He aha ka HSS Twist Drill Bit?
ʻO ka HSS twist drill kahi ʻano mea hana wili i hana ʻia me ke kila kiʻekiʻe i hoʻohana ʻia no ka hana metala. ʻO ka HSS he kila kila kūikawā me ke kūpaʻa abrasion maikaʻi loa, ke kūpaʻa wela, a me ka ʻoki ʻana i nā waiwai, e kūpono ana ia no nā hana metala e like me ka wili. ʻO kahi drill wili (ʻike ʻia ʻo auger a i ʻole spiral flute drill) he drill me nā ohe helical e ʻae ai i ka ʻoki ʻoki ʻana i nā ʻāpana e puka koke i ka lua drill, e hōʻemi ana i ka friction a me ka wela i ka wā wili a me ka hoʻomaikaʻi ʻana i ka pono wili. ʻO ka hoʻolālā ʻana o ka HSS twist drills e kūpono iā lākou no kahi ākea o nā mea metala like ʻole, e like me ke kila, aluminika, keleawe a me nā ʻāpana, etc.
Nā ʻano o nā wili wili kila kiʻekiʻe
1. Kū'ē Kū'ē Kiʻekiʻe: Hōʻike nā mea kila kiʻekiʻe i ke kū'ēʻana i ka abrasion maikaʻi, eʻae ana i kaʻokiʻokiʻana i kaʻoi aku no nā manawa lōʻihi.
2. Paʻa wela kiʻekiʻe: Hiki i ke kila kiʻekiʻe ke hana ma nā wahi wela wela me ka nui ʻole o ka paʻakikī a i ʻole deformation.
3. Hana maikaʻi i ka ʻoki ʻana: ʻO ka hoʻolālā spiral groove o nā drill drills kōkua i ka ʻoki metala maikaʻi ʻoiai e hōʻemi ana i ka hōʻiliʻili chip.
4. ʻOi aku ka maikaʻi o ka mīkini ʻenehana: Hāʻawi maʻamau nā puʻupuʻu wili kila kiʻekiʻe i ka maikaʻi me nā ana kikoʻī a me nā ʻili laulima.
Nā ʻano HSS a mākou i hoʻohana ai no kā mākou wili wili
ʻO nā māka nui o ka HSS a mākou e hoʻohana nei: M42, M35, M2, 4341, 4241.
Aia kekahi mau ʻokoʻa ma waena o lākou, pili nui i kā lākou ʻano kemika, paʻakikī, kūpaʻa wela a me nā wahi o ka noi. Aia ma lalo nā ʻokoʻa nui ma waena o kēia mau māka HSS:
1. M42 HSS:
Loaʻa i ka M42 ka 7% -8% cobalt (Co), 8% molybdenum (Mo) a me nā mea hoʻohui ʻē aʻe. Hāʻawi kēia iā ia i ʻoi aku ka maikaʻi o ke kūpaʻa abrasion a me ke kūpaʻa wela. ʻOi aku ka ʻoi aku o ka paʻakikī o ka M42, a ʻo kona paʻa pōhaku ʻo 67.5-70(HRC) hiki ke loaʻa i nā ʻenehana lapaʻau wela.
2. M35 HSS:
Loaʻa iā M35 ka 4.5% -5% cobalt a loaʻa pū kekahi i ka pale abrasion nui a me ke kūpaʻa wela. ʻOi aku ka paʻakikī o M35 ma mua o ka HSS maʻamau a mālama mau i ka paʻakikī ma waena o 64.5 a me 67.59(HRC). He kūpono ʻo M35 no ka ʻoki ʻana i nā mea pili e like me ke kila kila.
3. M2 HSS:
Loaʻa i ka M2 nā kiʻekiʻe kiʻekiʻe o ka tungsten (W) a me ka molybdenum (Mo) a he mau waiwai ʻoki maikaʻi. ʻO ka paʻakikī o M2 ka mea maʻamau i ka laulā o 63.5-67 (HRC), a he kūpono ia no ka hana ʻana i nā metala e pono ai nā koi kiʻekiʻe.
4. 4341 HSS:
ʻO 4341 HSS he kila kiʻekiʻe me ka haʻahaʻa haʻahaʻa haʻahaʻa e pili ana i ka m2. Mālama ʻia ka paʻakikī ma luna o 63 HRC a kūpono no nā hana hana metala maʻamau.
5. 4241 HSS:
ʻO 4241 HSS kekahi HSS huila haʻahaʻa i loaʻa nā mea hoʻohui liʻiliʻi. Mālama ʻia ka paʻakikī ma kahi o 59-63 HRC a hoʻohana mau ʻia no ka hana metala maʻamau a me ka wili.
ʻO ke koho ʻana i ka māka kūpono o ka HSS e pili ana i kāu pono noi kikoʻī a me ke ʻano o nā mea e hana ʻia. ʻO ka paʻakikī, ka pale abrasion a me ke kūpaʻa wela ka mea nui i ke koho.
