ʻEhia mau ʻano o ka mīkini aniani i loko o ka mīkini CNC a ma ke kahua o ka hoʻohana pono?
Huli:ʻO kēia kaʻina hana ka hoʻololi ʻana i kahi mea hana ma ka lathe a ʻo ka mea ʻoki ʻoki e wehe i nā mea e hana i ke ʻano cylindrical. Hoʻohana maʻamau ia no ka hana ʻana i nā mea cylindrical e like me nā shafts, pins, a me nā bushings.
Milling:ʻO ka Milling kahi kaʻina e hoʻoneʻe ai kahi mea hana ʻoki ʻoki i nā mea mai kahi mea hana paʻa e hana i nā ʻano like ʻole, e like me nā ʻili palahalaha, nā kau, a me nā hiʻohiʻona 3D paʻakikī. Hoʻohana nui ʻia kēia ʻenehana i ka hana ʻana i nā ʻāpana no nā ʻoihana e like me aerospace, automotive, a me nā mea lapaʻau.
wili ʻia:Hoʻohana ʻia ka huila abrasive e hoʻopau i nā mea mai kahi mea hana. ʻO kēia kaʻina hana i ka hoʻopau ʻana i ka ʻili maʻemaʻe a hōʻoia i ka pololei o ke ana. Hoʻohana maʻamau ia i ka hana ʻana i nā mea kikoʻī kiʻekiʻe e like me nā bearings, gears, a me nā mea hana.
Ka wili ʻana:ʻO ka wili ʻana ke ʻano o ka hana ʻana i nā lua i loko o kahi mea hana me ka hoʻohana ʻana i kahi mea hana ʻoki ʻoki. Hoʻohana ʻia ia i nā noi like ʻole, me ka hana ʻana i nā poloka mīkini, nā ʻāpana aerospace, a me nā pā uila.
ʻO ka mīkini hoʻolele uila (EDM):Hoʻohana ʻo EDM i nā hoʻokuʻu uila e hoʻopau i nā mea mai kahi mea hana, hiki ke hana i nā ʻano paʻakikī a me nā hiʻohiʻona me ka pololei kiʻekiʻe. Hoʻohana maʻamau ia i ka hana ʻana i nā mold injection, make-casting dies, a me nā ʻāpana aerospace.
He ʻokoʻa nā noi kūpono o ka mīkini aniani i ka mīkini CNC. Hoʻopili ia i ka hana ʻana o nā ʻāpana no nā ʻoihana like ʻole e like me ka aerospace, automotive, nā mea lapaʻau, uila, a me nā mea kūʻai aku. Hoʻohana ʻia kēia mau kaʻina hana e hana i nā ʻāpana ākea, mai nā shafts maʻalahi a me nā brackets i nā ʻāpana aerospace paʻakikī a me nā implants olakino.
ʻO ka hana aniani e pili ana i ka ʻoiaʻiʻo e hiki i ka ʻili i hana ʻia ke hōʻike i ke kiʻi e like me ke aniani. Ua loaʻa kēia pae i kahi ʻano maikaʻi maikaʻi loa no kaʻāpana mīkini. ʻAʻole hiki i ka hana aniani ke hana i kahi hiʻohiʻona kiʻekiʻe no ka huahana akā e hōʻemi i ka hopena notch a hoʻolōʻihi i ke ola luhi o ka mea hana. He mea koʻikoʻi nui ia i nā hale hui a me ka sila. Hoʻohana nui ʻia ka ʻenehana hana aniani polishing e hōʻemi i ka ʻili o ka ʻili o ka mea hana. Ke koho ʻia ke ʻano hana polishing no ka mea hana metala, hiki ke koho ʻia nā ʻano like ʻole e like me nā pono like ʻole. Eia kekahi mau ʻano hana maʻamau o ka ʻenehana hoʻoponopono aniani.
1. ʻO ka polishing mechanical kahi ʻano o ka polishing e pili ana i ka ʻoki ʻana a me ka hoʻololi ʻana i ka ʻili o kahi mea no ka wehe ʻana i nā hemahema a loaʻa kahi ʻili maʻemaʻe. Hoʻohana maʻamau kēia ʻano i ka hoʻohana ʻana i nā mea hana e like me nā ʻili pōhaku ʻaila, huila huluhulu, a me ka pepa one no ka hana lima. No nā ʻāpana kūikawā e like me ka ʻili o nā kino rotary, hiki ke hoʻohana ʻia nā mea kōkua e like me nā turntables. Ke koi ʻia ka maikaʻi o ka ʻili kiʻekiʻe, hiki ke hoʻohana ʻia nā ʻano wili maikaʻi loa a me ka polishing. ʻO ka hoʻohana ʻana i nā mea abrasive kūikawā i loko o kahi wai i loaʻa i nā abrasives, kaomi ʻia ma ka mea hana no ka holo kiʻekiʻe. Ke hoʻohana nei i kēia ʻenehana, hiki ke hoʻokō ʻia kahi ʻano ʻino o Ra0.008μm, e lilo ia i mea kiʻekiʻe loa ma waena o nā ʻano polishing like ʻole. Hoʻohana pinepine ʻia kēia ʻano hana i nā molds lens optical.
2. ʻO ka polishing kemika he hana ia e hoʻoheheʻe ai i nā ʻāpana convex microscopic o ka ʻili o kahi mea i loko o kahi ʻano kemika, e waiho ana i nā ʻāpana concave ʻaʻole i hoʻopaʻa ʻia a loaʻa i kahi ʻili pahee. ʻAʻole koi kēia ʻano i nā mea hana paʻakikī a hiki ke hoʻoliʻiliʻi i nā mea hana me nā ʻano paʻakikī ʻoiai ʻoi aku ka maikaʻi no ka poli ʻana i nā mea hana he nui i ka manawa like. ʻO ka paʻakikī nui i ka poli kemika ʻo ka hoʻomākaukau ʻana i ka slurry polishing. ʻO ka maʻamau, ʻo ka ʻeleʻele o ka ʻili i loaʻa ma ka poli kemika ma kahi o ʻumi micrometers.
3. ʻO ke kumu kumu o ka polishing electrolytic e like me ka polishing kemikal. Hoʻopili ia i ka hoʻoheheʻe koho ʻana i nā ʻāpana liʻiliʻi liʻiliʻi o ka ʻili o ka mea e maʻalahi ai. ʻAʻole like me ka polishing chemical, hiki i ka electrolytic polishing ke hoʻopau i ka hopena o ka hopena cathodic a hāʻawi i kahi hopena maikaʻi aʻe. ʻO ke kaʻina hana polishing electrochemical he ʻelua mau ʻanuʻu: (1) macroscopic leveling, kahi e hoʻoheheʻe ʻia ai ka huahana i hoʻoheheʻe ʻia i loko o ka electrolyte, e hoʻemi ana i ke ʻano geometric roughness o ka ʻili waiwai, a ʻoi aku ka Ra ma mua o 1μm; a me (2) micropolishing, kahi i palahalaha ai ka ili, ua polarized ka anode, a ua hoonuiia ka olinolino o ka ili, me ka emi o Ra malalo o 1μm.
4. ʻO ka hoʻolele ʻana i ke kani ultrasonic ke kau ʻana i ka mea hana i loko o kahi hoʻokuʻu abrasive a hoʻokomo ʻia i nā hawewe kani ultrasonic. ʻO ka nalu ke kumu o ka abrasive e wili a poni i ka ʻili o kaʻāpana cnc maʻamau. Hoʻohana ka mīkini kani kani i kahi ikaika macroscopic liʻiliʻi, kahi e pale ai i ka deformation o ka mea hana, akā hiki ke paʻakikī ke hana a hoʻokomo i nā mea hana pono. Hiki ke hoʻohui ʻia ka mīkini kani kani me nā ʻano kemika a i ʻole electrochemical. Ke noi ʻana i ka haʻalulu kani ultrasonic e hoʻoulu i ka hoʻonā kōkua i ka wehe ʻana i nā huahana i hoʻoheheʻe ʻia mai ka ʻili o ka mea hana. ʻO ka hopena cavitation o nā hawewe kani ultrasonic i loko o nā wai e kōkua pū i ke kaʻina hana corrosion a hoʻomaʻamaʻa i ka hoʻomālamalama ʻana o ka ʻili.
5. Hoʻohana ʻia ka wai hoʻoheheʻe kiʻekiʻe a me nā ʻāpana abrasive e holoi i ka ʻili o kahi mea hana no ka polishing. ʻO nā ʻano hana maʻamau e pili ana i ka abrasive jetting, ka wai wai, a me ka hydrodynamic grinding. Hoʻohana ʻia ka hydrodynamic grinding, e hoʻoneʻe ana i ka ʻenehana wai e lawe ana i nā ʻāpana abrasive i hope a i waho i ka ʻili o ka mea hana i ka wikiwiki. Hoʻokumu nui ʻia ka medium me nā pūhui kūikawā (nā mea like me ka polymer) me ke kahe maikaʻi ma nā kaomi haʻahaʻa, i hui pū ʻia me nā abrasives e like me nā pauka silicon carbide.
6. ʻO ka hoʻoliʻi aniani, ʻike ʻia hoʻi ʻo mirroring, magnetic grinding, a polishing, e pili ana i ka hoʻohana ʻana i nā abrasive magnetic e hana i nā pulupulu abrasive me ke kōkua o nā māla magnetic no ka wili a me ka hana ʻana i nā mea hana. Hāʻawi kēia ʻano hana i ka hana kiʻekiʻe kiʻekiʻe, ka maikaʻi maikaʻi, ka mana maʻalahi o nā kūlana hana, a me nā kūlana hana maikaʻi.
Ke hoʻohana ʻia nā abrasives kūpono, hiki i ka roughness ʻili ke hiki i Ra 0.1μm. He mea nui ia e hoʻomaopopo i ka hana ʻana i ka mold plastic, ʻokoʻa ka manaʻo o ka polishing mai nā koi polishing surface ma nā ʻoihana ʻē aʻe. ʻO ka mea kikoʻī, pono e ʻōlelo ʻia ka poli polū e like me ka hoʻopau ʻana i ke aniani, kahi e koi ai i nā koi kiʻekiʻe ʻaʻole wale ma ke kaʻina polishing ponoʻī akā ma luna o ka palahalaha o ka ʻili, ka maʻalahi, a me ka pololei geometric.
ʻO ka ʻokoʻa, pono ka hoʻoliʻiliʻi ʻana i ka ʻili i kahi ʻili ʻālohilohi. Hoʻokaʻawale ʻia ke kūlana o ka hana aniani i ʻehā mau pae: AO=Ra 0.008μm, A1=Ra 0.016μm, A3=Ra 0.032μm, A4=Ra 0.063μm. No ka mea, ʻo nā ʻano hana e like me ka electrolytic polishing, fluid polishing, a me nā mea ʻē aʻe e hakakā nei e hoʻomalu pono i ka pololei geometric oʻāpana wili CNC, a me ka maikaʻi o ka ili o ka chemical polishing, ultrasonic polishing, magnetic grinding a polishing, a me nā ʻano like ʻole paha e hoʻokō i nā koi, ʻo ka hoʻoili ʻana i nā aniani o nā mold precision e hilinaʻi nui ʻia i ka mechanical polishing.
Inā makemake ʻoe e ʻike hou aku a nīnau paha, e ʻoluʻolu e leka uila info@anebon.com.
Hoʻopili ʻo Anebon i kou manaʻoʻiʻo o "Ke hana ʻana i nā hopena o ke ʻano kiʻekiʻe a me ka hoʻoulu ʻana i nā hoaaloha me nā poʻe mai nā wahi a puni o ka honua", hoʻokomo mau ʻo Anebon i ka hoihoi o nā mea kūʻai aku e hoʻomaka me ka mea hana Kina no Kinaʻāpana hoʻoheheʻe alumini.
