Yam dab tsi txiav txim siab qhov zoo ntawm pob zeb diamond vitrified sib tsoo log? Peb tuaj yeem tham txog nws los ntawm ob yam ntawm pob zeb diamond abrasive thiab daim ntawv cog lus tsim.
1. Pob zeb diamond abrasive
Lub pob zeb diamond abrasive yog sib npaug ntawm qhov chaw ua haujlwm ntawm kev sib tsoo lub log, uas qhia txog qhov tshwm sim ntawm cov pob zeb tawg, uas muaj qhov muaj zog txiav. Thaum xaiv cov abrasives, nws yog qhov zoo dua los xaiv cov ntaub ntawv siv lead ua tsis zoo thiab qhov chaw ntxhib, txhawm rau txhim kho lub zog tuav ntawm tus neeg sawv cev ntawm cov pob zeb diamond abrasives. Tsis tas li ntawd, lub thickness ntawm lub pob zeb diamond abrasive yuav cuam tshuam ncaj qha rau qhov roughness ntawm polished workpiece nto thiab kev sib tsoo efficiency, thiab nws kuj muaj feem xyuam rau qhov poob ntawm cov cuab yeej abrasive. Txhawm rau ua kom tau raws li qhov yuav tsum tau ua ntawm cov khoom ua haujlwm, cov pob zeb diamond ntxhib ntxhib yuav tsum tau siv ntau li ntau tau, txhawm rau txhim kho kev sib tsoo thiab txo qis hnav.
2. Binder tsim
Lub luag haujlwm ntawm daim ntawv cog lus vitrified yog los khi cov abrasive. Lub thermal stability ntawm pob zeb diamond abrasive tsis zoo, thiab nws yuav raug oxidized thaum nws siab tshaj 700 degree hauv huab cua. Hauv qhov chaw tiv thaiv, tom qab cua sov ntawm 900 degree, lub zog compressive kuj yuav txo qis. Ntawm no, qhov hluav taws kub kub ntawm vitrified daim ntawv cog lus yog npaj. Kev xav tau - tsis siab dhau. Tsis tas li ntawd, kev nthuav dav coefficient ntawm cov neeg sawv cev sib txuas yuav tsum ua kom haum rau cov thermal expansion coefficient ntawm abrasive, thiaj li ua tau raws li kev ua haujlwm lub zog ntawm kev sib tsoo log, thiab thermal conductivity ntawm tus neeg sawv cev sib txuas yuav tsum tsis txhob ua kom tsis zoo.
Daim ntawv cog lus yuav tsum muaj lub zog tuav ntawm lub pob zeb diamond abrasive. Pob zeb diamond muaj peev xwm tiv taus siab thiab muaj lub neej ua haujlwm ntev. Txhawm rau muab kev ua si tag nrho rau qhov zoo ntawm pob zeb diamond abrasives thiab txo cov nqi ua haujlwm, kev tsim qauv tsim qauv tsim nyog yog qhov tseem ceeb.
