Nā hiʻohiʻona o kahi mea ʻoki wili

Nā mea ʻoki wilihele mai ma nā ʻano like ʻole a me nā ʻano nui.Aia kekahi koho o nā uhi, a me ke kihi rake a me ka helu o nā ʻokiʻoki.

• ʻano:Nui nā ʻano maʻamau omea ʻoki wilihoʻohana ʻia i ka ʻoihana i kēia lā, i wehewehe ʻia ma lalo nei.
• Nā ʻohe / niho:ʻO nā ʻōheʻe o ka bit wili, ʻo ia nā ʻauwai helical hohonu e holo ana i luna o ka mea ʻoki, ʻoiai ʻo ka pahi ʻoi ma ka lihi o ka ʻohe i kapa ʻia ʻo ka niho.ʻOki ka niho i ka mea, a huki ʻia nā ʻāpana o kēia mea i ka ʻohe ma ka ʻōwili ʻana o ka mea ʻoki.Aneane hoʻokahi niho no ka ʻohe, akā ʻelua niho o ka ʻokiʻoki i ka ʻohe.ʻO ka pinepine, nā ʻōlelooheanihohoʻohana like ʻia.Hiki i nā mea ʻoki wili mai hoʻokahi a i nā niho he nui, ʻelua, ʻekolu a me ʻehā ka mea maʻamau.ʻO ka maʻamau, ʻoi aku ka nui o nā niho i loaʻa i ka mea ʻoki, ʻoi aku ka wikiwiki o ka wehe ʻana i nā mea.No laila, aʻoki niho 4hiki ke hoʻoneʻe i nā mea i ʻelua manawa o ka aʻoki niho ʻelua.
• Helix kihi:ʻO nā ʻohe o ka mea ʻoki wili ʻaneʻane helical mau.Inā pololei nā ʻohe, e hoʻopilikia ka niho holoʻokoʻa i ka mea i ka manawa hoʻokahi, e haʻalulu a hōʻemi i ka pololei a me ka maikaʻi o ka ʻili.ʻO ka hoʻonohonoho ʻana i nā ʻohe ma kahi kihi e hiki ai i ka niho ke komo mālie i ka mea, e hōʻemi ana i ka haʻalulu.ʻO ka mea maʻamau, ʻoi aku ka kiʻekiʻe o nā ʻokiʻoki hoʻopau (helix paʻa) e hāʻawi i ka hopena maikaʻi aʻe.
• ʻoki kikowaena:Hiki i kekahi mau mea ʻoki wili ke wili pololei i lalo (plunge) ma o ka mea, ʻaʻole hiki i kekahi.ʻO kēia no ka mea ʻaʻole hele nā ​​niho o kekahi mau mea ʻoki i ke ala āpau i ke kikowaena o ka maka hope.Eia naʻe, hiki i kēia mau ʻokiʻoki ke ʻoki i lalo ma kahi kihi o 45 degere a i ʻole.
• Hoʻopau a hoʻopau paha:Loaʻa nā ʻano ʻoki like ʻole no ka ʻoki ʻana i ka nui o nā mea, waiho ʻana i ka hopena maikaʻi ʻole (roughing), a i ʻole ka wehe ʻana i kahi mea liʻiliʻi, akā e waiho ana i kahi hopena maikaʻi (hoʻopau).He mea ʻokiʻokihe mau niho serrated no ka wawahi ʻana i nā ʻāpana mea i ʻāpana liʻiliʻi.Haʻalele kēia mau niho i kahi ʻili ʻeleʻele ma hope.Hiki i ka mea ʻoki hoʻopau ke loaʻa i nā niho nui (ʻehā a ʻoi aku paha) no ka wehe pono ʻana i nā mea.Eia nō naʻe, ʻaʻole liʻiliʻi kahi lumi no ka wehe ʻana i ka swarf ka nui o nā ʻohe, no laila ʻaʻole kūpono lākou no ka wehe ʻana i nā mea nui.
• Nā uhi:Hiki ke hoʻoikaika nui i ka ʻoki ʻoki ʻana i nā mea hana pono ma ka hoʻonui ʻana i ka wikiwiki o ka ʻoki ʻana a me ke ola mea hana, a me ka hoʻomaikaʻi ʻana i ka pau ʻana o ka ʻili.ʻO ke daimana polycrystalline (PCD) kahi uhi paʻakikī i hoʻohana ʻia ma lunanā mea ʻokiʻo ia ka mea e pale aku i ka ʻaʻahu abrasive kiʻekiʻe.Hiki i kahi mea hana i uhi ʻia PCD a hiki i ka 100 mau manawa lōʻihi ma mua o kahi mea hana i uhi ʻole ʻia.Eia naʻe, ʻaʻole hiki ke hoʻohana ʻia ka uhi ʻana ma nā mahana ma luna o 600 degere C, a i ʻole ma nā metala ferrous.Hāʻawi ʻia nā mea hana no ka mīkini alumini i kekahi manawa i kahi uhi o TiAlN.ʻO ka alumini he metala paʻa loa, a hiki ke hoʻopaʻa iā ia iho i nā niho o nā mea paahana, e hōʻike ʻia ai lākou he pōpō.Eia nō naʻe, ʻaʻole ia e pili i ka TiAlN, e ʻae i ka mea hana e hoʻohana ʻia no ka lōʻihi o ka alumini.
• Shank:ʻO ka shank ka ʻāpana cylindrical (non-fluted) o ka mea hana i hoʻohana ʻia e paʻa a loaʻa i loko o ka mea paʻa.He poepoe loa paha ka shank, a paa i ka paio, a i ole ia he Weldon Flat, kahi i hoonohoia ai ka wili, i ikeia no hoi he wili wili, e hoopili ai no ka hoonui ana i ka torque me ka pahee ole o ka mea hana.He ʻokoʻa paha ke anawaena mai ke anawaena o ka ʻāpana ʻoki o ka mea paahana, i hiki ke paʻa ʻia e kahi mea paʻa paʻa maʻamau.§ Hiki ke loaʻa ka lōʻihi o ka shank i nā ʻano nui like ʻole, me nā ʻāpana pōkole (ma kahi o 1.5x). ke anawaena) i kapa ʻia ʻo “stub”, lōʻihi (5x anawaena), ʻoi aku ka lōʻihi (8x anawaena) a ʻoi aku ka lōʻihi (12x anawaena).
