Ib qho kev sib piv ntawm Super-nyuaj thiab Ordinary Sib Tsoo Log

Hauv kev sib tsoo cov txheej txheem, kev xaiv ntawm kev sib tsoo log muaj qhov cuam tshuam tseem ceeb ntawm kev ua haujlwm zoo thiab zoo. Super-hard sib tsoo lub log, suav nrog pob zeb diamond thiab cubic boron nitride (CBN) sib tsoo lub log, sib txawv ntawm cov log sib tsoo zoo tib yam, xws li corundum thiab silicon carbide sib tsoo lub log, hauv ntau yam.

1. Abrasive Hardness

Ordinary sib tsoo log feem ntau siv corundum thiab silicon carbide ua abrasives. Txawm hais tias cov ntaub ntawv no nyuaj, lawv tsis nyuaj li super-nyuaj sib tsoo log. Super-hard sib tsoo lub log siv pob zeb diamond los yog cubic boron nitride (CBN) ua cov abrasives, uas muaj ib tug hardness deb tshaj li cov sib tsoo log zoo tib yam, ua rau lawv tshwj xeeb tshaj yog haum rau kev ua cov ntaub ntawv high-hardness.

2. Sib tsoo Action

Thaum lub sij hawm sib tsoo cov txheej txheem, super-nyuaj sib tsoo lub log, vim lub siab hardness thiab cov yam ntxwv ntawm lawv cov abrasives, tuaj yeem nqus tau sib tsoo ntau dua. Cov yam ntxwv no ua rau txo qhov kev pheej hmoo ntawm thermal deformation thiab kub hnyiab ntawm qhov chaw ua haujlwm thaum ua haujlwm. Nyob rau tib lub sijhawm, kev txiav lub kaum sab xis thiab qhov seem ntawm kev sib tsoo ntawm lub log yog qhov sib txawv ntawm cov sib tsoo zoo tib yam. Cov yam ntxwv tshwj xeeb no muab lub zog sib tsoo lub log kom pom tseeb qhov zoo hauv kev ua cov khoom siv siab, nrog kev ua haujlwm siab dua thiab zoo dua qhov zoo.

3. Cov duab thiab cov qauv

Kev sib tsoo lub log feem ntau yog tsim los ntawm kev sib xyaw abrasives thiab khi, thiab tuaj yeem siv rau kev sib tsoo ntawm sab hauv. Nyob rau hauv sib piv, super-hard sib tsoo log feem ntau txais yuav lub hauv paus lub cev nrog ib tug abrasive txheej, tsuas yog ib tug me me pem hauv ntej cheeb tsam yog cov sib tsoo txheej, thiab tus so yog lub hauv paus lub cev, feem ntau yog ua los ntawm hlau. Qhov kev tsim no yog ib feem kom txuag tau tus nqi thiab ib nrab los kho lub zog tag nrho thiab qhov hnyav ntawm kev sib tsoo log raws li kev xav tau.

4. Sib tsoo log hnav

Kev hnav lub log sib tsoo yog ib kauj ruam tseem ceeb los xyuas kom meej lub zog ntawm kev sib tsoo lub log kev ua haujlwm thiab kev ruaj ntseg ntawm kev sib tsoo. Nws suav nrog ob yam tseem ceeb: hnav khaub ncaws rau cov duab thiab hnav khaub ncaws kom ntse. Kev hnav khaub ncaws rau cov duab feem ntau yog tsom mus rau kev rov ua kom lub log sib tsoo cov duab thiab qhov loj me, kom ntseeg tau nws daim ntawv geometric raug thaum lub sij hawm sib tsoo ntev. Kev hnav khaub ncaws rau kev ua kom zoo yog ua tiav thaum lub log sib tsoo yog npub lossis txhaws, thiab kev sib tsoo quab yuam txo qis, txhawm rau txhim kho lub sib tsoo lub log kom zoo thiab ua haujlwm zoo.

Hauv kev hnav khaub ncaws ntawm cov log sib tsoo zoo tib yam, kev hnav khaub ncaws rau cov duab thiab cov ntse tuaj yeem ua tiav ib txhij, ua kom yooj yim rau kev ua haujlwm thiab txuag lub sijhawm. Txawm li cas los xij, rau kev sib tsoo lub log nyuaj, qhov xwm txheej txawv. Vim yog cov khoom siv ntawm super-nyuaj sib tsoo lub log, cov txheej txheem ntawm kev hnav khaub ncaws rau cov duab thiab cov ntse yuav tsum tau nqa tawm nyias. Tom qab hnav khaub ncaws rau cov duab, lub sharpness ntawm super-nyuaj sib tsoo log tej zaum yuav raug cuam tshuam, thiab ces zoo tib yam sib tsoo log los yog roj pob zeb yuav tsum tau siv rau kev hnav khaub ncaws tom ntej rau sharpness los kho nws cov kev sib tsoo zoo.

Tau kawg, yog tias kev ua haujlwm sib tsoo tsis xav tau kev ua haujlwm siab, lub log sib tsoo tuaj yeem hnav ncaj qha rau kev sib tsoo kom tau raws li cov kev xav tau sib tsoo yooj yim. Feem ntau, kev hnav khaub ncaws ntawm lub log sib tsoo yog ib qho txheej txheem zoo thiab tseem ceeb uas yuav tsum tau hloov pauv raws li hom kev sib tsoo thiab kev sib tsoo.

5. Cov khoom siv ua haujlwm ua haujlwm

Super-hard sib tsoo log yog tshwj xeeb tshaj yog haum rau kev ua cov ntaub ntawv siab hardness, xws li hardened steel thiab hard alloys. Txawm li cas los xij, rau cov hlau mos, xws li cov hlau tsis muaj zog, qhov kev siv ntawm cov hlau sib tsoo hnyav yuav nce ntxiv, thiab lawv cov txiaj ntsig kev ua tau zoo yuav txo qis. Tsis tas li ntawd, vim lub siab sharpness ntawm super-nyuaj sib tsoo log, nto roughness tom qab sib tsoo cov hlau mos yuav tsis zoo. Yog li ntawd, nws yog ib qho tsim nyog yuav tau xaiv qhov tsim nyog raws li cov khoom siv ntawm lub workpiece thaum xaiv lub log sib tsoo.

6. Qhov zoo thiab qhov tsis zoo sib piv

Qhov zoo ntawm cov log sib tsoo zoo tib yam (corundum thiab silicon carbide sib tsoo lub log) yog qhov yooj yim rau hnav, muaj peev xwm ua tau zoo, thiab muaj peev xwm zom ob qho tib si mos thiab tawv hlau; thaum qhov tsis zoo yog hnav sai dua thaum sib tsoo cov ntaub ntawv nyuaj, qhov loj me yuam kev, thiab yooj yim los tsim cov kev ntxhov siab thiab thermal deformation ntawm workpieces. Qhov zoo ntawm super-nyuaj sib tsoo log (pob zeb diamond thiab CBN sib tsoo lub log) yog hnav tsawg dua thaum sib tsoo cov ntaub ntawv nyuaj, hnav khaub ncaws ntev ntev, yooj yim kom tau txais qhov loj me me thiab qis thermal deformation ntawm workpieces; tab sis qhov tsis zoo yog tsis yooj yim rau hnav rau hauv cov duab, xav tau kev ua haujlwm ntau dua, tsis haum rau kev ua cov hlau mos, thiab qis dua versatility.

Nyob rau hauv cov ntsiab lus, super-hard sib tsoo lub log thiab zoo tib yam sib tsoo lub log muaj qhov sib txawv tseem ceeb hauv abrasive hardness, sib tsoo kev txiav txim, cov duab thiab qauv, hnav khaub ncaws txoj kev, thiab cov khoom siv ua haujlwm. Hauv kev siv tswv yim, nws yog ib qho tsim nyog yuav tsum xaiv qhov tsim nyog raws li cov kev xav tau tshwj xeeb thiab cov khoom siv ntawm lub workpiece.
