Nā kila māmā holo kiʻekiʻe (HSS)

(High speed steel (HSS)), ua hoʻohana mua ʻia ma ke ʻano he mea ʻokiʻoki (no nā mea ʻokiʻoki) a he kila kila kila kiʻekiʻe.Hoʻohana pū ʻia ʻo HSS no nā mea hana hana no ka mea maikaʻi loa ia no ka wili ʻana (e ʻae nō hoʻi i ka wili hou ʻana i nā mea hana blunt, no ka laʻana).

Ke hoʻohālikelike ʻia me nā kila hana anu, ʻokiʻoki i ka wikiwiki ʻekolu a ʻehā mau manawa kiʻekiʻe a no laila hiki ke hoʻokō ʻia nā mahana noi kiʻekiʻe.ʻO kēia ma muli o ka hoʻomaʻamaʻa wela kahi i hoʻopili ʻia ai ke kila ma luna o 1,200 °C a laila hoʻomaha.

Loaʻa ka HSS i kona paʻakikī mai kona ʻano kumu, ʻo ia ka nui o ka hao a me ke kalapona.Eia kekahi, ʻoi aku ka nui o nā mea hoʻohui i ʻoi aku ma mua o 5%, e hana ana i ka HSS i ke kila kila kiʻekiʻe.

Nā pōmaikaʻi o ka HSS ma ka laulā

· Ma luna o 600°C ka wela o ka noi

· Nā māmā ʻoki kiʻekiʻe

· Kaha kiʻekiʻe (kiʻekiʻe haʻi ikaika)

· Maikaʻi ka grindability i ka wā hana

· Maikaʻi rerindability o blunt mea paahana

· Ke kumu kūʻai haʻahaʻa

ʻOi aku ka kiʻekiʻe o ka cobalt content, ʻoi aku ka paʻakikī o ke kila mea hana.Hoʻonui ka ʻike cobalt i ke kūpaʻa paʻakikī wela a hiki iā ʻoe ke ʻoki maikaʻi i nā mea paʻakikī e ʻoki.Aia ka M35, 4.8 - 5 % cobalt a me M42, 7.8 - 8 % cobalt.Me ka hoʻonui ʻana i ka paʻakikī, e emi ana ka paʻakikī.

Nā noi

ʻO ke kila wikiwiki kiʻekiʻe, me kona mau kiʻekiʻe o ka paʻakikī a me nā uhi, kūpono no nāʻano likeʻole.

ʻO ke kila kiʻekiʻe ka wikiwiki āu e pono ai no kāu noi e pili ana i kāu kaʻina ʻoki, inā ʻoe e wili ana, threading a countersinking paha.

Ka hopena a me ka hōʻuluʻulu manaʻo

Hana ʻia nā drill me ke kila kiʻekiʻe kiʻekiʻe i hoʻohui ʻia (HSS).Me kēia kila mea hana, hiki ke kiʻi ʻia nā mahana noi a hiki i 600 °C, hiki ke hana i ka wā e ʻoki ai, e laʻa me ke kila a me nā metala.

Ke piʻi aʻe ka paʻakikī o ka mea, hiki iā ʻoe ke hoʻohana i ke kila kiʻekiʻe me ka ʻike cobalt kiʻekiʻe (5% a i ʻole).ʻO ke kiʻekiʻe o ka ʻike cobalt e pili ana i kāu noi.No ka laʻana, inā makemake ʻoe e wili i ke kila kila, hoʻohana maʻamau ʻoe i kahi drill wili M35 uncoated.I kekahi mau mea, ua lawa ke kila kila HSS me ka uhi TiAlN.

I kēia manawa hiki iā ʻoe ke koho i ke kila kūpono no kāu noi.
