ʻO ke alakaʻi hope loa i ka ʻoki ʻana i nā mea hana: No ke aha e hoʻomalu ai ʻo Carbide a me Advanced Composite i ka papahele hale kūʻai

Inā hoʻokahi mea e ala ai ka luna hale kūʻai mīkini i ka pō, ʻo ia ka makaʻu i ka hana like ʻole. ʻIke ʻoe i ka manaʻo. Loaʻa iā ʻoe kahi kauoha nui o nā ʻāpana aerospace, ke holo nei ka mīkini, a paʻi koke. Haʻi ka mea hana, ʻoki ʻia ka ʻāpana, a paʻa kou palena. Ma Dezhou Drillstar Cutting Tool Co., Ltd, ʻike mākou i kēia hiʻohiʻona e pāʻani mau ana. ʻO ke kumu kumu? ʻO ka manawa pinepine, ʻaʻole ia ka mīkini; ʻo ia ka koho o ka mea paahana oki.

ʻO kēia ʻatikala kāu alakaʻi piha no ka hoʻomaopopo ʻana i ka mea paahana oki ʻāina. E luʻu hohonu mākou i ke kumu carbide ua lilo i ka ʻoihana maʻamau, e ʻimi i hea mea hana ʻoki keramika ʻālohilohi, a nānā i nā mea superhard e like me cubic boron nitride. Inā ʻoe e ʻoki ana hao hao, aluminika, a i ʻole kila paʻakikī, ʻo ka hoʻomaopopo ʻana i nā waiwai o kēia mau mea ka mea huna e wehe maikaʻi ai ola mea paahana a me ka pau ʻana o ka ʻili.

No ke aha he mea koʻikoʻi ke koho ʻana i ka mea hana ʻoki no kāu hana mīkini?

ʻO ka ke koho ʻana i ka mea hana ʻoki ʻo ia ka hoʻoholo nui loa i ka hana hana. ʻO ka mea ʻoki ʻoki ʻo ia ke kiko o ka pilina ma waena o kāu pipiʻi mea hana mīkini a me ka maka mea hana. Inā hāʻule kēlā wahi hoʻopili, pau nā mea ʻē aʻe.

ʻO ka mea mua, e noʻonoʻo i ka wela. I ka wā nā hana mīkini, nā mahana ma ka ʻoki ʻoki hiki ke piʻi aʻe ma luna o 1000 ° C. Ina ka mea paahana oki nele ʻoʻoleʻa wela, e palupalu a deform. Ke alakaʻi nei kēia i ka hoʻomanawanui maikaʻi ʻole a me kahi ʻāpana i hōʻole ʻia. Nā mea i hoʻohana ʻia i nā mea hana ʻoki pono e mālama i ko lākou kūpaʻa ʻoiai ke kau ka wela.

ʻO ka lua, pono mākou e kamaʻilio e pili ana ʻaʻahu kūʻē. Pono e hoʻololi pinepine ʻia kahi mea hana e hoʻopau koke. Hoʻopau kēia downtime i ka pono. Ma ke koho ʻana i ka mea ʻoki pono me ke koena kupono o ʻoʻoleʻa a me ke kūpale ʻaʻahu, hōʻoia ʻoe e neʻe mau ana kāu laina hana. E pili ana i ka wānana. Ke kūʻai aku ka mea hoʻolaha e like me ʻoe i kahi mea hana i kahi hale kūʻai mīkini, pono lākou e ʻike e mau ana ia no 500 mau ʻāpana, ʻaʻole e hāʻule i 50.

He aha nā ʻano nui o nā mea hana ʻoki i loaʻa i kēia lā?

Ka moolelo o ʻoki metala he moʻolelo maoli o ka ʻepekema waiwai. I ke kenekulia i hala aku nei, ua neʻe mākou mai nā kila kalapona maʻalahi a hiki i nā composites kiʻekiʻe e hiki ke ʻoki ʻia i loko o nā alloys paʻakikī e like me ka pata.

Eia ka wehewehe wikiwiki o ka ʻano mea paahana ʻoki ʻike pinepine mākou:

• Ke kila māmā holo kiʻekiʻe (HSS): ʻO ka mea hilinaʻi kahiko. Paʻakikī, akā nele ka wikiwiki.
• Carbide sima: Ka lio hana. maikaʻi loa ʻaʻahu kūʻē a me nā hiki wikiwiki.
• ʻO nā keramika: ʻO nā daimonio wikiwiki. Nui no ka wela nui, akā palupalu.
• Cermets: ʻO kahi hui o ka seramika a me ka metala. Nui no ka hoʻopau ʻana.
• Mea Paa Paa (CBN & PCD): ʻO nā loea no ka paʻakikī loa a i ʻole nā mea abrasive.

Ka hoomaopopo ana i keia mau mea ʻano ʻokiʻoki kōkua nā mea hana iā ʻoe e hoʻohālikelike i ka hāmeʻa me ka noi. ʻAʻole ʻoe e hoʻohana i ka hāmare aniani e hoʻokuʻi ai i ke kui, a ʻaʻole pono ʻoe e hoʻohana i ka HSS e hoʻohuli i ke kila kila paʻakikī.

No ke aha i hoʻopaʻa ʻia ai ka carbide cemented i ke kūlana ʻoihana no ka mīkini ʻenehana hou?

Inā hele ʻoe i loko o kekahi hale kūʻai CNC hou, ʻo ka hapa nui o nā mea hana āu e ʻike ai - nā wili hope, drills, inserts - ua hana ʻia me carbide sima. Akā, he aha ia?

carbide sima he mea hui. Aia i loko o ka paʻakikī tungsten carbide nā ʻāpana i hoʻopaʻa ʻia e ka mea hoʻopaʻa metala, maʻamau ka cobalt. E noʻonoʻo ʻoe e like me ke kaʻa: ʻo ka tungsten ka aggregate (pōhaku), a ʻo ka cobalt ka sima. Hāʻawi kēia hui mea hana kalapona he pono kū hoʻokahi. He paʻakikī lākou, hāʻawi kiʻekiʻe ʻaʻahu kūʻē, akā, hāʻawi ka mea hoʻopili cobalt i ka paʻakikī e pale aku i nā ʻokiʻoki me ka ʻole o ka haki ʻana.

Ma Drillstar, hoʻohana mākou i ka micro-grain kiʻekiʻe carbide nā lāʻau e hana i kā mākou Nā Koʻokoʻo Carbide Paʻa. ʻO ka ʻoi aku ka maikaʻi o ka palaoa, ʻoi aku ka ʻoi o ka ʻoi a mākou e wili ai, a ʻoi aku ka ikaika o ka mea hana. Nā mea hana ʻoki karbida hiki ke holo ma ka wikiwiki 2 a 3 manawa ʻoi aku ka wikiwiki ma mua o HSS, e unuhi pololei i ke kālā i mālama ʻia i ka manawa mīkini.

Pehea e hoʻohālikelike ai nā mea paahana High-Speed Steel (HSS) me nā mea hana ʻoki carbide?

Manaʻo paha ʻoe, inā carbide nui loa, no ke aha kiʻekiʻe-wikiwiki kila mau nō? Kiʻekiʻe-wikiwiki kila (HSS) he kipi i ka wā i hoʻokomo ʻia ai, e ʻae ana i ka nui kiʻekiʻe oki wikiwiki ma mua o ka ʻelemakule nā kila mea hana kalapona.

ʻO ka pono nui o ka HSS ʻo kona paʻakikī. Hiki iā ia ke komo i nā haʻalulu a me nā haʻalulu e paʻi a carbide mea paahana. He mea kūpono kēia i ka HSS no:

• ʻO nā mīkini kahiko a emi ʻole ka paʻa.
• ʻoki ʻoki ʻia.
• ʻO nā mea hana paʻakikī paʻakikī e wili mai ka carbide paʻa.

Eia naʻe, he nāwaliwali nui ko HSS: ʻoʻoleʻa wela. Ke ʻoki māmā piʻi, hana wikiwiki ka wela. Ma kahi o 600°C, HSS lilo kona paakiki. ʻokoʻa, mea hana carbide sima e mālama i ko lākou paʻakikī ma nā wela kiʻekiʻe. No nā wahi hana kiʻekiʻe kahi i aliʻi ai ka manawa pōʻai, ʻoki kalapona ʻaneʻane i nā manawa a pau ke koho maikaʻi loa.

I ka manawa hea ʻoe e hoʻohana ai i nā mea hana ʻoki keramika i kāu mīkini?

ʻO nā mea hana ʻoki seramika he mahele hoihoi. Ua haku ʻia lākou ma mua o alumini oxide a i ʻole nitride silika. Paʻa loa kēia mau mea a paʻa kemika. ʻAʻole lākou e pane me ka mea hana mea hana, ka mea e pale ai i ke kapa komo lua.

ʻOki keramika ʻālohilohi i nā hiʻohiʻona kikoʻī:

1. Ka Huli Kiʻekiʻe: Hiki iā ʻoe ke holo i nā seramika i ka wikiwiki o ka ʻili.
2. Huli paʻakikī: ʻO ke kila paʻakikī (hiki i 60-65 HRC).
3. Nā huila nui: Hoʻohana ʻia nā mea hoʻoheheʻe nickel i nā ʻenekini jet.

Eia naʻe, mea seramika loaʻa wela haʻahaʻa kū'ē i ka haʻalulu (ma kekahi mau māka) a he palupalu loa. Inā loaʻa iā ʻoe kahi mīkini me nā bearings ʻoluʻolu a inā ʻoe e hana nei i nā ʻoki kaumaha nui, a mea hana ʻoki keramika nahaha paha. Pono lākou i kahi hoʻonohonoho paʻa. Akā i ka hoʻohana pono ʻana, mea hana ʻoki keramika hiki ke hoʻoneʻe i ka metala ma ka uku carbide ʻaʻole hiki ke hoʻopā wale.

He aha ka Cubic Boron Nitride (CBN) a no ke aha ʻo ia ka lua o ka mea paʻakikī?

Ke kamaʻilio mākou e pili ana i nā mea paʻakikī loa ma ka honua, ʻo ka daimana ka helu ʻekahi. Akā aia ma hope pono cubic boron nitride (CBN). ʻO CBN ka lua mea paakiki ike kanaka.

Hoʻohana nui ʻia ʻo CBN no ka hana ʻana i nā metala ferrous paʻakikī. ʻAʻole e like me ke daimana, ʻaʻole pane ʻo CBN me ke kalapona i nā wela kiʻekiʻe, e palekana ai no ka ʻoki kila. Hoʻohana ʻia nā mea hana me nā ʻōlelo aʻoaʻo CBN no ka mīkini ʻana i nā kila paʻakikī, nā hao hoʻolei, a me nā hao i hoʻopaʻa ʻia.

ʻO ka hoʻohana ʻana iā CBN hiki i nā mea hana ke hoʻololi i nā hana wili me ka mīkini. He hana kēia i kapa ʻia ʻo "huli paʻakikī." Ma kahi o ka hoʻonohonoho ʻana i kahi huila wili, hoʻohana ʻoe i kahi hoʻokomo CBN e hoʻohuli i kahi lāʻau paʻakikī i ka nui. ʻOi aku ka wikiwiki a ʻoi aku ka maikaʻi o ke kaiapuni no ka mea e hoʻohana ana i ka mea hoʻomaha liʻiliʻi.

ʻO nā mea hana ʻoki daimana (PCD) ka hopena hope loa no nā mea non-ferrous?

ʻO nā mea hana Polycrystalline Diamond (PCD) nā mea hana ʻoki paʻakikī loa i loaʻa. ʻOki daimana hāʻawi like ʻole ʻaʻahu kūʻē. Eia naʻe, aia kahi hopu. ʻAʻole hiki iā ʻoe ke hoʻohana i ke daimana e ʻoki i ke kila.

No ke aha? No ka mea, he kalapona ke kila, a he kalapona maemae ke daimana. I nā wela kiʻekiʻe o ka mīkini, makemake nā ʻātoma kalapona i ka daimana e neʻe i loko o ke kila. Hoʻomaka kēia i ka ʻaʻahu kemika wikiwiki.

No laila, Nā mea hana PCD ʻo ia nā mea ʻoki maikaʻi loa koho no mea hao ole. Aia kēia me:

• Aluminum nā alumini (ʻoi aku ka nui-silikona alumini i hoʻohana ʻia i nā ʻenekini kaʻa).
• Ke keleawe a me ke keleawe.
• ʻO nā hui pūlima kalapona.
• Nā mea abrasive e like me ka laau a me ka seramika.

Inā ʻoe e hana ana i nā hale alumini no ka uila, hiki i kahi mea hana PCD ke lōʻihi i 50 a 100 mau manawa lōʻihi ma mua o kahi. mea hana ʻoki carbide sima.

Pehea e hoʻomaikaʻi ai nā uhi e like me Titanium Nitride i ka ʻoki ʻoki?

ʻO ka mea kumu he hapalua wale nō o ka moʻolelo. No ka loaʻa ʻana o kahi mea hana, hoʻohana pinepine mākou i kahi uhi lahilahi. ʻO ka mea kaulana loa ʻo ia ka uhi kala gula āu e ʻike ai ma nā bit drill: Titanium Nitride (TiN).

Hoʻohana nā coating i nā kumu he nui:

1. ʻoʻoleʻa: ʻOi aku ka paʻakikī ma mua o ka substrate, e pale ana i ka ʻoki ʻoki.
2. Lubricity: Hoʻemi lākou i ka hakakā ma waena o ka mea hana a me ka chip, e hoʻemi ana i ka wela.
3. Pale wela: He haʻahaʻa ko lākou ka hoʻoheheʻe wela, mālama i ka wela i loko o ka chip a ma waho o ka mea hana.

Ma waho aʻe o ka TiN, hoʻohana mākou i nā mea hoʻonaninani kiʻekiʻe e like me Titanium Carbonitride (TiCN) a me Aluminum Titanium Nitride (AlTiN). Maikaʻi loa ʻo AlTiN no mea ʻoki karbida hoʻohana ʻia i ka mīkini maloʻo no ka mea i ka wā e wela ai, hana ia i kahi papa pale o alumini oxide.

He aha nā mea e alakaʻi ai i kāu koho ʻana i ka mea ʻoki?

ʻO ka koho o ka mea paahana oki ʻaʻole pono he kuhi. Pono ia he hoʻoholo i helu ʻia ma muli o nā ʻokoʻa kikoʻī. Ke kūkākūkā mākou me nā mea kūʻai aku e pili ana i kā mākou ʻO nā wili karbida, nīnau mākou:

1. Mea Hana Mea Hana: ʻO ka alumini palupalu a i ʻole ka hao abrasive? Nā mea like Pono ka titanium i nā mea hana me nā waiwai kemika kūikawā e pale ai i ka hopu ʻana.
2. ʻoʻoleʻa: Inā ʻoi aku ka HRC ma luna o 50, pono ʻoe i ka carbide hana kiʻekiʻe a i ʻole CBN.
3. Kūlana Mīkini: Ua ʻoʻoleʻa paha kāu spindle? Inā ʻae, hiki iā ʻoe ke hoʻohana i nā māka ʻoi aku ka paʻakikī. Inā ʻaʻole, pono ʻoe i ka paʻakikī.
4. Ka nui hana: No kahi prototype, hiki ke maʻalahi a maikaʻi paha ka HSS. No 10,000 mau ʻāpana, ke kumu kūʻai-no ka ʻāpana o kahi uhi carbide haʻahaʻa loa ka mea hana.

ʻO ka mea hana pono ʻo ia ka mea e hāʻawi iā ʻoe i ke kumu kūʻai haʻahaʻa loa no ka lua a i ʻole kēlā me kēia ʻili mīkini, ʻaʻole pono ka mea me ke kumu kūʻai haʻahaʻa loa ma ka pahu.

Pehea mākou e wehewehe a ana i ke ola o nā mea hana ma nā mea like ʻole?

Mea ola ola ʻo ia ka manawa e ʻoki pono ai ka mea hana ma mua o ka hāʻule ʻana a i ʻole ka hana ʻana i nā ʻāpana kūpono ʻole. Loaʻa nā hemahema ma muli o mea paahana, ʻokiʻoki, a i ʻole ka hoʻololi ʻana i ka plastic.

In ʻoki carbide sima, ke ʻimi nei mākou i nā hiʻohiʻona ʻaʻahu hiki ke wānana. Makemake mākou e ulu mālie a me ka like ka ʻaʻahu ʻaoʻao. Ina ka ʻoki ʻoki chips (micro-cracks), hiki i ka mea hana ke hāʻule pōʻino.

ʻokoʻa ʻano ʻokiʻoki hana i ka lole like ʻole.

• Ka lole lua: He hoʻohaʻahaʻa concave ma ka maka mea hana, ma muli o ka hopena kemika a me ka wela. Mea maʻamau i ka ʻoki kila.
• Nā lole ʻaʻahu: Abrasion ma ka ʻaoʻao o ka mea paahana. ʻO kēia ka hana hope o ke ola maʻamau no ka hapa nui mea hana kalapona.

Hoʻohana i nā mea me ka kiʻekiʻe ʻoʻoleʻa wela a me ka paʻa kemika (like titanium carbide nā uhi a i ʻole nitride silika keramics) hoʻopaneʻe i kēia mau hana ʻaʻahu.

Pehea e pili ai ka conductivity thermal i ke kaʻina ʻoki?

ʻO ka wela ka ʻenemi. Hoʻomaopopo ʻia ka hiki o kahi mea ke mālama i ka wela e kāna ka hoʻoheheʻe wela.

I kekahi mau hihia, makemake ʻoe i ka conductivity kiʻekiʻe. No ka laʻana, he kiʻekiʻe loa ka hoʻoili wela o ka PCD (diamond) e kōkua i ka huki ʻana i ka wela mai ka ʻāpana ʻoki i ka wā e hana ai. aluminika.

I nā hihia ʻē aʻe, makemake ʻoe i ka conductivity haʻahaʻa. Mea paahana ʻoki keramika loaʻa pinepine haʻahaʻa thermal conductivity. Mālama kēia i ka wela i loko o ka chip a me ka mea hana, e pale ana i ke ʻano mea hana. Eia naʻe, ʻo ia hoʻi ke ʻano o ka seramika hiki i ka haʻalulu wela. Inā ʻoe e puhi i ka mea hoʻoheheʻe ma luna o kahi mea hoʻokomo seramika wela, hiki ke pohā e like me ke aniani wela i ka wai anuanu.

He mea kōkua ka hoʻomaopopo ʻana i kēia ke koho ʻana i ka mea hana ʻoki nā hoʻolālā—e like me ka pulu (me ka mea hoʻomaha) a maloʻo paha.

ʻO ka hoʻohālikelike ʻana i ke kumukūʻai kūʻai aku

Ma ke ʻano he mea hana o Hoʻokomo ʻia ʻo Carbide Cemented, Pono wau e wehewehe pinepine i nā mea hoʻolaha i ke kumu e uku ai ka mea hana i kāna hana.

Hiki i kekahi mea hana maʻamau ke hoʻohana i ka palaoa coarser tungsten carbide. ʻOi aku ke kumukūʻai. Hoʻohana ʻia kahi hāmeʻa premium i ka sub-micro grain carbide me 12% cobalt a me kahi multi-layer nano-coating. Hiki ke kūʻai ʻia ka mea hana premium he 30% ʻoi aʻe akā he 300% ka lōʻihi.

No ka mea nā hana mīkini kahi i uku nui ai ka manawa hoʻohaʻahaʻa (e like me ka laina hana automated nui), ʻo ka mea hana pipiʻi ke koho ʻoi aku ka haʻahaʻa. Eia naʻe, no kahi hale kūʻai liʻiliʻi e hana ana i ka hoʻoponopono hoʻokahi, ʻo ka ʻoki kiʻekiʻe ʻoi aku ka nui o ka hana ʻana o nā māka premium.

ʻO ka alakaʻi i ka mea hana ʻoki He mea maʻalahi ke kūʻai: e helu i ke kumukūʻai no kēlā me kēia ʻāpana, ʻaʻole ke kumukūʻai no ka mea hana.

Hōʻuluʻulu manaʻo: ʻO nā mea nui no ke koho ʻana i nā mea hana ʻoki

Ke hoʻokele nei i ka honua o ʻoki mea hoʻokomo a hiki ke paʻakikī nā mea hana paʻa. Eia nā mea nui e hoʻomanaʻo mai kēia alakaʻi.

• ʻO Cemented Carbide ka mōʻī: Hāʻawi ia i ke koena maikaʻi loa o paakiki a me ka paakiki no 80% o ʻoki noi.
• Hoʻohālikelike i ka mea: E hoʻohana i ka PCD no mea hao ole like aluminika. E hoʻohana i ka CBN no nā kila paʻakikī. E hoʻohana i nā seramika no nā superalloys.
• Hooponopono wela: Nā wela kiʻekiʻe pepehi mea paahana. E koho i na mea me ka pono ʻoʻoleʻa wela a ka hoʻoheheʻe wela.
• ʻO nā mea uhi: Titanium nitride a me nā uhi PVD/CVD ʻē aʻe e hoʻonui nui ʻia ola mea paahana ma ka hoʻemi ʻana i ka friction a me ka pale ʻana i ka wela.
• Kumukuai vs. Waiwai: Mai nānā wale i ke kumu kūʻai. A ʻoki ʻoki ʻoi ʻoi aku ka lōʻihi o ka hoʻemi ʻana i ka manawa o ka mīkini a me ka uku o ka ʻōpala.
• Loaʻa iā HSS kahi Niche: Mai hoemi kiʻekiʻe-wikiwiki kila no nā hoʻonohonoho paʻa ʻole a i ʻole nā mīkini kahiko kahi ʻoʻoleʻa kuʻi wikiwiki.

Ma Drillstar, ua kūpaʻa mākou e kōkua iā ʻoe e ʻike i ka mea ʻoki pono no ka hana. Inā makemake ʻoe i ka maʻamau Mīkini Mīkini Mīkini Drill Bit nā hoʻonā a i ʻole nā kikoʻī carbide maʻamau, ʻo ka hoʻomaopopo ʻana i ka ʻepekema o ka mea ʻo ia ka hana mua i ka holomua mīkini.
