Manaʻo ka hapa nui o ke kila kila ʻaʻole e pala, ʻoiaʻiʻo, ua like ia me nā metala ʻē aʻe, e hoʻopili ʻia ka lima a i ʻole ka hoʻopili ʻana me ka ea i hoʻopili ʻia e ke kaiapuni e oxidized rust, ʻo ia hoʻi, ʻo ke kila kila kila ma hope o ka hana mechanical e like me ka welding, stamping, curling, wela wela a me nā kaʻina hana ʻē aʻe e hana i kahi papa o ka ʻeleʻele oxidation metamorphic hardening layer, I ka manawa like, ua ʻike ʻia nā maka liʻiliʻi. ʻO nā angle burrs, a me nā mea ʻē aʻe, he mea paʻakikī ke wehe ʻia e nā ʻano mechanical, e pili ana i ka pāʻani o nā ʻano o ka mea hana ponoʻī. I mea e hoʻoponopono ai i kēia mau pilikia, hoʻohana ka poʻe i nā ʻano hana like ʻole e wili a poli i nā ʻili metala e like me ke kila kila. I mea e hoʻoponopono ai i kēia mau pilikia, hoʻohana ka poʻe i nā ʻano hana like ʻole e wili a poli i nā ʻili metala e like me ke kila kila.

ʻili kila kilahoʻopaug - ka hoʻopololei ʻana

1.1Ka poni mīkini:ʻO ka polishing mīkini ma ka ʻoki ʻana, ka deformation plastic o ka ʻili o ka mea e wehe ai i ka ʻāpana convex i poni ʻia a loaʻa ke ʻano polishing maʻemaʻe, me ka hoʻohana pinepine ʻana i ka papa pōhaku keʻokeʻo, ka huila huluhulu, ka pepa, a me nā mea ʻē aʻe. ʻO ka hoʻopau ʻana i ka polishing ka hoʻohana ʻana i nā mea hana wili kūikawā, i loko o ka wai polishing i loaʻa i ka abrasive, paʻa paʻa i ka mea hana e hoʻohana ʻia i ka ʻili mīkini, no ka wikiwiki wikiwiki. Hiki ke hoʻokō ʻia ka roughness ʻili o Ra0.008μm ma ka hoʻohana ʻana i kēia ʻenehana, ʻo ia ka mea kiʻekiʻe loa ma waena o nā ʻano polishing like ʻole. Hoʻohana pinepine ʻia kēia ʻano hana i nā molds lens optical.

1.2ʻO ka poʻi kemika:ʻO ka polishing kemika ʻo ia ka hoʻoheheʻe ʻana i ka ʻāpana micro-convex o ka ʻili o ka mea i loko o ka ʻenekini kemika ma mua o ka ʻāpana concave, i loaʻa ai kahi ʻili maʻemaʻe. ʻO ka pōmaikaʻi nui o kēia ʻano hana, ʻaʻole ia e koi i nā mea hana paʻakikī, hiki ke hoʻolalelale i ka mea hana me ke ʻano paʻakikī, a hiki ke hoʻonani 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 roughness o ka ʻili i loaʻa e ka polishing kemikal ka maʻamau 10μm.

1.3Electrolytic polishing:ʻO ke kumu kumu o ka polishing electrolytic e like me ka polishing kemika, ʻo ia hoʻi, ma ka hoʻoheheʻe ʻana i nā ʻāpana liʻiliʻi liʻiliʻi ma 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) ka hoʻoheheʻe ʻana o ka huahana i hoʻoheheʻe ʻia i loko o ka electrolyte, ke emi nei ka geometric roughness o ka ʻili waiwai, a me Ra> 1μm. (2) Haʻahaʻa māmā pae anodic polarization, ili olinolino hoonui, Ra

1.4Ultrasonic polishing:Hoʻokomo ʻia ka mea hana i loko o ka hoʻokuʻu abrasive a hoʻokomo pū ʻia i loko o ke kahua kani ultrasonic, a ʻo ka abrasive ka lepo a hoʻonani ʻia ma ka ʻili o ka mea hana ma ka hilinaʻi ʻana i ka oscillation o ka hawewe kani ultrasonic. ʻAʻole liʻiliʻi ka ikaika o ka ultrasonic processing macroscopic, akā ʻoi aku ka paʻakikī o ka hana ʻana a me ka hoʻonohonoho ʻana. 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 haʻalulu kani ultrasonic e hoʻoulu i ka hopena, i hoʻokaʻawale ʻia nā huahana i hoʻoheheʻe ʻia ma ka ʻili o ka workpiece, a ʻo ka corrosion a i ʻole electrolyte kokoke i ka ʻili he ʻano like. Kani ultrasonic cavitation i loko o ka wai hiki no hoi inhibit ka corrosion kaʻina hana, i conducive i ka ili olinolino.

1.5ʻO ka poli wai: Ke hilinaʻi nei ka wai polishing i ke kahe kiʻekiʻe o ka wai a me kāna mau ʻāpana 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 jet wai, hydrodynamic grinding a pēlā aku. Hoʻoikaika ʻia ka wili hydrodynamic e ke kaomi hydraulic e hoʻoheheʻe ʻia ka wai e lawe ana i nā ʻāpana abrasive ma ka ʻili o ka mea hana i ka wikiwiki kiʻekiʻe. Hoʻohana nui ʻia ka medium me nā mea hoʻohui kūikawā (polymer-like substances) me ke kahe maikaʻi ma lalo o ke kaomi haʻahaʻa a hui pū ʻia me nā abrasives, hiki ke lilo i ka pauka silicon carbide.

1.6Mākēneki wili polishing:ʻO ka polishing magnetic ka hoʻohana ʻana i nā abrasives magnetic ma lalo o ka hana a nā māla magnetic e hana i kahi pulupulu abrasive e wili i ka mea hana. Loaʻa i kēia ʻano ka maikaʻi o ka hana kiʻekiʻe kiʻekiʻe, ka maikaʻi maikaʻi, ka mana maʻalahi o nā kūlana hana a me nā kūlana hana maikaʻi. Me ka abrasive kūpono, hiki i ka roughness ili ke hiki i Ra0.1μm.

ʻO nā kumu e pili ana i ka maikaʻi polishing o ka make No ka mea ua hoʻopau nui ʻia ka polishing mechanical e ka manual, ʻo ka ʻenehana polishing ke kumu nui o ka hoʻopili ʻana i ka maikaʻi polishing. Eia kekahi, pili ia i ka mea poni, ke ʻano o ka ʻili ma mua o ka polishing, a me ke kaʻina hana wela. ʻO ke kila kila kiʻekiʻe kahi mea e pono ai no ka maikaʻi polishing maikaʻi, inā ʻaʻole kūlike ka paʻakikī o ka ʻili kila a i ʻole he ʻokoʻa nā ʻano, hana pinepine i nā pilikia polishing. ʻAʻole kūpono nā ʻano inclusions a me nā pores i ke kila i ka polishing.

3.1 Ka hopena o ka paʻakikī like ʻole ma ke kaʻina polishing ʻO ka piʻi ʻana o ka paʻakikī e hoʻonui i ka paʻakikī o ka wili ʻana, akā e emi ana ka ʻala ma hope o ka polishing. Ma muli o ka piʻi ʻana o ka paʻakikī, ʻo ka manawa polishing e pono ai e hoʻokō i ka haʻahaʻa haʻahaʻa e piʻi like. I ka manawa like, piʻi ka paʻakikī, a ua hoʻemi ʻia ka hiki o ka polishing nui.

3.2 Ka hopena o ke ʻano o ka ʻili o ka mea hana ma ke kaʻina polishing I ke kaʻina ʻoki ʻana i ka mīkini ʻoki kila, e pōʻino ka ʻili e ka wela, ke koʻikoʻi kūloko a i ʻole nā ​​mea ʻē aʻe, a ʻo nā ʻokiʻoki kūpono ʻole e hoʻopili i ka hopena polishing. ʻOi aku ka paʻakikī o ka ʻili ma hope o ka EDM ma mua o ka ʻili ma hope o ka mīkini maʻamau a i ʻole ka hoʻomaʻamaʻa wela, no laila e hoʻopili maikaʻi ʻia ka EDM i ka lole EDM ma mua o ka pau ʻana o ka EDM, i ʻole e hana ka ʻili i kahi ʻāpana lahilahi paʻakikī. Inā ʻaʻole i koho maikaʻi ʻia nā pae hoʻomaʻemaʻe EDM, hiki i ka hohonu o ka pā wela wela ke piʻi i kahi kiʻekiʻe o 0.4mm. ʻOi aku ke kiʻekiʻe o ka paʻakikī o ka ʻāpana lahilahi paʻakikī ma mua o ka substrate a pono e wehe ʻia. No laila, ʻoi aku ka maikaʻi o ka hoʻohui ʻana i kahi kaʻina hana wili, wehe loa i ka ʻili o ka ʻili i hoʻopōʻino ʻia, a hana i ka awelika o ka ili metala, e hāʻawi ana i kumu maikaʻi no ka polishing.

ʻO ka polishing kemikal no nā koi polishing ʻaʻole ia he manawa kiʻekiʻe, pono e wela i ka hoʻohana ʻana i ka ʻenehana o kēia manawa, inā hiki iā ia ke hoʻohana i nā polishing ʻekolu i luna aʻe ʻaʻole e hoʻohana i ka polishing kemika, no ka mea ʻilihune ka hopena polishing kemika, ʻoi aku ka kiʻekiʻe o ke kumukūʻai.
