Resin bonded abrasives muaj xws li abrasive grains, resin binder, thiab additives. Cov nplej abrasive, xws li txhuas oxide lossis silicon carbide, yog cov neeg ua haujlwm txiav uas ua haujlwm sib tsoo. Resin binder ua haujlwm raws li cov kua nplaum uas tuav cov nplej ua ke. Nws yog ib qho hluavtaws polymer uas, thaum kho, ua kom muaj zog thiab hloov tau yooj yim.
Thaum lub sij hawm tsim cov txheej txheem, cov resin, abrasive grains, thiab additives yog ua tib zoo sib tov thiab ces molded nyob rau hauv tshav kub thiab siab. Cov resin kho nyob ib ncig ntawm cov nplej abrasive, tsim cov matrix uas tso cai rau cov nplej kom protrude thiab cuam tshuam nrog workpiece. Cov additives yog siv los hloov cov khoom xws li hardness, toughness, thiab kub tsis kam ntawm daim ntawv cog lus.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm resin bonded abrasives yog lawv lub peev xwm kom ua tiav qhov kev sib tsoo siab thiab ua kom tiav nto. Qhov yooj ntawm daim ntawv cog lus tso cai rau kev sib tsoo ntau dua, txo qhov kev pheej hmoo ntawm kev puas tsuaj thiab khawb. Qhov no ua rau lawv zoo tagnrho rau cov ntawv thov uas yuav tsum muaj qhov zoo nkauj zoo nkauj, xws li hauv kev tsim cov lenses, precision hlau qhov chaw, thiab semiconductor wafers.
Raws li cov nplej abrasive hnav thaum sib tsoo, cov resin daim ntawv cog lus maj mam tawg, nthuav tawm cov nplej tshiab, ntse. Qhov no tus kheej-sharpening mechanism pab tswj kev sib tsoo zoo ib yam thiab txo qhov kev xav tau ntawm kev hnav khaub ncaws ntawm cov cuab yeej sib tsoo. Nws kuj tseem ua kom ntseeg tau tias cov txiav quab yuam tseem nyob ruaj khov thoob plaws hauv txoj kev sib tsoo, txhim kho qhov zoo thiab ua haujlwm ntawm kev ua haujlwm.
Resin bonded abrasives tuaj yeem siv rau ntau yam ntaub ntawv, suav nrog hlau, ceramics, iav, thiab yas. Lawv tsim nyog rau kev sib tsoo sib txawv, xws li kev sib tsoo nto, sib tsoo cylindrical, thiab kev sib tsoo sab hauv. Piv txwv li, hauv kev lag luam tsheb, lawv tau siv rau kev sib tsoo lub tog raj kheej, camshafts, thiab nres rotors. Hauv kev lag luam ua cov hniav nyiaj hniav kub, lawv tau siv rau polishing thiab shaping precious hlau thiab gemstones.
