ʻO nā hāʻina mīkini no nā kumu lohi

1. He aha ke kumu lohi?

ʻO ka lākiō me ka lakio o ka lōʻihi a me ke anawaena ʻoi aku ka nui ma mua o 25 (ʻo ia hoʻi L/D>25) ua kapa ʻia he lāʻau slender.E like me ka wili keʻokeʻo, ka pā maʻemaʻe a pēlā aku ma ka lathe.

2. ʻO ka paʻakikī o ka hana ʻana o ke kumu lohi:

Ma muli o ka rigidity maikaʻi ʻole o ka slender shaft a me ka mana o ka ʻoki ʻana i ka ikaika, ka ʻoki ʻana i ka wela a me ka haʻalulu i ka wā o ka huli ʻana, maʻalahi ka hana ʻana i ka deformation, a me nā hewa machining e like me ka pololei a me ka cylindricity, a paʻakikī ke hoʻokō i ke ʻano a me ke kūlana. pololei a me ka maikaʻi o ka ʻili ma ke kaha kiʻi.ʻO ia mau koi ʻenehana he mea paʻakikī loa ka ʻoki ʻana.ʻO ka nui o ka waiwai L/d, ʻoi aku ka paʻakikī o ke kaʻina hoʻohuli.

3. Nā pilikia koʻikoʻi i ka hana ʻana i nā lāʻau lohi:

ʻAʻole maikaʻi ka ʻoʻoleʻa o ka lāʻau lohi.Ma muli o ka mana o nā mea he nui e like me nā mīkini mīkini a me nā mea ʻoki ʻoki, hiki i ka mea hana ke kū i nā hemahema e like me ka pahu pūhaka curved, polygonal shape, a me ke ʻano hui ʻohe, ʻoi loa i ka hana wili.ʻO ka maʻamau, ʻilihune ka nui a he ʻeleʻele ka ʻili.He kiʻekiʻe ke kiʻekiʻe o ka paʻakikī, a no ka mea e pono ai ka hana wela e like me ke kinai ʻana a me ka hoʻomaʻamaʻa ʻana i ka wā o ka wili ʻana, ʻo ka ʻoki ʻana i ka wela i ka wā e wili ai ka mea e ʻoi aku ka deformation o ka mea hana, a pēlā aku. he kaʻina hana ultra-fine.Nā pilikia kī axis lōʻihi.

4. ʻO ka hoʻonā BXD:

ʻO ka ʻenehana koʻikoʻi o ka hoʻohuli ʻana i nā shaft slender ʻo ia ka pale ʻana i ka deformation kulou i ka wā o ka hana ʻana, pono e lawe ʻia nā ana mai nā fixtures, nā mea hana mīkini, nā kaʻina hana, nā ʻenehana hana, nā mea hana a me nā mea ʻokiʻoki.Ke alo nei i ka hana ʻana i nā ʻāpana liʻiliʻi, loaʻa i ka Speed ​​​​Screen nā hoʻonā kūʻokoʻa no ka hoʻokumu ʻana i nā hoʻolālā kaʻina hana, ke koho ʻana i nā mea hana, a me ka hoʻolālā ʻana o nā mea paʻa.ʻO ka maʻamau, hana ʻia ka mīkini ʻana o nā shaft slender e nā lathes CNC.No nā lāʻau liʻiliʻi me nā koi kiʻekiʻe e pili ana i ka concentricity, ʻoiai inā ʻaʻole ʻae ka hoʻolālā ʻana o nā ʻāpana i ka hana U-turn, e koho ʻo Speed ​​​​Plus i nā mea hana hana multi-axis (e like me nā lathes CNC ʻehā a i ʻole ka mīkini kikowaena ʻelima axis) e hoʻoponopono i nā ʻāpana i kahi manawa.
