Feem ntau ntawm cov khoom siv pob zeb diamond yog siv los ua cov cuab yeej abrasive.Lub hardness ntawm pob zeb diamond tshwj xeeb yog siab, uas yog 2 zaug, 3 zaug thiab 4 npaug ntawm boron carbide, silicon carbide thiab corundum feem.Nws tuaj yeem zom cov workpieces nyuaj heev thiab muaj ntau yam zoo.Qee qhov ntawm nws cov kev siv thiab kev hnav khaub ncawsZ-LIONyuav qhia koj kawm ntxiv.
Qhov zoo
1. Kev sib tsoo siab: Thaum sib tsoo cemented carbide, nws cov kev sib tsoo zoo yog ob peb zaug ntawm silicon carbide.Thaum sib tsoo cov cuab yeej high-speed steel nrog kev sib tsoo tsis zoo, qhov nruab nrab ua haujlwm tau nce ntau dua 5 zaug;
2. High hnav tsis kam: hnav tsis kam ntawmcement sib tsoo logyog siab heev, thiab kev noj cov khoom abrasive me me, tshwj xeeb tshaj yog thaum sib tsoo nyuaj thiab nkig workpieces, qhov zoo yog qhov tseem ceeb tshaj plaws.Thaum sib tsoo hardened steel nrog pob zeb diamond sib tsoo log, nws hnav tsis kam yog 100-200 npaug ntawm cov khoom siv dav dav;Thaum sib tsoo cov alloys nyuaj, nws yog 5,000-10,000 npaug ntawm cov khoom siv dav dav;
3. Kev sib tsoo me me thiab qhov sib tsoo qis: Lub hardness thiab hnav tsis kam ntawm pob zeb diamond abrasive hais yog siab heev, cov khoom abrasive tuaj yeem nyob twj ywm rau lub sijhawm ntev, thiab nws yooj yim los txiav rau hauv lub workpiece.Thaum sib tsoo carbide nrog resin-bonded pob zeb diamond sib tsoo log, kev sib tsoo quab yuam tsuas yog 1/4 mus rau 1/5 ntawm kev sib tsoo quab yuam ntawm kev sib tsoo zoo tib yam.Lub thermal conductivity ntawm pob zeb diamond yog siab heev, 17.5 npaug ntawm silicon carbide, thiab txiav cov cua sov yog kis tau sai, yog li qhov sib tsoo kub yog tsawg.Piv txwv li, siv cov silicon carbide sib tsoo lub log rau kev sib tsoo cemented carbide, txiav qhov tob yog 0.02 hli, qhov sib tsoo kub yog siab li 1000 ℃ ~ 1200 ℃, thiab pob zeb diamond sib tsoo log nrog resin daim ntawv cog lus yog siv rau kev sib tsoo.Nyob rau tib lub sijhawm, qhov sib tsoo ntawm qhov kub tsuas yog 400 ℃;
4. Kev sib tsoo workpiece muaj siab precision thiab zoo nto zoo: thaum sib tsoo cov cuab yeej carbide nrog pob zeb diamond sib tsoo lub log, qhov roughness ntawm lub ntsej muag thiab cov hniav yog qis dua li nrog silicon carbide sib tsoo lub log.ntse heev, lub durability ntawm cov hniav tuaj yeem nce los ntawm 1 mus rau 3 zaug.Lub workpiece ua tiav nrog pob zeb diamond sib tsoo log feem ntau muaj qhov roughness Ra tus nqi ntawm 0.1 ~ 0.025μm, uas tuaj yeem txhim kho los ntawm 1 ~ 2 qib piv nrog cov kev sib tsoo zoo tib yam.
Daim ntawv thov
Pob zeb diamond sib tsoo logyog dav siv los grind high-hardness cov ntaub ntawv thiab precious cov ntaub ntawv uas yog nyuaj rau grind nrog zoo tib yam sib tsoo log thiab yuav tsum tau zoo.Non-metallic workpieces xws li sib tsoo thiab txiav cemented carbide, ceramics, iav, agate, gemstones, semiconductor cov ntaub ntawv, pob zeb kuj haum rau titanium alloys.
Txoj kev hnav khaub ncaws
Vim lub siab hardness ntawm pob zeb diamond thiab kev ua haujlwm zoo, kev sib tsoo log feem ntau tsis tas yuav hnav.Txawm li cas los xij, tom qab lub sijhawm siv, cov chips raug thaiv, kev ua haujlwm tau txo qis, thiab txawm tias lub zog sib tsoo loj, qhov sib tsoo kub nce ntxiv, thiab lub log sib tsoo tawg.Tom qab kev sib tsoo log yog clogged, nws yuav tsum tau trimmed.Thaum hnav khaub ncaws, lub pob zeb diamond sib tsoo lub log tuaj yeem ua tiav nrog silicon carbide lossis corundum whetstone.Txoj kev yog hu rau lub tiaj tus silicon carbide lossis corundum oilstone nrog lub pob zeb diamond sib tsoo.Thaum lub sij hawm sib tsoo, vim lub siab hardness ntawm lub pob zeb diamond sib tsoo log, silicon carbide los yog corundum oilstone tuaj yeem ua hauv av, thiab silicon carbide lossis corundum oilstone yuav tshem tawm cov pob zeb diamond.Cov chips ntawm lub log sib tsoo rov qab txiav kev ua haujlwm ntawm lub log sib tsoo.
Cov saum toj no yog cov ntsiab lus hais txog qhov zoo, kev siv thiab kev hnav khaub ncaws ntawm pob zeb diamond sib tsoo log sib koom nrog koj.Kuv vam tias los ntawm cov ntsiab lus saum toj no, koj tuaj yeem muaj kev nkag siab ntxiv thiab kev nkag siab ntawm pob zeb diamond sib tsoo log.
