Cov txheej txheem ntawm kev ua haujlwm tuaj yeem muab faib ua: "kev tshem tawm" ntawm cov ntaub ntawv txiav, "ua tiav" ntawm cov ntaub ntawv melting thiab txhaj rau hauv pwm, "kev ua yas" ntawm kev siv pwm rau deform cov ntaub ntawv, thiab "sib koom / txiav ua" ntawm koom lossis txiav cov khoom sib cais. Cov txheej txheem ntawm kev tshem tawm ib feem ntawm cov khoom ntawm lub workpiece yog hu ua kev tshem tawm. Kev sib tsoo yog ib qho ntawm lawv, uas tshem tawm cov khoom nto ntawm lub workpiece los ntawm kev kub ceev rotating sib tsoo log. Thaum lub sij hawm sib tsoo, yuav tsum muaj ib qho khoom siv hu ua grinder. Txawm hais tias nws yuav siv sij hawm ntev dua li kev txiav nrog cov cuab yeej, nws tuaj yeem tsim tau ntau dua thiab zoo nkauj ua haujlwm. Kev sib tsoo feem ntau yog siv los ua cov txheej txheem tiav rau lwm txoj kev machining. Piv txwv li, tom qab txiav mus rau ib qho kev ntxhib los mos, qhov chaw ntawm lub workpiece tuaj yeem txhim kho los ntawm kev sib tsoo. Kev sib tsoo tseem tuaj yeem ua cov ntaub ntawv nyuaj uas nyuaj rau kev txiav, xws li cov alloys nyuaj. Qee zaum, kev sib tsoo kuj tuaj yeem siv los ua cov txheej txheem siab hardness tom qab quenching.
Qhov zoo thiab qhov tsis zoo ntawm kev sib tsoo
Kev sib tsoo ua haujlwm muaj qhov zoo thiab qhov tsis zoo hauv qab no.
Qhov zoo ntawm kev sib tsoo ua haujlwm
High precision nyob rau hauv machining qhov ntev
Vim tias tsuas yog me me ntawm cov khoom yuav tsum tau muab tshem tawm thaum lub sij hawm txhua txoj kev sib tsoo, high-precision machining tuaj yeem ua tiav. Cov tshuab sib tsoo tuaj yeem siv los tsim cov micrometer qhov loj thiab ua rau lawv smoother.
Machinable cov ntaub ntawv nyuaj
Kev sib tsoo yog hais txog kev siv ntau cov khoom abrasive uas tawm los ntawm qhov chaw sib tsoo los txiav qhov saum npoo ntawm lub workpiece. Thaum lub sij hawm sib tsoo cov txheej txheem, txawm tias ib qho abrasive grain tawg, tom ntej no abrasive grain yuav cia li raug nthuav tawm (tus kheej sharpening nyhuv), yog li lub sib tsoo log yeej ib txwm ntse. Txawm hais tias cov khoom abrasive yog softer dua li cov khoom ua haujlwm, kev ua haujlwm tuaj yeem txuas ntxiv mus.
tuaj yeem txhim kho qhov roughness
Thaum lub sij hawm txiav, cov khoom nto ntawm lub workpiece yuav maj mam tawm, uas tuaj yeem ua rau saum npoo du heev.
Disadvantages ntawm kev sib tsoo
Lub sijhawm ua haujlwm ntev heev
Qhov zoo ntawm kev sib tsoo yog tias nws tuaj yeem ua tiav high-precision machining, tab sis qhov tsis zoo yog tias nws siv sijhawm ntev los ua kom tiav. Yog li ntawd, cov workpieces loj feem ntau yog tsim los ntawm kev txiav thiab tom qab ntawd ua tiav los ntawm kev sib tsoo.
Yooj yim los tsim kom muaj cua sov thaum ua haujlwm
Thaum lub sij hawm sib tsoo, qhov kub ntawm qhov chaw sib tsoo tshaj 1000 degrees vim yog kev sib txhuam ntawm lub log sib tsoo thiab cov khoom ua haujlwm. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau siv cov kua txiav ua kom txias txias ntawm lub workpiece kom tsis txhob hlawv thiab tawg.
Cov xwm txheej yuav tshwm sim thaum ua haujlwm
Vim muaj kev sib hloov ceev ntawm lub log sib tsoo thaum lub sijhawm sib tsoo, ntau yam xwm txheej tuaj yeem tshwm sim yog tias lub log tsis siv kom zoo. Ceev faj tsis txhob tshaj qhov siab tshaj plaws kev sib hloov ceev ntawm lub sib tsoo lub log, thiab tsis txhob nias lub workpiece nyuaj heev rau lub sib tsoo log.
