ʻIke o Tungsten Carbide End Mills a me kona hiki ʻole ke kūlana

Hana ʻia nā wili hope me ka carbide?

Hana ʻia ka hapa nui o nā wili hope mai nā ʻāpana kila cobalt - i kapa ʻia ʻo HSS (High Speed ​​Steel), a i ʻole mai ka tungsten carbide. ʻO ke koho ʻana o nā mea o kāu wili hope i koho ʻia e pili ana i ka paʻakikī o kāu mea hana a me ka wikiwiki o ka spindle o kāu mīkini.

He aha ka wili hope paʻakikī?

ʻO nā wili hope carbide.

ʻO nā wili hope ʻo Carbide kekahi o nā mea hana ʻoki paʻakikī loa i loaʻa. Ma hope o daimana he kakaikahi loa nā mea ʻoi aku ka paʻakikī ma mua o ka carbide. ʻO kēia ka mea e hiki ai i ka carbide ke hana i nā metala ke hana pololei. Hāʻule ka Tungsten Carbide ma waena o 8.5 a me 9.0 ma ka pālākiō paʻakikī o Moh, e like me ka paʻakikī e like me ke daimana.

He aha ka mea wili hope maikaʻi loa no ke kila?

ʻO ka mea nui, ʻoi aku ka maikaʻi o nā wili hope carbide no ke kila a me kāna mau mea hoʻohui no ka mea ʻoi aku ka nui o ka conductivity thermal a hana maikaʻi no nā metala paʻakikī. Hoʻohana pū ʻo Carbide i ka wikiwiki kiʻekiʻe, ʻo ia ka mea hiki i kāu mea ʻoki ke kū i nā mahana kiʻekiʻe a hiki ke pale i ka ʻaʻahu a me ka waimaka. Ke hoʻopau ʻana i nā ʻāpana kila kila, pono ka helu ohe kiʻekiʻe a/a i ʻole helix kiʻekiʻe no nā hopena maikaʻi loa. ʻO ka hoʻopau ʻana i nā wili hope no ke kila kila e loaʻa kahi kihi helix ma luna o 40 degere, a me ka helu ohe he 5 a ʻoi aku paha. No nā ala paahana hoʻopau koʻikoʻi, hiki ke helu ʻia ka helu ohe mai ka 7 ohe a hiki i ka 14 kiʻekiʻe.

ʻO wai ka mea ʻoi aku ka maikaʻi ， HSS a i ʻole carbide end mill?

Hāʻawi ʻo Solid Carbide i ka rigidity ʻoi aku ka maikaʻi ma mua o ke kila kiʻekiʻe (HSS). He pale wela loa ia a hoʻohana ʻia no nā noi wikiwiki kiʻekiʻe ma luna o ka hao hao, nā mea nonferrous, nā plastics a me nā mea paʻakikī i ka mīkini. Hāʻawi nā wili hope Carbide i ka ʻoi aku o ka rigidity a hiki ke holo 2-3X wikiwiki ma mua o HSS.

No ke aha e hāʻule ai nā wili hope?

1. Holo wikiwiki a lohi pahaHiki ke hoʻopili i ke ola mea hana.

ʻO ka holo wikiwiki ʻana i kahi hāmeʻa hiki ke hoʻoulu i ka nui o ka chip suboptimal a i ʻole ka hemahema o ka hāmeʻa pōʻino. ʻO ka mea ʻē aʻe, hiki i ka RPM haʻahaʻa ke hopena i ka deflection, hoʻopau maikaʻi ʻole, a i ʻole ka hoʻemi ʻana i nā helu wehe metala.

2. ʻO ka hānai liʻiliʻi a nui loa paha.

ʻO kekahi hiʻohiʻona koʻikoʻi o ka wikiwiki a me nā meaʻai, ʻokoʻa ka helu hānai maikaʻi loa no kahi hana ma muli o ke ʻano mea hana a me nā mea hana. Inā holo ʻoe i kāu hāmeʻa me ka lohi loa o ka helu hānai, holo ʻoe i ka pilikia o ka ʻoki hou ʻana i nā ʻāpana a me ka hoʻopale ʻana i ka mea hana. Inā holo ʻoe i kāu hāmeʻa me ka wikiwiki o ka helu hānai, hiki iā ʻoe ke hana i ka haʻihaʻi mea hana. He ʻoiaʻiʻo kēia me nā mea hana liʻiliʻi.

3. Ka hoʻohana ʻana i ka ʻāpala kuʻuna.

ʻOiai he mea pono a ʻoi aku ka maikaʻi o ka roughing kuʻuna, ʻoi aku ka haʻahaʻa i ka High Efficiency Milling (HEM). ʻO HEM kahi ʻenehana hoʻoheheʻe e hoʻohana ana i kahi Radial Depth of Cut (RDOC) haʻahaʻa a me kahi Axial Depth of Cut (ADOC) kiʻekiʻe. Hoʻolaha kēia i ka ʻaʻahu ma waena o ka ʻoki ʻoki, hoʻopau i ka wela, a hōʻemi i ka hiki ʻole o ka hāmeʻa. Ma waho aʻe o ka hoʻonui nui ʻana i ke ola mea hana, hiki i ka HEM ke hana i kahi hoʻopau maikaʻi aʻe a ʻoi aku ka kiʻekiʻe o ka lawe ʻana i ka metala, e lilo ia i mea hoʻoikaika maikaʻi a puni kāu hale kūʻai.

4. Ke hoʻohana ʻana i ka paʻa ʻana i nā mea hana pono ʻole a me kona hopena i ke ola o nā mea hana.

He emi ka hopena o nā ʻāpana holo kūpono i nā kūlana paʻa mea hana suboptimal. Hiki ke hoʻokuʻu ʻia ka mea hana, huki ʻia, a me nā ʻāpana ʻoki ʻia ma ka pili ʻana o ka mīkini-i-mea hana maikaʻi ʻole. ʻO ka ʻōlelo maʻamau, ʻoi aku ka nui o nā wahi e pili ana i kahi mea paʻa me ka shank too l, ʻoi aku ka paʻa o ka pilina. Hāʻawi nā mea paʻa hydraulic a me nā mea paʻa paʻa i ka hoʻonui ʻana i ka hana ma luna o nā ʻano hana hoʻopaʻa mīkini, e like me kekahi mau hoʻololi shank.

5. ʻAʻole hoʻohana i ka Helix/Pitch Geometry.

ʻO kahi hiʻohiʻona ma nā ʻano wili hope hana kiʻekiʻe, helix variable, a i ʻole pitch variable, geometry he hoʻololi maʻalahi i ka geometry wili hope maʻamau. ʻO kēia hiʻohiʻona geometrical e hōʻoia i ka ʻokoʻa o ka manawa ma waena o nā hoʻopili ʻoki ʻoki me ka ʻāpana hana, ʻaʻole i ka manawa like me kēlā me kēia hoʻololi mea hana.Hoʻemi kēia ʻano hoʻololi i ke kamaʻilio ʻana ma o ka hōʻemi ʻana i nā harmonics, ka mea e hoʻonui ai i ke ola mea hana a hoʻopuka i nā hopena ʻoi aku ka maikaʻi.

6. Ke koho ʻana i ka uhi hewa hiki ke hoʻohana i ke ola mea hana.

ʻOiai ʻoi aku ka liʻiliʻi o ke kumukūʻai, hiki i kahi mea hana me kahi uhi i hoʻopaʻa ʻia no kāu mea hana hana hiki ke hoʻololi i nā mea āpau. Hoʻonui ka nui o nā uhi i ka lubricity, hoʻolōʻihi i ka hoʻohana ʻana i nā mea hana kūlohelohe, aʻo nā mea ʻē aʻe e hoʻonui i ka paʻakikī a me ke kūpaʻa abrasion. Eia nō naʻe, ʻaʻole kūpono nā uhi āpau i nā mea āpau, a ʻike ʻia ka ʻokoʻa i nā mea ferrous a me nā mea ʻole. No ka laʻana, hoʻonui ka paʻakikī o ka paʻakikī a me ke kūpaʻa wela o ka alumini Titanium Nitride (AlTiN) i loko o nā mea ferrous, akā he pili kiʻekiʻe i ka alumini, e hoʻopili ai ka ʻāpana hana i ka mea ʻoki. ʻO ka uhi ʻana o Titanium Diboride (TiB2), ma kekahi ʻaoʻao, he haʻahaʻa haʻahaʻa loa kona pili ʻana i ka alumini, a pale i ka ʻoki ʻana i ke kūkulu ʻana a me ka hoʻopili ʻana i nā chip, a hoʻonui i ke ola mea hana.

7. E hoʻohana ana i ka lōʻihi o ka ʻoki.

ʻOiai he mea pono loa ka lōʻihi lōʻihi o ka ʻoki ʻana (LOC) no kekahi mau hana, ʻoi aku hoʻi i ka hoʻopau ʻana i nā hana, hoʻemi ia i ka rigidity a me ka ikaika o ka mea ʻoki. Ma ke ʻano maʻamau, pono ka LOC o kahi mea paahana e like me ka lōʻihi e pono ai e hōʻoia i ka paʻa ʻana o ka hāmeʻa i ka nui o kāna substrate kumu e like me ka hiki. ʻOi aku ka lōʻihi o ka LOC o kahi mea hana, ʻoi aku ka maʻalahi o ka hoʻohuli ʻana, a laila e hoʻemi ana i kona ola pono hana a hoʻonui i ka manawa o ka haki.

8. Ke koho 'ana i ka Helu Ohe.

E like me ka maʻalahi e like me ka mea i ʻike ʻia, ʻo ka helu ʻohe o kahi mea hana he hopena pololei a kaulana i kāna hana a me nā ʻāpana holo. ʻO kahi mea hana me ka helu ʻohe haʻahaʻa (2 a 3) ʻoi aku ka nui o nā awāwa ʻōheʻe a me kahi kumu liʻiliʻi. E like me LOC, ʻo ka liʻiliʻi o ka substrate i koe ma kahi mea ʻoki ʻoki, ʻoi aku ka nāwaliwali a ʻoi aku ka paʻakikī. ʻO kahi mea hana me ka helu ohe kiʻekiʻe (5 a ʻoi aku paha) ʻoi aku ka nui o ke kumu. Eia naʻe, ʻaʻole ʻoi aku ka maikaʻi o ka helu ohe kiʻekiʻe. Hoʻohana mau ʻia nā helu ohe haʻahaʻa i nā mea alumini a me nā mea non-ferrous, ʻo ka mea ma muli o ka palupalu o kēia mau mea e hiki ai ke maʻalahi no ka hoʻonui ʻana i nā kumukūʻai metala, akā no ka waiwai o kā lākou chips. ʻO nā mea hao ʻole e hana pinepine i nā ʻāpana ʻoi aku ka lōʻihi, ʻoi aku ka ikaika a me ka helu o ka ʻohe haʻahaʻa e hōʻemi i ka ʻoki hou ʻana. Pono nā mea hana kiʻekiʻe o ka helu ohe no nā mea hao ʻoi aku ka paʻakikī, no ko lākou ikaika nui a no ka mea ʻoi aku ka hopohopo o ka ʻoki ʻana i ka chip no ka mea e hana pinepine kēia mau mea i nā ʻāpana liʻiliʻi.

Inā makemake ʻoe i nā huahana tungsten carbide a makemake ʻoe i ka ʻike hou aku a me nā kikoʻī, hiki iā ʻoeKĀHEA IĀ MĀ˚OUma ke kelepona a me ka leka ma ka hema, a i ʻoleE HOOHUNA MAI I KA LEKAma lalo o kēia ʻaoʻao.
