wili palaoa (Rolling die, alloy material)
ʻO nā ʻāpana hana nui a me nā mea hana no ka hoʻomau ʻana i ka plastic deformation o ka metala ma ka wili wili. Loaʻa iā ia he cylindrical maʻemaʻe a i ʻole ka ʻili. ma o ke kumu hoʻohui, a hoʻoneʻe ʻia ka manawa hoʻololi o ke kaʻa i ka ʻōwili.
Hiki ke hoʻonohonohoʻia nā'ōwili ma keʻano o nā'ōwiliʻelua,ʻekolu,ʻehā aʻoi aʻe paha i loko o ka pahu wili.
Aia nā ʻano hoʻohālikelike like ʻole no nā wili, ʻo ia hoʻi: (1) E like me ke ʻano o ka huahana, aia nā ʻōwili ʻāpana, ʻōwili ʻāpana, ʻōwili uea, etc. (2) E like me ke kūlana o ka ʻōwili i loko.ka wiliwilimoʻo, aia nā blank roll, rough roll, hoʻopau roll, etc.;(3) E like me ka hana o ka ʻōwili, aia nā ʻōwili unahi, perforating roller, leveling roller, etc.; (4) E like me ka ʻōwili mea mahele i loko o ke kila wili, hoolei hao wili, carbide roll, ceramic roll, etc.;(5) E like me ka manufacturing hana, hiki ke maheleia i ka hoolei ana i ka roll, forging roll, surfacing roll, sleeve roll, etc.;(6) Wahi a ke kūlana o ke kila i'ōwiliʻia, aia nā'ōwili wela, ka'ōwili anu. Hiki ke hoʻohuiʻia nāʻano likeʻole no ka hāʻawiʻana i kahi manaʻo kiko'ī i ka'ōwili, e like me ka centrifugal kiʻekiʻe chromium hoʻolei i ka hao hana'ōwili no ka wela'ōwili hao kila.
