Vim tias tsis zoo rau txoj kev sib tsoo (polishing) lub teeb log, sib tsoo (polishing) lub teeb thiab polishing tus neeg saib xyuas, tshwj xeeb tshaj yog thaum qhov kev sib dhos polishing yog loj lossis lub sijhawm sib tsoo ntev dhau lawm, qhov npoo ntawm cov khoom ua haujlwm yuav tsum tawm mus tsaus nti, uas yog feem ntau hu ua "Burnt" luam. Yog hais tias nws yog immersed nyob rau hauv cov kua electrolytic polishing thiab coj tawm, nws yog dlaim phaj thiab qhia tau hais tias muaj cov cim khiab xim dawb. Qhov no yog los ntawm kev daig ntawm cov khoom ua haujlwm thiab lub log log. Thaum ib qho txhuas khoom muaj txhij txhua, nws yog feem ntau daws tau los ntawm txoj kev hauv qab no.
a. Slight alkali corrosion nyob rau hauv ib dilute dilution alkali.
b. Siv cov kua qaub me ntsis, xws li kua chromic acid-sulfuric acid, los sis 10% ntawm cov tshuaj sulfuric acid kom sov.
c. Ib feem loj ntawm 3% ammonium carbonate thiab 2% sodium phosphate solution, kho ntawm kub ntawm 40-50 ° C. Lub sijhawm yog 5 min, thiab qhov hnyav yuav raug ncua mus txog 10-15 min.

Tom qab ntxuav thiab qhuav los ntawm cov kev kho mob saum toj no, nws yuav tsum tau rov ua kom zoo dua tam sim ntawd nrog ib txoj kab zoo nkauj los yog ib daim iav polishing log. Yuav kom tsis txhob muaj teeb meem zoo li no, cov hauv qab no yuav tsum tau muab sau tseg thaum ua haujlwm.
(1) Xaiv lub thauv uas tsis haum los yog lub log tsheb. Lub log polishing los yog lub log polishing yog ib qho nyuaj heev. Vim tias cov hniav sib tsoo loj heev, nws yog ib qho yooj yim mus hlawv cov nplaim ntawm lub chaw ua hauj lwm, tshwj xeeb tshaj yog cov khoom ua haujlwm hauv tsev. Yog hais tias qhov kev lag luam yog qhov tsis zoo, lub undulating nto ntawm lub convex thiab concave yuav tsum hauv av. Conversely, yog hais tias lub log polishing yog mos heev, cov khoom uas siv cuaj hlau nyob hauv tus neeg saib xyuas polishing tsis tuaj yeem nrog kev sib txuas nrog cov khoom ua haujlwm. Thaum lub sij hawm txhuam, cov txhuas txhuas txhaws thiab cov khoom siv zom zaws qis rau lo ntug txhuam, ua rau lub nraub qaum txhuam. Yog li ntawd, tus neeg teb xov tooj yuav tsum tau npaj cov kev tawm tswv yim thiab qhov tsim nyog polishing siab thiab ceev.
(2) Xaiv ib tus neeg saib xyuas kev sib raug zoo tsim nyog. Lub binder nyob rau hauv lub polishing tus neeg raug cuam tshuam lub npoo ntawm cov khoom ua haujlwm. Muaj txhuas profiles yog tib hom polishing tus neeg sawv cev. Yog hais tias cov ntawv nyeem tsis txaus, qhov kev sib tsoo ntawm qhov sib tsoo yuav raug txo kom tsawg thiab qhov ci ntsa iab yuav tau siab. Yog hais tias koj nce lub feem ntawm lub nplaum, feem ntau, lub sib tsoo yuav sharper, tab sis lub lubrication yog zoo. Cov roj ntsha ntev tshaj nyob hauv lub koom haum polishing yuav ua kom cov nplais ntawm cov khoom ua haujlwm qias, uas tsis yog qhov zoo rau kev tshuaj xyuas kev txhuam zoo thiab ntxuav tu. Seb nws yog zoo li lub nplaum lo tshuaj los yog ib tus neeg haus dej ua kua tshuaj, nws yuav tsum tau ua rau me me tab sis ntau zaus. Tom qab lub kauj vuam hlau txav mus kom txaus txaus polishing, tus nqi ntawm kev sib tsoo txo thiab lub teeb raug pov tseg. Ntawm qhov tsis sib xws, yog tias tus neeg saib xyuas polishing ntau dhau los, lub tshuab ntuav yog yooj yim mus ncav thaum nws tuaj rau hauv kev sib txuas nrog cov workpiece, uas tsis tsuas cuam tshuam cov polishing, tab sis kuj ua rau cov khoom pov tseg thiab tsub kom tus nqi.
(3) Lub sij hawm sib tsoo ntawm lub chaw ua hauj lwm thiab txoj kev ntiv taw yuav tsum kom zoo. Nyob rau hauv qhov yooj yim mechanical phau ntawv ua haujlwm, raws li tus neeg tau kev paub ntawm tus neeg teb xov tooj
