Taw qhia ntawm ntau yam pob zeb diamond sib tsoo log abrasives
Nov 20, 2021
Pob zeb diamond sib tsoo log yog ib qho kev sib tsoo lub log ntawm cov kev sib tsoo, thiab pob zeb diamond sib tsoo log muaj kev xaiv nruj ntawm abrasives. Cov nram qab no luv luv qhia txog ntau yam siv pob zeb diamond sib tsoo log abrasives
1, Chromium steel jade lub hardness ntawm chromium steel jade zoo ib yam li cov dawb corundum thiab lub toughness yog zoo dua (nruab nrab ntawm cov xim av corundum thiab dawb corundum), yog li lub durability thiab sib tsoo efficiency ntawm lub sib tsoo log yog siab tshaj li ntawm dawb corundum. Nyob rau tib lub sijhawm, lub contour ntawm abrasive txiav ntug ntawm qhov chaw sib tsoo lub log tuaj yeem khaws cia rau lub sijhawm ntev tom qab txiav (uas yog, abrasive txiav ntug yog nyob rau ntawm lub dav hlau kawg ntawm tib lub voj voog). Yog li ntawd, nyob rau hauv tib yam kev mob, qhov nto tiav ntawm lub workpiece hauv av nrog chromium corundum sib tsoo log yog me ntsis siab dua li nrog dawb corundum sib tsoo log. Vim yog cov yam ntxwv saum toj no, chromium steel jade yog tsim rau kev sib tsoo txhua yam ntawm cov hlau tawv tawv, ntsuas cov cuab yeej thiab cov cuab yeej ntsuas nrog cov kev xav tau siab. Tsis tas li ntawd, nws kuj yog tsim rau kev sib tsoo thiab txiav cov cuab yeej. Chromium steel jade nqe Daim phiaj yog siab thiab yuav tsum tsuas yog siv rau kev sib tsoo zoo.
2, Ib leeg siv lead ua corundum (GD) thiab microcrystalline corundum (GW) ib leeg siv lead ua corundum muaj siab hardness thiab toughness thiab zoo crushing kuj thaum sib tsoo. Nws yog siv rau kev sib tsoo stainless hlau thiab high-temperature high-speed steel. Nws muaj cov nyhuv zoo dua thaum sib tsoo steel nrog siab hardness. Microcrystalline corundum muaj lub zog siab thiab toughness, thiab nws tus kheej sharpening cuab yeej zoo dua li ib qho siv lead ua corundum. Nws yog tsim rau kev sib tsoo stainless hlau. Cov kabmob steel thiab tshwj xeeb nodular cam khwb cia hlau kuj tuaj yeem siv rau kev sib tsoo siab.
3. Cov xim ntawm cov xim dub silicon carbide abrasive yog xim dub, qee qhov yog xiav tsaus, thiab cov ceramic sib tsoo log ua los ntawm kuj yog xim dub. Lub hardness ntawm dub silicon carbide yog siab dua li ntawm txhua yam ntawm corundum abrasive. Lub abrasive grain muaj ntse dej txiv ntseej, tab sis nws cov toughness yog tsawg thiab puas. Nws tsis tuaj yeem tiv taus lub siab ntawm cov ntaub ntawv nrog lub siab toughness, yog li nws tsim nyog rau kev sib tsoo cov ntaub ntawv uas tsis muaj zog tensile los yog cov ntaub ntawv mos.
4. Cov xim ntawm ntsuab silicon carbide yog ntsuab, thiab cov ceramic daim ntawv sib tsoo log ua nrog nws kuj yog ntsuab. Ntsuab silicon carbide muaj tib lub hardness li dub silicon carbide, tab sis nws yog nkig ntau. Nws yog tsuas yog siv rau kev sib tsoo cemented carbide. Brittle cov ntaub ntawv xws li optical iav.
5. Pob zeb diamond muaj zog dua lwm yam abrasives. Nws yog cov khoom siv nyuaj tshaj plaws uas paub tam sim no. Nws muaj kev ua tau zoo heev, tab sis tus nqi kim dhau. Nws yog tsuas yog siv los ua cov ntaub ntawv siab hardness uas nyuaj rau kev ua tiav los ntawm lwm cov abrasives. Lub sib tsoo lub log ua los ntawm cov abrasive no hu ua pob zeb diamond sib tsoo log. Nws muaj ntau yam sib txawv los ntawm kev sib tsoo log ua los ntawm corundum thiab silicon carbide abrasive.
