Dawb fused alumina yog cov khoom siv dav siv hauv kev sib tsoo thiab polishing. Nws muaj cov hardness siab, ruaj khov txiav kev ua tau zoo, thiab tus kheej zoo heev -sharpening muaj peev xwm, ua rau nws haum rau ob qho tib si ntxhib machining thiab precision xov. Hauv kev lag luam thoob ntiaj teb, nws kuj yog feem ntau hu uadawb aluminium oxide, tshwj xeeb tshaj yog nyob rau hauv industrial procurement thiab technical documentation.
Kev ua tau zoo ntawm dawb fused aluminais feem ntau txiav txim siab los ntawm grit loj, uas ncaj qha cuam tshuam rau kev ua haujlwm ntawm kev txiav thiab nto tiav. Nws feem ntau muab faib ua F series (F4–F240) thiab micro hmoov W series (W63–W0.5). Qhov tsawg dua tus naj npawb, lub coarser cov nplej; qhov loj tus naj npawb, qhov finer lub abrasive.
1. Grit Size Classification Overview
Coarse qib ntawm dawb txhuas oxide (F4-F14) yog tsim los rau hnyav Tshuag tshem tawm thiab ntxhib sib tsoo. Lawv feem ntau yog siv rau steel billets, castings, pob zeb leveling, thiab lwm yam siab - efficiency machining hauj lwm. Qhov ntau yam no tsom mus rau kev tshem tawm cov ntaub ntawv sai dua li qhov zoo ntawm qhov chaw.
Nruab nrab grit dawb aluminium oxide (F14-F30) yog siv dav hauv kev sib tsoo. Nws yog tsim rau deburring, weld tu, txiav ntug xov, thiab ntxhib nto npaj ntawm hlau thiab pob zeb cov ntaub ntawv.
Nruab nrab- qib zoo (F30–F60) feem ntau yog siv rau hauv ib nrab- cov txheej txheem tiav xws li kev sib tsoo nto, sib tsoo cylindrical, thiab cov cuab yeej ua ntej- ua tiav. Nyob rau theem no, dawb aluminium oxide pab txhim kho qhov sib xws ntawm qhov chaw thaum tswj kev ua haujlwm ruaj khov.
Fine grit dawb txhuas oxide (F60-F100) yog siv rau precision sib tsoo daim ntaub ntawv nrog rau cov cuab yeej sharpening, iav tiav, thiab pwm ua. Nws muab smoother nto zoo thiab zoo dua dimensional raug.
Micro hmoov dawb txhuas oxide (W63–W0.5) yog tsim los rau ultra- polishing zoo thiab daim iav tiav. Nws yog dav siv nyob rau hauv optical Cheebtsam, precision pwm, thiab siab -kawg hlau nto kho qhov twg tsis tshua muaj nto roughness yuav tsum tau.
2. Daim ntawv thov ntau los ntawm Grit Loj
Nyob rau hauv cov ntaub ntawv siv tau, dawb fused alumina saum F4 feem ntau yog siv rau hnyav -lub luag haujlwm ntxhib sib tsoo qhov twg cov khoom loj yuav tsum tau tshem tawm. F14-F30 ntau yam yog feem ntau siv nyob rau hauv kev tsim khoom rau kev deburring, vuam ntxuav, thiab ntxhib shaping. F30–F60 ntau yog haum rau ib nrab- cov txheej txheem tiav uas xav tau kev tswj kom zoo dua thiab txo qhov roughness. F60-F100 ntau yog siv dav hauv precision machining qhov chaw zoo thiab qhov tseeb yog qhov tseem ceeb. Micro hmoov qib (W series) yog siv rau qhov kawg polishing thiab daim iav tiav hauv high{13}}kawg industries.
Thoob plaws tag nrho cov theem no, dawb fused alumina muab kev ua haujlwm ruaj khov, ua rau nws haum rau ntau yam kev sib tsoo daim ntawv thov los ntawm kev ua haujlwm ntxhib mus rau ultra-precision finishing.
3. Qhov tseem ceeb ntawm kev xaiv Grit
Xaiv qhov tseeb dawb fused alumina grit loj yog qhov tseem ceeb rau kev ua tiav qhov xav tau sib npaug ntawm qhov ua tau zoo thiab qhov zoo. Coarser grits txhim kho cov ntaub ntawv tshem tawm ceev, thaum finer grits txhim kho nto tiav thiab raug. Kev xaiv kom raug kuj yuav pab txo qis kev tsim hluav taws xob, txhim kho lub neej ntawm cov cuab yeej, thiab tiv thaiv kev puas tsuaj ntawm cov khoom thaum lub sij hawm sib tsoo.
