(1) dhau los-polishing qhov teeb meem loj tshaj plaws uas tau tshwm sim hauv txhua hnub cov txheej txheem ua ke yog "Polishing" dhau los, qhov tsis zoo ntawm cov pwm saum npoo av. Muaj ob hom kev tshaj-polishing: "txiv kab ntxwv tev" thiab "pitting." Kev polishing ntau heev tshwm sim hauv kev siv tshuab polishing.
(2) Vim li cas rau "txiv kab ntxwv tev" ntawm lub workpiece
Cov chaw tsis tu ncua thiab ntxhib yog hu ua "txiv kab ntxwv peels". Muaj ntau ntau yam rau "txiv kab ntxwv tev duab". Qhov ua tau tshaj plaws yog carburization tshwm sim los ntawm kev kub ntxhov los yog overheating ntawm pwm nto. Kev ua kom ntau dhau polishing thiab polishing lub sij hawm yog lub ntsiab ua rau "txiv kab ntxwv tev".
Piv txwv li: Polishing log polishing, cov cua sov tsim los ntawm lub log polishing tuaj yeem yooj yim ua rau "txiv kab ntxwv tev".
Cov hlau tawv tawv tuaj yeem tiv thaiv ntau dua polishing nias, thaum cov neeg sib tw softer no tau nquag hla dhau. Cov kev tshawb fawb tau pom tias lub sijhawm dhau los sib txawv raws li lub hardness ntawm cov khoom siv steel.
(3) ntsuas los tshem tawm cov "txiv kab ntxwv tev" ntawm workpiece
Thaum nws pom tias qhov chaw zoo tsis zoo, ntau tus neeg yuav nce polishing siab thiab ua kom tiav lub sijhawm polishing, uas feem ntau ua rau cov npoo zoo dua. Qhov sib txawv. Qhov no tuaj yeem raug kho tau siv:
1. Tshem tawm cov chaw puas tsuaj, kev sib tsoo particle me me yog qhov sib txuas me ntsis dua li ua ntej, thiab tom qab ntawd zom cov xuab zeb ntxiv, lub zog polishing yog qis dua lub sijhawm kawg.
2. Kev ntxhov siab nyem yog nqa tawm ntawm qhov ntsuas kub tshaj qhov ntsuas kub ntawm 25 ℃. Ua ntej polishing, siv cov xuab zeb kom zoo kom zom kom txog thaum muaj cov nyhuv txaus siab tau ua tiav, thiab thaum kawg maj mam nias thiab txhuam.
(4) Yog vim li cas rau kev tsim "pitting corrosion" nyob rau saum npoo ntawm workpiece yog tias qee qhov tsis sib xws ntawm cov hlau thaum lub sij hawm polishing, sib sau cov roj ntsha lossis pitting corrosion.
ua rau "
Lub ntsiab lus tseem ceeb ntawm "pitting" yog raws li hauv qab no:
1) cov kev siab ua ke yog qhov loj heev thiab lub sijhawm polishing ntev dhau lawm
2) Lub purity ntawm tus hlau tsis txaus, thiab cov ntsiab lus ntawm kev impurities nyuaj yog qhov siab.
3) Cov pwm saum npoo yog xeb.
4) Cov tawv dub tsis raug tshem tawm
