Koho o nā meahana pono koho CNC

I kēia manawa, ʻo nā mea hana CNC e hoʻohana ākea ʻia me nā pono daimana, nā pono hana cubic boron nitride, nā mea hana pālolo, nā mea hana lole, nā pono hana a me nā pono kila kiʻekiʻe. Nui nā māka o nā mea hana ʻoki a me nā ʻano o kā lākou waiwai. helu ʻia nā papa inoa hana o nā pono hana like ʻole ma lalo. Pono e koho ʻia nā mea hana ʻoki no ka mīkini ʻana ʻo NC e like me ka workpiece a me ke ʻano o ka mīkini. Pono ke koho ʻana o nā mea hana ʻoki me ke kaʻina mea hana, ʻoki mea pono a me ka pāʻani mea hoʻokūkū, kuhikuhi nui i nā ʻano mechanical, nā waiwai kino a me nā waiwai kemika o ke kūlike ʻelua, i mea e loaʻa ai ke ola ʻoihana lōʻihi loa a me ka hana ʻoki nui loa.

1.Matching o ka mea hana ʻoki me nā pono mechanical o nā mea mīkini ka mea like me ka ʻoki ʻana i nā mea hana me nā pono mechanical o nā mea mīkini e kuhikuhi nui i ka hoʻopili ʻana o ka mea hana ʻoki me nā pono mechanical e like me ka ikaika, ka paʻakikī a me ka paʻakikī o nā mea hana. kūpono nā ʻano ʻenehana ʻokoʻa no nā mea hana ʻokoʻa. (1) ke kaʻina paʻakikī o nā mea pono hana: he mea hana daimana> mea hana boric boron nitride> mea hana ceramic> carbide> kila kiʻekiʻe. ʻO ke kaʻina ikaika o ke kūlou o nā mea pono hana:> kiʻekiʻe wikiwiki kila carbide> mea hana pālolo> kaimana a me ka cubic boron nitride mea hana. (3) ke kauoha o ka ʻoʻoleʻa o ka mea pono hana: ʻo ke kila kiʻekiʻe> karbida> cubic boron nitride, daimana a me nā mea hana pālolo. Pono e hoʻoponopono ʻia nā mea hana me ka paʻakikī nui me ka mea hana me ka ʻoʻoleʻa kiʻekiʻe. ʻO ka paʻakikī o nā mea pono e ʻoi aku ka kiʻekiʻe ma mua o ka paʻakikī o ka mea hana, koi ʻia ma luna o 60HRC. ʻOi aku ka paʻakikī o ka mea hana, ʻoi aku ka maikaʻi o ke kūpaʻa o ka ʻaʻa. Eia kahi laʻana, ke nui ka cobalt i ka carbide sima. hoʻonui, hoʻonui ka ikaika a me ka paʻakikī a hoʻemi ka paʻakikī, a kūpono ia no ka mīkini maʻamau. Ke emi ka maʻi o ka cobalt, piʻi ka paʻakikī a paʻa i ke kūpaʻa, a he kūpono ia no ka hoʻopau ʻana. ʻoki kiʻekiʻe kiʻekiʻe. ʻO ka hana wela kiʻekiʻe o nā mea hana ʻoki keramika e hiki ai iā lākou ke ʻoki i ka wikiwiki, ʻo 2 ~ 10 mau manawa ka wikiwiki ma mua o ka carbide.

2. ʻO nā pono hana ʻoki a me nā waiwai o ka mea hana a kūlike i nā pono hana me nā ʻano kino ʻokoʻa, e like me, conductivity mehana kiʻekiʻe a me nā wahi hoʻoheheʻe haʻahaʻa o nā pono kila kiʻekiʻe, kahi hoʻoheheʻe kiʻekiʻe a me ka hoʻonui haʻahaʻa o nā mea pāmahana. kiʻekiʻe conductivity mehana a me ka haahaa thermal hoʻonui o daimana mea paahana, etc., pono no ka aaioee i ka workpiece mea i kekahi. Ke machining i ka workpiece me ka maikaʻi maikaʻi thermal conductivity, ka mea paahana me ka maikaʻi mehana conductivity e pono e hoʻohana i ka ʻoki ana wela koke hohola a hoʻemi i ke ana wela. Ma muli o ka nui o ka conductivity mehana a me ka diffusivity pumehana, maʻalahi ka hoʻokuʻu ʻia o ke daimana mai ka hōʻoki ʻana i ka wela a ʻaʻole e hoʻopuka i ka deformation thermal nui, a he mea nui ia no nā pono hana mīkini pono me nā koi kūpono kiʻekiʻe kiʻekiʻe. ka mahana o nā pono hana like 'ole: mea hana daimana 700 ~ 8000C, mea hana PCBN 13000 ~ 15000C, c mea hana eramic 1100 ~ 12000C, TiC (N) base sementide carbide 900 ~ 11000C, WC kumu ultra-fine palaoa lepo pipili carbide 800 ~ 9000C, HSS 600 ~ 7000C. ʻO ke kauoha o ka conductivity pumehana o nā pono hana like ʻole: PCD> PCBN> WC i hoʻopaʻa ʻia karbida> TiC (N) kāpili pāheʻe> HSS> pālolo-a320 i hoʻokumu ʻia / ceramic > ʻO ka ceramic base Si3N4> PCD. ʻO ke kauoha o ke kūpale kūwaho kūwaho o nā mea pono hana like ʻole ʻo HSS> WC paʻa paʻa> si3n4-base ceramic> PCBN> PCD> TiC (N) paʻa paʻa paʻa> a1203-base pālolo.

3. ʻO ka pilikia pili like o ka ʻoki ʻana i nā mea hana a me ka waiwai kemika o ka mea hana me ka mea nui e pili ana i ka hoʻohālikelike ʻana i nā palena o ka waiwai kemika e like me ka pilina kemika, ka hopena kemika, ka diffusion a me ka hoʻopau ʻana o nā mea hana ʻoki a me nā mea hana. ʻOkoʻa ʻokoʻa nā kumuwaiwai o ka pono hana no ka hana ʻana i nā mea hana. (1) nā ʻano ʻoki āpau o nā mea hana mea pāmahana pāheʻe (a me ke kila) no PCBN> pālolo> carbonide sima> HSS. (2) ke ana wela kūpale o nā mea hana ʻoki like ʻole. Penei: ceramic> PCBN> carbide daimana> HSS. ʻO ka ikaika diffusion o ka mea ʻoki (no ke kila) ʻo ia: daimana> pālolo si3n4-base> PCBN> a1203-kumu pālolo. ʻO ka ikaika diffusion (i ka titanium) he a1203- pālolo kumu> PCBN> SiC> Si3N4> daimana.
4. ʻO ka ʻōlelo maʻamau, PCBN, nā mea hana pālolo, kapa ʻia ka carbide a me nā pono hana TiCN kumu kūpono no ka hana mana helu o ka ferrous.
