Xaivtxiav log, txhua tus zoo li nyiam cov qauv tawg. Txawm li cas los xij, hauv kev ua lag luam, kev tsim kho qhov teeb meem koj ntsib yog qhov sib txawv, cov khoom siv ntawm cov khoom siv sib txawv, thiab cov khoom siv ntawm super nyias ob lub mesh.txiav discsiv kuj txawv.
Ib qho zoo super nyias ob npaug mesh txiav disc yuav tso cai rau koj kom tau txais ob zaug qhov tshwm sim nrog ib nrab ntawm kev siv zog thaum ua haujlwm workpieces. Ib qho zoo super nyias ob lub mesh txiav disc yuav tsum tsis muaj peb yam no.
Kev sib tsoo tus nqi ntawm thawj cov khoom, qhov kev sib tsoo ntawm cov khoom yog dab tsi?
Kev sib tsoo piv yog hais txog kev txiav kev ua haujlwm ntawm kev sib tsoo lub log. Qhov tsawg dua qhov kev sib tsoo lub log (nrog rau cov nqi rov qab), qhov ntau ntawm cov khoom raug txiav, qhov sib tsoo ntau dua, thiab qhov kev ua tau zoo ntawm cov khoom sib tsoo. Txoj kev suav yog: sib tsoo log poob ntim / workpiece tshem tawm ntim. Raws li cov ntaub ntawv txheem ntawm kev sib tsoo piv, qhov poob tus nqi kuj txawv vim muaj ntau hom kev sib tsoo log (ceramic, resin, roj hmab, iab pob zeb diamond, thiab lwm yam). Kev sib tsoo kom raug ntau dua tuaj yeem tau txais los ntawm kev ntxiv cov khoom xws li qib abrasive, qhov loj me, kev sib koom ua ke, softness thiab hardness, cov ntaub so ntswg ntom ntom, thiab ntau yam khoom sib txuas.
Basic tswvyim:
Qhov piv ntawm cov khoom tshem tawm tus nqi ntawm lub workpiece rau qhov hnav tus nqi ntawm kev sib tsoo log yog hu ua kev sib tsoo piv.
Sib tsoo tshwj xeeb zog:
Sib tsoo lub zog tshwj xeeb Es yog hais txog lub zog siv ib lub sijhawm los tshem tawm ib chav tsev ntawm cov khoom siv ua haujlwm. Feem ntau nws tuaj yeem qhia tau tias: Es=Pmvwapb qhov twg: Pm yog kev siv hluav taws xob
Sib tsoo Ratio:
Sib tsoo ratio G=Vwc/Vsc
Nyob rau hauv cov mis: Vwc - lub ntim ntawm lub workpiece mus rau hauv av;
Vsc - poob ntim ntawm lub log sib tsoo.
Sib tsoo piv yog ib qho tseem ceeb thiab feem ntau qhia txog kev siv nyiaj txiag ntawm kev sib tsoo lub log. Kev sib tsoo qhov sib piv yog ntau dua li ntawm Yu, uas txhais tau hais tias kev sib tsoo lub log ntawm qhov hnav lub cev kev kuaj xyuas lossis kev ua haujlwm zoo tuaj yeem zom cov hlau ntau dua, thiab kev siv lub log sib tsoo yog kev lag luam ntau dua.
Txij li thaum lub log sib tsoo yog tsim los ntawm peb lub ntim xws li abrasive daim ntawv cog lus thiab qhov hws, lub ntim Vsc ntawm lub log sib tsoo hnav kuj suav nrog peb qhov ntim. Qee lub sij hawm lub tswv yim ntawm hnav piv Φ kuj tseem siv los qhia txog kev lag luam ntawm kev sib tsoo log hauv kev siv.
Wear ratio Φ=Vsc/Vwc
Nws tuaj yeem pom los ntawm cov qauv saum toj no tias qhov hnav piv yog qhov sib txuam ntawm kev sib tsoo. Kev sib tsoo piv tuaj yeem qhia txog kev sib tsoo ntawm cov khoom siv, thaum qhov sib piv feem ntau qhia txog kev hnav tsis kam ntawm kev sib tsoo log.
Qhov thib ob yog los saib cov yam ntxwv ntawm cov khoom. Nws tseem yog ib qho tseem ceeb heev uas yuav tau xaiv cov khoom uas muaj cov yam ntxwv zoo li cas ntawm ib puag ncig.
Kev hnav khaub ncaws ntawm superabrasive sib tsoo lub log yog txawv ntawm cov sib tsoo zoo tib yam. Kev hnav khaub ncaws yog muab faib ua ob theem: shaping thiab sharpening. Cov theem shaping yog hais txog kev ua haujlwm ntawm qhov sib tsoo log muaj qhov yuav tsum tau geometric raug ntawm cov duab thiab qhov chaw. Lub sharpening theem yog hais txog kev tshem tawm ntawm cov khoom sib txuas ntau dhau ntawm cov khoom siv superhard abrasive rau ntawm qhov chaw ua haujlwm ntawm kev sib tsoo lub log los ntawm kev sib tsoo, kom cov nplej abrasive raug rau qhov siab tshaj plaws, kom qhov chaw ua hauj lwm ntawm kev sib tsoo log. muaj kev sib tsoo zoo. Tau ntev, ntau tus kws tshawb fawb tau ua ntau yam kev tshawb fawb txog kev hnav khaub ncaws ntawm superabrasive sib tsoo log, thiab tsim ntau txoj kev hnav khaub ncaws zoo, feem ntau suav nrog kev hnav khaub ncaws, hluav taws xob machining hnav khaub ncaws thiab lwm yam kev hnav khaub ncaws. Cov txheej txheem siv tshuab feem ntau suav nrog txoj kev tig, txoj kev sib tsoo, txoj kev dov trimming, pob zeb diamond roller trimming txoj kev; Cov txheej txheem ua hluav taws xob feem ntau suav nrog txoj kev txiav electrolytic thiab hluav taws xob hluav taws xob trimming txoj kev; Lwm txoj kev trimming xws li laser trimming txoj kev, ultrasonic trimming txoj kev, thiab lwm yam.
