ʻO ke ʻano hoʻoliʻiliʻi o ka poʻi ʻilika

Ka poni mīkini

ʻO ka polishing mechanical kahi ʻano polishing e hilinaʻi ana i ka ʻokiʻoki a me ka deformation plastic o ka ʻili waiwai e wehe i nā ʻāpana convex i poni ʻia e loaʻa ai kahi ʻili maʻemaʻe.ʻO ka mea maʻamau, hoʻohana ʻia nā lāʻau pōhaku ʻaila, huila huluhulu, sandpaper, etc., a ʻo ka hana lima ke ʻano nui.Hiki ke hoʻohana ʻia nā ʻāpana kūikawā e like me ka ʻili o ke kino holo.Ke hoʻohana nei i nā mea hana kōkua e like me nā turntables, hiki ke hoʻohana ʻia ka ultra-precision polishing no ka poʻe me nā koi kiʻekiʻe.ʻO ka Ultra-precision polishing ka hoʻohana ʻana i nā mea hana abrasive kūikawā, i kaomi paʻa ʻia ma luna o ka ʻili i hana ʻia o ka mea hana i loko o ka wai polishing i loaʻa nā abrasives no ka hoʻololi wikiwiki.Ke hoʻohana nei i kēia ʻenehana, hiki ke hoʻokō ʻia ka ʻili o Ra0.008μm, ʻo ia ka mea kiʻekiʻe loa ma waena o nā ʻano polishing like ʻole.Hoʻohana pinepine ʻia kēia ʻano hana i nā ʻano lens lens.

ʻO ka poʻi kemika

ʻO ka polishing kemika ka mea e hoʻoheheʻe ʻia ai ka ʻāpana microscopic convex o ka mea i loko o ke ʻano kemika ma mua o ka ʻāpana concave, i mea e loaʻa ai kahi ʻili laulima.ʻO ka pōmaikaʻi nui o kēia ʻano hana, ʻaʻole ia e koi i nā mea hana paʻakikī, hiki ke hoʻopololei i nā mea hana me nā ʻano paʻakikī, a hiki ke hoʻoliʻi i nā mea hana he nui i ka manawa like, me ka hana kiʻekiʻe.ʻO ka pilikia nui o ka polishing kemikal ka hoʻomākaukau ʻana i ka wai polishing.ʻO ka ʻeleʻele o ka ʻili i loaʻa ma ka poli kemika he 10 μm.

Electrolytic polishing

ʻO ke kumu kumu o ka polishing electrolytic ua like ia me ka polishing kemika, ʻo ia hoʻi, ma ke koho ʻana i nā protrusions liʻiliʻi ma luna o ka ʻili o ka mea e hoʻomaʻamaʻa i ka ʻili.Ke hoʻohālikelike ʻia me ka polishing chemical, hiki ke hoʻopau ʻia ka hopena o ka hopena cathode, a ʻoi aku ka maikaʻi o ka hopena.Hoʻokaʻawale ʻia ke kaʻina hana polishing electrochemical i ʻelua mau ʻanuʻu: (1) Macroscopic leveling ʻO nā huahana i hoʻoheheʻe ʻia i loko o ka electrolyte, a ke emi nei ka ʻeleʻele geometric o ka ʻili waiwai, Ra> 1μm.⑵ Haʻahaʻa-mālamalama pae: Anode polarization, ili olinolino ua hoʻomaikaʻi, Ra<1μm.

Ultrasonic polishing

E kau i ka mea hana i loko o ka abrasive suspension a hoʻokomo pū i loko o ke kahua kani ultrasonic, e hilinaʻi ana i ka hopena oscillation o ke kani ultrasonic, no laila e hoʻoneʻe ʻia ka abrasive a hoʻonani ʻia ma ka ʻili o ka mea hana.ʻO ka mīkini kani kani he liʻiliʻi macroscopic ikaika a ʻaʻole ia e hoʻoneʻe i ka mea hana, akā paʻakikī ke hana a hoʻokomo i nā mea hana.Hiki ke hoʻohui ʻia ka hana kani kani me nā ʻano hana kemika a electrochemical.Ma ke kumu o ka corrosion solution a me ka electrolysis, hoʻohana ʻia ka vibration ultrasonic e hoʻoulu i ka hopena, i hoʻokaʻawale ʻia nā huahana i hoʻoheheʻe ʻia ma ka ʻili o ka mea hana, a ʻo ka corrosion a i ʻole electrolyte kokoke i ka ʻili he ʻano like;ʻO ka hopena cavitation o ke kani ultrasonic i loko o ka wai hiki ke kāohi i ke kaʻina hana corrosion a maʻalahi i ka hoʻomālamalama ʻana o ka ʻili.

ʻO ka poli wai

Ke hilinaʻi nei ka wai polishing i ka wai kahe nui a me nā ʻāpana abrasive i lawe ʻia e ia e holoi i ka ʻili o ka mea hana e hoʻokō ai i ke kumu o ka polishing.ʻO nā ʻano hana maʻamau: ka hoʻoili ʻana i ka jet abrasive, ka hoʻoili ʻana i ka wai jet, hydrodynamic grinding a pēlā aku.Hoʻoikaika ʻia ka wili hydrodynamic e ke kaomi hydraulic e hoʻoheheʻe ʻia ka ʻenehana wai e lawe ana i nā ʻāpana abrasive i hope a i waho ma ka ʻili o ka mea hana i ka wikiwiki kiʻekiʻe.Hana ʻia ka medium me nā pūhui kūikawā (polymer-like substances) me ka flowability maikaʻi ma lalo o ke kaomi haʻahaʻa a hui pū ʻia me nā abrasives.Hiki ke hana ʻia nā abrasives me ka pauka carbide silika.

ʻO ka wili ʻana a me ka polishing magnetic

ʻO ka poli abrasive magnetic ka hoʻohana ʻana i nā abrasive magnetic e hana i nā pulupulu abrasive ma lalo o ka hana a kahi kahua magnetic e wili ai i ka mea hana.Loaʻa i kēia ʻano ka hana kiʻekiʻe o ka hana, ka maikaʻi maikaʻi, ka mana maʻalahi o nā kūlana hana a me nā kūlana hana maikaʻi.Ke hoʻohana nei i nā abrasives kūpono, hiki i ka roughness ili ke hiki i Ra0.1μm.2 Mechanical polishing e pili ana i kēia ʻano ʻO ka polishing i ʻōlelo ʻia i ka hana ʻana i nā mold plastic he ʻokoʻa loa ia mai ka poli ʻili i koi ʻia i nā ʻoihana ʻē aʻe.ʻO ka'ōlelo koʻikoʻi, pono e kapaʻia ka polishing o ka mold i ka hana aniani.ʻAʻole wale ia i nā koi kiʻekiʻe no ka polishing iā ia iho, akā loaʻa nō hoʻi nā kūlana kiʻekiʻe no ka palahalaha o ka ʻili, ka maʻalahi a me ka pololei geometric.ʻO ka hoʻoliʻiliʻi ʻana i ka ʻili ma ke ʻano maʻamau e koi wale i kahi ʻili mālamalama.Hoʻokaʻawale ʻia ka maʻamau o ka hana aniani ili i ʻehā mau pae: AO=Ra0.008μm, A1=Ra0.016μm, A3=Ra0.032μm, A4=Ra0.063μm.He mea paʻakikī ke kāohi pololei i ka pololei geometric o nā ʻāpana ma muli o nā ʻano e like me ka electrolytic polishing a me ka wai polishing.Eia nō naʻe, ʻaʻole i kūpono ka maikaʻi o ka ʻili o ka chemical polishing, ultrasonic polishing, magnetic abrasive polishing a me nā ʻano hana ʻē aʻe, no laila ʻo ka hoʻoili ʻana i nā aniani o nā mold precision ka nui o ka mechanical polishing.
