Hoʻokaʻawale ʻia ka ʻiʻo abrasive i ʻekolu mau ʻāpana: paʻa, waena a wehe.Hiki ke hoʻokaʻawale hou ʻia kēlā me kēia ʻāpana i nā helu, etc., i hoʻokaʻawale ʻia e nā helu hui.ʻO ka nui o ka helu hui o kamea hana abrasive, ka liʻiliʻi o ka pākēneka leo o ka abrasive i loko o kamea hana abrasive, a ʻoi aku ka nui o ka ʻokoʻa ma waena o nā ʻāpana abrasive, ʻo ia hoʻi, ʻoi aku ka palupalu o ka hui.ʻO ka liʻiliʻi o ka helu hui, ʻoi aku ka paʻa o ka hui.ʻAʻole maʻalahi nā abrasive me ka ʻiʻo maloʻo ke hoʻohana ʻia, a hoʻemi i ka wela i ka wā wili, hiki ke hōʻemi i ka deformation thermal a me ke ahi o ka mea hana.ʻAʻole maʻalahi ka hāʻule ʻana o nā ʻōpala abrasive o ka mea hana abrasive me ka hoʻonohonoho paʻa ʻana, he mea pono e mālama i ke ʻano geometric o ka mea hana abrasive.Hoʻoponopono wale ʻia ka hoʻonohonoho ʻana o ka mea hana abrasive e like me ke ʻano o ka mea hana abrasive i ka wā o ka hana ʻana, a ʻaʻole i ana ʻia.ʻO nā mea hoʻopaʻa hoʻopaʻa superabrasive i hana nui ʻia me ke daimana, cubic boron nitride, etc. a hoʻopaʻa ʻia me kahi mea hoʻopaʻa.Ma muli o ke kumu kūʻai kiʻekiʻe o ka daimana a me ka cubic boron nitride a me ke kūpaʻa maikaʻi ʻana, ʻokoʻa nā abrasives i hoʻopaʻa ʻia me lākou mai nā abrasives abrasive maʻamau.Ma waho aʻe o ka papa abrasive superhard, aia nā papa hoʻololi a me nā substrates.ʻO ka papa superabrasive ka ʻāpana e hoʻokani i kahi ʻokiʻoki, a ua haku ʻia me nā superabrasives a me nā mea hoʻopili.He mea kākoʻo ka matrix i ka wili ʻana a ua haku ʻia me nā mea e like me ka metala, ka bakelite a i ʻole nā ceramics.
ʻElua mau kaʻina hana no nā abrasives paʻa metala, pauka metallurgy a me ka electroplating, ka mea i hoʻohana nui ʻia no ka superhard abrasive bonded abrasives.Hoʻohana ke ʻano metallurgy pauka i ke keleawe e like me ka mea hoʻopili.Ma hope o ka hui ʻana, hoʻokumu ʻia e ka paʻi wela a i ʻole ke kaomi ʻana i ke ana wela, a laila sintered.Ke hoʻohana nei ke ʻano electroplating i ka nickel a i ʻole nickel-cobalt alloy e like me ke metala electroplating, a hoʻohui ʻia ka abrasive ma luna o ka substrate e like me ke kaʻina hana electroplating e hana i kahi mea hana abrasive.ʻO nā ʻano ʻano abrasive kūikawā ʻo ia nā mea abrasive corundum sintered a me nā abrasives fiber.Hana ʻia ka mea hana abrasive corundum sintered ma ka hui ʻana, ka hana ʻana, a me ka sintering ma kahi o 1800 ℃ me ka pauka alumina maikaʻi a me ka nui o ka chromium oxide.ʻO kēia ʻanomea hana abrasiveLoaʻa i kahi hoʻolālā paʻa a me ka ikaika kiʻekiʻe, a hoʻohana nui ʻia no ka hoʻoponopono ʻana i nā uaki, nā mea kani a me nā ʻāpana ʻē aʻe.Hana ʻia nā mea hana abrasive fiber me nā filament fiber (e like me nā filament nylon) i loaʻa a pili paha i nā abrasives.Loaʻa iā lākou ka elasticity maikaʻi a hoʻohana nui ʻia no ka polishing mea metala a me kā lākou huahana.
Hoʻohana ʻia ka papa hoʻololi no ka hoʻopili ʻana i ka matrix a me ka papa superabrasive, a ua haku ʻia me kahi mea hoʻopili, hiki ke haʻalele ʻia i kekahi manawa.ʻO nā mea hoʻopaʻa maʻamau i hoʻohana ʻia he resins, metals, plated metals a me ceramics.
ʻO ke kaʻina hana o nā abrasive i hoʻopaʻa ʻia me: ka hāʻawi ʻana, ka hui ʻana, ka hana ʻana, ka mālama wela, ka hana ʻana a me ka nānā ʻana.Me nā mea paʻa like ʻole, ʻokoʻa ke kaʻina hana.ʻO ka paʻa seramikamea hana abrasive hoʻohana nui i ke ʻano kaomi.Ma hope o ke kaupaona ʻana i ka abrasive a me ka mea hoʻopaʻa e like me ka ratio kaumaha o ke ʻano, e hoʻokomo i loko o ka mixer e hui like, e hoʻokomo i loko o ka moʻo metala, a hoʻohālikelike i ka mea hana abrasive blank ma ka paʻi.Hoʻomaloʻo ʻia ka blank a laila hoʻouka ʻia i loko o ke kiln no ka ʻala ʻana, a ʻo ka wela o ke ahi ma kahi o 1300 °C.Ke hoʻohana ʻia kahi mea hoʻoheheʻe hoʻoheheʻe haʻahaʻa, ʻoi aku ka haʻahaʻa o ka sintering ma mua o 1000°C.A laila hoʻoponopono pololei ʻia e like me ka nui a me ke ʻano i ʻōlelo ʻia, a ma hope ke nānā ʻia ka huahana.Hoʻokumu pinepine ʻia nā abrasives i hoʻopaʻa ʻia i ka Resin ma kahi paʻi ma ka lumi wela, a aia pū kekahi mau kaʻina hana wela e hoʻomehana ʻia a kaomi ʻia ma lalo o nā kūlana hoʻomehana.Ma hope o ka hoʻoheheʻe ʻia ʻana, hoʻopaʻakikī ʻia i loko o kahi umu paʻakikī.Ke hoʻohana ʻia ka resin phenolic ma ke ʻano he binder, ʻo ka mahana hoʻōla ʻo 180 ~ 200 ℃.Hoʻohui nui ʻia nā mea abrasive i hoʻopaʻa ʻia i ka Rubber me nā wili, ʻōwili ʻia i loko o nā ʻāpana lahilahi, a laila ʻoki ʻia me nā pahi kuʻi.Ma hope o ka hoʻoheheʻe ʻana, ua vulcanized i loko o kahi pahu vulcanization ma kahi mahana o 165 ~ 180 ℃.
