Muaj ntau hom kev sib tsoo log, thiab lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg. Vim qhov sib txawv abrasives, binder cov ntaub ntawv thiab cov txheej txheem ntawm kev sib tsoo log, ntau yam sib tsoo log muaj kev ua haujlwm sib txawv. Txhua hom kev sib tsoo log muaj qee qhov kev thov raws li nws tus yam ntxwv. Yog li ntawd, thaum sib tsoo, nws yog tsim nyog los xaiv ib tug haum sib tsoo log raws li ib tug tshwj xeeb qhov teeb meem (xws li cov khoom ntawm lub workpiece, kev kho cua sov txoj kev, workpiece puab, loj, ua daim ntawv thiab cov kev cai, thiab lwm yam). Txwv tsis pub, kev xaiv tsis raug ntawm kev sib tsoo lub log yuav cuam tshuam ncaj qha rau kev ua haujlwm raug, nto roughness thiab ntau lawm efficiency. Cov hauv paus ntsiab lus ntawm kev sib tsoo log xaiv tau teev tseg hauv qab no rau kev siv.
Kev xaiv ntawm abrasives Kev xaiv ntawm abrasives feem ntau yog nyob ntawm cov khoom siv ua haujlwm thiab kev kho cua sov:
Thaum sib tsoo cov ntaub ntawv nrog lub zog tensile siab, xaiv abrasives nrog siab toughness.
Thaum sib tsoo cov ntaub ntawv nrog tsawg hardness thiab siab elongation, xaiv brittle abrasives.
Thaum sib tsoo cov ntaub ntawv nrog siab hardness, xaiv abrasives nrog siab dua hardness.
Xaiv cov abrasives uas tsis yooj yim chemically reacted nrog cov ntaub ntawv ua tiav.
Feem ntau siv cov abrasives yog xim av corundum (A) thiab dawb corundum (WA), ua raws li dub silicon carbide (C) thiab ntsuab silicon carbide (GC). Lwm cov khoom siv feem ntau suav nrog chrome corundum (PA), ib leeg siv lead ua corundum (SA), microcrystalline corundum (MA), thiab zirconium corundum (ZA).
Brown corundum sib tsoo log: Brown corundum muaj siab hardness thiab siab toughness. Nws yog tsim rau kev sib tsoo hlau nrog lub zog tensile siab, xws li carbon steel, alloy steel, malleable cam khwb cia hlau, nyuaj bronze, thiab lwm yam. Nws yog feem ntau siv rau kev sib tsoo ntxhib nrog kev tshem tawm ntau dhau. Nws yog pheej yig thiab tuaj yeem siv dav.
Dawb corundum sib tsoo log: Lub hardness ntawm dawb corundum yog me ntsis siab dua li ntawm xim av corundum, tab sis nws toughness yog qis dua cov xim av corundum. Thaum txiav, cov nplej abrasive yooj yim tawg. Yog li ntawd, qhov sib tsoo cua sov yog me me. Nws yog tsim rau kev tsim kev sib tsoo log rau kev sib tsoo zoo ntawm cov hlau tawv tawv, cov pa roj carbon siab, cov hlau ceev ceev thiab sib tsoo ntawm nyias-walled qhov chaw. Tus nqi yog siab dua li cov xim av corundum.
Dub silicon carbide sib tsoo log: Dub silicon carbide yog nkig thiab ntse, nrog hardness ntau dua li dawb corundum. Nws yog tsim rau kev sib tsoo cov ntaub ntawv uas tsis tshua muaj neeg kho tshuab lub zog, xws li cam khwb cia hlau, tooj dag, txhuas thiab refractory cov ntaub ntawv.
Ntsuab silicon carbide sib tsoo log: Ntsuab silicon carbide yog nkig ntau dua li cov xim dub silicon carbide, nrog cov nplej ntse abrasive thiab zoo thermal conductivity. Nws yog tsim rau kev sib tsoo cov ntaub ntawv nyuaj thiab nkig xws li cemented carbide, optical iav thiab ceramics.
Chrome corundum sib tsoo lub log: Haum rau kev sib tsoo cov cuab yeej, ntsuas cov cuab yeej, cov cuab yeej, cov qauv thiab lwm yam khoom siv nrog cov txheej txheem ua haujlwm siab. Ib leeg siv lead ua corundum sib tsoo log: Haum rau kev sib tsoo cov ntaub ntawv uas muaj siab toughness thiab hardness xws li stainless hlau thiab siab vanadium siab ceev hlau, nrog rau cov workpieces uas yooj yim rau deform thiab hlawv.
Microcrystalline corundum sib tsoo log: haum rau kev sib tsoo stainless hlau, bearing steel thiab tshwj xeeb ductile hlau, thiab lwm yam., siv rau kev sib tsoo, txiav kev sib tsoo thiab daim iav sib tsoo.
