ʻaoʻao he nui e ʻoki i nā mea hana, ʻo ia ke ʻano hana ʻoi loa. He kūpono ia no ka mokulele machining, groove, nā ʻano hana like ʻole (e like me ka spline, gear a me ke kaula) a me ka ʻili kūikawā o ka make. E like me ka like a i ʻole ka ʻaoʻao ʻē aʻe o ka wikiwiki o ka neʻe ʻana a me ke kuhikuhi ʻana o ka mea hana i ka wā wili, hiki ke hoʻokaʻawale ʻia i ka wili i mua a me ka wili hoʻohuli.
ʻO ka pololei machining o ka milling hiki ke hōʻea i IT8 ~ IT7, a ʻo ka roughness ʻili he 6.3 ~ 1.6 μm.
1) ʻO ka pololei o ka mīkini ʻana i ka wā wili liʻiliʻi ʻo IT11 ~ IT13, a ʻo ka roughness ʻili he 5 ~ 20 μm.
2) ʻO ka pololei o ka mīkini IT8 ~ IT11 a me ka ʻeleʻele o ka ʻili 2.5 ~ 10 i ka semi precision milling μm.
3) ʻO ka pololei o ka mīkini i ka wā wili pololei ʻo IT16 ~ IT8, a ʻo ka ʻili o ka ʻili he 0.63 ~ 5 μm.
Hoʻolālā
ʻO ka hoʻolālā kahi ʻano ʻokiʻoki e hoʻohana ana i kahi planer e hana i ka neʻe ʻana o ka laina laina ma luna o ka mea hana, kahi i hoʻohana nui ʻia no ka hana contour o nā ʻāpana.
ʻO ka pololei machining o ka hoʻolālā hiki ke hōʻea i IT9 ~ IT7, a ʻo ka ʻili o ka ʻili he Ra6.3 ~ 1.6 μm.
1) Hiki ke hōʻea i ka pololei machining ʻo IT12 ~ IT11, a ʻo ka roughness ʻili he 25 ~ 12.5 μm.
2) Hiki ke hōʻea i ka pololei machining semi hoʻopau i ka IT10 ~ IT9, a ʻo ka roughness o ka ʻili he 6.2 ~ 3.2 μm.
3) Hiki i ka pololei o ka hoʻolālā hoʻopau ke hiki i IT8 ~ IT7, a ʻo ka ʻili o ka ʻili he 3.2 ~ 1.6 μm.
wili
ʻO ka wili e pili ana i ke kaʻina hana o ka wehe ʻana i nā mea keu mai ka mea hana me nā mea hana abrasive a me nā mea abrasive. No ka hoʻopau ʻana a hoʻohana nui ʻia i ka ʻoihana hana mīkini.
Hoʻohana pinepine ʻia ka wili no ka semi hoʻopau ʻana a me ka hoʻopau ʻana, me ka pololei o IT8 ~ IT5 a i ʻole ke kiʻekiʻe aʻe, a ʻo ka roughness o ka ʻili he 1.25 ~ 0.16 μm.
1) ʻO 0.16 ~ 0.04 μm ka roughness o ka wili pololei.
2) ʻO 0.04-0.01 μm ka nui o ka wili ʻana o ka ʻili.
3) Hiki i ka roughness ili o ka wili aniani ke hiki i ka 0.01 μM ma lalo.
Ka wili ʻana
ʻO ka wili ʻana ke ʻano kumu o ka hana ʻana i nā lua. Hoʻohana pinepine ʻia ka wili ʻana ma nā mīkini wili a me nā lathes, a i ʻole ma nā mīkini hoʻolulu a i ʻole nā mīkini wili.
He haʻahaʻa haʻahaʻa ka pololei o ka mīkini hana ʻana, hiki i ka IT10, a ʻo ka roughness o ka ʻili he 12.5 ~ 6.3 μm. Ma hope o ka wili ʻana, hoʻohana pinepine ʻia ka reaming a me ka reaming no ka semi hoʻopau a hoʻopau.
Luuluu
He ʻano hana ʻoki anawaena o loko e hoʻohana ana i kahi mea hana e hoʻonui ai i ka lua a i ʻole ka ʻāpana pōʻai ʻē aʻe. ʻO ka laulā o kāna noi mai ka mīkini semi rough a hiki i ka hoʻopau ʻana. ʻO ka mea hana i hoʻohana pinepine ʻia he mea hana hoʻoluʻu hoʻokahi ʻaoʻao (kapa ʻia ʻo boring bar).
1) Hiki ke hōʻea i ka pololei o nā mea kila i IT9 ~ IT7, a ʻo ka ʻili o ka ʻili he 2.5 ~ 0.16 μm.
2) ʻO ka pololei o ka mīkini hana ʻana o ka hōʻoluʻolu pololei hiki ke hiki i IT7 ~ IT6, a ʻo ka ʻili o ka ʻili he 0.63 ~ 0.08 μm.
Nānā:Kiekie precision MīkiniHoʻohana nui ʻia e ʻike i ka maikaʻi o nā huahana, a he huaʻōlelo i hoʻohana ʻia e loiloi i nā ʻāpana geometric o nā ʻili mīkini. ʻO ka maʻamau no ke ana ʻana i ka pololei machining ʻo ia ka māka hoʻomanawanui. Aia he 20 mau maʻamau mai IT01, IT0, IT1, IT2, IT3 a hiki i IT18, ma waena o IT01 e hōʻike ana i ka pololei machining kiʻekiʻe loa o ka ʻāpana, IT18 e hōʻike ana i ka pololei machining haʻahaʻa loa o ka ʻāpana. No IT7 ka mīkini mining maʻamau, a no IT8 ka mīkini mahiʻai maʻamau. Wahi a nā hana like ʻole o nā ʻāpana huahana, ʻokoʻa ka pololei o ka mīkini e pono ai e hoʻokō, a ʻokoʻa hoʻi ke ʻano hana a me ke kaʻina hana i koho ʻia.
