1. Nā ʻano kūkulu o ka mea hana
ʻO ke ʻano o ka workpiece i hoʻopaʻa ʻia me ka paia lahilahinā kaupaona huilaHe ʻano peʻahi, ʻo QT600 ka mea hana, ʻo 187-255 HBW ka paʻakikī, ʻo loko he lua kūikawā, a ʻo ka ʻāpana lahilahi loa he 4 mm wale nō ka mānoanoa. Ua hōʻike ʻia nā koi pololei o ka poloka kaulike ma ke Kiʻi 1. ʻO ke anawaena o ka lua waena B benchmark he Φ69.914-69.944 mm, a ʻo 0.03 mm wale nō ka hoʻomanawanui. Aia ma lalo kahi lua hakahaka i hoʻopili ʻia. Hana ʻia ka ʻoki ʻana i ka wā e hana ai i ka mīkini i ka lua kuhikuhi C a me ka pōʻai waho. ʻO 4 mm wale nō ka mānoanoa o ka paia ma ʻaneʻi, he maʻalahi ke hana i ke kaumaha ʻoki a me ka deformation a hoʻopilikia i ka nui o ka hoʻomanawanui o ka lua kuhikuhi B, he wahi paʻakikī ia i ka hana ʻana i ka workpiece.
2. Nā Pōʻino Huna o ka Hana Lima Kuʻuna
Hoʻololi maʻalahi nā ʻāpana paia lahilahi i ka wā o ke kaʻina hana wili, ʻo ia hoʻi ma muli o ka hoʻololi ʻana i hana ʻia e ka ʻoki ʻana i ke kaumaha a me ka hoʻopaʻa ʻana. Hoʻoponopono ʻia ka hoʻolālā hana kuʻuna e ke kikowaena mīkini CNC a me ka lathe CNC, i māhele ʻia i ʻelua mau kaʻina hana. ʻO kekahi ka hana OP10. E hoʻohana i ka mea ʻoki wili diski Φ60 mm e wili a hoʻopau i ka mokulele o luna i ka nui o ke kaha kiʻi, e hoʻohana i ka mea ʻoki wili alloy Φ20 mm e wili i ka lua o loko Φ51.04-51.07 mm a i Φ50.7 mm (e waiho ana i 0.3-0.4 mm), e hoʻohana i ka mea ʻoki wili Alloy Φ20 mm no ka lua o loko Φ69.914～69.944 mm a i Φ69.6 mm (e waiho ana i 0.3～0.4 mm), ka lua o loko wili maikaʻi Φ51.04～51.07 mm a me Φ69.914～69.944 mm me ka mea ʻoki wili maikaʻi, e wili i 2 ×Φ18 mm me ʻelua mau lua liʻiliʻi. ʻO ka lua ka hana OP20. ʻO ka pōʻai waho "C" o ka wili ʻino a maikaʻi e kūlike me nā koi loea o ke kaha kiʻi.
ʻO ka paʻakikī o ka mīkini hananā kaupaona huila, ua hana ʻia ka lua kuhikuhi B, i ka nui i koi ʻia e ke kaha kiʻi ma ke kaʻina hana OP10. Wehe i ka ʻāpana hana a ana i ke anawaena o ka lua kuhikuhi B, Φ69.914~69.944 mm, a ʻo ka hewa ovality he 0.005~0.015 mm, a ua kūlike ka nui me nā koi o ke kaha kiʻi. Eia naʻe, ma hope o ka hana ʻana o ka OP20, wehe i ka ʻāpana hana a ana i ke anawaena o ka lua kuhikuhi o B, Φ69.914-69.944 mm, a ʻo ka hewa ovality he 0.03-0.04 mm. Hiki ke ʻike ʻia ua ʻoi aku ke anawaena ma mua o nā koi o ke kaha kiʻi.
3. Hoʻonā
Hoʻomaikaʻi i nā mea hana. Inā pololei ka hoʻolālā ʻana o ka mea hoʻopaʻa, he hopena pololei ia i ka hōʻoia ʻana i ka pololei o ka mīkini ʻana o ka ʻāpana hana, hoʻomaikaʻi i ka huahua hana a hoʻemi i ka ikaika o ka hana a nā limahana. Ma muli o nā ʻano o nā ʻāpana paia lahilahi, ʻo ka ikaika hoʻopaʻa nui a i ʻole ka ikaika like ʻole e hana i ka deformation elastic o ka ʻāpana hana, kahi e hoʻopilikia ai i ka pololei o ka nui a me ke ʻano o ka ʻāpana, a i ka hopena e alakaʻi ai i ka nui o ka ʻāpana i hana ʻia ma waho o ke ahonui. I mea e hoʻoponopono ai i kēia pilikia, pono e koho pono ʻia ke kumu hoʻohālike a me ka nui o ka cylinder clamping a me ka cylinder kākoʻo i ka wā e hoʻolālā ai i nā mea hana hydraulic.
