He aha nāwiliwili?

ʻO Twist drill kahi huaʻōlelo maʻamau no nā ʻano hoʻoheheʻe like ʻole, e like me nā wili metala, nā wili plastik, nā wili lāʻau, nā hoʻoheheʻe honua, nā masonry a me nā drills concrete.He ʻano maʻamau ko nā ʻōniu wili a pau: ʻO nā ʻohe helical e hāʻawi i ka inoa i nā drills.Hoʻohana ʻia nā wiliwili ʻokoʻa ma muli o ka paʻakikī o ka mea e hana ʻia.

Ma ke kihi helix

wili wili

ʻAno N

He kūpono no nā mea maʻamau e like me ka hao hao.
ʻO ke ʻano ʻoki ʻoki ʻano N ka mea maʻalahi ma muli o kona kihi wili o approx.30°.
ʻO ka huina kiko o kēia ʻano he 118°.

ʻAno H

Kūpono no nā mea paʻakikī a palupalu e like me ke keleawe.
ʻO ke ʻano helix ʻano H ma kahi o 15°, kahi e loaʻa ai kahi kihi wili nui me kahi ʻoki ʻoki liʻiliʻi akā paʻa loa.
He 118° ka huina kiko o na drill Type H.

ʻAno W

Hoʻohana ʻia no nā mea palupalu e like me ka alumini.
ʻO ka huina helix o approx.ʻO 40° ka hopena i kahi kihi wili liʻiliʻi no ka ʻoki ʻoki ʻoi a paʻa ʻole.
He 130° ka huina kiko.

Ma ka mea

Ke kila māmā holo kiʻekiʻe (HSS)

Hiki ke hoʻokaʻawale ʻia ka mea i ʻekolu mau ʻano: ke kila kiʻekiʻe, ke kila kiʻekiʻe i loko o ka cobalt a me ka carbide paʻa.

Mai ka makahiki 1910, ua hoʻohana ʻia ke kila kiʻekiʻe ma ke ʻano he mea ʻokiʻoki no hoʻokahi kenekulia.ʻO ia ka mea i hoʻohana nui ʻia a maʻalahi loa no ka ʻoki ʻana i nā mea hana.Hiki ke hoʻohana ʻia nā wili kila kiʻekiʻe ma nā ʻoihana lima a ʻoi aku ka paʻa e like me ka mīkini wili.ʻO kekahi kumu ʻē aʻe e lōʻihi ai ka lōʻihi o ke kila kiʻekiʻe no ka mea hiki ke hoʻohana hou ʻia nā mea hana ʻoki kila kiʻekiʻe.Ma muli o kona kumukūʻai haʻahaʻa, ʻaʻole hoʻohana wale ia i nā drillbits, akā hoʻohana nui ʻia i nā mea hoʻohuli.

Ke kila māmā holo kiʻekiʻe (HSS)
ʻO ke kila kiʻekiʻe ka wikiwiki o ka Cobalt

ʻO ke kila māmā holo kiʻekiʻe (HSSE)

ʻOi aku ka paʻakikī a me ka paʻakikī ʻulaʻula i loko o ka Cobalt ma mua o ke kila kiʻekiʻe.ʻO ka hoʻonui ʻana i ka paʻakikī e hoʻomaikaʻi i kona pale ʻana i ka ʻaʻahu, akā i ka manawa like e kaumaha ai i kahi ʻāpana o kona paʻakikī.E like me ke kila kiʻekiʻe: hiki ke hoʻohana ʻia e hoʻonui i ka nui o nā manawa ma o ka wili.

Carbide (CARBIDE)

ʻO Cementcarbide kahi mea hoʻohui metala.I waena o lākou, hoʻohana ʻia ka tungsten carbide e like me ka matrix, a hoʻohana ʻia kekahi mau mea ʻē aʻe e like me nā mea hoʻopaʻa i ka sinter e ke kaomi isostatic wela a me ke ʻano o nā kaʻina hana paʻakikī.Ke hoʻohālikelikeʻia me ke kila kiʻekiʻe ma keʻano o ka paʻakikī, ka paʻakikīʻulaʻula a me ke kū'ē kū'ē, ua hoʻomaikaʻi nuiʻia.Akā ʻoi aku ka maikaʻi o ke kumukūʻai o nā mea ʻoki carbide cemented ma mua o ke kila kiʻekiʻe.ʻOi aku ka maikaʻi o ka carbide Cemented ma mua o nā mea hana ma mua e pili ana i ke ola o ka hāmeʻa a me ka wikiwiki o ka hana.I ka wili pinepine ʻana i nā mea hana, pono nā mea hana wili ʻoihana.

Carbide (CARBIDE)

Ma ka uhi ʻana

ʻAʻole i uhi ʻia

ʻAʻole i uhi ʻia

Hiki ke hoʻokaʻawale ʻia nā uhi i ʻelima mau ʻano e like me ke ʻano o ka hoʻohana ʻana:

ʻO nā mea hana i uhi ʻole ʻia ʻo ia ka mea liʻiliʻi loa a hoʻohana mau ʻia e hana i kekahi mau mea palupalu e like me ke alumini alumini a me ke kila kalapona haʻahaʻa.

ʻAi ʻEleʻele

Hiki ke hāʻawi i ka lubricant maikaʻi aʻe ma mua o nā mea hana uncoated, ʻoi aku ka maikaʻi o ka oxidation a me ka pale ʻana i ka wela, a hiki ke hoʻonui i ke ola lawelawe ma mua o 50%.

ʻAi ʻEleʻele
ʻO ka uhi nitride Titanium

ʻO ka uhi ʻana o Titanium Nitride

ʻO Titanium nitride ka mea uhi maʻamau, a ʻaʻole kūpono ia no nā mea me ka paʻakikī kiʻekiʻe a me nā wela hoʻoili kiʻekiʻe.

ʻO ka uhi ʻana o Titanium Carbonitride

Hoʻokumu ʻia ʻo Titanium carbonitride mai ka titanium nitride, ʻoi aku ka kiʻekiʻe o ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa ʻaʻahu, maʻamau ka poni a i ʻole ka uliuli.Hoʻohana ʻia ma ka hale hana ʻo Haas e mīkini i nā mea hana i hana ʻia me ka hao.

Ka uhi ʻana o Titanium carbonitride
ʻO ka uhi ʻana o Titanium Aluminum Nitride

ʻO ka uhi ʻana o Titanium Aluminum Nitride

ʻOi aku ke kūpaʻa o ka Titanium alumini nitride i nā wela kiʻekiʻe ma mua o nā uhi a pau i luna, no laila hiki ke hoʻohana ʻia i nā wahi ʻoki kiʻekiʻe.No ka laʻana, ka hana ʻana i nā superalloys.He kūpono hoʻi ia no ka hana ʻana i ke kila a me ke kila kila, akā no ka loaʻa ʻana o nā mea alumini, e hana ʻia nā hopena kemika i ka wā e hoʻoili ai i ka alumini, no laila e pale i ka hana ʻana i nā mea alumini.

Manaʻo ʻia ka wikiwiki o ka wili ʻana ma ke metala

He aha nā haʻawina HSS?
ʻO nā drills HSS he mau kila kila i hōʻike ʻia e ko lākou hiki ke hoʻohana honua.ʻOi aku i ka hana liʻiliʻi a me ka liʻiliʻi, i nā kūlana mīkini paʻa ʻole a i ka wā e koi ʻia ai ka paʻakikī, hilinaʻi mau nā mea hoʻohana i nā mea hana wili kila kiʻekiʻe (HSS/HSCO).

Nā ʻokoʻa i nā hoʻomaʻamaʻa HSS
Hoʻokaʻawaleʻia ke kila kiʻekiʻe i nā kūlana maikaʻi likeʻole ma muli o ka paʻakikī a me ka paʻakikī.ʻO nā ʻāpana Alloy e like me tungsten, molybdenum a me cobalt ke kuleana no kēia mau waiwai.ʻO ka hoʻonui ʻana i nā ʻāpana alloy e hoʻonui i ke kūʻē ʻana i ka hoʻoheheʻe ʻana, ke kūpaʻa a me ka hana o ka mea hana, a me ke kumukūʻai kūʻai.ʻO ia ke kumu he mea nui e noʻonoʻo i ka nui o nā lua e hana ʻia i kahi mea i ke koho ʻana i ka mea ʻoki.No kahi helu liʻiliʻi o nā puka, ʻoi aku ka maikaʻi o ka ʻoki ʻoki ʻana i nā mea HSS.Pono e koho ʻia nā mea ʻoki kiʻekiʻe e like me HSCO, M42 a i ʻole HSS-E-PM no ka hana moʻo.
