Thaum siv lub tshuab tsis siv neeg polishing los txhuam cov khoom hlau, koj feem ntau ntsib ntau yam teeb meem, xws li: ntau dhau kev polishing," txiv kab ntxwv tev" ntawm qhov workpiece, thiab" pitting corrosion" nyob rau saum npoo ntawm workpiece. Peb yuav daws qhov teeb meem no li cas?
1. Tshaj polishing
Cov teeb meem loj ntsib hauv cov txheej txheem niaj hnub polishing yog" tshaj-polishing", uas txhais tau tias ntev lub sijhawm polishing, qhov tsis zoo ntawm cov pwm nto. Muaj ob yam tshwm sim uas ntau dhau ntawm polishing tshwm sim: namely," txiv kab ntxwv tev" thiab" pitting" ;. Ntau polishing tshwm sim feem ntau hauv mechanical polishing.
2. Qhov ua rau" txiv kab ntxwv tev" hauv qhov haujlwm
Cov lus saum npoo tsis meej hu ua" txiv kab ntxwv tev" ;. Muaj ntau lub laj thawj rau" txiv kab ntxwv tev" ;. Cov nquag muaj tshwm sim los ntawm kev kub siab dhau ntawm lub pwm nto lossis ntau dhau lub carburization. Lub zog polishing yog qhov loj heev thiab lub sijhawm polishing ntev dhau. Vim li cas tseem ceeb rau" txiv kab ntxwv tev" ;. Piv txwv: polishing log polishing, lub tshav kub uas tsim los ntawm lub log polishing tuaj yeem yooj yim ua" txiv kab ntxwv tev" ;.
Cov hlau tsis tshua muaj zog tuaj yeem tiv taus ntau dua qhov ua haujlwm siab polishing, thiab cov hlau tsis tshua muaj txhawm nquag nquag. Cov kev tshawb fawb pom tau tias lub sijhawm rau tshaj-polishing yuav txawv nyob ntawm seb qhov nyuaj ntawm cov hlau.
Kev ntsuas kev tshem tawm" txiv kab ntxwv tev" ntawm lub workpiece
Thaum nws pom tias cov khoom zoo saum npoo tsis zoo, ntau tus neeg yuav nce lub siab ntawm polishing thiab ntev lub sijhawm polishing. Qhov kev xyaum no feem ntau ua rau cov khoom zoo dua qub. Cov hau kev hauv qab no tuaj yeem siv los kho:
Txawm qhov tsis zoo, qhov loj me ntawm kev sib tsoo yog me ntsis coarser dua li cov xuab zeb dhau los, thiab tom qab ntawd zom, lub zog polishing qis dua li yav dhau los.
Relief Kev nyem siab yog ua rau qhov kub qis dua qhov ntsuas kub ntawm qhov ntsuas siab ntawm 25 ℃. Ua ntej polishing, siv cov xuab zeb zoo coj los zom rau kom txog thaum zoo txaus tiav, thiab tom qab ntawd ua polish nrog lub zog sib zog.
3. Cov laj thawj rau kev tsim" pitting corrosion" nyob rau saum npoo ntawm workpiece
Vim tias muaj qee qhov tsis yog xim hlau tsis zoo hauv cov hlau, uas feem ntau nyuaj thiab nkhaus oxides, lawv raug rub los ntawm cov nplaim hlau thaum lub sijhawm ua haujlwm polishing, tsim cov micro-pits lossis pitting. Lub hauv paus tseem ceeb uas ua rau" pitting" yog cov hauv qab no:
Cov polishing siab kuj loj dhau lawm thiab lub sij hawm polishing ntev dhau;
② Cov ntshiab huv ntawm cov hlau tsis txaus, thiab cov ntsiab lus ntawm hard impurities yog siab;
Cov nplaim ntawm cov pwm yog xeb;
Leather Cov tawv dub tsis tau hle.
