Nyob rau hauv cov txheej txheem machining ntawm ob -sided grinder, vim hais tias lub luag haujlwm tseem ceeb ntawm cov khoom abrasive yog txiav, khawb thiab zawv zawg, feem ntau ntawm cov khoom abrasive raug txiav tawm, uas ua rau lub ntsej muag ntawm lub workpiece muaj qhov kub thiab txias hauv siab { {1}}kev sib tsoo ceev. Nyob rau hauv qhov kev txiav txim ntawm qhov kub siab dua, cov qauv metallographic ntawm lub workpiece nto yuav hloov tau zoo heev, uas yuav hloov qhov hardness ntawm lub workpiece thiab thaum kawg cuam tshuam rau kev ua haujlwm ntawm lub workpiece.
Nyob rau tib lub sijhawm, vim muaj cov xim sib txawv ntawm cov oxide zaj duab xis ntawm qhov chaw ua haujlwm, qhov tshwm sim ntawm kev sib tsoo kub yog qhov hloov pauv ntawm cov khoom siv ntawm qhov chaw ua haujlwm, feem ntau yog vim qhov kub ntawm qhov chaw kho mob siab. Thaum lub workpiece nto mus txog qhov kub thiab txias, nws yooj yim rau hlawv.
Txhawm rau soj ntsuam cov txheej txheem combustion ntawm qhov chaw ua haujlwm, nws yog qhov yuav tsum tau ntsuas qhov nruab nrab ntawm qhov chaw ua haujlwm ntawm qhov sib txawv. Qhov kev ntsuam xyuas no ua lub luag haujlwm tseem ceeb hauv kev daws cov teeb meem ntawm kev tswj kev sib txuas thiab kev kwv yees hauv kev tsim khoom. Qhov tseeb tau ua pov thawj tias kev sib tsoo hlawv yog ib qho kev hloov maj mam. Nyob rau hauv lub dav hlau grinder thiab polishing tshuab, qhov kub thiab txias yuav hloov, thiab cov txheej txheem kub yuav ua tiav nyob rau hauv ib lub sij hawm luv luv. Nws yuav sawv. Nws yuav tsum tau muab sau tseg tias qhov kub ntawm no yuav hloov tam sim ntawd. Nyob rau hauv qhov tseeb, nws yog reflected nyob rau hauv cov kauj ruam hloov ntawm kub ntawm ob sab, thiab ob yog tib yam. Yog tias tsuas yog qhov ntsuas kub ntawm qhov no tau tshwm sim, muaj qee qhov teeb meem hauv kev txiav txim siab qhov kub hnyiab.
Thaum qhov kub ntawm qhov chaw ntawm lub workpiece nce maj mam los ntawm qhov qis mus rau qhov siab, thiab qhov kub thiab txias nce mus txog lossis tshaj qhov kub ntawm cov khoom siv ua haujlwm, qhov kub hnyiab ntawm lub workpiece pib tshwm.
Nyob rau hauv cov txheej txheem ntawm ob -sided grinder, yog tias cov kua sib tsoo tsis yog siv los ua kom txias, lub hardness ntawm workpiece nto txheej yuav txo qis thiab qhov hardness ntawm workpiece nto txheej yuav tsum annealed. Nyob rau hauv cov xwm txheej ceev ceev nrog polishing kua, nto ntawm lub workpiece yuav quenched thiab hlawv thaum sib tsoo. Yog hais tias qhov kub ntawm qhov chaw ntawm lub workpiece yog ntau tshaj ib tug tej yam kev mob, kub ceev yuav tshwm sim.
Lub ntsiab ua rau kub hnyiab yog kub sib tsoo. Kev kub hnyiab feem ntau cuam tshuam nrog qhov kub thiab txias. Vim muaj ntau yam cuam tshuam rau lub workpiece kub, kub hnyiab tau cuam tshuam rau qee yam. Yog hais tias lub workpiece nrog tsis zoo combustion kev ua tau zoo yog yooj yim rau hlawv thaum lub sij hawm combustion, lub burning thiab sib tsoo log yuav raug cuam tshuam. Yog hais tias lub hardness ntawm lub sib tsoo log yog siab, tus kheej sharpening kev ua tau zoo tsis zoo thiab kub yuav tshwm sim. Yog li ntawd, kev sib tsoo lub log yuav tsum tau siv los txo qhov kub hnyiab. Yog siv cov xuab zeb ntxhib, nws tsis yooj yim rau hlawv. Yog tias peb xav txhim kho lub sijhawm cua sov thiab cua sov dissipation tej yam kev mob, nws yuav muaj qee yam cuam tshuam rau kev kub nyhiab heev. Tom qab cov slurry tau txias tag, nws yog qhov zoo heev los tiv thaiv kev kub nyhiab thiab tawg.
