(1) Tshaj-polishing Qhov teeb meem loj tshaj plaws nyob rau hauv cov txheej txheem niaj hnub polishing yog "dhau-polishing", uas txhais tau hais tias lub sij hawm polishing ntev dua, qhov zoo ntawm cov pwm saum npoo. Muaj ob hom kev polishing: "txiv kab ntxwv tev" thiab "pitting." Kev polishing ntau dhau feem ntau tshwm sim hauv cov tshuab polishing.
(2) Yog vim li cas rau "txiv kab ntxwv tev" ntawm lub workpiece
Irregular thiab ntxhib nto yog hu ua "txiv kab ntxwv peels". Muaj ntau qhov laj thawj rau "txiv kab ntxwv tev". Feem ntau ua rau carburization tshwm sim los ntawm overheating los yog overheating ntawm pwm nto. Ntau dhau polishing siab thiab polishing lub sij hawm yog lub ntsiab ua rau "txiv kab ntxwv tev".
Piv txwv li: polishing log polishing, lub tshav kub tsim los ntawm polishing log tuaj yeem ua rau "txiv kab ntxwv tev".
Cov hlau tawv tawv tuaj yeem tiv taus ntau dua polishing pressures, thaum cov hlau kuj softer yog feem ntau overpolishing. Cov kev tshawb fawb pom tau hais tias lub sij hawm rau overpolish nws txawv nyob ntawm seb lub hardness ntawm cov khoom steel.
(3) Kev ntsuas los tshem tawm "txiv kab ntxwv tev" ntawm lub workpiece
Thaum pom tias qhov zoo ntawm qhov chaw tsis zoo polished, ntau tus neeg yuav ua rau kom lub polishing siab thiab ncua lub sij hawm polishing, uas feem ntau ua rau saum npoo zoo dua. qhov txawv. Qhov no tuaj yeem kho tau siv:
1. Tshem tawm ntawm qhov tsis xws luag, qhov sib tsoo particle loj me ntsis coarser dua ua ntej, siv cov xuab zeb tooj, thiab tom qab ntawd zom dua, lub zog polishing qis dua lub sijhawm kawg.
2. Kev ntxhov siab yog nqa tawm ntawm qhov kub qis tshaj qhov kub ntawm qhov kub ntawm 25 ℃. Ua ntej polishing, siv cov xuab zeb zoo los zom kom txog thaum ua tiav cov txiaj ntsig zoo, thiab thaum kawg maj mam nias thiab txhuam.
(4) Yog vim li cas rau qhov tsim ntawm "pitting corrosion" nyob rau saum npoo ntawm lub workpiece yog hais tias ib co non-metallic impurities nyob rau hauv cov hlau, feem ntau nyuaj thiab brittle oxides, yog rub tawm los ntawm cov hlau nto thaum lub sij hawm polishing txheej txheem, tsim micro. - pits los yog pitting corrosion.
coj mus rau "
Lub ntsiab tseem ceeb ntawm "pitting" yog raws li nram no:
1) Lub polishing siab loj heev thiab lub sij hawm polishing ntev dhau lawm
2) Lub purity ntawm cov hlau tsis txaus, thiab cov ntsiab lus ntawm cov impurities nyuaj yog siab.
3) Pwm nto yog xeb.
4) Cov tawv dub tsis raug tshem tawm
