Nā ʻāpana mīkini mahiʻai, nā palau a me nā ʻōpeʻapeʻa
- ʻO ka palau ka ʻāpana ʻokiʻoki koʻikoʻi o ka palau moldboard, me kahi hoʻolālā ʻili piʻo e like me ke ʻano wedge. Hoʻopili ʻia ia i ke kino palau ma o nā ʻāpana e like me ka paia palau a me ke kumu palau e hoʻokō ai i nā hana o ka wāwahi ʻana a me ka huli ʻana i ka lepo.
- Nā mea nui: kila 65Mn a i ʻole kila 60Si2Mn, me ka paʻakikī mai HRC3 a 49. Ua hana ʻia kekahi mau hiʻohiʻona i ka quenching a me ka tempering a i ʻole ka mālama ʻana i ka uhi ʻana e hoʻoikaika i ke kūpaʻa ʻana i ka ʻaʻahu.
- Ma o nā ʻenehana hana ʻana a me ka mālama wela, ua hōʻoia ʻia ka hoʻonohonoho ʻana o ka ʻāpana e paʻa a paʻa
1, Mea Hana: Hana ʻia me ke kila puna 65Mn a i ʻole ke kila kalapona kiʻekiʻe, ke hana nei kēia pahi i kahi kaʻina hana wela kikoʻī (quenching a me ka tempering) e hoʻokō ai i ka paʻakikī koʻikoʻi a me ke kū'ē ʻana i ke kapa ʻokiʻoki, ʻoiai e mālama ana i ka paʻakikī maikaʻi loa i ka ʻaoʻao ʻoki ʻole e pale pono ai i ka chipping.
2, ʻenehana: Loaʻa i kekahi mau hiʻohiʻona kahi hana hoʻopaʻakikī kūikawā ma ka ʻaoʻao ʻokiʻoki, e hoʻonui ana i ke kūpaʻa ʻana o ka ʻaʻahu ma mua o 50% i hoʻohālikelike ʻia me nā pahi maʻamau, e hōʻemi nui ana i ka alapine hoʻololi a me nā kumukūʻai hana lōʻihi.
3, Hāʻawi mākou i nā ʻano hoʻohālike like ʻole (e like me nā ʻō pala chisel, nā ʻō pala wāwae duck, nā ʻō pala ākea, a me nā mea ʻē aʻe), hiki ke hoʻololi pono i nā ʻano palau like ʻole e like me nā palau moldboard, nā palau hoʻohuli, a me nā palau amplitude-modulated o nā lama kūloko a me nā haole.
ʻO ka pahi coulter, kahi ʻāpana mahiʻai koʻikoʻi i kau ʻia ma ke alo o ka palau, ua kapa ʻia ʻo "ka pahi ʻoi o ka palau." ʻO kāna hana nui, ʻo ia ke komo ʻana, ʻokiʻoki, a wāwahi i ka lepo i ka wā mahiʻai, e hana ana i kahi ʻano ākea, pālahalaha, a momona no ka lūlū ʻana a me ka ulu ʻana o nā mea kanu ma hope. Hana ʻia me ka hoʻohana ʻana i ka ʻenehana holomua a me nā mea hana kiʻekiʻe, hāʻawi kā mākou mau pahi coulter i ke kūpaʻa ʻana i ka ʻaʻahu, nā hiki ke wāwahi lepo ikaika, a me ke ola lawelawe lōʻihi, e lilo ia i mea kōkua nui i ka mahiʻai hou a kūpono.
