Qhov zoo ntawm covsib tsoo logsiv nyob rau hauv lub nto sib tsoo tshuab yog muaj feem xyuam rau cov khoom, particle loj thiab hardness ntawm lub sib tsoo log, thiab cov kev xaiv ntawm cov tsim nyog sib tsoo log yog ib qho tseem ceeb rau peb cov txheej txheem workpiece. Niaj hnub no peb ua ib qho kev piav qhia ntawm ntau yam cim ntawm kev sib tsoo log
Sib tsoo log khoom:
1. Khoom siv: A, WA, SA, PA, GC, C, 38A, DA, 19A
2, xaiv cov khoom:
A -- xim av corundum abrasive, xim av xim, siab hardness, toughness. Haum rau kev sib tsoo siab tensile lub zog hlau, xws li carbon steel, alloy steel, malleable cam khwb cia hlau, nyuaj bronze thiab hais txog.
WA -- dawb corundum abrasive, xim yog xim dawb, lub hardness yog siab dua xim av corundum, abrasive particle yog yooj yim tawg, ntug yog ntse, txiav kev ua tau zoo, sib tsoo kub me me. Haum rau kev sib tsoo thiab hardening steel, alloy steel, siab ceev steel, siab carbon steel, nyias phab ntsa, thiab lwm yam.
SA -- ib leeg siv lead ua corundum abrasives, xim yog lub teeb daj, piv nrog A, WA abrasives, siab hardness, toughness, ib qho particle spherical siv lead ua, muaj zog crushing kuj. Nws yog tsim rau kev sib tsoo impervious steel, siab vanadium high speed steel thiab lwm yam ntaub ntawv uas siab toughness thiab hardness, thiab lub workpiece yooj yim deformed thiab hlawv.
PA -- chrome corundum abrasive, rosy los yog liab doog xim, ntse txiav ntug, zoo angular tuav, siab durability. Haum rau kev sib tsoo cov cuab yeej, ntsuas cov cuab yeej, cov twj paj nruag, xov thiab lwm yam workpiece nto roughness tus nqi yuav tsum tau ua ntawm workpiece.
GC -- ntsuab silicon carbide abrasive, xim yog ntsuab, siab hardness, brittleness, ntse abrasive, muaj ib co thermal conductivity. Haum rau kev sib tsoo cam khwb cia hlau, tooj dag, txhuas, zinc thiab roj hmab, tawv, yas, ntoo, ore thiab lwm yam.
C -- dub silicon carbide abrasive, xim yog grey dub, siab hardness, brittleness, ntse abrasive, zoo thermal conductivity. Haum rau kev sib tsoo carbide, iav kho qhov muag, ceramics thiab lwm yam ntaub ntawv nyuaj thiab nkig.
Sib tsoo log loj:
← Ntug ...... 20#, 24#, 30#,... 180#, 220#, 240#... Zoo →
Sib tsoo log hardness:
← Soft E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T Hard →
Sib tsoo log mark:
Piv txwv li, kev sib tsoo lub log yog cim raws li WA46L5V351A350 × 40 × 127, qhov twg tsab ntawv code thiab cov ntaub ntawv sawv cev rau cov ntsiab lus hauv qab no:
WA → Abrasive khoom siv rau kev sib tsoo log
46 → Granularity ntawm kev sib tsoo log
L → Hardness ntawm kev sib tsoo log
5 → Sib tsoo log lub koom haum naj npawb
V → Lub log sib tsoo yog lub log sib tsoo ceramic
35 → Kab ceev ntawm kev sib tsoo log yog 35M / S
1A → Zoo li lub log sib tsoo
350 → Txoj kab uas hla ntawm kev sib tsoo log
40 → Thickness ntawm kev sib tsoo log
127 → puab qhov loj ntawm kev sib tsoo log
Yog tias koj xav tau ntau yam duab sib tsoo, koj tuaj yeem hu rau peb lossis nyem qhov txuas hauv qab no kom paub txog peb cov khoom.
